UMARIX Social Media ToolsCharacter Counter
Every platform limits text differently, and a caption that fits Instagram may be far too long for X. Paste your text below to see character and word counts, reading time, and how it compares with common reference limits. Limits change, so treat the platform figures as a reference and check the platform help center before you publish an important post.
Reference limits (check the platform help center for current rules): X post 280 characters | Instagram caption 2,200 | Instagram bio 150 | LinkedIn post 3,000 | Facebook post 63,206.
How to use
- Paste or type your caption, bio, or post in the box.
- Read the character, word, and line counts.
- Compare the result with the platform reference limits shown.
- Trim the text or split it before you publish.
Frequently asked questions
What is the X character limit?
As a reference, a standard X post is 280 characters. Longer posts may be available with paid options, so check the current X help center.
What is the Instagram caption limit?
As a reference, an Instagram caption is 2,200 characters and a bio is 150 characters. Check the current Instagram help center for updates.
Do spaces count as characters?
Yes. The counter counts letters, spaces, and punctuation, because platforms count them too.
Why does my text show over the limit but still post?
Some platforms count links, mentions, or formatting differently, or the limit may have changed. The platform itself is the final check.
