Common photo aspect ratios
3:2 matches many cameras and 4×6-inch prints. 4:3 is common on phones. 5:4 fits 8×10-inch prints, while 1:1 is square. Never stretch a photograph to force a ratio.
Crop without losing family details
- Keep an uncropped master before making print-specific versions.
- Leave space around handwritten borders, studio mounts and inscriptions.
- Use different crops for social sharing and archival preservation.
