SERP preview
A character count is the wrong instrument. Google truncates on rendered width, so two titles of the same length can be cut in different places — this one measures the width.
Runs entirely in this page. Nothing is uploaded, stored or sent anywhere.
Write it, then measure it
Pixels, not charactersThe dashed rule down the right of the specimen is the measured cut point, not a border. Widths are exact against Arial; the limits they are measured against are the widely observed desktop truncation points, and a phone wraps to a line budget that varies by device and is not published — so the mobile reading reports how full the last line is rather than declaring a pass.
Common questions
What it does, and what it does notHow many characters can a title tag be?
Characters are the wrong unit, which is why the advice never quite works. Google truncates on rendered width: roughly 600px for a desktop title set at 20px Arial. A 58-character title of capitals and em dashes overruns that; a 70-character title of short lowercase words fits inside it. This tool measures the width rather than counting the characters, and reports the character count only so you can see the two disagree.
Why does Google show a different title from the one I wrote?
Because it rewrites them. Google replaces a title or a description whenever it judges another string a better answer to the query, and it very often builds the snippet from a passage in the page body rather than from the description at all. A preview shows what you have offered it, not what it will display.
Is the preview pixel-exact?
The measurement is exact against Arial: the advance-width table it uses was read out of a browser canvas with measureText and checked against it, and a 148-character reference string measures the same by both methods. What is not exact is the engine: the truncation points are the widely observed desktop figures, and a phone wraps to a line budget that varies by device and build and is not published. So the widths are measured and the limits are observed — the page says which is which.
Does it fetch my page?
No. You paste the title and the description, and it measures them in your browser. The page makes no network request of any kind — the site sets a Content Security Policy of connect-src none, so it could not fetch a URL even if it tried.
These answers describe the implementation rather than an intention: this page makes no network request of any kind, which is enforced by the site’s Content Security Policy and checkable in the source.
