Check your social media text length instantly with our Social Media Character Counter. Count characters, words, spaces, and more to keep posts, captions, bios, and updates within your desired limits.
How to Use
- Select a platform from the dropdown — X/Twitter, Instagram Caption, Facebook Post, LinkedIn Post, Instagram Bio, YouTube Description, or No Limit.
- Type or paste your text into the text box.
- Watch the live stats — character count, word count, sentence count, and line count update as you type.
- Check the remaining count — see exactly how many characters you have left for your selected platform's limit. It turns red if you go over.
- Copy or clear your text using the buttons below the stats whenever you're ready.
Features / Benefits
- Platform-specific limits — built-in presets for X/Twitter, Instagram captions and bios, Facebook, LinkedIn, and YouTube descriptions.
- Four live metrics — characters, words, sentences, and lines, all updating in real time as you type.
- Over-limit warning — the remaining count turns red the moment your text exceeds the selected platform's limit.
- No-limit mode — switch off limits entirely for general writing or drafting.
- One-click copy and clear — manage your draft without needing to manually select text.
- Instant, private, and free — all counting happens locally with no character limit on how much you can check.
Detailed Information
The Social Media Character Counter calculates four separate metrics every time your text changes: total characters (including spaces and punctuation), word count (based on whitespace-separated tokens), sentence count (based on sequences ending in ".", "!", or "?"), and line count (based on line breaks in your text).
When you choose a platform preset, the tool compares your live character count against that platform's typical limit — for example, 280 for X/Twitter posts or 2,200 for Instagram captions — and shows exactly how many characters you have remaining, or how far over the limit you currently are.
All calculations run instantly in JavaScript as you type, so there's no delay or need to click a "check" button.
Common Uses / Examples
- Drafting tweets/X posts — confirm your post fits within 280 characters before publishing.
- Writing Instagram captions — check your caption stays under the 2,200-character cap, especially for longer storytelling posts.
- Polishing an Instagram bio — make sure your bio fits within the 150-character limit.
- Long-form LinkedIn or Facebook posts — track word and sentence count to keep posts scannable and readable.
- YouTube descriptions — verify your description doesn't exceed the 5,000-character limit before saving your video details.
Tips / Best Practices
- Write first, trim second — draft naturally, then use the counter to identify where to cut if you're over the limit.
- Watch sentence count for readability — very few, very long sentences can hurt engagement even if you're within the character limit.
- Double-check bios separately — Instagram bios have a much smaller limit (150 characters) than captions, so switch presets accordingly.
- Use No Limit mode for brainstorming, then switch to your actual target platform once you're ready to finalize the text.
Privacy & Security
All text you type into the Social Media Character Counter is analyzed locally in your browser using JavaScript. Nothing is uploaded, logged, or stored on any server — you can safely paste drafts, unreleased announcements, or private notes to check their length without concern about data exposure.
Conclusion
The Social Media Character Counter takes the guesswork out of writing for character-limited platforms. With live character, word, sentence, and line counts plus built-in platform presets, you can confirm your post fits before you ever hit publish.
FAQ
Which platforms have built-in limit presets?
X/Twitter, Instagram Caption, Instagram Bio, Facebook Post, LinkedIn Post, and YouTube Description are all included, plus a No Limit option.
Does it count emoji as one character?
The counter uses standard JavaScript string length, which counts most emoji as one or two characters depending on the specific emoji — similar to how many platforms count them.
Can I use this for languages other than English?
Yes, the counter works with any Unicode text, though word-splitting is based on spaces, which works best for space-separated languages.
Is there a limit to how much text I can check?
No, you can paste text of any length, even in No Limit mode.
Is my text saved anywhere?
No, all counting happens locally in your browser and nothing is transmitted or stored.
