5:4 aspect ratio
1.2500:1 · 1280×1024 px · also called 1.25:1, 8x10 ratio
5:4 sits between square and 4:3. It is the ratio of 8×10 inch prints and of older 1280×1024 monitors, and it appears in catalogue and print-adjacent workflows more than in paid social.
What 5:4 means
A 5:4 frame is 1.25 times wider than it is tall. Multiply the width by 4/5 to get the height. Exact sizes: 1000×800, 1280×1024, 2000×1600.
Where it is used
Print catalogues, 8×10 in photo prints, legacy display inventory and some in-app placements.

Working with 5:4
- 01Crop to 1:1 for marketplaces rather than padding — the loss is only 20% of the width.
- 02At 300 DPI, 8×10 in is 2400×3000 px in portrait or 3000×2400 px in landscape.
- 03Do not confuse with 4:5 — the same numbers in the other order produce a portrait frame.
