Frequently asked questions
How does X count characters in a post?
X uses weighted counting. Most Latin letters, numbers and punctuation count as 1. Emoji and Chinese, Japanese and Korean characters count as 2. Every link counts as 23, however long it is. A standard post can weigh up to 280.
Why does my link count as 23 characters?
X shortens every link with its t.co service, so each URL takes a fixed 23 characters no matter how long or short the original is.
Does the X character limit include spaces?
Yes. Spaces and line breaks each count as 1 toward the 280 limit, the same as a letter. This counter includes them.
How long can an X bio be?
Up to 160 characters, according to the X Help Center.
Will this count always match the X app?
It follows the published twitter-text v3 weights. Links starting with http, https or www are always found; bare domains are found for common endings such as .com, .net and .org. The X composer stays the final check.
