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.

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.

Frequently asked questions
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.
