Calculate Dimensions for Social Media

Instagram Feed: 1:1 (square, 1080×1080), 4:5 portrait (1080×1350), or 1.91:1 landscape (1080×566). Stories: 9:16 (1080×1920).

Twitter post images display at 16:9 for single images. Twitter profile header: 3:1 (1500×500). Profile photo: 1:1.

Use the presets panel at the bottom — click any platform name to instantly load those dimensions into the calculator.

When cropping a photo to a specific ratio, calculate the exact pixel dimensions first, then crop to those values in your image editor.
