Enter any page URL and our SEO meta description checker fetches the <meta name="description"> tag, then shows the character count, pixel width, and a live Google SERP preview — so you know exactly how it'll look in search.
What is a meta description checker?
A meta description checker is a free tool that loads any web page, reads its <meta name="description">tag, and grades it for length, pixel width, and quality. It's also known as an SEO meta description checker, meta description tester, or meta description validator. Use it to check the meta description of any page in seconds — free and online.
Meta description length checker & character counter
The ideal meta description is about 120–160 characters. This meta description length checker and character counter shows the exact count with a sweet-spot bar, so you can quickly test meta description length and avoid descriptions that are too short or get cut off.
Meta description pixel checker
Google actually truncates descriptions by pixel width, not character count. Our built-in meta description pixel checkermeasures the rendered width of your text using Google's SERP font and flags anything over the ~920px desktop limit (and ~680px on mobile) — the most reliable way to predict truncation.
Google SERP preview
This SERP meta description tool renders a Google-style snippet with pixel-accurate truncation, so you can preview exactly how your description appears in the results before publishing.
How to use the meta description checker
Paste a page URL (the website/site meta description checker works on any public page).
Click “Check Meta Description” to fetch the live tag.
Review the character count, pixel width, verdict, and Google preview.
