Definition: A character limit is the maximum number of characters a platform accepts in a post, caption or field, including spaces, emojis and links.
Updated October 10, 2026
Spaces and line breaks count. Most emojis count as two characters on X. Links on X always count as 23 characters, whatever their length. The visible preview is much shorter than the limit: people see roughly the first 125 characters of an Instagram caption and the first 210 of a LinkedIn post before “see more”.
| Platform | Post or caption limit |
|---|---|
| X (standard account) | 280 |
| Bluesky | 300 |
| Threads | 500 |
| Pinterest (description) | 500 |
| Instagram caption | 2,200 |
| LinkedIn post | 3,000 |
| TikTok caption | 4,000 |
| YouTube description | 5,000 |
| Facebook post | 63,206 |
A 1,400-character LinkedIn post fits as is, but needs cutting to under 300 for Bluesky and 280 for X. Writing a separate short version beats truncating the long one.
Cross-posting is publishing the same piece of content to more than one social network, either unchanged or adapted for each one.
Content repurposing is turning one piece of content, such as a blog post, video or talk, into several new pieces in different formats for different platforms.
Write once, tailor each version yourself or with optional AI, and schedule to 6 networks from one calendar.
