How Many Characters in a Tweet?
A standard tweet allows 280 characters. This includes all text, spaces, punctuation, emojis, and special characters. Key things to know:
- URLs count as exactly 23 characters regardless of actual length (due to t.co link wrapping)
- Emojis count as 2 characters each
- Mentions (@username) count towards the limit
- Hashtags count towards the limit (including the # symbol)
X Premium subscribers can post up to 25,000 characters, effectively turning tweets into blog posts.
Tips for Staying Within Character Limits
- Write your message first, then edit down to fit the limit. It is easier to trim than to pad.
- Use our Social Media Character Counter to check your post length before publishing.
- Front-load your message. On Instagram and LinkedIn, only the first 1–2 lines show in the feed. Put your hook first.
- Thread it. On X, if your message is too long, break it into a thread rather than cramming it into one post.
- Use line breaks to create visual separation and improve readability, especially on LinkedIn and Instagram.
