SERP Snippet Preview and Title Length Checker

Google cuts long titles and descriptions by width, not by character count, so a title of wide capitals is cut sooner than one of narrow letters. Aim for titles under about 600 pixels (roughly 50 to 60 characters) and descriptions under about 920 pixels on desktop. Type yours below to see the cut in pixels.

Measure a title and description the way a result is drawn, see the desktop and mobile versions side by side with your keyword in bold, and paste a whole list of pages to find the ones that will be cut.

Why pixels beat characters

Arial at 20 pixels draws a capital W about three times as wide as a lowercase i. A 60-character title in all capitals can be cut well before one in sentence case. Counting characters hides that difference; measuring pixels shows it.

This tool measures with a canvas in your browser using Arial, the font Google results use on most systems. If your device lacks Arial, the browser substitutes a similar sans-serif and the widths shift slightly.

What Google actually uses

The title link usually comes from the page's title element, but Google may also draw on the main heading, prominent text or the text of links pointing to the page. The snippet usually comes from page content that matches the search, with the meta description used when it describes the page well.

So the best way to keep your own wording is simply to write an accurate, specific title and description for each page and to keep them in line with what the page says.

How it works

  1. Enter the page URL, title and meta description. The site name and breadcrumb are built from the URL.
  2. Each line is measured in pixels with the browser's own text renderer, using the fonts Google results use.
  3. The desktop preview cuts each line where it would run out of room and adds the ellipsis; the mobile preview wraps the text in a phone-width box.
  4. Add a keyword to see it in bold, the way Google highlights words that match the search.
  5. Paste many lines as title | description in the bulk checker to get pixel widths for each page.

Tips

Frequently asked questions

How long should a meta description be?

Google has no fixed limit and cuts snippets to fit the device. In practice, about 150 to 160 characters (around 920 pixels) shows in full on desktop for most text, and mobile shows less. Write the key point in the first 120 characters so it survives either way.

How long should a title tag be?

Keep it under about 600 pixels, which is usually 50 to 60 characters. Longer titles are not penalised, but the end is replaced by an ellipsis, so whatever comes last may never be read.

Why does Google show a different title or description than mine?

Google rewrites title links and snippets when it thinks other text on the page describes the result better for that search. It happens more with titles that are very long, stuffed with keywords, the same across many pages, or out of step with the page's main heading.

Is the preview exact?

No preview can be exact, because Google changes its layout, adjusts widths by device and sometimes adds dates, ratings or site links. The pixel measurement is a good guide to where text will be cut, which is what matters when you are writing.
