5×7 Photo Size: Pixels, Inches and Aspect Ratio

5 × 7 photo measures 127 × 177.8 mm. Its pixel dimensions change with PPI; the physical trim size does not.

Quick answer

A 5 × 7 inch photo measures 127 × 177.8 mm and needs 1500 × 2100 pixels at 300 PPI. Its 5:7 ratio crops about 6.7% of a typical 3:2 camera frame when filled edge to edge.

Crop warning

A 3:2 photo loses about 6.7%

A 3:2 image is slightly wider than a 5:7 frame. Filling the print retains about 93.3% of the image area; fitting the whole image may leave borders.

Before ordering

Protect faces and text near the edge

Photo labs can apply a small production crop beyond the ratio calculation. Keep critical details away from the edge and confirm border options.

Print setup

Trim first. Add production values second.

5 × 7 identifies the final physical format. Bleed expands the artwork beyond that edge; a safe margin moves important content inward. Those extra values depend on the print provider.
