The short answer
A LinkedIn post can be up to 3,000 characters; for anything longer, an article can run to 125,000. You can share up to 20 images in a post. A video can be up to 15 minutes and 5 GB, in any shape from 1:2.4 (tall) to 2.4:1 (wide), at 10 to 60 frames a second, from 256 × 144 up to 4096 × 2304.
Videos posted from a LinkedIn Page or Career Page have a shorter limit of 10 minutes. These figures come from LinkedIn’s Help Centre.

Writing within 3,000 characters
3,000 characters is around 450 to 500 words, plenty for a post. The constraint that matters more is the first few lines: LinkedIn shows the start of a post and hides the rest behind “see more”, and how long people spend reading is part of how the feed ranks it. Put the point in the opening line, so the people who stop know why they should keep reading.
For longer pieces, LinkedIn articles allow 125,000 characters, with headings and images. A post that links to your own article keeps the reader on LinkedIn.
Images
A post can carry up to 20 images, which LinkedIn lets you crop, straighten and filter as you add them, and each can have alternative text for people using screen readers. On a phone, a vertical or square image takes more of the feed than a wide one; keep any text in the image large enough to read at that size.
Video
LinkedIn accepts almost any shape, from 1:2.4 to 2.4:1, so vertical, square and wide video all work. For the feed on a phone, vertical or square fills more of the screen. Export at 1080 pixels on the short side or more, at 30 frames a second, and keep the file under 5 GB.
Length depends on who posts. A personal profile can post videos up to 15 minutes; a LinkedIn Page or Career Page is limited to 10. Every video must be at least 3 seconds and 75 KB.
| Limit | Personal profile | LinkedIn Page or Career Page |
|---|---|---|
| Longest video | 15 minutes | 10 minutes |
| Shortest video | 3 seconds | 3 seconds |
| File size | 75 KB to 5 GB | 75 KB to 5 GB |
| Shape | 1:2.4 to 2.4:1 | 1:2.4 to 2.4:1 |
