Instagram character counter
Paste or type your caption and see, as you type, how it fits every limit: Instagram captions and bios, TikTok, YouTube titles and descriptions, X, Threads and LinkedIn. It also shows the first line people see before “more”. Nothing you type leaves your browser.

Questions
About the Instagram character counter
What is the Instagram caption character limit?
2,200 characters, including hashtags and line breaks (checked November 2026). Instagram shows only the start of the caption before “more”.
What is the Instagram bio character limit?
150 characters, and line breaks count (checked November 2026).
What is the X (Twitter) character limit?
280 characters for accounts without Premium (checked November 2026). X weighs links and some characters, like emoji, differently, so its own counter can differ from this one.
What is the LinkedIn post character limit?
3,000 characters for a post, and 220 for a headline (checked November 2026).
How does it count emoji?
As one character each, the way you see them. Some platforms count certain emoji as two, so leave a little room when you're right at a limit.
Is this character counter free?
Yes. It's a free tool with no sign-up and no limit on how many times you use it.
