Platform specs drift over time, but teams still need a stable production baseline. These sizes are practical starting points for publishing and resizing workflows in 2026.
| Asset | Recommended size | Workflow note |
|---|---|---|
| Instagram post | 1080 x 1080 | Use square as the safest default |
| Instagram portrait | 1080 x 1350 | Best for feed presence |
| Facebook shared image | 1200 x 630 | Common link-share ratio |
| X image | 1200 x 675 | Good default for social previews |
| LinkedIn shared image | 1200 x 627 | Keep text clear and centered |
| YouTube thumbnail | 1280 x 720 | High contrast works best |
Publishing tips
- Keep text away from the edges where crops vary by device.
- Prepare one master size per platform, then export campaign variants from that base.
- Review thumbnails and feed previews on mobile before final scheduling.
- Use lighter compression for fast-loading ad creatives, higher clarity for detail-rich posts.
