How to Frame a Canvas: The Complete Guide for Stretched Canvas Art

Canvas art needs a different frame than paper art. The canvas already has depth, so it needs a frame that wraps around the sides instead of pressing the front under acrylic.

Most picture framing is built for flat artwork, photos, prints, posters, certificates. You press the artwork under acrylic, mat it for breathing room, and seal it inside a shallow frame. Canvas is different. A stretched canvas already has depth (the canvas itself is wrapped around a wooden stretcher bar 0.75 to 1.5 inches deep), and the paint sits on the surface, not under glazing.

This guide covers how to frame a stretched canvas, paintings, canvas prints, photo prints on canvas, using a floater frame, which is the standard framing solution for any stretched canvas.

Step-by-Step Guide to Framing a Stretched Canvas

A regular picture frame is shallow. The rabbet (the L-shaped groove in the back of the frame) holds flat artwork pressed against acrylic. If you tried to put a stretched canvas in a regular frame, the canvas would not fit, it is too deep, and even if it did, the painted surface would press against the glazing and damage the paint.

A floater frame solves this. The floater frame is deeper, with an open channel running around the inside instead of a closed rabbet. The canvas drops into the channel from behind and sits with a small gap (the "float") between the canvas edge and the inside wall of the frame. The painted face stays fully exposed. No glazing. No mat. The canvas appears to float inside the frame, hence the name.

What you need to frame a canvas

1. A stretched canvas. The canvas must be mounted on wooden stretcher bars. If your canvas is loose (unstretched), it needs to be stretched first by an art supply shop or framer.
2. A floater frame. Sized to fit your canvas with a small reveal gap on all four sides. Browse our canvas floater frames to size yours.
3. A measuring tape. Measure the canvas depth (front to back) to pick the right frame depth.
4. Offset clips or screws. Most floater frames come with the hardware to attach the canvas. If yours did not, an art supply shop sells them in packs.

Step 1: Measure your canvas

Measure three things:

• Width, the horizontal dimension across the front of the canvas.
• Height, the vertical dimension up the front of the canvas.
• Depth, the side thickness from the front of the canvas to the back. Most canvases are 0.75 inch (gallery-thin) or 1.5 inch (gallery-wrapped) deep.

Write all three measurements down. You will use width and height to size the frame and depth to make sure the canvas fits inside the floater frame channel.

Step 2: Pick the right floater frame

Floater frames come in two width configurations:

• Same-size floater, the inside opening matches your canvas size exactly. The canvas drops in flush. No visible reveal gap. Looks like a tight modern frame.
• Oversized floater, the inside opening is 1/4 to 1/2 inch larger than your canvas in each direction. This creates a small visible gap around the canvas, the "float", that makes the canvas appear to hover inside the frame.

Pick the depth based on your canvas depth. The floater frame should be at least as deep as your canvas, and ideally 1/8 to 1/4 inch deeper so the canvas sits cleanly recessed inside.

For canvas finishes:

• Natural wood, gallery-modern, warm, neutral.
• Black, bold, dramatic, makes color pop.
• White, clean, contemporary, fades into the wall.
• Gold or silver leaf, formal, traditional, gallery-style.

Step 3: Place the canvas in the frame

Lay the floater frame face-down on a clean flat surface. Set the canvas face-down into the open back of the frame. The canvas should sit inside the inside channel of the frame.

If you have an oversized floater, center the canvas inside the frame so the reveal gap is even on all four sides. A small wedge of cardboard or folded paper in each corner gap will hold the canvas centered while you secure it.

Step 4: Secure the canvas to the frame

Most floater frames come with offset screws, short screws with an L-shaped bracket that grips the back edge of the stretcher bar and pulls it tight against the frame. Use three screws per side: one near each corner and one in the middle.

Drive the screws through the back of the frame into the stretcher bar. Do not overtighten, the wood can split. Hand-tighten until the canvas feels firm.

If your frame did not come with hardware, use mending plates or offset clips from an art supply shop. The goal is to hold the canvas firmly without pulling the frame out of square.

Step 5: Add hanging hardware

Most floater frames come with a sawtooth hanger pre-installed on the back. For canvases larger than 16×20, upgrade to D-rings and picture wire, they spread the weight across two anchor points on the wall.

Mount the D-rings about 1/3 of the way down from the top of the frame on each side. String picture wire across the back with a few twists at each ring. The wire should be tight enough that it does not hang below the top of the frame.

How to frame a canvas painting (extra notes)

The same process works for an original canvas painting. Two extra notes:

• Let the paint cure. Oil paint takes weeks to months to fully cure. Acrylic paint cures in a few days. Wait until the paint is dry to the touch and not tacky before framing.
• Be gentle with the surface. Avoid touching the painted face. Set the canvas face-down on a soft cloth when working.

How to frame a canvas print or photo on canvas

Canvas prints and photos on canvas are framed the same way as a painting. The advantage of canvas over framed paper is that there is no glazing, no glare, no reflections, no risk of breakage. A floater frame finishes the look without changing the print.

Common mistakes

• Picking a frame that is too shallow. If the floater frame is shallower than the canvas, the canvas sticks out the back. Always measure depth.
• Overtightening the offset screws. Splits the stretcher bar wood.
• Putting glazing over a canvas. Don't. Canvas is meant to be viewed bare. Glazing adds glare and traps moisture.
• Skipping the reveal gap. If you want the floating look, pick an oversized floater. A flush fit looks like a regular tight frame.

When you should not use a floater frame

If your canvas is loose (unstretched), like a rolled poster, you cannot use a floater frame. The canvas needs to be stretched onto bars first, or framed flat under acrylic like a paper print.

If you want glazing protection, say, for a valuable original painting being shipped, you can frame the canvas in a deep shadow box with a stand-off spacer that keeps the acrylic from touching the paint. This is less common but possible.

Frequently asked questions

How do you frame a canvas without a frame?

Stretched canvas was originally designed to display bare on the wall. You can hang the canvas directly using picture wire and D-rings on the back of the stretcher bars. No frame needed. This is called gallery-wrap and it's how most modern canvas art is displayed.

Can you put a stretched canvas in a regular picture frame?

No. Stretched canvas is too deep (0.75 to 1.5 inches) to fit in a regular picture frame rabbet. Use a floater frame designed for canvas, or hang the canvas bare.

How much does it cost to frame a canvas?

A custom floater frame costs 50 to 250 dollars depending on canvas size, frame width, and finish. Floater frames in standard finishes (natural wood, black, white) at 16×20 inches start around 70 to 100 dollars. Larger sizes and ornate finishes cost more. Configure your canvas frame to see live pricing for your dimensions.

Do canvas paintings need glazing?

No. Canvas paintings are meant to be viewed without glazing. The paint is durable on the canvas surface and glazing creates glare. Only add glazing to a canvas if it is valuable and being stored long-term in a museum-style display.

How deep should a floater frame be?

The floater frame depth should match or slightly exceed your canvas depth. For a 0.75 inch deep canvas, pick a floater frame 0.875 to 1 inch deep. For a 1.5 inch deep canvas, pick a 1.625 to 2 inch deep frame.

What is the difference between a floater frame and a regular frame?

A regular frame has a closed rabbet that pinches flat artwork from the front. A floater frame has an open channel that holds stretched canvas from the back, leaving the painted face fully exposed. Floater frames have no glazing and no mat.
