Character Counter for Twitter, Instagram, and LinkedIn Limits
Count characters with and without spaces. See exactly where you stand against platform-specific limits for Twitter, Instagram, LinkedIn, and more.
The problem
You're drafting a tweet and you're not sure if it fits in 280 characters. You're writing a LinkedIn post and you want to stay under 3,000. You're crafting a meta description and need to keep it under 160. Every platform has its own limit, and most text editors don't show character count at all — let alone tell you whether you're over or under a specific platform's threshold. You end up posting, hitting the limit, and awkwardly trimming your text in a tiny edit box.
How it works
- Paste or type your text — the character count updates instantly as you type.
- See counts with and without spaces — some platforms count spaces, others don't. You get both numbers.
- Check platform limits — see at a glance whether your text fits within Twitter, Instagram, LinkedIn, YouTube, SMS, and other common limits.
Your text never leaves your browser. Nothing is stored, nothing is sent to a server.
When to use this tool
Writing social media posts and checking against character limits before publishing. Drafting SEO meta descriptions that need to stay under 160 characters. Writing SMS messages that should fit in a single 160-character segment. Checking ad copy against Google Ads headline limits (30 characters) and description limits (90 characters). Any time the exact character count matters and you need to know it before you submit.
Why I built it
I was writing meta descriptions for these tool pages and kept guessing whether they'd get truncated in search results. A simple character counter that also shows me the relevant platform limits, right there in the same view, saves a lot of back and forth.
Tips and reference
Common character limits: Twitter/X posts are 280 characters. Instagram captions are 2,200. LinkedIn posts are 3,000. YouTube titles are 100, descriptions 5,000. Google Ads headlines are 30 characters, descriptions 90. SMS messages split at 160 characters (or 70 for Unicode). Meta descriptions display about 155-160 characters in search results. Keep a mental shortlist of the platforms you use most, and you'll rarely get caught by a limit again.
