Guía

Twitter / X Character Counter

Write and count your tweet with Twitter’s exact character counting rules. This tool applies the same algorithm Twitter/X uses — URLs always count as 23 characters regardless of length, and emoji have weighted counts. Real-time feedback shows remaining characters with color-coded warnings, and thread mode splits long content into multiple tweets automatically.

Cómo utilizar

Type or paste your tweet text in the input area. The counter updates in real time, showing characters used and remaining out of the 280 limit. URLs are highlighted and counted as 23 characters each. When you go over the limit, the counter turns red and thread mode activates to split your content.

 Preguntas frecuentes

Why do URLs count as 23 characters on Twitter?

Twitter automatically wraps all URLs using their t.co URL shortener, which produces links of a fixed length (currently 23 characters). This means a short URL like example.com and a long URL like https://example.com/very/long/path?with=query&params=here both count as exactly 23 characters toward your 280-character limit. Twitter does this to protect against URL manipulation and to enable link tracking, so you can always use full descriptive URLs without wasting extra characters.
Why do some emoji count as 2 characters?

Twitter uses Unicode code points to count characters, and many emoji are represented by Unicode characters outside the Basic Multilingual Plane (BMP). Characters in the supplementary planes (code points above U+FFFF) are encoded as two UTF-16 code units called surrogate pairs, and Twitter counts each surrogate pair as 2 characters. Standard ASCII characters count as 1. Most modern emoji (especially those added after 2010) fall into this category, so a single emoji like 🔥 or 🎉 typically costs 2 of your 280 characters.
How does Twitter thread mode work?

A Twitter/X thread is a series of connected tweets posted in reply to each other. When your content exceeds 280 characters, you can split it into a thread where each tweet is numbered (1/3, 2/3, 3/3). The thread composer in this tool automatically divides your text at the 280-character boundary, accounting for the tweet number label. Each tweet in a thread has the same 280-character limit, and the numbering itself counts toward those characters.
