Title Tag Pixel Width Checker
Paste one title per line and get the pixel width, character count, and truncation point for every single one. Google cuts titles by pixels, not characters, and this measures the real thing.
Blank lines are ignored. Everything runs in your browser, nothing is uploaded.
How the measurement works
The checker draws each title onto an invisible canvas at 20px Arial, the same font metrics Google uses for desktop result titles, and reads back the rendered pixel width. Anything at or under 534px fits comfortably, 535 to 580px is flagged as close, and anything past 580px gets truncated. For truncated titles the result row shows the exact split: the part that survives in normal color, and the part Google would cut struck through and dimmed.
Writing inside the pixel budget
- Front-load the keyword and the differentiator. If a cut comes, the surviving portion should still earn the click on its own.
- Treat the brand suffix as expendable. Losing " | Brand" to the ellipsis is harmless. Losing your primary keyword there is not.
- Watch wide characters. ALL CAPS, W, M, and numbers eat budget fast. "WWW" costs roughly what "till" costs three times over.
- Aim for 480 to 534px. Comfortably under the limit, but long enough to occupy the full SERP line and state a complete value proposition.
Frequently asked questions
Why measure titles in pixels instead of characters?
Because Google does. The desktop SERP gives a title roughly 580 pixels of room in a 20px Arial font, then cuts it with an ellipsis. A title packed with wide letters like W, M, and capitals can truncate at 50 characters, while a narrow one full of i, l, and t can survive past 65. Character counters guess; pixel measurement matches the rendering engine's own arithmetic.
What exactly is the 580px limit?
It is the observed maximum width of the clickable title link on Google desktop results, measured at 20px Arial. It is not an official published number, and Google nudges it from time to time, but it has held near 580px for years. This tool also flags titles between 535 and 580px as close, since small SERP layout changes can push those over the edge.
Does Google rewrite title tags?
Yes, often. Google rewrites titles it considers too long, too short, keyword-stuffed, or boilerplate, pulling from H1s, anchor text, or page content instead. Writing a title that fits the pixel budget and accurately describes the page is the best defense: titles that fit and match the content get rewritten far less.
Are my titles uploaded anywhere?
No. Everything is measured in your browser using the canvas text-measurement API. Nothing you paste is sent to a server, stored, or logged, so you can safely check client or pre-launch titles in bulk.
