Why do character limits matter?
Every platform cuts your text at a fixed length. A tweet stops at 280 characters, an Instagram bio at 150, and a YouTube title at 100. If your text is too long, the platform shortens it for you — usually in the worst place. This counter shows your length against the real limits while you write, so you stay in control.
How to use it
- Type or paste the text you plan to post.
- Watch the bars for each platform. Green room to spare, red means over the limit.
- Trim your text until every platform you care about fits.
Frequently asked questions
Do spaces count as characters?
On almost every platform, yes. That is why this tool shows the count both ways.
Are these the real platform limits?
Yes — X post 280, Instagram bio 150, Instagram caption 2,200, LinkedIn post 3,000, YouTube title 100, and about 155 characters for a Google meta description before it is usually cut off.
