# YouTube description counter

Canonical: https://postmesh.app/tools/youtube-description-character-counter

YouTube allows 5,000 bytes in a description. Paste yours to see what’s left, and how the same text fares on the other networks.

## How it works

The count uses the same rule PostMesh checks before it posts to YouTube: 5,000 bytes. The limit is in bytes: English letters are one byte each, accented letters two and most emoji four.

Below the YouTube count, the same text is checked for every network PostMesh publishes to, so you can see where it needs to be shorter before you post it everywhere.

Nothing you type leaves your browser.

## Steps

1. Type or paste your description.

2. Read the YouTube count and what’s left.

3. Check the other networks if you’ll post it there too.

## Every YouTube limit PostMesh checks

These are the rules PostMesh runs before it publishes, one row per post type. The source and the date each was last checked live in PostMesh’s publishing rules.

| Post type | Text | Title | Hashtags |
| --- | --- | --- | --- |
| Video upload | 5,000 bytes (description) | 100 characters | No cap |
| Short | 5,000 bytes (description) | 100 characters | No cap |

## Ways to fit a post that runs over

- Cut the opening line to the point: it’s the part people see before “more”.
- Move links to your bio or a first comment where the network allows it.
- Swap a long phrase for a shorter one rather than dropping hashtags you need.
- Write a short version for the strictest network, then add detail where there’s room.
