How many characters can an Instagram post caption contain?

Question

Cifra · Accepted Answer

2,200 characters. An Instagram caption can run up to 2,200 characters, though the app truncates it after the first few lines with a "more" link unless the reader taps to expand it. Very few captions actually approach the limit — most posts use only a fraction of the space available. Compare it to the platforms built around text. A microblogging service caps posts at a few hundred characters; a platform built around images needs enough room for a caption that can occasionally be an essay, but no reason to allow a full article. That places the limit an order of magnitude above the microblogging figure, which is exactly where it sits. The truncation point matters more than the limit, exactly as it does for video titles. The app cuts a caption after a couple of lines and hides the rest behind a tap, so the effective length for most readers is a fraction of what is permitted. Any platform limit should be read alongside how much of it is actually displayed. The behavioural note in the explanation is the honest one: almost nobody comes close. A generous limit is not a target, and on an image-led platform the caption is supporting text rather than the content. Published platform limits change without announcement, so a figure like this is a snapshot of documentation at a point in time rather than a stable property of the service.
