## Letters, characters, and what platforms actually count

In everyday use “letter count” and “character count” mean the same thing: every keystroke of visible text. Most platform limits — tweets, bios, meta descriptions, SMS — count every character including spaces and punctuation, so the with-spaces number is usually the one that matters. The no-spaces figure is there for the assignments and forms that ask for it explicitly.

## Common limits worth knowing

A single SMS is 160 characters; an X/Twitter post is 280; an Instagram bio is 150; a Google search snippet comfortably shows about 155–165 characters of a meta description; and LinkedIn headlines cap at 220. Paste your draft above and the live count tells you exactly how much room is left before a platform truncates you.

## Why letters-per-word matters for readability

Texts packed with long words are objectively harder to read — readability formulas like Flesch Reading Ease score word length directly. If your average word length is creeping up, swapping a few long Latinate words for short ones does more for clarity than any other single edit. Check the full picture with the free readability checker.

## Free, unlimited, and private

The letter counter is free with no sign-up and no limit on how much text you process. Because it runs entirely in your browser, your text is never sent to a server, stored, or used to train any AI — it never leaves your device. When you’re ready to do more with your writing, Humanit’s AI humanizer and AI detector are one click away.

## FAQ

**Does the letter count include spaces?**

Both numbers are shown live: characters with spaces and without. Most platform limits count spaces, so the with-spaces figure is usually the one to watch.

**Are numbers and punctuation counted as letters?**

They are counted as characters — which is what nearly every real-world limit measures. If a form asks for strictly alphabetic letters only, use the no-spaces figure as your closest guide and subtract digits manually.

**Is there a length limit on what I can paste?**

No. The counter runs entirely in your browser, so it handles anything from a tweet to a full manuscript instantly.

**Do I need an account?**

No. There’s no sign-up and no install — open the page and start typing.

**Does it work on mobile?**

Yes — it works in any modern browser on phone, tablet, or desktop.
