This free YouTube character counter checks your title against YouTube's 100-character limit and your description against 5,000, before you upload. The switch next to the count flips between them.
It shows every other platform beside them, so you can see where else the same words fit.
Here are YouTube's limits, and how to write a YouTube title and description.
YouTube's character limits
| Text | Limit | How it counts |
|---|---|---|
 YouTube title | 100 | Characters you see |
| YouTube description | 5,000 | Characters you see |
The limits come from YouTube Help: the title limit and the description limit.
Writing a YouTube title
- Say what the video gives: a clear promise beats a clever one.
- Put the main words first: long titles get cut short in some places, so the start matters most.
- Stay well under 100: the limit is a ceiling, not a target.
Writing a YouTube description
- Open with 1 or 2 lines on what the video covers: that's what shows before "more".
- Add chapters and links below: 5,000 characters leaves plenty of room.
Post it everywhere
The counter above checks the same post on every platform at once, and each has its own page too: X, LinkedIn, Threads, Bluesky, Mastodon, Instagram, TikTok and Pinterest.
When it's ready, turn it into an image for the feeds that want one with my post image generator, and schedule it with the tools on my creator tools page.
