Meta Description Generator & Length Checker
Draft AI meta descriptions, check character + pixel length, and preview exactly how they’ll look in Google on desktop and mobile.
Write meta descriptions that actually get clicked
Your meta description is the ad copy for your search listing. It won’t directly move rankings, but it’s one of the biggest levers on click-through rate — and Google truncates it by pixel width, not character count, so a description that “looks” the right length can still get cut off with an ugly “…”. This tool does three jobs in one: it drafts options with AI, checks character and pixel length against Google’s limits, and shows a live SERP preview for desktop and mobile.
The rules of thumb
- Length: ~140–160 characters; stay under ~920px desktop / ~680px mobile.
- Keyword: include the primary term naturally — Google bolds matched query words.
- Uniqueness: every page needs its own description; never duplicate.
- CTA: give a reason to click — a benefit, a question, or a clear next step.
Remember Google rewrites descriptions about 70% of the time, so write the version you’d most want shown — then check it here before you publish.
