How to use it
Type or paste your text into the box. As you write, ToolFern counts your characters, words and lines, then shows a table of common platforms with the characters remaining for each. When your text goes over a platform’s limit, that row turns red and tells you exactly how many characters you are over, so you know precisely how much to trim.
The limits we check
We track the limits people bump into most often: Twitter/X (280 characters), Instagram caption (2,200), Instagram bio (150), a single SMS (160), the meta description Google typically shows (about 160), and the title tag (around 60 before it gets truncated in search results). These are practical guidelines that help your text display cleanly across the web and social apps.
How the counting works
All counting happens inside your browser as you type, updating instantly with no sign-up required.
Frequently asked questions
Do emojis count as one character?
This tool counts characters the way JavaScript does, so most emojis count as one or two characters. Some platforms count them differently, so treat the numbers as a close guide.
Why does the title tag limit say 60?
Search engines usually display roughly the first 60 characters of a title before cutting it off, so staying under 60 keeps your full title visible.
What character limits does it check?
Twitter/X (280), Instagram caption (2200), Instagram bio (150), SMS (160), Meta description (160) and Title tag (60). Each row turns red and shows how many characters you are over when you exceed the limit.
Why is the SMS limit only 160 characters?
A single GSM-encoded SMS holds 160 characters. Longer messages are split into multiple segments, which can cost more to send.
