Meta Description & Title Checker
Audit page titles and meta descriptions in real time with Google SERP previews for desktop and mobile. Widths are measured in real pixels — the same way Google decides what to cut — so you see the truncation before it happens rather than guessing from a character count. Nothing you type leaves your browser.

On-page checks
- Enter a title and description to run the checks.
Title Limit
Desktop: 600px (50-60 chars)
Mobile: 805px (50-70 chars)
Description Limit
Desktop: 920px (150-160 chars)
Mobile: 680px (~120 chars)
How this measures
Rendered width in Arial — 18px title, 13px description — not a character estimate.
Title and meta description limits
Google cuts a snippet on rendered width, not on a character count. Two titles of exactly sixty characters can truncate differently: one full of capitals, m's and w's runs wide and gets cut, while a narrow one made of i's and l's survives. The character ranges below are what those pixel widths usually work out to, but the pixel figure is the one that decides.
| Element | Desktop | Mobile | Typical characters |
|---|---|---|---|
| Title tag | 600px | 805px | 50–60 |
| Meta description | 920px | 680px | 120–160 |
Note that the two run in opposite directions. A phone gives a title more room than a desktop result does, and a description considerably less. If most of your traffic is mobile, write the first 120 characters of the description as though they are the whole thing, because they usually are.
How to check a title and meta description
- Paste the URL, title and description above. The URL is only used to render the breadcrumb line in the preview; nothing is fetched and nothing is sent anywhere.
- Switch between the desktop and mobile previews. A snippet that fits on one regularly fails on the other, and checking only the desktop view is the most common way a truncated description reaches production.
- Read the pixel width rather than the character count. The measurement renders your text in the font Google uses for results — 18px for the title, 13px for the description — and measures it, so it accounts for the width of the actual letters you typed.
- Work through the on-page checks. They cover the things that are easy to get wrong and invisible once the page is live: a missing focus keyword, a description that repeats the title, a title that leads with the brand rather than the subject.
Why a pixel measurement and not a character count
Most title checkers count characters and colour the counter red past some threshold. That is a reasonable approximation and it is wrong often enough to matter. "WWW Marketing Management Workshop" and "illicit initialisation limits" are both 29 characters; rendered, the first is close to twice the width of the second. A character counter passes both or fails both. A pixel measurement tells you which one Google will actually cut.
The same reasoning applies to the mobile preview. Truncation there is not a scaled-down version of the desktop rule — it is a different width entirely, which is why the two previews here are separate rather than one view with a slider.
What this tool does not do
It does not crawl your site. Paste in what you have written, or what a page currently returns, and it measures that. If you want to pull existing titles and descriptions from a live site in bulk, that is a crawler's job — Screaming Frog and Sitebulb both export them, and both report pixel widths too. This is for the writing stage, before anything is published, and for the quick check on a single page when you are deciding whether a rewrite is worth deploying.
