Pixel limits (~580 px for titles, ~920 px for descriptions on desktop) are estimates: Google adjusts them often and may rewrite your snippet.
About this meta title and description checker
Type your page title and meta description and watch the counters update live: character counts plus pixel-width estimates measured with the canvas API at Google’s approximate font sizes (20 px for titles, 14 px for descriptions). Each field gets a traffic-light status against the commonly cited desktop limits — about 580 px for titles and 920 px for descriptions — and a Google-style preview shows your snippet as it would render, ellipsis included.
Pixel measurement matters because Google truncates by width, not by character count: a title full of wide capitals like W and M gets cut sooner than one built from narrow letters. The classic advice of 50–60 characters for titles and 140–160 for descriptions is a good rule of thumb, but the pixel estimate is what actually predicts the cut. Everything runs locally in your browser, so titles and descriptions for unpublished pages never leave your device.
How to add a meta description, and write one worth clicking
The tag itself is one line in the page head. Everything this tool measures is the text inside content.
<meta name="description" content="Format, validate and minify JSON in your browser — nothing is uploaded.">Most people never touch raw HTML. Here is where the field lives in the common platforms:
| Platform | Where the field is |
|---|---|
| WordPress + Yoast SEO | In the Yoast box under the editor, open the Google preview and fill the Meta description field. |
| WordPress + Rank Math | Click Edit Snippet, then the Description field. |
| Shopify | On a product, page or collection, edit the Search engine listing and fill the description. |
| Squarespace | Page Settings, then SEO, then SEO Description. |
| Wix | Page, then SEO Basics, then the description field. |
A good description earns the click, it does not just fit the ruler:
| Weak | Better | Why |
|---|---|---|
| Free online tools. | Format, validate and minify JSON in your browser — nothing is uploaded. | Vague versus specific and benefit-led. |
| json tool json formatter format json online free | Paste messy JSON and get it clean, with the exact error if it is invalid. | Keyword-stuffed versus one clear promise. |
| The same line on every page | One unique sentence per page. | Duplicates give Google nothing to choose between. |
Honest caveat: Google rewrites the description for most searches, so treat the length target as what to aim for when Google does use yours, not a guarantee. Write for the click, not the character count.
FAQ
Does Google always use my meta description?
No. Google rewrites the snippet for a majority of pages, often pulling text from the page itself that better matches the search query. A well-written meta description still matters: it is used more often for branded and high-intent queries, and when it does appear it works as your free ad copy in the results.
Why measure in pixels instead of characters?
Because Google truncates by rendered width — roughly 580 px for desktop titles and 920 px for descriptions — not by a fixed character count. "WWW" occupies about three times the width of "iii", so two 60-character titles can behave very differently. Character ranges like 50–60 are just a convenient shorthand for typical widths.
Are the limits different on mobile?
Yes. Mobile results use different fonts and available widths, and often show a bit more description text than desktop. Google also changes these limits without notice, which is why this tool labels everything as an estimate. Front-load your key message in the first ~120 characters and it will survive on any device.
