- Emoji count as 2, even ones made of several characters, like flags and family emoji.

FAQ
Common questions
How does X count characters?
Standard accounts get 280. Most characters count as 1, but emoji and characters like Chinese, Japanese and Korean count as 2, and every link counts as 23 (X developer docs).
How long can posts be with X Premium?
Up to 25,000 characters (X developer changelog). Tick the Premium box to count against that.
How does the thread split work?
It breaks your text at paragraphs and sentences, then words if it has to, and adds 1/3, 2/3 and so on. Each post stays under 280.
Is anything I enter sent to you?
No. It runs in your browser, so nothing you type or upload reaches our servers.
