Aspect Ratios to Use for LinkedIn Posts
Aspect ratio is the shape of the image, and the wrong one leads to awkward crops. Professional feeds load on slow office Wi-Fi and phones alike, so a compact image keeps your post readable on every connection.
Recommended settings for LinkedIn posts
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1200 px on the long edge |
| Quality | 78 |
| File size | 400 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Aspect Ratios to Use
Common ratios are 1:1 square, 4:5 portrait, 3:2 classic photo and 16:9 widescreen. Pick the one that matches where the image will be displayed for LinkedIn posts.
Crop to the ratio first, then resize to about 1200 pixels on the long edge and compress. Cropping last can undo your careful sizing.
