Google SERP Preview — Snippet Truncation Simulator
DeveloperA SERP preview simulates how a page title, URL, and meta description will appear in Google search results, marking truncation by rendered pixel width on desktop and mobile layouts.
What is it
Google truncates result titles and descriptions by available pixel width, not by character count. This tool measures the rendered pixel width of your title and description with a browser canvas, marks the approximate cutoff, and draws desktop and mobile previews. The pixel limits are industry-standard approximations rather than official Google values, and the real display can vary by device, language, and query.
How to use
- 1Enter the title, URL, and meta description.
- 2Switch between the desktop and mobile tabs.
- 3Adjust the copy using the pixel gauges and the truncation marker in the preview.
Reference
| Element | Desktop limit (approx.) | Mobile limit (approx.) |
|---|---|---|
| title | ≈ 580px | ≈ 920px |
| meta description | ≈ 990px | ≈ 1,300px |

FAQ
Is my title or description sent to a server?
No. Pixel measurement and the preview both run in your browser; nothing is sent to a server.
Are the pixel limits exact?
No. Google does not publish official limits; the values here are common approximations used by SERP tools, and actual truncation varies with device and font rendering.
Will Google always show my title as written?
Not always. Google documents that it may rewrite title links based on the query and page content.
