Your Instagram caption gets cut at 125 characters

Paste a caption above and the counter measures it against Instagram's 2,200-character limit while marking the point where the feed collapses it. Nothing uploads anywhere, the count runs in your browser as you type.

The same box counts your draft for the other nine platforms at once, which is the fastest way to find out whether an Instagram caption will survive a trip to X or Threads.

Instagram allows 2,200 characters in a caption, which sounds generous until you look at what the feed actually renders. Roughly the first 125 characters appear before the more link, and on a phone that is about two lines. Everything past that point is only read by people who already decided to tap.

That changes how the opening gets written. Put the hook, the promise, or the question inside the first 125 characters and treat the rest as the payoff for people who tapped through. Opening with a string of @mentions or hashtags burns visible characters on text that does nothing to earn the tap.

Hashtags have their own ceiling. Instagram rejects captions carrying more than 30 hashtags, and the counter tracks your count against that cap as you type. Most accounts do better with three to five specific tags than with thirty broad ones, because the broad tags place you in feeds where nobody is looking for your niche in the first place.

Two other limits get confused with the caption limit. Your Instagram bio is a separate 150 characters, and the first comment is its own 2,200-character field, which is where plenty of accounts park a hashtag block to keep the caption itself readable.
