Google's real truncation varies by device, query and rendering — these pixel limits are close approximations, not exact.
A SERP snippet is the title, URL breadcrumb and description Google renders for a result, and it is cut to a pixel width rather than a character count — about 580px of 20px Arial for a desktop title, narrowing to 490px on mobile. See how your page looks in Google and keep the title and description within the limits — the snippet updates live as you type, with pixel-width truncation for desktop and mobile. Everything runs in your browser.

Google's real truncation varies by device, query and rendering — these pixel limits are close approximations, not exact.
Type your title tag, page URL and meta description into the form. The Google-style result card on the right updates live, truncating each part with an ellipsis at Google's approximate pixel limits — 580px for the title and 920px for the description on desktop, 490px and 680px on mobile — so you can see roughly where the text will be cut. Widths are measured with an HTML canvas in the fonts Google renders the snippet in: 20px Arial for the title and 14px Arial for the description. Under the title and description fields, a counter shows the character count and the measured pixel width, turning amber and then red as you pass the recommended length.
Switch between Desktop and Mobile to check both layouts, since mobile results are narrower and cut sooner. Because Google truncates by pixel width rather than character count, a title packed with wide letters runs out of room faster than a shorter-looking one. Ready to write the tags?
