Pixel-accurate Google SERP preview.
Paste your title, description, and URL. See how Google renders the snippet on desktop and mobile — and get a warning the moment your title or meta description gets truncated.
How to use the SERP Simulator.
- Step 1Paste your URL
Drop the canonical URL of the page you want to preview.
- Step 2Paste the title tag
The simulator measures pixel width using Google's render font (Arial 20px desktop, 16px mobile).
- Step 3Paste the meta description
Watch the live counter — green is safe, yellow is borderline, red means Google will truncate it.
- Step 4Copy the meta tags
Click "Copy as HTML" and paste the title and description directly into your <head>.
Questions about the SERP Simulator.
Google truncates titles based on rendered pixel width, not characters. A title of 60 'i' characters fits, but 60 'W' characters won't. The desktop limit is roughly 580px and mobile is around 560px.
Arial-equivalent at 20px for desktop titles and 14px for descriptions. Mobile titles render at 16px. We approximate this with HTML5 Canvas measureText, which is what most SERP tools (including Yoast and Mangools) use under the hood.
Google rewrites titles in roughly 60% of SERPs based on query intent and on-page signals. To minimize rewrites: keep titles under the pixel limit, match user intent, avoid clickbait, and ensure your H1 closely matches the title tag.
No. It runs entirely in your browser — title, description, and URL never leave your device.
