How each platform counts it
Every platform but one counts by character: type an emoji, get charged for one character, same as a letter. X is the exception. It rewrites any link to a short one and always charges 23 characters for it, and it charges most emoji 2 characters instead of 1.

Questions
What's the TikTok caption character limit?
TikTok allows up to 2,200 characters in a caption.
How long can an Instagram Reels caption be?
Up to 2,200 characters, and the same limit applies to a first comment.
What's the caption limit on X?
280 characters, but X counts them its own way: a link always costs 23 characters, however long the URL is, and most emoji cost 2. Two captions with the same number of letters can use very different amounts of that limit.
How long can a Threads post be?
Up to 500 characters, the same limit a first comment gets.
What's Bluesky's character limit?
Up to 300 characters, counted the same way as everywhere but X: by character, so an emoji still counts as one.
Does a YouTube Shorts caption have one limit or two?
Two: a title up to 100 characters and a description up to 5,000. If you only write one caption and no separate title, Deploy uses the first 100 characters of it as the title and the whole caption as the description.
Write it once, post it everywhere
Deploy checks a caption against every one of these limits automatically, then posts it to whichever destinations you pick. Free for five videos a month.
