The Twitter Character Limit on X, Counted Properly
The Twitter character limit is 280 for most accounts, but URLs, emoji and non-Latin scripts are not counted one-for-one. Here is how the weighting works.
The Twitter character limit on X is 280 characters for standard accounts, but the count is weighted rather than literal: a URL counts as a fixed length however long it is, and characters in scripts such as Chinese, Japanese and Korean count as two. That is why a post can be rejected at what looks like 250 characters.
How the Twitter character limit is counted
| Content | Counted as |
|---|---|
| Latin letters, digits, punctuation | 1 each |
| CJK and some other scripts | 2 each |
| A URL of any length | A fixed length, set by X's link wrapper |
| Emoji | Often 2, sometimes more for composed emoji |
| An attached image or video | 0 — attachments do not consume characters |
The URL rule is the useful one. Shortening a link before posting saves you nothing, because X substitutes its own wrapper and charges the same either way. Use the real URL, which is also more trustworthy to a reader.

The practical limit is lower than the real one
Two reasons to aim well under 280.
Quoting. A post that someone can quote and add a line to travels further than one that fills the space. Leaving room is a distribution decision.
Reading. Short posts are read; long ones are skimmed. Empirically, the posts that travel furthest on X are considerably shorter than the limit.
If your point genuinely needs more space, that is a thread rather than a longer post — how to write a Twitter thread.

Premium accounts on X can post far longer text, which sounds like it removes the constraint. In practice it moves it: long posts are collapsed behind a "Show more" link in the timeline, so the first couple of lines are still doing the entire job.
That is the same structural problem as Instagram caption length and where LinkedIn puts See more — a fold rather than a cap, and folds are unforgiving in a scrolling feed.
What the limit does not include
Attachments are free. An image, a video, a poll or a quoted post costs no characters, which makes them the cheapest way to add substance to a post that is already full.
Images have their own constraint — the timeline crop, which is more aggressive than people expect:

Threads allows 500 characters and chains overflow into a second post rather than refusing it — the Threads character limit. Anyone crossposting should write to the tighter limit, which is X's; the full comparison is in how to post on X and Threads.
How many characters is a tweet?
280 for standard accounts, counted with weighting. Premium accounts can post considerably longer text, which is collapsed behind a "Show more" link.
Do links count toward the character limit?
Yes, but as a fixed length regardless of the URL's actual length - so shortening a link saves nothing.
Do emoji count as one character?
Usually two, and sometimes more for composed emoji such as those with skin-tone modifiers.
Do images count toward the limit?
No. Images, videos, polls and quoted posts are free.
Count it the way X does, across every platform at once: character counter.
