Social media character limits explained
Every social platform has a different character limit — and many have two: the hard limit (maximum you can post) and the preview limit (what's visible without clicking "more"). Writing your most important content and call-to-action within the preview limit dramatically increases engagement.
| Platform | Hard limit | Feed preview |
|---|---|---|
| X / Twitter | 280 chars | No truncation |
| 2,200 chars | ~125 chars | |
| 3,000 chars | ~210 chars | |
| TikTok | 2,200 chars | ~100 chars |
| 500 chars | No truncation | |
| YouTube | 5,000 chars | ~157 chars |
| 63,206 chars | ~480 chars | |
| 40,000 chars | No truncation |
Write for the preview, not the limit
On Instagram, LinkedIn, and TikTok, only the first 100–210 characters show in the feed before the "more" button. Front-load your hook — the question, the bold claim, or the reason to keep reading — within the preview window. Save hashtags and tags for the end.
