What is the best image size for Facebook, Instagram, TikTok and YouTube?
The short answer
As of October 2026: for an Instagram or Facebook feed post, use 1080 × 1350 pixels (4:5 portrait) — it takes the most room on a phone; 1080 × 1080 square also works. For Stories, Reels, TikTok and YouTube Shorts, use 1080 × 1920 (9:16 vertical). For a YouTube thumbnail or a landscape video, use 1280 × 720 or 1920 × 1080 (16:9).
SSS Social’s free image resizer turns any picture into these sizes in your browser, without uploading it.

Why portrait wins on phones
Most people scroll on a phone held upright. A 4:5 picture fills more of the screen than a square or a landscape one, so it is more likely to stop the scroll. Keep text and faces away from the edges, where some screens trim.
