3 required values are still missing.
Common photo print sizes do not share one aspect ratio
| Print size | Ratio | What happens to a 3:2 camera image |
|---|---|---|
| 4×6 | 3:2 | No ratio crop |
| 5×7 | 7:5 | Some width is cropped |
| 8×10 / 16×20 | 5:4 | More width is cropped |
| 8×12 / 12×18 / 20×30 / 24×36 | 3:2 | No ratio crop |
What the result is useful for
Gallery Wrap Calculator helps make the physical framing or crop consequence visible before ordering a print, mat, canvas or frame.
How the calculation works
Required image size = front-face dimensions + twice the wrap allowance on each axis.
What this calculator cannot know
A ratio calculation cannot choose the best composition automatically. Faces and important subjects may require an off-center crop, and frames/mats can have manufacturer-specific overlaps.
