Character Limit Checker
Check your text against the exact character limits for X/Twitter, meta descriptions, SEO titles, LinkedIn, and Instagram. The live counter warns you before you go over — and it all runs in your browser, so nothing is ever uploaded.
Why Use This Character Limit Checker?
Every platform truncates text at a different point, and most editors don't tell you until it's too late — your meta description gets cut mid-sentence in Google, or your tweet refuses to post. This tool counts the way platforms actually count: it uses the Intl.Segmenter API at grapheme granularity, so an emoji like 👨👩👧👦 registers as one character, not the seven code units JavaScript's naive string.length would report. Pick a preset, watch the live gauge, and ship copy that fits the first time.
Real Platform Limits: Presets for X/Twitter (280), meta descriptions (160), SEO title tags (60), LinkedIn posts (3,000), and Instagram captions (2,200) — the numbers that actually trigger truncation, not rounded guesses.
Emoji-Accurate Counting: Built on Intl.Segmenter grapheme segmentation, so multi-codepoint emoji and combining accents count as a single user-perceived character — exactly how the platform's own counter behaves.
Live Color Warning: A gauge shifts from green to amber to red as you approach and cross the limit, and the exact overage is shown so you know precisely how much to cut.
Copy Trimmed to Fit: One click copies your text sliced cleanly to the limit, so you can paste a guaranteed-to-fit version without manually counting backwards from the end.
Private by Design: The text never leaves the page — there's no upload, no account, and no logging. Everything runs in your browser's JavaScript engine, so confidential drafts stay confidential.
