What is the YouTube title character limit?
A YouTube title can be up to 100 characters. Spaces, punctuation, hashtags and emoji all count, and one emoji can count as more than one.
A title that fits can still be cut off on screen. Put the subject first, so the point survives wherever the title is shortened.

How I pack one carry-on for a weekend trip
58 remaining before Postdom's title limit.
The edit removes 76 counting units while keeping the carry-on bag, the one-bag constraint and the weekend trip. It does not change what the video promises. Both counts include spaces.
YouTube description character limit
Postdom has not verified a YouTube description maximum, so we don't quote one. That is a gap in our checked data, not a claim that descriptions are unlimited.
Postdom's own caption input accepts up to 4,000 characters. That is Postdom's limit, not YouTube's description allowance. Use YouTube's video settings help for the current editor rules.
Questions about the YouTube title character limit
What is the YouTube title character limit?
100 characters, including spaces and punctuation.
Do hashtags and emoji count in a YouTube title?
Yes. They are part of the title text. One emoji can count as more than one character.
Is the description limit the same as the title limit?
No. They are separate fields. Postdom has not verified a description maximum.
Where does my title come from with Postdom?
Through Postdom's MCP publishing tool, the first line of the caption becomes the title, so write that line as a complete title. An explicit title sent through the API must fit the limit, or Postdom's input check refuses it. Nothing posts until you approve it.

| Field | Limit and verification | What it means |
|---|---|---|
| YouTube title in Postdom | 100 UTF-16 code units | An explicit title must be nonempty and fit this limit. An overlong explicit title fails Postdom's input check; the MCP tool handles titles differently.Evidence reference: ARCHITECTURE.md#4-data-model |
| Postdom caption input | 4,000 UTF-16 code units | This is Postdom's shared caption field, not YouTube's description allowance. Passing this check does not guarantee YouTube acceptance.Evidence reference: ARCHITECTURE.md#4-data-model |
| YouTube description | Check YouTube's current guidanceNo verification date | Postdom has no separately verified description maximum here. That does not mean descriptions are unlimited or that YouTube publishes no limit. |
