What are the limits?
- Title: 100 characters. Titles longer than this are cut off on upload.
- Description: 5,000 characters. The first 1–2 lines matter most, because that is what viewers see before clicking “more”.
- Search display: Titles are often truncated in search results at around 60–70 characters, so put the most important words first even if you stay under 100.
This checker counts characters only. It does not judge quality, and it does not send your text anywhere.
