About this tool
Writing good titles and meta descriptions is one of the most important SEO tasks, yet most developers guess. This tool measures your title and description in pixels (not characters) because Google truncates based on pixel width, not character count. It shows live previews for both desktop and mobile search results, so you can optimize before publishing.
How to use the SEO Title & Meta Preview
- Paste your page title into the Title field
- Paste your meta description into the Description field
- Enter your page URL for a realistic preview
- Check the pixel counters — green means it fits, red means it will be truncated
- Compare the Desktop and Mobile previews to optimize for both
Features
- Real-time pixel measurement using canvas (accurate for Google SERP)
- Desktop and mobile previews side by side
- Green / red indicators for truncation risk
- Live character and pixel counters
- 100% client-side, no data leaves your browser
Frequently asked questions
Is this SEO tester free?
Yes. Test titles and meta descriptions instantly without registration or cost.
Does it measure characters or pixels?
It measures both. Google truncates titles and descriptions based on pixel width, so pixel measurement is more accurate than character counting.
Is it accurate for Google?
It uses Arial font at the same sizes Google renders titles (20px desktop, 18px mobile) and descriptions (14px), so the pixel widths closely match Google's SERP.
Does my data leave my browser?
No. All measurement happens locally using the HTML5 Canvas API. Your titles and descriptions are never sent to any server.
