Free tool
Type a title, URL and description and watch the result build on desktop and mobile. Google truncates by pixel width, so this measures the rendered width of your text instead of counting letters.

Why pixels
A title of 60 capitals is far wider than 60 lowercase letters, and an em dash is wider than an i. Two titles of identical length can truncate in different places, which is why a character counter alone will mislead you.
This tool renders your text to a canvas and measures it, so the pixel figure is real. The threshold it is compared against is a community approximation, because Google has never published one and changes its layout without notice.
Mobile results are narrower and use a smaller title size, so a title that survives on desktop can be cut on a phone. Since most searches happen on mobile, check that view before you decide a title fits.
Titles are rewritten when Google judges another string a better match for the query, and descriptions are substituted for on-page text very frequently. A snippet that accurately reflects the page is the one most likely to survive.
Method
This shows length and truncation, and nothing else. It cannot tell you whether the snippet will win the click, because that depends on the query, the nine other results on the page and the person searching. It also cannot show rich result features such as sitelinks, ratings or dates, which depend on your structured data and on Google choosing to display them.
If titles across a whole site need rewriting, that is a content audit rather than a preview.
FAQ
A SERP preview tool renders a mock-up of how a page will appear in a search engine results page, using the title, URL and meta description you supply. It shows where each element will be cut off, so you can adjust the wording before publishing rather than discovering the problem in a live result. SERP simply stands for search engine results page.
Google truncates titles by pixel width rather than character count, at roughly 600 pixels on desktop, which works out around 60 characters for typical mixed-case text. Because width depends on the actual letters, a title in capitals or full of wide characters is cut much sooner than a lowercase one of the same length. Measuring the rendered width, as this tool does, is more reliable than counting.
Google rewrites titles when it judges a different string a better match for the query, and it replaces meta descriptions with on-page text very frequently. It also personalises results by location, device and search history, and may add features such as sitelinks or dates. A preview shows what you have supplied, not what Google will finally choose to display.
Check both, and treat mobile as the stricter constraint, since mobile results are narrower and most searches now happen on phones. A title that fits comfortably on desktop can lose its final words on a small screen, which usually means losing the brand name or the qualifier at the end. Front-loading the important words solves this for both views at once.
No. Previewing a snippet changes nothing about the page and neither titles nor descriptions guarantee a position. Titles are a modest ranking input and descriptions are not a ranking factor at all; what both genuinely affect is whether a searcher clicks the result you already earned.
It is free with no signup, and the preview runs entirely in your browser, so nothing you type is sent anywhere. Only the optional snippet report, which scores the title, URL and description against a published set of checks, asks for an email address.
