Instagram character counter

2,200 characters. This counter counts the way Selfpost does when it posts for you, so most emoji count as two characters. Keep your point in the first line, since that's what people see before they tap more.

Up to 5 on a post or reel. Instagram's help center says a post with more than 5 hashtags won't go out. Pick the five that name your topic best; specific tags like #sourdoughbaking help more than broad ones like #food.

Up to 20 @mentions per caption. The counter finds every @name that starts a word, so an email address doesn't count as a mention.

TikTok accepts 2,200 characters for captions sent through its official posting interface, which is what apps like Selfpost use. Hashtags and @mentions count toward that number.

A title can have up to 100 characters. A description can have up to 5,000 bytes: a plain letter is one byte, a letter like ä is two and most emoji are four, so a description full of emoji fits fewer characters. Neither may contain < or >. Up to three hashtags appear next to your title, and a video with more than 60 hashtags has all of them ignored.

A marked hashtag appears more than once. #Berlin and #berlin count as the same tag, so one of them is enough and the space is better spent on another word.

No. The counter runs in your browser. Nothing you type leaves your device, and it's gone when you close the tab.
