SERP Snippet Preview
See a title and meta description as a search snippet: character and word counts, an estimated title width from font metrics, and where your limits cut them.
A snippet mock-up with breadcrumb, the title’s estimated pixel width and the description’s length against limits you set, both shown truncated where they would be — with the estimate’s basis stated.
Example: "Free Concrete Calculator — Slabs, Footings and Bags with the Working Shown" measures about 703 px at 20 px Arial, so a 600 px limit cuts it after "with the"; a 171-char description is cut at 160.
A width estimate
with its basis on show.
How the pixel width is estimated, what the limits are, and what search engines do anyway.
The estimate
Each character of the title is looked up in the advance-width table of Adobe’s Helvetica AFM (Arial shares these metrics), summed and scaled to the font size you set — 20 px by default. Characters outside the table count as an average letter. The result is an estimate for a sans-serif face, not a measurement of any search engine’s rendering.
The limits
The title cut-off in pixels and the description cut-off in characters are fields, prefilled with the sample figures that SEO guides such as Moz publish (about 600 px and 155–160 characters). They are samples, not rules: change them to whatever your own observations say.
What engines do anyway
Search engines rewrite titles and descriptions, pick text from the page, and truncate by device and layout. Treat the mock-up as a length check on your own copy, not a prediction of the snippet. The breadcrumb is built from the URL you paste; nothing is fetched. Nothing leaves the browser; the same four anonymous usage counts as the rest of the site apply.
SOURCES
- Adobe Helvetica AFM advance widths (Arial is metric-compatible) summed per character at the font size entered; pixel and character limits are user fields prefilled as labelled samples
- Moz, Title Tag guide (≈600 px sample limit) and Meta Description guide (≈155–160 characters)
