SERP Pixel Length Counter
Measure the pixel width of your meta title and description, then preview where Google may cut them off.
Runs entirely in your browser. Nothing you type is uploaded anywhere.
How to use this tool
Type or paste your meta title into the first field and your meta description into the second. As you type, the tool measures the rendered pixel width of each line and updates the bars and the live search result preview. Watch the colored bar: it stays in the accent color while you are within a safe range and turns red once the text passes the point where Google is likely to truncate it. The pixel and character readouts give you exact numbers, and the preview shows roughly how the snippet will look on a desktop result page.
How the pixel length check works
Google does not count characters when deciding whether to cut a snippet. It counts the rendered width of the text in pixels, so a title full of wide letters like W and M runs out of room sooner than one full of narrow letters like i and l. To estimate that width without a server, this meta title pixel width tool draws your text onto a hidden HTML canvas using fonts close to the ones Google renders, then reads back the exact pixel measurement. The roughly 580 pixel title limit and the description limit are approximations of the desktop display area; mobile results and Google's ongoing tweaks mean these are guidelines, not guarantees.
A real example
Take the title "Best Wireless Headphones for Working From Home in 2026". That is 53 characters, which a simple character counter would flag as too long. Measured in pixels with the canvas method it comes out around 545 px, comfortably under the 580 px limit, so it would display in full. Now compare "WWW Mega Marketing Webinar Workshop Wednesday" at only 45 characters: because it is packed with wide capital letters it measures close to 600 px and triggers the title cutoff preview warning. Same idea applies to the description: aim for under about 920 px so the full line shows instead of trailing off into an ellipsis.
Common questions
Why measure pixels instead of characters?
Google truncates search snippets based on the rendered width of the text, not the number of characters. Wide letters take more space than narrow ones, so two titles with the same character count can have very different pixel widths. A pixel length check is far more accurate than counting characters.
What is the title pixel limit?
Desktop title display tops out at roughly 580 pixels before Google adds an ellipsis. This tool warns you past that point. Treat it as a strong guideline since Google adjusts the layout over time and mobile results differ.
How long should my meta description be?
Descriptions display up to roughly 920 pixels on desktop, which usually fits around 150 to 160 characters of average-width text. Beyond that the tail gets trimmed, so keep the most important message near the front.
Will my exact title always show in search?
No. Even within the pixel limit, Google may rewrite or replace your title and description based on the query. This title cutoff preview shows the likely display when your text is used as-is, but the final snippet is up to Google.
Is my text sent anywhere?
No. The measurement and preview run entirely in your browser using a hidden canvas. Nothing you type is uploaded, stored, or shared. This is an estimate for SEO planning, not a guarantee of how Google will render the result.
