The limit that matters is the visible one
Most platforms cut text visually long before the hard limit: Instagram shows ~125 caption characters before "more", LinkedIn ~210, Facebook ~477, and YouTube search truncates titles near 70. Write to the visible limit — hook first, context after the fold — and treat the hard cap as space for hashtags, credits, and keywords rather than the message itself.
Frequently asked questions
What is the Instagram caption character limit?+
2,200 characters — but only about the first 125 show in the feed before the “more” cutoff, so front-load your hook. Bios are capped at 150 characters and usernames at 30.
What is the character limit on X (Twitter)?+
280 characters for standard accounts. X Premium subscribers can post up to 25,000 characters, though only the first 280 show in the timeline before expansion.
How long can a TikTok caption be?+
4,000 characters — TikTok expanded it from 2,200 to make room for keyword-rich descriptions, which now matter for TikTok search ranking. Bios remain short at 80 characters.
How long can an Instagram story be?+
Up to 60 seconds per story card. If you upload a longer video, Instagram automatically splits it into consecutive 60-second segments. Stories disappear after 24 hours as usual.
How long can a TikTok video be?+
Up to 10 minutes when recording in-app, and eligible accounts can upload videos up to 60 minutes. TikTok Stories are capped at 15 seconds. For monetization, remember only videos over 1 minute earn Creator Rewards.
What is the YouTube title character limit?+
100 characters, but search results typically truncate around 70 — keep the essential keywords in the first 60-70 characters. Descriptions allow 5,000 characters and total tags 500.
Does this counter count emoji correctly?+
The counter uses the same character counting as most platforms (UTF-16 code units), so standard emoji count as 2 characters — matching what Instagram and X actually enforce. When in doubt near a limit, leave a few characters of buffer.
