Short answer: for feed posts, 1080 × 1350 (portrait, 4:5) takes up the most room on Instagram and Facebook. Stories, Reels and TikTok use 1080 × 1920 (9:16). Link previews use 1200 × 630, and YouTube thumbnails 1280 × 720.
Platforms change their layouts from time to time. These sizes were last checked in September 2026, and they’re the same ones the Social Media Resizer uses.
| Image | Size (pixels) | Shape |
|---|---|---|
| Portrait post | 1080 × 1350 | 4:5 |
| Square post | 1080 × 1080 | 1:1 |
| Landscape post | 1080 × 566 | about 1.9:1 |
| Story or Reel | 1080 × 1920 | 9:16 |
| Profile photo | 320 × 320 | shown as a circle |
In Stories and Reels, keep text and faces away from the top and bottom 250 pixels or so, where the app puts its buttons and captions. Resize to a Story or a portrait post in one step.
| Image | Size (pixels) |
|---|---|
| Feed post | 1080 × 1350 |
| Link / shared image | 1200 × 630 |
| Page cover | 851 × 315 |
| Event cover | 1920 × 1005 |
| Story | 1080 × 1920 |
Phones crop the sides of a page cover, so keep the important part in the middle.
X (Twitter), LinkedIn and YouTube
| Platform | Image | Size (pixels) |
|---|---|---|
| X (Twitter) | Post image | 1600 × 900 |
| X (Twitter) | Square post | 1080 × 1080 |
| X (Twitter) | Header | 1500 × 500 |
| Post image | 1200 × 627 | |
| Square post | 1200 × 1200 | |
| Personal banner | 1584 × 396 | |
| Company banner | 1128 × 191 | |
| YouTube | Video thumbnail | 1280 × 720 |
| YouTube | Channel banner | 2560 × 1440 |
A YouTube thumbnail must be under 2 MB, so save it as JPG; the resizer can make one at 1280 × 720. Only the central 1546 × 423 of a channel banner shows on every device, so keep your name and logo inside that area.
Pinterest and TikTok
| Platform | Image | Size (pixels) |
|---|---|---|
| Standard pin | 1000 × 1500 | |
| TikTok | Video cover or photo | 1080 × 1920 |
Why upload at exactly these sizes?
Every platform resizes and re-compresses what you upload. If your image already has the right shape, nothing gets cropped where you don’t expect it. If it already has the right size, the platform has less resizing to do, so it stays sharper. The Social Media Resizer crops and resizes to each of these sizes in one step, and you choose what’s in the frame.
Posting a whole photo without cropping it
A landscape photo on Instagram gets either cropped or shown small. To keep all of it, add space around it instead: Add Border can pad a photo to 4:5 or 1:1 in any colour, so nothing is lost.
For a photo that’s too wide for one post, split it into a swipeable carousel with the Image Splitter: choose one row and as many columns as slides.
