How Long Can a Tweet Be? The 280 Rule, Counted Properly

The rule: 280 weighted characters, not 280 keystrokes

X caps a post at 280 weighted characters. Ordinary letters, numbers, spaces, and punctuation weigh 1 each. A URL of any length is rewritten through X's link shortener and weighs exactly 23 — a twelve-character link and a ninety-character tracking link cost the same. Most emoji weigh 2, and characters from Chinese, Japanese, and Korean scripts also generally weigh 2. Flags and some combined emoji sequences weigh more, because they are built from several underlying characters.

That weighting is why two drafts that look the same length can end differently. A post that is short in words but carries two links starts with 46 of its 280 already spent. A post with four emoji has spent 8 characters on decoration before a single letter lands. The limit did not change — the accounting did, and the accounting is invisible unless your tool shows it.

A thread is how X handles anything longer: a chain of individual posts, each within its own 280, shown together in order. A thread is not one long post with internal breaks; every link in the chain is counted and capped separately, which is why thread planning needs the count per post, not a total.

Worked example 1: the draft that fits — link and emoji included

Take this labeled example draft: 'Our spring menu is live — the full list, prices, and opening hours are on the site [link] ☕'. Count it the notes-app way and the raw text looks comfortably short. Count it X's way: the sentence itself is under ninety weighted characters, the link adds its flat 23, and the coffee emoji adds 2. The total lands well under 280. This draft fits with room to spare — room you could spend on one more specific detail, which is nearly always a better use of spare characters than a second emoji.

The lesson of the fitting example is that a link is not the budget-killer people fear. At 23 characters, one link costs less than a medium-length word cluster. Drafts usually overflow from words, not from the link they carry.

Worked example 2: the draft that secretly does not fit

Now a labeled example of the classic failure: a launch announcement drafted in a notes app at what the app reports as 274 characters — safely under, by its count. But the draft contains a long link and three emoji. X recounts: the link's raw length disappears and is replaced by 23, which actually helps — yet each emoji counts 2 instead of the 1 the notes app assumed, and a quoted phrase in another script counts double per character. The weighted total crosses 280, the composer refuses the post, and the author starts deleting words at random under time pressure.

This is the exact failure AutoTweet's free Twitter character counter exists to prevent. It counts the way X counts — links as 23, emoji as 2 — shows the weighted total and what remains as you type, and when a draft runs over, it splits the text into a clean numbered thread at sentence boundaries instead of leaving you to amputate the ending. Your wording is never rewritten; only the break points are chosen.

The pattern underneath both examples: never trust a count that does not know what a link costs. A general-purpose character counter is measuring a different platform's rules.

Why your notes app and word processor counts lie

Notes apps and word processors count raw characters — one per symbol, links at full length, emoji usually as one. Every one of those assumptions is wrong for X, and they push in opposite directions: a raw counter overstates a link-heavy draft (the link is cheaper than it looks) and understates an emoji- or CJK-heavy draft (those characters are dearer than they look). A draft can pass a raw count and fail the real one, or fail the raw count while fitting easily once the link is weighed at 23.

The only count worth trusting while drafting is a weighted one, checked before the post is queued — not discovered in the composer at posting time. Inside AutoTweet, every queued post is counted and fitted before its slot, which is what makes autopilot safe to leave running: the check the free counter does by hand is the same check the product applies to every scheduled post, thread, and link post automatically.

The exceptions: longer posts and what they change

X Premium accounts can publish posts longer than 280 characters. That is a paid feature of X itself, separate from any scheduling tool, and it changes the audience experience as well as the limit: longer posts are often shown folded, with the opening lines doing the work of earning the expansion. Most accounts, most of the time, are still writing for the standard limit — and a post that says its thing inside 280 rarely needs the extra room it is tempted by.

AutoTweet plans around the standard rule: Starter is free forever with manual scheduling and a 5-slot queue; Pro, $29/mo, posts 12 a day from a 500-post queue with autopilot; Creator, $49/mo, posts 24 a day from a 2,000-post queue. Whichever plan drafts or schedules your posts, the weighted count is checked the same way. If you write long-form on a Premium account, treat 280 as your opening-paragraph budget anyway — the part everyone sees should stand on its own.
