8 × 10 photo measures 203.2 × 254 mm. Its pixel dimensions change with PPI; the physical trim size does not.
An 8 × 10 inch photo measures 203.2 × 254 mm and needs 2400 × 3000 pixels at 300 PPI. Its portrait 4:5 shape is wider relative to height than a portrait 2:3 camera image.
300 PPI: 2400 × 3000 px · aspect ratio 4:5Portrait values are rounded to the nearest whole pixel after converting the native physical dimensions.

Filling a portrait 8 × 10 frame with a portrait 2:3 image retains about 83.3% of the image area. Reposition the crop to protect the subject.
Preview the 8 × 10 cropAn 8 × 10 requires 1200 × 1500 px at 150 PPI, 1920 × 2400 px at 240 PPI or 2400 × 3000 px at 300 PPI.
Check your fileOnce an image is cropped to 4:5, it also fits a 16 × 20 frame by ratio—but the larger print needs more pixels for the same PPI.
Open 16 × 20The 8 × 10 is a traditional portrait, certificate and small wall-display format. It is usually viewed closely, so skin detail, eyes, text and retouching deserve more scrutiny than they would on a distant-viewed poster.
Its 4:5 ratio removes about 16.7% of a portrait 2:3 camera image when filled. The crop is substantial enough to cut shoulders, hands or environmental context. Recompose deliberately, use a 4:5 camera crop when available, or fit the whole image with a border.
At 300 PPI, the trim needs 2400 × 3000 pixels. The same 4:5 crop also fits 16 × 20 by shape, but doubling each physical edge doubles the pixel requirement for equal PPI. Do not assume one exported file is equally dense at both sizes.
For this 8 × 10 example, the printer requests 3 mm bleed on every edge and a 5 mm safe margin inside trim. The artwork canvas becomes 209.2 × 260 mm, or 2471 × 3071 pixels at 300 PPI. The protected region is 193.2 × 244 mm. These are example production requirements, not part of the paper standard.
Set the trim before placing the layout, extend the real background into bleed, and keep faces, lettering and other essential content inside the provider’s safe margin. A raster canvas and a PDF with page boxes describe the same physical job differently; do not scale all artwork simply to include an export border.
Recalculate with your printer’s exact margins8 × 10 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.
Calculate bleed and safe areaUse the source pixels, final orientation and intended crop for portraits, certificates and framed wall photos; then confirm the required PPI with the provider.
