LinkedIn character limits and posting rules

Last reviewed: 29 August 2026

3,000 characters per post. LinkedIn no longer accepts .MOV video uploads.

What are LinkedIn's limits at a glance?

The table gives the figure Postey applies for LinkedIn, the field it applies to, the unit it is counted in, and whether LinkedIn enforces it when a post is published.

Field	Maximum	Counted in	Enforced at publish?
post	3,000	Code points	Yes, at publish time

How long can a LinkedIn post be?

LinkedIn caps a post at 3,000 characters, and Postey checks a draft against that cap before it publishes.

How does LinkedIn count a character?

LinkedIn counts code points, which is the unit Python’s len() returns on Postey’s backend, so the count you see in Postey is the count LinkedIn applies.

What media rules apply to a LinkedIn post?

LinkedIn applies one media rule Postey enforces before it publishes.

No longer accepts .MOV video uploads.

What happens to a LinkedIn draft that is over the limit?

Postey refuses the draft and names the post limit it broke. LinkedIn does not thread, so a long draft stays one post or it does not go out.

How does LinkedIn compare with the other platforms?

Postey publishes the same draft to every platform below, reshaping it against each one's own limit rather than against LinkedIn's.

X	post	280 characters	Weighted (link 23, emoji 2)	Yes, at publish time
Threads	post	500 characters	Code points	Yes, at publish time
