About This Tool
A free, pixel-accurate Google SERP preview tool — no signup, no tracking.
What Is This Tool?
The Google SERP Preview Tool lets you instantly see how your page title and meta description will appear in Google search results — before you publish. Unlike simple character counters, it measures actual pixel width using the same fonts Google uses: Arial Bold 20px for desktop titles, Arial Bold 18px for mobile titles, and Arial 14px for descriptions.
Google caps title display at 600px on desktop and 496px on mobile, and meta descriptions at 920px desktop / 680px mobile. Because letters vary in width (W is much wider than i), character count alone is an unreliable guide. This tool gives you a pixel-accurate preview so you can optimize with confidence.
About the Author
This tool was built by Krunal Kanojiya, a software developer focused on building practical tools for web developers and SEO professionals. The goal was to create a fast, accurate, and completely free alternative to paid SERP preview tools — one that works correctly on both mobile and desktop.
The tool uses the HTML5 Canvas API's ctx.measureText() method with a binary search algorithm to find the exact pixel cutoff point — the same approach that rendering engines use to calculate text overflow. No backend, no tracking, no cost.
