If you have a stretched canvas sitting against a wall right now, you can put it into a proper floater frame this weekend, with a hand drill, a set of offset clips or four screws, and about half an hour. The hardest part is not cutting anything or buying anything. It is making sure the shadow gap around the edges comes out even.
That gap is the whole point of a floater frame. Because the frame has no lip at the front, the canvas sits inside it rather than behind glass, and a sliver of shadow appears on all four sides. Done well, the painting looks like it is hovering a centimetre above the wall.
Most of what you find on this topic online is written by sellers of the frame being installed, and nearly all of it stops before the hard questions: where the moulding actually comes from, what to do when the canvas is too thin to screw into, and how to fix a gap that is 2 mm wider at the top than at the bottom. This guide walks the whole arc of how to frame a canvas painting yourself, from what a floater frame is through sourcing, assembly, installation, hanging and troubleshooting, updated for 2026.

What Is a Floater Frame?
A floater frame, also called a floating frame, is a deep picture frame with no front lip, designed to hold a stretched canvas by its stretcher bars so the canvas appears to hover inside the frame with a visible gap, or shadow gap, on all four sides.
The same object is sold under three names, and they are interchangeable: floater frame, floating frame, and shadow gap frame. Some sellers also call the inner raised edge a fillet, which is a slightly different profile. A true floater has nothing at the front at all.
Here is how the mechanism works, in three parts:
- No front lip. The frame attaches to the back or the sides of the stretcher bars, so the full painted surface and the canvas edge stay visible from every angle.
- A shadow gap of roughly 1/8 to 1/4 inch. That narrow band of wall, lit from one side and shaded on the other, is what creates the floating effect. Too narrow and the gap disappears. Too wide and the painting looks lost inside the frame.
- Depth that matches the canvas. The frame is deep enough to sit proud of the wall by the thickness of the stretcher bars, usually 3/4 inch, 1-1/2 inch or 1-3/4 inch, so the frame face projects out from the canvas rather than sitting behind it.
One term worth knowing before you buy anything. The rabbet, also spelled rebate, is the recessed ledge on the inside face of a traditional frame that the artwork sits against. A floater frame has no rabbet at the front, because there is no front. The canvas is held from the back by hardware and the depth comes from a step or riser block built into the sides of the frame.
The stretcher bars are the wooden frame the canvas is stretched over. Their depth, measured from front painting surface to back edge, is the canvas depth, and it is the single number that decides which floater frame will fit.
For most people the whole job is three decisions: match the frame depth to the canvas depth, hold the canvas square inside that depth, and hang it level. Everything else is detail.
Floater Frame vs. Traditional Frame vs. Shadow Box
This is the question that comes up most often, and the honest answer is that these three solve different problems. A traditional frame is for paper and flat images. A shadow box is for objects with physical depth. A floater frame is specifically for a stretched canvas or a panel.
| Feature | Floater frame | Traditional frame | Shadow box |
|---|---|---|---|
| Front lip | None | Yes, usually 1/4 to 1 inch | Yes, with glazing |
| Shadow gap | 1/8 to 1/4 inch on all sides | No gap, lip overlaps artwork | Deep interior void |
| Holds | Stretched canvas, canvas board, wood panel | Paper, prints, flat art, matted work | 3D objects, memorabilia, dried flowers |
| Glazing | Not used | Usually glass or acrylic | Glass or acrylic, sealed |
| Cleaning | Dry dust or soft cloth, no glass | Glass needs regular cleaning | Glazing needs cleaning and dust control |
| Common failure | Uneven gap, loose hardware | Glass breakage, mould under glazing | Cloudy acrylic, trapped moisture |
| Best for | Oil or acrylic on stretched canvas | Works on paper, prints, drawings | Collectibles and layered pieces |
Two practical warnings. First, never put a stretched canvas into a glazing frame with glass. The canvas is not flat, and the stretcher bars push forward against the glass under changes in humidity, which is how glazing cracks.
Second, if your work is a canvas print on a rigid panel, a floater frame is overkill. A traditional frame with a mat looks more like a print and less like a painting, and painters in the framing forums are the first to say so.
What You’ll Need to Frame a Canvas Painting Yourself
There are two routes, and the difference is whether you buy a finished frame or cut your own.
Route one, pre-made frame. This is what most people should do. You need the frame itself, cut to the outside size of your canvas plus a small margin, plus a flat work surface at least as large as the canvas.
- A floater frame, deep enough for your canvas (measure before ordering)
- Offset clips or swivel clips, two per side, or four screws with washers
- A drill or screwdriver
- A spirit level and a tape measure
- Cardboard spacers or riser blocks if the frame has no built-in step
- Two small blocks to rest the canvas on while you work
Route two, building the frame yourself. Add these to the list:
- Floater frame moulding sold as L-profile lengths, or hardwood suitable for routing a rabbet
- Wood glue, PVA
- A band clamp or corner clamps
- A miter saw with a fine-tooth blade, or a miter box and hand saw
- A router with a rabbet bit, if you are cutting the step into solid wood yourself
- 120 and 220 grit sandpaper, plus a file or rasp
- Finish of your choice: paint, stain, or clear coat
Two tools people forget. Sharp screws, because a stripped screw head halfway through a hardwood frame ruins a visible corner. And a square, because a frame that is one degree out of square at the miter will show every time the light changes.
Warning: hardwood does not accept screws driven straight in. Pre-drill every hole with a bit slightly smaller than the screw, or the screw will split the moulding along the grain. Softwood will take a hand-driven screw, hardwood will not.
How to Frame a Canvas Painting in a Floater Frame
This is the full install, start to finish. It works for a pre-made frame and for a frame you assembled yourself.
Step 1. Measure your canvas at two depths. Measure the outside width and height across the front of the stretcher bars, then measure the depth from the painting surface to the back edge. Write both numbers down. The first is your visible size, the second decides the frame depth.
Step 2. Check the frame before you put anything in it. Lay the frame face down on a flat surface. Run a flat edge or a straightedge across the opening to confirm it is square and the inner step is even on all four sides. A frame with a twisted corner will give you four different gaps no matter how carefully you work.
Step 3. Plan the gap before you place anything. Decide on a target, usually 1/8 to 1/4 inch per side. For a 20 inch canvas that means the frame opening should be roughly 20-1/2 inches. A simple frame usually leaves a fixed inset, so buy a size that produces the gap you want, or add riser blocks to move the canvas backward.
Step 4. Dry-fit the canvas with spacers. Place your riser blocks or cut cardboard spacers on the step inside the frame, set the canvas face down on top of them, and nudge it until the gap looks even all the way around. Step back a metre and look again. This is the step that decides whether the finished frame looks professional.
Step 5. Lock the position. With the canvas sitting correctly, mark the spacer positions lightly in pencil so you can reproduce the alignment, then lift the canvas straight up and out without twisting it.
Step 6. Attach the hardware. Fix offset clips or swivel clips to the inside faces of the frame, two per side, positioned so the notched jaw clears the stretcher bar. Clip jaws are angled on purpose, so set them all to the same orientation. If you are using screws instead, pre-drill, drive a countersunk screw with a washer into each stretcher bar, and stop the moment it is snug.
Step 7. Re-seat the canvas. Turn the frame face down, lower the canvas onto the spacers, and press the stretcher bars down until every clip snaps over its bar. Work around the frame once rather than hammering one corner at a time.
Step 8. Check the gap from a low angle. Kneel at floor level and sight along the top edge, then the bottom. You are looking for light coming through anywhere, which means a gap that is uneven. Adjust by swapping spacer thicknesses rather than by pushing the canvas sideways.
Step 9. Re-verify the fit and let it settle. Check that the clip on each corner is fully seated and the canvas is not being pinched, which can bow the stretcher bars over weeks. If the frame is pre-assembled, add picture hanging hardware now while the back is still accessible.
The whole active process takes about half an hour per canvas. The measuring and the sitting-back-to-look step are the parts worth taking your time over.
How to Attach the Canvas: Screws, Clips or Glue
There are four ways to secure a canvas in a floater frame, and they are not equally good. Glues vary a lot depending on whether your substrate is wood, MDF or aluminium.
| Method | Hold strength | Risk to artwork | Reversible | Best for |
|---|---|---|---|---|
| Offset or swivel clips | Strong | None to the painting face | Yes, lift and slide out | Most canvases, all thicknesses |
| Screws into stretcher bars | Very strong | Small holes in the back, split risk in hardwood | Yes, with effort | Stretched canvas with solid wood bars |
| Adhesive on built-in spacers | Permanent | Bonds the substrate to the frame | No | Canvas board and thin panels |
| Hook and loop tape | Weakens over time | Low | Yes | Temporary display only |
Clips are the default choice. They hold well, they leave no mark on the painting, and you can swap canvases inside the same frame later, which is useful if you are working through a series.
Screws are stronger but not always better. They are the right answer for a stretched canvas with solid wood stretcher bars, and the wrong answer for a thin panel, because the panel has nothing to bite into. On MDF and aluminium panels, screws simply spin.
Glue is the answer when there is nothing to screw into. This is the exact problem raised on the oil painting forums, and the workaround is well documented. The approach is to glue a set of MDF or hardwood strips to the back of the panel, let them cure, and then screw the canvas through those strips into the floater frame. The user Gator242 on r/oilpainting described precisely this setup, with the strip edges painted black so they read as part of the shadow line. A neutral-cure silicone works well on a rigid panel because it stays slightly flexible.
That strip-backer method is also what makes thin canvas board behave like a stretched canvas, and it is the single most useful trick in this whole guide if your work is on board.
Do not use hook and loop tape as a permanent fix. The adhesive degrades, loses holding strength, and lets the canvas shift out of alignment over time. It is fine for a temporary display, and it is how people end up with a painting that no longer sits square a year after framing it.
How to Get an Even Shadow Gap
An even gap is the difference between a DIY frame that looks amateur and one that looks like a gallery job. It is not about your cutting skill. It is about measurement and support.
Measure diagonally, twice. Before the canvas goes in, measure the frame opening corner to corner in both directions. If the two numbers differ, the frame is out of square and no amount of careful centring will hide it. Return it or fix the miters.
Use spacers rather than eyeballing. Cardboard spacers, wooden riser blocks, or purpose-made packers all work. Whatever you use, make the thickness identical on all four sides. A stack of 1/8 inch spacers on one corner and two 1/8 inch spacers on the other is a 1/8 inch gap error at that corner, and it will be visible.
Paper wedges work for frames with no built-in step. If your frame is a plain L-profile with no riser, slip folded paper wedges between the canvas and the inner wall on all four sides until the gap reads even. This is the low-cost method described in the Framing4Yourself assembly instructions, and it is a good reason to keep a small stack of glazing paper or kraft paper in the drawer.
Work in a circle, not in rows. Set the top edge, then one side, then the bottom, then the other side, checking the gap after each move. Setting all four edges before checking almost guarantees you end up with a parallelogram rather than a rectangle.
Sight along the surface at a low angle. This is the check most people skip. Squinting along the edge from floor height reveals ripples and a bowed stretcher bar that a straight-on view hides completely.
If the frame is too shallow for your canvas. You have three options: add riser blocks to push the canvas back, glue a deeper spacer layer to the step, or accept a narrower gap. The fourth option, cutting a wider rabbet with a router, is the one to avoid on your first attempt.
Choosing the Right Frame Depth for Your Canvas
Depth is the one specification you cannot fake. Get it wrong and the frame either will not hold the canvas or will sit so far off the wall that the floating effect collapses into a shelf.
Measure the depth of your canvas from the front painting surface to the back of the stretcher bar, then match it to the table below.
| Canvas or panel | Depth | Recommended frame depth | Notes |
|---|---|---|---|
| Shallow stretcher bar | 3/4 inch | 1-1/4 inch to 1-1/2 inch | Most gallery-stretch canvases; leave room for spacers |
| Standard deep stretcher | 1-1/2 inch | 1-7/8 inch to 2 inch | The most common size for oil paintings |
| Extra deep stretcher | 1-3/4 inch | 2-1/4 inch | Add a riser block if the frame is only 2 inch |
| Thick stretcher or cradle | 2-1/4 inch | 2-3/4 inch or deeper | Build a custom frame or fit a solid wood L-profile |
| Canvas board or thin panel | 1/8 inch to 1/4 inch | 2-3/4 inch to 3 inch | Needs tall spacers or a strip backer |
Two rules that keep it simple. Buy a frame deeper than your canvas by at least a quarter inch, so you have room for spacers. And if the frame is much deeper than the canvas, push the canvas to the back with riser blocks so the gap reads as a shadow rather than a hole.
Depth is also the main driver of cost, which is worth understanding before you wonder why a floater frame costs what it costs.
How to Build Your Own Floater Frame from Wood
This is the most-asked question in the framing forums and almost no text article answers it. People want the floater frame moulding in planks so they can cut their own sizes, the same way they would with regular frame moulding.
You have three options, in increasing order of difficulty.
Option one: buy floater frame moulding as L-profile lengths. This is the fastest route and it is what the r/framing threads recommend. The lengths come with a rabbeted or stepped face profile, and you cut four miters and assemble exactly like a normal frame. Ask for floater frame moulding or L-profile floater lengths, and specify the depth you need.
Option two: buy pre-cut frame sections and join them yourself. Suppliers will cut and miter sides to your outside dimensions. You then glue and clamp the corners, which gives you a custom size without owning a saw.
Option three: cut the step into solid wood yourself. This is the real woodworking route. You pick hardwood, rip the strips, cut your miters on a miter saw with a fine-tooth blade, then use a router with a rabbet bit to cut the step on the inside face. Test the rabbet setup on an offcut first. The bit depth sets your frame depth, and getting it wrong wastes the strip.
The assembly sequence is the same in all three cases:
- Cut four lengths to the outside dimensions you want, remembering that the miter takes material off each end.
- Dry-fit the four pieces and check the diagonals for square before any glue goes on.
- Apply a thin bead of PVA wood glue to each miter face. Not a thick layer, which squeezes out and makes the corner look soft.
- Bring the corners together with a band clamp or corner clamps. Wipe squeeze-out with a damp cloth while it is still wet.
- Let it cure fully before sanding or finishing. Overnight is safer than an afternoon.
- Sand through 120 then 220 grit, easing every sharp arris so the frame reads soft rather than hard.
- Finish with paint, stain, or clear coat, and let the finish cure before the canvas goes anywhere near it.
On hardware: softwood accepts a hand-driven screw, hardwood does not. If you are working in maple, walnut, or cherry, pre-drill every hole. A countersunk screw with a washer seated flush looks like the factory finish.
On sourcing, one more tip from r/framing. Local moulding suppliers will often open an individual wholesale account for a small business, in some cases with just a reseller licence and proof of an LLC. It is worth asking before you pay retail, and a local lumber mill may cut custom mouldings, though the lumber is mostly construction grade and not very straight, so plan on selecting your stock carefully.
How to Frame a Canvas Painting Without Power Tools
Not everyone has a miter saw, and you do not need one. This route uses a miter box, a hand saw, and 1×2 pine, and it is the version most often shared as a short social video and almost never as a written guide.
- Mark your lengths. Decide the outside dimensions and mark each cut line twice, on two faces of the pine. Measure from the end you will actually cut, not the factory end.
- Set the miter box. Clamp 1×2 pine firmly in the box and cut all four miters with a hand saw, using long even strokes. A miter box keeps the angle consistent, which is the only thing a power saw would have done for you here.
- Form the frame and check square. Glue the corners, clamp them, and measure both diagonals before the glue sets. If the diagonals differ, correct it now with a nudge while the corner is still soft.
- Add the step. Without a router, glue a thin strip along the inside face of each side to create the riser the canvas will sit against. Use a strip of the same wood, roughly 1/4 inch wide, and pin or nail it in place while the glue is wet.
- Fill and finish. Fill the nail or screw holes, sand the corners flat, and paint or stain. Pine takes paint cleanly and hides a lot of small mistakes.
The honest limitation: a hand-cut pine frame will never be as crisp as a machine-cut hardwood one, and the miters may show slightly at a raking angle. For a piece on a hallway wall, that difference disappears.
Canvas Board, Panels and Unstretched Canvas
Almost every guide on this topic is written for stretched canvas. Here is the branch that gets skipped, because it is where a lot of beginners actually are.
Canvas board and thin panels. These are typically 1/8 inch, 1/4 inch or 1/2 inch thick, with a printed or painted surface on one side. A thin panel has no stretcher bars at all, so there is nothing to screw into. Pre-installed tall spacers, or the strip-backer method described earlier, solve this. On r/oilpainting, the user Dr_Turb frames canvas-board work in a conventional rebated frame with glazing and a mount, then offers offset clips as the way to attach a floater frame to a backing panel that is thick enough to accept screws. Either approach works; the glazing route is cheaper, the floater route looks more like a painting.
Wood panels. These handle well because they are thick and screw-friendly. They need a 3 inch deep frame so the shadow gap is proportional to the small panel, otherwise the gap looks enormous next to the artwork.
Unstretched or rolled canvas. This one is a two-day job rather than an afternoon. You need to stretch the canvas onto stretcher bars yourself, pulling it evenly from all four sides and stapling or tacking it with a small margin of overlap at the back. Then let it dry under even tension for several days before framing. Do not frame a freshly rolled canvas immediately; the tension will not have settled and the gap will go out of square as it relaxes.
Already-framed work. If your piece is on a gallery-wrapped canvas with the sides painted, it can still go into a floater frame. Measure the actual depth including the painted return, and add a fraction of an inch for clearance.
Why Floater Frames Are Expensive
Four things drive the cost, and once you can name them you can decide which one to give up.
- Depth and volume of wood. A floater frame is far heavier than a traditional frame of the same length, because it is essentially a chunky L-section rather than a thin profile. You are paying for solid material, not surface area.
- Hardwood versus softwood. Hardwood moulding costs several times what pine costs, and it is harder to work, so the labour component rises too.
- Custom sizing. A standard-size frame is made in batches. A frame cut to your canvas is a one-off, and the cutting, joining and finishing time is all in that one piece.
- Surface area of large formats. Cost scales with the perimeter, so a 48 by 60 inch canvas needs roughly double the moulding of a 24 by 30 inch canvas. A large piece is expensive for arithmetic reasons, not because it is special.
This is also why building from raw lumber can undercut a finished frame: you pay for the material and your own time rather than for someone else’s cutting, glue-up and finish schedule.
One more framing-shop reality from the forums. Online custom suppliers are generally cheaper than a local shop but carry a perception of lower quality, and they are not cheap either. For a single canvas, the DIY route usually wins on cost and loses on time.
Where to Buy Floater Frames
Three sourcing routes, cheapest to most hands-on.
Off the shelf from an art supply retailer. Blicks Art Materials and Jerry’s Artarama both carry readymade floater frames in the common depths. The user IAMA_CHAD_AMA on r/framing recommends the Blick readymade floaters specifically because they arrive with pre-drilled and countersunk holes, which removes the most fiddly part of the install. Buy standard depths here, in standard sizes.
Custom cut to size. Suppliers like American Frame and the team behind PictureFrames.com will cut a frame to your exact outside dimensions. This is the route for unusual canvas sizes, deep canvases, or anything where the standard range does not reach. You get the joinery done for you and skip the saw.
Raw moulding by the linear foot or the metre. This is the answer to the most common forum question about where to get floater frame wood in planks. Ask for floater frame moulding or L-profile floater lengths, specify the depth, and cut it yourself. As mentioned earlier, ask a local supplier about a wholesale account, and check whether a local mill will cut custom mouldings.
When ordering any of the three, have three numbers ready: the outside width, the outside height, and the canvas depth. Ordering without the depth is the most common reason a frame arrives unusable.
Hanging Your Floater-Framed Canvas
Hanging is where a good frame gets ruined, and it is the step most guides reduce to a single sentence about D-rings. Here is the fuller version.
Choose hardware based on weight. A stretched canvas on standard bars is light. A 36 by 48 inch oil on a 1-3/4 inch stretcher is not, especially with a hardwood floater around it. Use a single D-ring or two D-rings set far apart, matched to the weight, rather than the small ring that came in the hardware packet.
Find the studs. Run a stud finder across the full width of where the frame will hang and mark both outer edges. A stud gives you something to drive into directly. A heavy canvas that hangs from drywall anchors alone will creep sideways over a few years, and the gap will go out of square with it.
Measure the drop before you drill. A floater frame projects out from the wall by the depth of the canvas, so the top of the frame is not where the hanging point sits. Mark the position, hold the frame up to it, and check the balance with a spirit level before you commit.
Level as you go, not at the end. Once one D-ring is fixed, level the frame before drilling the second. Trying to correct a tilted frame by shifting the second fastener is how you end up with a frame that is level but crooked inside its own opening.
Check the wall type last. Plaster, lath, and old drywall can crumble if you drill into them without knowing what is behind. If the wall is soft or hollow, use proper anchors sized for the load, and for a heavy piece attach into studs wherever you can.
For a gallery wall, hang the largest piece first, place the level across its top edge, and use that as your reference line for the rest.
How to Frame a Large or Oversized Canvas
A canvas in the region of 60 inches and up is a handling problem before it is a framing problem. Two people should carry it, one person on each side, with the frame carried on edge rather than flat, because a frame resting flat on two parallel edges will rack.
Do not try to hang a large piece with picture wire alone. Use a French cleat or a ledger board screwed into studs, with a safety lip so the frame cannot lift off. If the piece is genuinely heavy and the studs are awkwardly placed, wall anchors rated well above your actual load are the honest answer.
For very large works, the raw moulding route becomes much more attractive, since a hardwood frame long enough for a 77 by 79 inch canvas is expensive to buy cut and perfectly reasonable to assemble yourself.
Does Canvas Look Better Framed or Unframed?
Unframed, gallery-wrapped, if the sides are painted and the piece is in good light. A gallery wrap is a finished object in its own right, and a floater frame around it is a stylistic choice rather than an improvement.
Framed, if the edges are unfinished. Most stretched canvases are stapled to the bars at the back with a raw margin of fabric showing, and that looks unfinished whether or not anyone else notices. The floater frame hides the staple line behind a shadow gap without covering any of the painted surface.
Framed, if it is part of a group. A floater frame gives a mixed wall of canvases and prints a consistent outer dimension and a consistent shadow line, which is what makes a gallery wall read as intentional rather than accumulated.
The decision rule is simple: if you would be comfortable showing the sides of the canvas, leave it unframed. If you would not, frame it.
Common Mistakes and How to Fix Them
Every one of these is routine, and every one of them is avoidable if you know what caused it.
| Symptom | Cause | Fix |
|---|---|---|
| Uneven shadow gap | Frame out of square, or canvas centred by eye | Measure both diagonals, add matching spacers on all four sides |
| Gap disappears on one side | Bowed stretcher bar | Check at a low angle, replace the bar or relax the canvas tension |
| Visible canvas staples or raw fabric edge | Frame too small, or no shadow gap | Add a riser block to increase the gap, or resize the frame |
| Frame will not hold the canvas | Frame depth shallower than the canvas | Use a deeper frame, or glue in a wider spacer step |
| Corner split while driving a screw | Screw driven into hardwood without pre-drilling | Glue and clamp the corner, then pre-drill for any further screws |
| Clips will not snap on | Clip jaw set the wrong way, or spacer stack too thick | Flip the clip, or reduce spacer thickness |
| Screws spin in the panel | Thin MDF or aluminium panel with no backing | Glue on a strip backer, then screw through it |
| Mitres do not meet cleanly | Miter saw blade too coarse, or wrong stop setting | Rebuild the corner with a fine-tooth blade and a square |
| Canvas shifts over time | Hook and loop tape adhesive degrading | Replace with offset clips |
| Frame twists on the wall | Hanging on drywall anchors only | Rehang with at least one fixing into a stud |
Warning: never glue a canvas into a frame if you might ever want to remove it. Adhesive on spacers is a permanent decision, and a permanently mounted canvas cannot be re-stretched, cleaned behind, or sold separately.
Frequently Asked Questions
Can I frame a canvas painting myself?
Yes. If you can measure accurately, drill pilot holes and keep a level, you can do the whole job in about half an hour. The frame is the easy part; the even shadow gap is where beginners need the most patience. Buy a frame already cut to size rather than building one for your first attempt.
How do you attach a painting to a floating frame?
Set the canvas onto riser blocks inside the frame so the gap is even, then secure it with two offset or swivel clips per side that snap over the stretcher bars. Screws into the stretcher bars work too, as long as you pre-drill first. On a thin panel with no stretcher bars, glue on a strip backer and screw through that.
What is the difference between a canvas frame and a floating frame?
A canvas frame is just the wooden stretcher bars the canvas is stretched over. A floating frame is the decorative frame that goes around it. The floater has no front lip, so the canvas is held from the back and a shadow gap of about 1/8 to 1/4 inch shows on all four sides.
How do canvas floater frames work?
Because there is no front lip, the frame grips the stretcher bars from the back using clips, screws, or adhesive on built-in spacers. That leaves the front edge of the canvas fully visible and creates a consistent gap on all four sides. The gap casts a shadow line, which is what makes the painting look three-dimensional on the wall.
Why are floater frames so expensive?
Four reasons: they use a lot more wood than a traditional frame of the same length, hardwood moulding costs several times what softwood costs, custom cutting is a one-off labour charge, and cost scales with the perimeter so large sizes roughly double. Building from raw moulding and doing your own glue-up is the usual way to bring the cost down.
What size floater frame do I need for my canvas?
Measure the outside width and height of the stretcher bars, then add half an inch to each dimension for a 1/8 inch gap per side. Also measure the canvas depth from the painting surface to the back of the bars, because a 3/4 inch deep canvas and a 1-3/4 inch deep canvas need completely different frame depths.
How do I get an even shadow gap on a canvas frame?
Use spacers of identical thickness on all four sides rather than centring by eye, and adjust them corner by corner in a circle rather than row by row. Measure both diagonals of the frame first to confirm it is square. Paper wedges work well as cheap spacers if your frame has no built-in step.
Do floating frames look good?
They look good on stretched canvas, canvas board and wood panel, because the shadow gap makes the work read as a floating object. They are the wrong choice for a print, which is better served by a mat in a traditional frame, and they do not help a gallery-wrapped canvas whose edges are already finished.
Can you reuse a floater frame for a different canvas size?
Yes, if you use clips rather than adhesive, and only if the new canvas is within about half an inch of the old one. Lift the old canvas out, swap the spacer thicknesses to suit the new depth, and reseat it. A frame glued with adhesive is committed to that one canvas permanently.
How do you hang a heavy canvas painting?
Use a D-ring or two rated above the actual weight, and get at least one fixing into a wall stud. Mark the drop before drilling, since a floater frame sits proud of the wall by the depth of the canvas, so the hanging point is not at the top edge. Check the level after the first fixing rather than adjusting at the end.
Conclusion
To frame a canvas painting yourself, you need three numbers from the canvas: outside width, outside height, and depth. Match the first two to a frame with a 1/8 to 1/4 inch inset, match the third to the frame depth, support the canvas on matching spacers so the shadow gap comes out even, and lock it in with offset clips. Then hang it into a stud and check the level before you let go.
Everything beyond that is preference. Build the frame yourself if you enjoy it, buy it cut if you do not, and leave it unframed if the edges of your canvas are already finished.
