Instagram character limit
The Instagram profile bio limit is 150 characters, according to Add a bio to your Instagram profile, Instagram Help Center, checked on 23 July 2026. Two fields dominate the searches: the 150-character bio, which is the tightest field most people write in regularly, and the 2,200-character caption.
Count your text against this limit
Counted in characters, the unit Instagram actually uses, not in plain characters. Nothing you type here leaves your browser.

What happens when you go over
The field stops accepting input. On the bio this is easy to miss on mobile, because the keyboard covers the counter.
Line breaks count against the bio limit like any other character, which is why a four-line bio with blank lines between them runs out of room sooner than the character count suggests.
Every Instagram limit, with its unit
| Field | Limit | Counted in | What people get wrong |
|---|---|---|---|
| Profile bio | 150 | characters | The tightest field most people write in regularly, and the one where line breaks quietly eat your budget. |
| Caption | 2,200 | characters | Meta documents 2,200 for Instagram ad captions, together with a maximum of 30 hashtags per caption. Only the first two lines or so are shown before the More link. |

Does Instagram count emoji differently?
Instagram publishes its limit in plain characters, so an emoji costs the same as a letter in the field itself. How the emoji is stored underneath can still differ: see the methodology page for the four ways WordBench measures the same text.
Where does this number come from?

Do line breaks count in an Instagram bio?
Yes. A line break counts against the bio limit of 150 characters like any other character, which is why a four-line bio with blank lines between them runs out of room sooner than the character count suggests.
How much of an Instagram caption shows before the More link?
Only the first two lines or so, whatever the caption's length. Everything after that, up to the limit of 2,200 characters, sits behind the More link, so the opening line has to carry the post.
