How to Measure a Canvas for a Floating Frame Accurately

Use the outside dimensions of the stretched canvas itself. A metal tape measure and millimetres will give you the clearest, most repeatable measurements.

  • Measure the stretched canvas, not an existing frame
  • Measure the outside edges of the stretcher bars
  • Use a metal tape measure where possible
  • Measure in millimetres
  • Use a clean, level surface
  • Double-check before ordering
1 Width and Height

Measure the Width and Height of Your Canvas

When learning how to measure a canvas for a floating frame, begin with the true outside dimensions of the stretched canvas. Measure the width from the far left edge to the far right edge, then measure the height from the top edge to the bottom edge.

Include the complete wooden stretcher structure beneath the canvas. Do not measure only the visible artwork and do not add an allowance for the floating gap, as our frame designer calculates this automatically.

Professional Tip

Always measure twice before ordering.

Enter the actual canvas width and height only. The frame designer automatically allows for the approximately 5mm shadow gap.

Measure the Canvas Depth

Measure from the front face of the stretched canvas to the back of the wooden stretcher bar. This depth measurement is just as important as the width and height because it determines which floating frame profile will comfortably contain your canvas.

Select a frame depth equal to or slightly greater than the canvas depth. If your measurement falls between two available depths, choose the deeper option so the front of the canvas does not project beyond the frame.

Step 3

Enter Your Canvas Measurements Online

Once you have carefully checked the width, height and depth, you are ready to order. Enter the actual measurements exactly as taken from your stretched canvas; there is no need to add anything for the shadow gap or frame opening.

Before adding the frame to your basket, compare the measurements with your notes one final time. Because every floating frame is made specifically to the dimensions you provide, accurate measurements help ensure the best possible fit.

Frequently Asked Questions
Do I measure the canvas or the existing frame?

Always measure the stretched canvas itself. Do not measure an existing floating frame or other outer frame.

Should I measure in inches or millimetres?

We recommend millimetres because they allow greater accuracy.

What if my canvas depth falls between two sizes?

Choose a frame with an internal depth equal to or slightly greater than the canvas depth.

Can you help me if I am unsure?

Yes. Contact us before ordering and our experienced framing team will be happy to help.

What happens if I enter the wrong size?

A correctly manufactured bespoke frame cannot normally be returned because customer-supplied measurements were incorrect.

How much clearance is inside the floating frame?

We normally allow an approximately 5mm shadow gap around the canvas.
