Best 3 Tweet Character Counter Tools Compared
Heshan Fernando
Co-founder & COO
You’re drafting a post for X and want to know the exact character count before hitting publish — accounting for the platform’s weighted rules where URLs always count as 23 characters and emoji cost double, not a naive length check.
Every counter here applies X’s weighted counting; the differences are in whether the tool uses the same official counting library X itself enforces, whether it handles threads or other surfaces (bios, DMs), and whether Premium’s higher character limit is supported.
How to judge a tweet character counter tool
Uses X’s actual weighted counting rules, not a simple character tally. URLs always count as exactly 23 characters regardless of actual length, most emoji count as 2, and CJK (Chinese, Japanese, Korean) characters count as 2 — a naive .length check gets this wrong.
Ideally runs the same library X enforces, not an approximation. A counter that states it’s built on the actual twitter-text library gives you confidence the number shown will match what X actually enforces at publish time.
Supports the surface you’re actually composing for. Posts (280 or Premium’s higher limit), bios (160), display names (50), and DMs each have different limits — a tool scoped to just posts won’t help for a bio.
Processes text locally. Draft posts are often unpublished and sometimes sensitive — client-side counting with nothing uploaded is the safer default.
The comparison
| Tool | Best for | Free tier | Watch out |
|---|---|---|---|
| Typefully | Automatic thread splitting when text exceeds the limit | Free, no signup | Thread-splitting feature may be more than a quick single-post check needs |
| Pallyy | Simple, precise official-library count with clear visual warning bar | Free, no signup, client-side | Fewer extra features (threads, multi-surface) than Typefully or Postiz |
| Postiz | Multiple X surfaces covered (posts, bios, DMs, display names, handles) | Free, no signup, client-side | More surface options than a single quick post-length check needs |
| Tweet Character Counter | Post character count using X’s weighted rules | Free, no signup | Post-length checking only, no bio/DM/thread support |

Typefully
Typefully runs on the same weighted-counting library its own composer uses when scheduling a real post, accounting for links (23 characters), emoji (2 characters), and CJK text (double weight), with a Premium toggle to check against either the 280 or 25,000 character limit, and automatically splits over-limit text into a numbered thread breaking at paragraph and sentence boundaries — completely free with no login.
It isn’t for someone who just wants a bare single-post count — the automatic thread-splitting is a genuine strength but adds functionality beyond a quick length check.
Pallyy
Pallyy counts entirely in your browser using the official twitter-text library so the count matches exactly what X enforces, applying the same weighted rules (URLs at 23, emoji doubled, CJK doubled) with a live visual bar that turns amber inside the last 20 characters and red once over the limit, with nothing uploaded or saved.
It isn’t for someone who needs multiple X surfaces covered — it’s focused specifically on the 280-character post limit rather than bios, DMs, or other surfaces.
Postiz
Postiz tracks character counts in real time across multiple X surfaces — posts (280 free / up to 4,000 Premium longposts), bios (160), display names (50), handles (15), and DMs (10,000) — applying the same weighted rules for URLs, CJK characters, and emoji, adapting the displayed limit based on which surface you select.
It isn’t for someone who just wants a fast single-post check — switching between surface types is useful breadth but more than a straightforward tweet-length check needs.
Tweet Character Counter
Our tool counts post characters using X’s weighted rules — URLs count as 23 characters and wide characters count double — entirely in your browser.
A real limitation: it checks post length only — for bios, DMs, display names, or automatic thread splitting, Postiz or Typefully cover those additional surfaces and features.
Which one to pick
If you just want a fast, accurate single-post character check, use our Tweet Character Counter or Pallyy.
If your draft might exceed the limit and you want it auto-split into a thread, use Typefully.
If you’re checking limits across multiple X surfaces (bio, DM, display name), use Postiz.
If you want the simplest possible interface with a clear visual warning bar, use Pallyy.

Frequently asked questions
Is there a free tweet character counter that doesn’t need an account?
Yes. Our Tweet Character Counter and all three alternatives here count characters without requiring signup.
Why does a URL always count as exactly 23 characters on X, regardless of its actual length?
X automatically wraps every link in a t.co shortener for tracking and security purposes, and that wrapped version has a fixed length — so whether you paste a short URL or an extremely long one with tracking parameters, it counts identically toward your character limit. This is documented behavior, not a bug, and it’s exactly why a naive character counter that doesn’t know about this rule will give you the wrong number.
Why do emoji and CJK characters count as two characters instead of one?
X’s counting system is based on Unicode code point weighting, where characters outside the basic Latin range — including most emoji and CJK (Chinese, Japanese, Korean) characters — are weighted as two units rather than one, reflecting their typical display width and encoding complexity. This is defined in X’s twitter-text library specification, which is the actual counting logic the platform enforces.
Final thought
Don’t trust a plain .length character count for X — links, emoji, and CJK text all count differently than their literal character length, and a counter built on X’s actual weighted rules is the only way to know your post will fit before you publish.
