Instagram Caption Limit in 2026 (And the 125 That Matter)
TL;DR
The Instagram caption limit is 2,200 characters, but only the first 125 show before 'more'. Every caption and bio limit, and how to write for the cut-off.
Instagram allows 2,200 characters in a caption and shows about 125 of them. The rest sits behind "more". So the limit that governs your writing is the opening line, not the one in the docs: that line decides whether anyone taps. Here are all the numbers, and what to do with the one that matters.
Instagram Text Limits
| Where | Limit |
|---|---|
| Caption | 2,200 characters |
| Visible before "more" | about 125 characters |
| Hashtags per post | 30 (counted inside the 2,200) |
| Bio | 150 characters |
| Username | 30 characters |
The First 125 Characters Do the Work
In the feed, a caption is a teaser. About 125 characters show, then it's truncated. That's a short sentence, maybe two. Everything you want a casual scroller to know has to fit there.
- Open with the point, not a preamble. "Three things I got wrong about..." beats "So I've been thinking lately about...".
- Skip the greeting. "Hey everyone!" costs you a tenth of the visible space.
- Ask or promise something. A question or a specific claim gives a reason to expand.
- Put hashtags last. They belong after the caption, or in the first comment, so they don't consume the preview.
Instagram Also Requires Media
One limit that isn't about characters: Instagram has no text-only posts. Every post needs at least one image or video, and that's a platform rule rather than a scheduler one. If you're publishing through an API and a post fails with a media error, this is usually why. Sizes for that media are in Instagram post size and dimensions.
FAQ

How many hashtags can I use?
Up to 30 per post, and they count toward the same 2,200-character caption limit.
