Free Character Counter for Social Media & Ads
Every platform enforces its own character limit, and going over means your best line gets truncated — or won’t post at all. This tool checks your text against the published limits for the major social networks, ad formats and SEO fields all at once, so you can write once and reuse everywhere with confidence.
How to use it: paste your text into the box, pick a category (Social Media, Advertising, or SEO & Web), and each platform card shows your live character count against that limit. Cards turn green when you’re within the limit and red the moment you go over, with the exact number of characters you need to trim.
Note on limits: some platforms (like Facebook posts and ad primary text) allow a very high maximum but only show the first ~125–480 characters before a “See more” cut-off, so aim well under the hard limit for anything that needs to grab attention up front.

What is the Character Counter Tool?
A free online character counter that checks your text against the real character limits for every major social media platform, ad format and SEO field at once. Paste your post, caption or ad copy once, choose a category, and each brand-coloured platform button shows your live character count — turning red the instant you go over the limit for X (Twitter), Instagram, Facebook, TikTok, LinkedIn, YouTube, Google Ads, Facebook Ads and more. No sign-up, and everything is counted instantly in your browser.
Example: trimming a Google Ads headline to 30 characters
Google Ads caps headlines at 30 characters. You paste your draft — “Professional Carpet Cleaning Services in London” — and the counter shows 47 characters. You tighten it to “Carpet Cleaning London – Pro Team” at exactly 30 characters, fitting the limit without losing the core message.

Watch for red
Any platform you are over the limit for turns red and tells you how many characters to cut. Green means you are good to publish.
Why This Matters for SEO
Every platform truncates or rejects text that exceeds its character limit, and a chopped-off headline or caption costs you clicks and engagement. Meta titles and descriptions get cut in search results, tweets that are too long simply will not post, and ad copy that overruns is silently trimmed — often mid-sentence. Checking your character count against the correct limit before you publish makes sure your full message is seen everywhere you post it.
