Free Online Google SERP Preview Tool

1. Type or paste your page title, meta description and URL into the fields.
2. Watch the character count and estimated pixel width update, with a note on whether each fits.
3. Toggle between desktop and mobile to see how the snippet changes on each device.
4. Trim anything marked "will truncate" and move your key terms toward the front.
5. Use the live snippet as a final visual check before adding the tags to your page.

A search engine results page (SERP) snippet is made of three parts: the clickable title link, the green/grey URL or breadcrumb, and the description text beneath it. Google does not truncate these by character count — it truncates by rendered pixel width. Desktop titles display to roughly 580 pixels (about 60 characters) and descriptions to roughly 920 pixels (about 155-160 characters); mobile shows slightly less. Because letters have different widths — a 'W' is more than twice as wide as an 'i' — two titles with the same character count can cut off at very different points.

This preview estimates the rendered width of your text using per-character width weights, then truncates at the desktop and mobile limits so you can see the likely cut-off before publishing. Type a proposed title and description and watch the snippet update live; front-load important words so they survive truncation.

The preview is a close simulation, not a guarantee. Google frequently rewrites titles, appends the brand or a date, adds sitelinks, and varies truncation by query and device. Treat the result as guidance for writing snippets that fit, not as a pixel-perfect promise.
