Type a page title and a meta description and get live character and pixel-width counts against typical desktop and mobile rendering limits, plus a side-by-side SERP preview of how the result is likely to display.

Approximate rendering. Search engines may choose their own title/description sometimes; these are just the inputs you provide.
The clickable headline that appears in search results. The tool measures: characters (typical guidance: ≤60), desktop pixels (limit ≈580 px), and mobile pixels (limit ≈540 px). Beyond those pixel widths, search engines truncate the title with "…".
The 1–2 sentence summary shown under the title. Measured as: characters (typical guidance: ≤160), desktop pixels (limit ≈920 px), and mobile pixels (limit ≈980 px). Going over isn't penalized; the cut-off portion is just hidden.
The URL of the page. Shown in both desktop and mobile previews as a breadcrumb-style path under the domain. Doesn't affect any pixel measurement; it's purely for visual preview.
Side-by-side rendering of how the result looks in each layout. Desktop is wider and shows longer titles before truncation. Mobile is narrower for titles but slightly wider for descriptions. Most search traffic now happens on mobile.
Visual indicator of how close you are to the truncation limit. Green = comfortable, yellow = approaching limit, red = over the limit and being truncated.
Two things for each field: character count (a count of code points) and pixel width (how wide the text is when rendered in search-result font). Pixel width matters because search engines truncate by pixels, not characters; wide characters like "W" or "M" take more space than narrow ones like "i" or "l".
Measurements of current desktop and mobile search-result layouts. Title desktop ≈ 580 px, title mobile ≈ 540 px, description desktop ≈ 920 px, description mobile ≈ 980 px. Search engines can adjust these and may also rewrite titles or descriptions of their own choosing; these numbers are the truncation thresholds, not a guarantee.
Titles are measured in Arial 20px and descriptions in Arial 14px, the closest publicly observable match to current search-result rendering. If search engines change their SERP font, measurements will drift slightly.
Different characters have different widths in proportional fonts. "iiii" is much narrower than "MMMM" even though both are four characters. Pixel width is the more accurate measure of whether your title will actually be truncated.
No. Pixel width is measured locally using HTML Canvas. Nothing about your title, description, or URL leaves your browser.
