Twitter Character Counter

How to Use the Twitter/X Character Counter

1. Type or paste your post into the box above.
2. Watch the weighted count and progress bar update as you write.
3. Pick Standard or Premium in the selector to check your draft against the 280 or 25,000 character ceiling.
4. Check the metric cards for your DM, bio, username, and profile name limits at the same time.

This twitter character counter follows the same counting logic as X's own compose box instead of just running a plain JavaScript string length check. Links get flattened to 23 characters, emoji get mapped to their real weighted cost, and wide-script characters are counted the way X counts them, not the way a text editor would. So the number you see here is the number X will actually use.

Nothing to install, nothing to configure beyond the posting-limit selector. Paste a draft, a bio, a DM, or a display name into the same box and the cards above tell you right away whether it fits.

What Is a Twitter/X Character Counter?

A twitter character counter tells you, before you post, whether your text fits inside X's length rules. That sounds straightforward until you realize X doesn't just count letters. It runs a set of weighting rules baked into the platform's own text-processing logic, the same rules the official twitter-text library uses to validate posts on the server side. A plain JavaScript character count will disagree with X's real number the moment a link, an emoji, or a non-Latin character shows up.

The idea behind it is "weighted length." Most Latin characters, digits, and punctuation cost one unit each, but a handful of categories cost more or get normalized to a fixed value. Knowing those exceptions is the difference between a counter that matches what X will actually accept and one that just leaves you guessing.

A couple of things this tool can't do: it can't see attachments, so polls, images, GIFs, and quote-tweet cards are left out of the total on purpose, since they're rendered separately by X and don't touch the character count. It also can't confirm live whether a link has already been wrapped by X's t.co shortener, so any URL-shaped string you paste is treated as if it will be, which is how X handles it in practice. And since emoji rendering varies a bit across devices and font sets, an unusual or brand-new emoji sequence might weigh a unit or two differently than what shows up in your own compose box.

Where People Use This

Get More From Every Character

Beyond a raw count, a few features and habits make this tool, and your posts, more useful.

Multi-Surface Counting Options

The same text box checks your draft against five different X surfaces at once: the post itself, a DM, a bio, a username, and a profile name. You don't need to re-paste your text into five separate tools to find out where it fits.

Real-Time Profile Metric Cards

Every card above updates on each keystroke, not just on submit, so you can watch a count climb toward a limit as you write instead of finding out after the fact.

Dynamic Visual Progress Feedback

The progress bar under the main weighted count shifts from orange to amber to red as you approach and then exceed your chosen limit, giving you a glance-able signal without having to read the numbers at all.

The 70 to 100 Character Sweet Spot

Plenty of engagement studies on short-form posts keep landing on the same finding: posts in the 70 to 100 character range tend to outperform both much shorter and much longer ones. They're long enough to say something real, but still short enough to read at a glance while scrolling. Treat 280 as a ceiling, not a target.

Hashtag Density Penalties

Stack too many hashtags into a post and it starts reading as spam, both to the feed algorithm and to actual people scrolling past it. One or two well-chosen hashtags usually beats filling up remaining space just because you have the room.

The Link Budget Strategy

Because every link costs a flat 23 characters no matter how long the underlying URL is, there's no benefit to pre-shortening a link before pasting it, and no penalty for linking to a long, descriptive URL. Spend the characters you save on a real reason to click instead of restating the link's destination in words.

Front-Loading Hooks for Premium Longposts

Premium's 25,000 character limit is generous, but the timeline still only previews roughly the first 280 characters before a "Show more" prompt. Put your strongest sentence first regardless of how long the full post runs, since that's the only part most scrollers will ever see unprompted.
