Questions
What is the Instagram character limit?
Instagram captions can be up to 2,200 characters. Only about the first 125 show before the “more” link, so put the hook first.
What is the LinkedIn character limit?
LinkedIn posts allow 3,000 characters. Roughly the first 210 characters appear before “see more” on desktop.
What is the X (Twitter) character limit?
Standard X accounts get 280 characters per post; Premium accounts can post up to 25,000. Links always count as 23 characters.
What is the TikTok caption limit?
TikTok captions can be up to 4,000 characters, including hashtags.
Do emoji count as one character?
Most platforms count a visible emoji as one character, but X counts most emoji as two. This counter shows visible characters, so treat X results as approximate when you use emoji.
