Social Media Image Sizes 2026: The Complete Cheat Sheet (All Platforms)
Every platform has different image size requirements. Posting the wrong size means cropped faces, blurry banners, or rejected uploads. Here's the definitive reference.
The Cropped Face Problem
You upload a group photo to Facebook. Half the faces are cropped out. You resize for Twitter — it's now letterboxed with black bars. You try Instagram — the resolution is too low and it looks blurry. Different platforms, different rules.

Step-by-Step: Resize for Social Media

- Or enter custom dimensions
- Toggle "Lock aspect ratio" to prevent distortion
- Download the resized image
Pro Tips
- Start large: Always resize down, never up. Upscaling makes images blurry.
- Portrait > Square > Landscape: On Instagram, portrait (4:5) gets 30% more engagement than landscape (1.91:1)
- Safe zone: Keep important content in the center — edges get cropped on different devices
- Text in images: Use at least 24px font size — smaller text becomes unreadable after compression
