Question 1

What is the Twitter / X character limit?

Accepted Answer

Free X (formerly Twitter) accounts have a 280-character limit per post. X Premium subscribers can write posts up to 25,000 characters. URLs always count as 23 characters regardless of actual length.

Question 2

How are Twitter threads created?

Accepted Answer

On X, a thread is a series of connected posts. Type your first tweet, click 'Add Post' to add the next one, and keep writing. Each post can be 280 characters, and the entire thread is published as one composition.

Question 3

Do URLs count as 23 characters on X?

Accepted Answer

Yes. X (Twitter) automatically shortens links with t.co. All URLs in a post count as exactly 23 characters, no matter how long the original URL is. This tool applies the same 23-character URL rule to its counter.

Question 4

Does this tool support X Premium long posts?

Accepted Answer

Yes. You can switch between Free (280 chars) and Premium (25,000 chars) modes. The character counter updates to reflect the active limit and shows a warning color when you approach or exceed it.
