How to use it with the calculators
Ratios are more stable than exact pixel counts, so match the ratio first and the pixels will fit even when a platform bumps its resolution. Need a size that is not on the sheet? Open the ratio's calculator, enter one dimension, and read the other — or start from the main aspect ratio calculator. For the full guide with per-platform notes and an FAQ, see the Social Media Aspect Ratio Cheat Sheet.
Need an exact custom size?
Enter a width or height for any ratio and read the matching dimension instantly.
