How it works
Social Media Character Counter in three steps
Write your post
Type or paste a caption, tweet, or description in the box.
Check every platform
See how much room you have left for each network at the same time.
Trim and publish
Edit until you fit, then copy your post wherever it needs to go.
One post, every platform limit
Each social network counts characters differently and caps posts at a different length. This counter shows your text against all of them at once, so you can write a single caption and instantly see where it fits and where it needs trimming.
Limits it tracks
- X / Twitter — 280
- Bluesky — 300
- Threads & Mastodon — 500
- Instagram & TikTok captions — 2,200
- LinkedIn post — 3,000
- YouTube title — 100 · description — 5,000
Made for creators and social teams
Whether you are repurposing one idea across networks or fitting a hook into a tight title, seeing the remaining count update as you type saves the back-and-forth of posting, getting cut off, and editing. The counter runs entirely in your browser, so drafts stay private until you publish them. Turning a video or podcast into captions and posts? Transcribe it with SozAI first, then shape the highlights here.

Frequently Asked Questions
Which platforms does it cover?
X/Twitter, Bluesky, Threads, Mastodon, Instagram, TikTok, LinkedIn, and YouTube titles and descriptions, with their current character limits.
Does the count update as I type?
Yes. Character counts and remaining room for every platform update live with each keystroke.
What happens when I go over a limit?
The card for that platform turns red and shows how many characters you are over, so you know exactly how much to cut.
Does it count emojis and links?
It counts every character you type, including emojis and full link text. Note that some platforms shorten links when posted.
Is my text saved or uploaded?
No. Everything runs in your browser. Your draft is never uploaded or stored.
