Social Media Image Sizes 2026: The Complete Cheat Sheet
Instagram, X, YouTube, Facebook, LinkedIn — every dimension you need, in one table.
Every platform re-encodes and crops images that don't match its specs. This cheat sheet lists the exact dimensions so your content ships pixel-perfect.

Why exact sizes matter
An oversized image gets downscaled and re-compressed — visible as softness and banding. An undersized one looks blurry on retina displays. Matching the spec avoids both.

Quick checklist before posting
- Use 1080 px on the long edge for Instagram.
- Export JPEG quality 80+ or PNG for sharp text.
- Keep the safe zones — platforms crop in feeds.
- Re-check YouTube thumbnails at small sizes (they're tiny in search).
Thumbnail text rule
Text on a 1280×720 thumbnail should be legible at roughly 120×68 px — that's how big it appears in most search results.
