Character Counter

What the character counter measures

This tool counts every character in your text two ways: including spaces and excluding them. It also reports byte size, which matters more than most people expect — a character count and a byte count aren't the same thing once accented letters, emoji, or non-Latin scripts are involved, since those can take up two, three, or four bytes each in UTF-8 rather than one.

The count updates as you type, so you can watch it climb toward a platform's limit in real time instead of writing a draft blind and finding out afterward that it's ten characters too long.

Why character limits exist — and why they're strict

Most platforms that enforce a character limit do so at the API or database level, not just in their UI, which is why going over by even one character can cause an outright rejection rather than a gentle truncation. Google typically displays somewhere around 155–160 characters of a meta description before cutting it off with an ellipsis, X (formerly Twitter) counts to 280, and SMS messages split into multiple segments past 160 characters of plain text.

Because these limits are enforced in characters rather than words, two sentences with the same word count can have very different character counts depending on average word length — which is exactly the gap this tool is built to close.

Common use cases

SEO writers use it to fit page titles and meta descriptions inside the length search engines will actually display. Social media managers use it to check captions against each platform's limit before scheduling a post. Developers and form designers use it to test sample input against a database column's maximum length or an API field's character cap, and customer support teams use it to keep canned replies within an SMS or push-notification limit.

Tips for working with character limits

When you're close to a limit, check the count including spaces first, since that's what almost every platform enforces — the spaces-excluded number is mainly useful for print or typesetting contexts where whitespace is handled separately. If your text includes emoji, be aware some platforms count a single emoji as two characters internally (this tool reports the count as most people visually perceive it, which can occasionally differ from a platform's raw technical count by a character or two for emoji-heavy text).

Character limits across common platforms

Knowing the limits you're actually writing against makes this tool more useful than checking a count in isolation. X (formerly Twitter) posts cap at 280 characters, SMS text messages split into new segments past 160 characters, Google typically truncates meta descriptions somewhere around 155–160 characters and page titles around 60 characters, and many CRM and database systems cap short text fields at a fixed length like 100 or 255 characters. LinkedIn posts, YouTube titles, and app store listings each carry their own limits too, and all of these are enforced in raw character count rather than word count, which is exactly why a character counter — not a word counter — is the right tool for staying inside them.

Because limits vary so much from platform to platform, it's worth checking the specific number for wherever your text is headed rather than assuming a general rule of thumb will hold across all of them.
