About these limits
Limits were last checked in September 2026. Platforms change them without much notice, so if a post won't publish, check the app. Instagram has been rolling out a limit of 5 hashtags per post since December 2025. TikTok allows longer captions in its app than through scheduling tools, so this checker uses the safer 2,200.
Apps count some characters differently. Emoji can count as more than one, and X counts links as 23 characters. Treat a caption that's right at the limit as over it.
