# twitter.text.max_graphemes

> Tweets cap at 280 graphemes — with t.co URL wrapping accounted for.

## What it checks

`countGraphemes(text) <= 280`, with URLs counted as 23 characters regardless of their real length (t.co wraps every URL).

## Why 280 + 23

Twitter's `tweet.create` enforces 280 graphemes. URLs are wrapped by t.co to a fixed 23-character length, so a 100-character URL still counts as 23. We subtract the real URL length and add 23 for each URL.

## Remediation

Trim the tweet, or break it into a thread.
