Counted in characters as you see them. X counts links and some emoji differently.

The limit is not the target

Every platform shows only the first line or two of a caption before cutting it off, so the opening has to earn the tap. Write the first line as if it were the only one, put the one action you want near the end, and use the rest of the room only if the reader gains something from it.

PlanMedia's Copywriter works to that structure: a first line that earns the second, a middle that tells the reader something new, and a close that asks for one clear action, in the brand's own voice and languages.

Questions people ask

How long can an Instagram caption be?

Up to 2,200 characters. Only the opening shows before the caption is cut, so put the point in the first line.

What is the character limit on X?

280 characters for a standard account. X counts links and some emoji differently from what you see.

Do hashtags count towards the limit?

Yes. Hashtags and mentions are part of the caption and count as characters.
