Why measure pixels when every other tool counts characters?

Because Google lays out the snippet in a proportional typeface, where a lowercase "l" is roughly a quarter the width of a capital "W". A sixty-character title made of narrow letters fits comfortably; a fifty-character title in capitals does not. Character counting is a rule of thumb that was built for a monospaced world and it is wrong in both directions, which is the least useful way for a limit to be wrong.

Does Google actually show the title I write?

Often, but not always. Google has rewritten displayed titles since 2021, and it substitutes an H1 or anchor text when it judges your title to be a poor match for the query, keyword-stuffed, or boilerplate-heavy. Writing a title that fits and describes the page honestly is the way to keep it; treating the tag as guaranteed placement is not.

What are the pixel limits it checks against?

Roughly 580px for a desktop title and about 920px of description across two lines, with narrower limits on mobile. These are observational rather than published — Google documents no limit at all — so the tool shows the measurement and marks the widely observed cut-off rather than claiming an official number exists.

Should I write to fill the whole width?

No. Fill it when you have something to say and stop when you do not. A description padded to 160 characters to hit a green bar reads like it was written for a bar, and a snippet that stops early is not penalised. The limit is a ceiling, not a target.

Pixels, not characters

Every guide that tells you to keep titles under sixty characters is quoting a rule of thumb derived from an average, and the average hides the thing that decides the outcome. Google renders the snippet in a proportional typeface. A capital W is roughly four times the width of a lowercase l. So "Willingham Williams Worldwide Warranty" and "illinois lilies fill little tills" are the same length in characters and nowhere near the same length on screen.

This tool measures the string with the browser's own text engine, at the size and family Google uses, and reports the result in pixels. The character count is still shown, because it is the number your CMS validates against, but the pixel figure is the one that decides whether the sentence survives.

The limits it marks

Around 580 pixels for a desktop title and roughly 920 pixels of description across two lines; on mobile the title has less room but the description has more, because the snippet is allowed to run to three lines. These figures are observational. Google publishes no character or pixel limit and has said repeatedly that there is not a single correct length, so any tool showing you a hard red line at an official number is showing you a number nobody official ever gave.

Treat the marks as a warning that truncation is likely rather than a rule you have broken. Being cut off is not a ranking problem in itself. It is a communication problem, and only when the part that got cut was carrying the reason to click.

Write for the truncation, not around it

The practical technique is front-loading. Put the distinguishing information in the first third of the title and the brand at the end, where losing it costs nothing. A title that reads "Acme Corporation | Industry Leading Solutions | Widget Pricing and Plans" spends its entire visible width before reaching the only word a searcher was looking for.

For descriptions, write two sentences and let the second one be the expendable one. Google frequently ignores the meta description entirely and lifts a passage from the page that matches the query more closely, which is worth knowing before spending an afternoon polishing one: the description influences the click, never the ranking, and only when Google chooses to use it.

Checking what is live

This previews a string you paste. Confirming that the string is what your live page actually serves — after the CMS, the template and any plugin that rewrites tags — needs a fetch of the URL, which this page cannot perform. Thetitle tag checker andmeta description checker on visibility100x.com do that server-side and report what is really in the head.
