About SERP Preview
Google does not cut titles at a character count — it cuts them when they run out of horizontal room, and letters are not equal. A title of sixty narrow characters measures about 266 pixels at the 20px size Google uses for desktop titles; sixty wide ones measure about 667 pixels and get an ellipsis. Any tool that judges your title on a character count alone is guessing, which is why this preview measures the actual width of the string you typed using Arial advance widths, the same font metrics a browser uses to lay out a real result.
Both previews are drawn to the real geometry. The desktop card is a 600px column with a 20px title on a single line and a 14px snippet over two; the mobile card is a 360px column with an 18px title over two lines and a snippet over three. The wrap and the ellipsis are placed by the same measurement shown in the numbers underneath, so if the preview cuts your description mid-sentence, that is where the budget genuinely ran out. The URL you paste is parsed into the site name and breadcrumb path Google now shows above the title, so a deep, slug-heavy path looks the way it will in search.
It is worth being clear about what a preview cannot know. Google frequently rewrites titles when it judges another heading on the page to be a better match, and the snippet it shows is assembled per query, so the description you wrote is a strong suggestion rather than a guarantee. Dates, sitelinks and rating stars all consume space in the same block. Use this to catch the avoidable problem — a title or description that cannot possibly fit — and to make sure the first few words carry the message, because those are the ones that survive every kind of truncation.
