Why character limits are tricky
Every platform sets its own limit, and they don't all mean the same thing. X (Twitter) posts cap at 280 characters, Instagram bios at 150, LinkedIn posts at 3,000, and Facebook technically allows over 60,000 — though only the first couple of lines show before "See more." Checking each one by hand for every piece of copy is slow.
What's included
- Live character counts, with and without spaces
- 43+ built-in platform presets — social media, ad platforms, app store listings, SEO meta tags, and more
- A custom limit field for any platform not on the list — type any number and see exactly how many characters you have left
- Clear status indicators (OK / Near limit / Over) for every platform at a glance
Common limits at a glance
- X (Twitter) post: 280 characters
- Instagram bio: 150 characters
- Meta / SEO title: 60 characters
- Meta / SEO description: 160 characters
- SMS (1 segment): 160 characters
One shared editor for everything
The character counter uses the same text box as Toolioh's word counter, case converter, and grammar checker — write your copy once, then check length, fix case, and catch typos without switching tools.
More than a simple letter counter
Use it as a plain letter counter to count characters online, or switch to character count without spaces when a platform's limit is defined that way. It works as a tweet character counter, an Instagram caption character limit checker, and a meta description length checker for SEO — all from the same characters and words counter panel, functioning as a full text length calculator for any format.
Does it count characters with spaces or without?
Both — the tool shows character counts with spaces and without spaces side by side, so you can check against either definition of a platform's limit.
Can I check my Instagram caption or tweet length?
Yes — Instagram, X (Twitter), and 40+ other platform limits are built in and update live as you type.
