Whether you are writing a tweet, an SMS or a meta description, staying under the limit matters. This character counter updates live as you type and flags common limits.
It runs in your browser and nothing you type is stored or uploaded.
How to use the Character Counter
- Paste or type your text.
- Watch the character count update live.
- Stay within the limit for your platform.
Character limits that actually matter
Almost every platform enforces a hard character limit, and going over it either cuts your text or blocks the post. These are the limits people check most often:
| Platform / field | Limit |
|---|---|
| X (Twitter) post | 280 characters |
| Instagram caption | 2,200 characters |
| Instagram bio | 150 characters |
| TikTok caption | 2,200 characters |
| YouTube title | 100 characters |
| LinkedIn post | 3,000 characters |
| SMS (single message) | 160 characters |
| Google title tag (SEO) | about 60 characters |
| Google meta description | about 160 characters |
Characters with and without spaces
Most platform limits count every character including spaces, which is what this counter shows by default. Some academic and professional requirements count characters without spaces instead, so both numbers are displayed live as you type. One thing to watch: emoji and some special symbols can count as two characters on certain platforms, so leave a little margin when a post sits exactly at the limit.
Common uses
- Writing posts and bios that fit exactly within social media limits
- Keeping SEO titles and meta descriptions inside Google's display length
