Twitter Character Counter

What this Twitter character counter does

This free Twitter character counter shows you exactly how long your tweet is as you type it, measured the same way X (formerly Twitter) measures it. Paste a draft or write straight into the box, and the live count, the remaining characters, and a circular progress ring update on every keystroke. The moment you cross the limit, the counter turns red and tells you precisely how many characters you need to cut. There is nothing to install and no account to create — it all runs instantly in your browser.

What sets this tweet character counter apart from a plain word counter is that it follows X's real counting rules. Links are scored at a fixed 23 characters under the t.co rule, emojis and CJK (Japanese, Korean, Chinese) characters count as two each, and the tool supports both the standard 280-character limit and the 25,000-character X Premium limit through a single toggle. If your post is too long for one tweet, the built-in thread splitter turns it into a clean, numbered thread in one click.

How to use the tweet character counter

1. Type or paste your tweet. The character count, words, lines, and link count update live as you write.
2. Pick your limit. Use the toggle to switch between Free (280) for standard accounts and Premium (25,000) for X Premium long-form posts.
3. Watch the ring. The progress ring stays green with room to spare, turns amber as you approach the limit, and goes red the instant you go over.
4. Check the link note. If your tweet contains a URL, the tool flags that it counts as 23 characters so the total matches what X will actually post.
5. Copy or split. Copy the finished tweet with one click, or hit Split into thread to break a long draft into numbered 280-character tweets you can copy one by one.

Twitter / X character limits explained

Standard X accounts are capped at 280 characters per tweet — double the original 140-character limit the platform launched with. X Premium (the paid subscription formerly called Twitter Blue) raises that ceiling dramatically to 25,000 characters, enabling long-form posts, essays, and articles published natively in the timeline. This counter handles both: the Free mode counts against 280, and the Premium mode counts against 25,000, so you can plan content for either tier accurately.

• Standard tweet: 280 characters, including spaces, punctuation, hashtags, and mentions.
• X Premium long-form: up to 25,000 characters for subscribers.
• Direct messages: up to 10,000 characters, far more than a public tweet.
• Display name: 50 characters; bio: 160 characters.

The 23-character link rule

One of the most misunderstood parts of counting tweets is how links are measured. X runs every URL you post through its own link shortener, t.co, and the shortened version always occupies exactly 23 characters — whether your original link is 15 characters or 150. That means a long tracking URL with UTM parameters costs you the same 23 characters as a tiny link. This counter detects URLs in your text automatically and applies the 23-character rule, so the number you see is the number X will count. If you are adding campaign tracking to your links, build them with the UTM Builder first — the length of those parameters will not eat into your character budget.

Turning long posts into threads

Some ideas simply will not fit in 280 characters, and that is exactly what threads are for. The built-in thread splitter takes any long block of text and divides it into a sequence of tweets that each stay under the limit. It splits on word boundaries — never in the middle of a word — and appends a tidy numbering suffix like (1/5) so your readers can follow along. Each tweet in the thread comes with its own character count and a Copy button, so you can paste them into X one after another. Threads consistently earn more impressions and engagement than single tweets because they keep people scrolling, and a well-structured thread lets each point breathe instead of being crammed into one cramped post.

Why the character count matters for engagement

Knowing your count is not just about staying under the limit — it is a content strategy lever. The first roughly 100 characters of a tweet are what show before the "Show more" cut and what appear in previews, so front-loading your hook there is critical. Research on tweet performance has repeatedly found that shorter, punchier tweets often outperform ones that max out the limit, because they are faster to read and easier to retweet with a comment. Use this counter to test variations: write a long version, then trim it to a tight, scannable one and compare which lands better. Consistency in length and tone across your posts also builds a recognizable voice — and maintaining that voice at scale is where an AI assistant earns its keep.

From counting tweets to publishing everywhere

A character counter solves one slice of the problem — but most creators and brands are posting to far more than just X. That is where Outfeed AI comes in. Instead of bouncing between separate tools and dashboards, you chat with an AI assistant that writes, formats, schedules, and publishes posts across nine platforms — Instagram, TikTok, LinkedIn, X/Twitter, Facebook, Threads, YouTube, Pinterest, and Bluesky — from a single conversation. It learns your brand voice, tailors each post to the platform (including respecting X's 280-character limit automatically), and handles the publishing for you. Draft and trim your tweet here, then let Outfeed AI scale that same message everywhere your audience is.
