Social Media Image Sizes 2026: Instagram, TikTok, YouTube, LinkedIn and More
A current social media image-size reference with feed, story, video, cover and thumbnail dimensions plus safe-zone guidance.
Use 1080×1350 for portrait social posts, 1080×1920 for full-screen vertical video and stories, and 1280×720 for YouTube thumbnails. Always check the platform's current upload guidance before a major campaign.
The quick reference
| Platform | Feed / post | Story / vertical | Thumbnail / cover |
|---|---|---|---|
| 1080×1350 (4:5) | 1080×1920 (9:16) | 1080×1080 profile | |
| TikTok | 1080×1920 (9:16) | 1080×1920 | Use a clear central safe zone |
| YouTube | 1280×720 thumbnail | 1080×1920 Shorts | 1280×720 |
| 1200×1200 or 1200×627 | — | 1584×396 banner | |
| 1080×1080 or 1200×630 | 1080×1920 | 851×315 cover | |
| 1000×1500 (2:3) | — | Keep text away from edges |
Dimensions are only half the job
A correct canvas can still produce a poor post if the platform crops the edges or covers the lower portion with interface controls. Keep the headline and product proof inside a central safe zone, especially for 9:16 video.
Export the right ratio first, then inspect the actual preview on a phone. Do not stretch a square creative into a vertical frame.
- Keep text large enough for a small screen.
- Leave breathing room near the top and bottom of full-screen video.
- Use one master concept, then adapt the composition for each ratio.
- Re-check current official specs when a platform changes its feed or profile UI.
