X (Twitter) character counter
Count characters in your tweet with real-time feedback. Supports threads and media character deductions.
about the x (twitter) character counter
X (formerly Twitter) limits standard posts to 280 characters, and going over means your tweet won't send. This free character counter shows your count in real time as you type, so you know exactly where you stand before you post — no guessing, no rejected tweets.
Counting is smarter than a raw character tally. Links always count as 23 characters on X regardless of their actual length, and attaching media reserves characters too. This tool accounts for those rules so the number you see matches what X will actually count.
Writing a thread? Paste your full text and the counter helps you find natural break points that keep each tweet under the limit. When you're ready to schedule the whole thread and post it automatically, PostAI takes it from there.
frequently asked questions
What is the X (Twitter) character limit?
Standard X posts are limited to 280 characters. X Premium subscribers can post up to 25,000 characters, but the 280-character limit applies to the visible preview and to all non-Premium accounts.
Do links count toward the Twitter character limit?
Yes. Every link counts as 23 characters on X, no matter how long or short the actual URL is, because X wraps links in its t.co shortener. This counter accounts for that automatically.
How many characters is a Twitter thread?
Each post in a thread can be up to 280 characters. There's no limit on the number of posts in a thread, so threads are the standard way to share longer content on X.
