Limits shown were last checked in October 2026 against published platform guides. Platforms change their limits from time to time, so for anything critical, confirm in the platform's own help centre.
About This Tool
Every platform cuts text off at a different point, and some hide most of a caption behind a "more" link long before the limit is reached. The Character Counter shows all of those limits side by side, so you can tune one piece of text for several platforms in a single pass instead of pasting it into each app to find out.
Counting follows the way the platforms count, where that is known: a link counts as 23 characters on X however long it is, and emoji and accented letters are counted as single characters. Everything is calculated locally in your browser as you type — there is no sign-in, no AI wait, and nothing is sent to a server.
How to Use It
01
Paste your text
Drop in a caption, post or bio. The counts and fit bars update on every keystroke.
02
Check each platform
Green means it fits, amber means you are close to the limit, red means it is over by the number shown.
03
Tidy it up
Use the formatting buttons to remove double spaces, add line breaks or change the letter case. Made a mistake? Undo restores the previous version.
04
Copy and post
Copy the finished text and paste it straight into the platform.
Frequently Asked Questions
Is my text stored or sent anywhere?
No. The counter runs entirely in your browser. Nothing you type is uploaded, saved or shared.
Why does X show a different count from a plain character count?
X counts every link as 23 characters regardless of its real length, so the X bar applies that rule. Other platforms count the text as typed.
What does “shown before more” mean for Instagram?
Instagram shows only the first part of a long caption in the feed and hides the rest behind a “more” link. Roughly the first 125 characters are visible, so that is where your hook belongs. It is a guideline, not a hard limit.
How current are the limits?
They were last checked in October 2026 against published platform guides. Platforms change limits occasionally, so confirm important ones in the platform's help centre.
Does it work for languages other than English?
Yes. Characters are counted as written, including accented letters and emoji. Word and sentence counts work best for languages that separate words with spaces.
