SERP simulator
Type a title and description and instantly see how they’ll appear in Google’s search results, and where they get cut off.
The limits are estimates, not gospel
Google publishes no exact figures and the sources disagree. For the title, Screaming Frog historically measured 482 px, while today’s tools work with more like 580 – 600 px. For the description the spread is even wider: it actually renders around 930 – 940 px, Mangools lists a 960 px limit, Screaming Frog up to 1005 px. We take the more cautious numbers from that range.
On mobile the limit is a budget, not a line width
A mobile title wraps onto two lines; Google doesn’t cut it at the end of the first. The 490 px limit is therefore a total text budget, not the width of a single line. That’s why a 467 px title wraps in the preview and still passes. Treat the mobile figures as indicative rather than an exact cut-off.
Google may rewrite your title anyway
In roughly 60% of cases Google rewrites the title in the results itself, based on your H1, link text or brand name. It may also add a date to the description or bold words from the query, which eats a few pixels. This tool tells you whether your draft fits, not whether Google will use it.
We measure in the browser
The text is drawn onto a hidden canvas in Google’s font (Arial 20 px for the desktop title, 18 px for mobile, 14 px for the description) and its real width is measured. Nothing is sent anywhere; your data stays in your browser. Font rendering differs by a few pixels between Windows, Linux and macOS.
