Prepare a gallery-wrap canvas
Calculate enough image area to cover the front, stretcher sides and a small rear-edge allowance.

When to use it
Start with the result you need
This calculator is most useful when one part of the print specification is known and another needs to be checked.
Create a mirrored-edge file
Identify the full production dimensions before generating or extending the wrap area.
Quote canvas artwork requirements
Give a client exact physical and pixel dimensions for the selected frame depth and print density.
The calculation
How it works
The artwork must extend past every edge of the visible face: full size = finished size + 2 × (stretcher depth + extra bleed). The result is then converted to pixels using the selected PPI.
A 24 × 36 inch canvas with a 1.5 inch gallery wrap and 0.25 inch extra bleed needs artwork measuring 27.5 × 39.5 inches before converting to pixels.
Quick reference
Common canvas-wrap decisions
Canvas providers use different stretcher bars, wrapping methods and recommended resolution. Their template takes priority.
| Setting | Common range | What it controls | Check before export |
|---|---|---|---|
| Stretcher depth | 0.75–1.5 in | Visible side of frame | Measure the actual bar |
| Extra bleed | 0.125–0.5 in | Rear-edge tolerance | Use provider template |
| Print density | 100–300 PPI | Pixel requirement | Depends on size and process |
| Safe content area | Front face | Text and focal points | Keep away from fold |
| Wrap treatment | Image, mirror or colour | Appearance of sides | Choose before cropping |
Some providers specify a fixed wrap allowance that differs from the stretcher depth. Enter their stated value when available.
Check the numbers
24 × 36 inch canvas, 1.5 inch wrap
With 0.25 inch extra bleed, the artwork becomes 27.5 × 39.5 inches. At 150 PPI it needs 4125 × 5925 pixels.
40 × 60 cm canvas, 3 cm wrap
Adding 0.5 cm extra bleed per edge produces a full file of 47 × 67 cm before conversion to pixels.
12 × 12 inch square canvas
A 1.25 inch wrap plus 0.25 inch extra bleed adds 3 inches to both dimensions, producing a 15 × 15 inch artwork file.
Before you export
Common mistakes to avoid
Using the face size as the document size
The canvas needs additional image area on all four edges. A face-only file leaves the wrap blank or forces enlargement.
Putting text in the wrap zone
Keep lettering, signatures and faces inside the front-face safe area unless the side placement is intentional.
Assuming every provider wraps identically
Rear stapling, mirrored edges and frame depths vary. Confirm the exact template before final production.
Calculate canvas wrap, bleed and artwork pixels. FAQ
How much image should wrap around a canvas?
At minimum, allow for the stretcher-bar depth on every side. Many providers also request a small additional bleed that reaches around the rear edge.
What PPI should a canvas print use?
It depends on canvas size, texture, viewing distance and provider workflow. Values from 150 to 240 PPI are common planning targets, but use the printer’s specification.
Does the wrap area need important image content?
Usually no. Important content should remain on the front face. The wrap can use extended image, mirrored edges or a solid colour depending on the desired finish.
