Meta Description & Title Checker

Character count isn't the whole story — check pixel width too. A title can pass the character check and still get sliced off in the search results.

Title

0characters

Commonly-cited guidance: aim for 50–60 characters, treat 60–70 as a warning zone, and expect truncation beyond that. This isn't an official Google rule — Google truncates by rendered pixel width, not character count.

Desktop 0px
Mobile 0px

Estimated from average Arial/Helvetica character widths at ~20px (desktop) and ~18px (mobile) — the sizes Google commonly renders titles at, compared against typical ~600px desktop and ~340px mobile result widths. This is an estimate: Google publishes no exact pixel threshold, and real rendering varies by device, browser, and font substitution.

Meta description

0characters

Commonly-cited guidance: aim for 120–155 characters, treat 155–160 as a warning zone, and expect truncation beyond that. Again, this is a rule of thumb, not an official limit — and Google frequently rewrites descriptions entirely.

Mobile 0px

This is a rough estimate of total text width, not a pass/fail check — descriptions wrap across two lines rather than truncating on one, so whether it actually fits depends on where it wraps. The live SERP preview below shows the real result.

Live SERP preview

This is the real test. Rendered live in your browser at realistic desktop and mobile widths, so you can see exactly where each one gets cut — a case character count alone can't catch.

Title Description

Meta descriptions are not a Google ranking factor — Google confirmed this directly in April 2022. Checking for your keyword here isn't about rankings: it's about matching what a searcher actually typed, so the snippet reads as relevant, and getting the term bolded in the result — which can help click-through even though it does nothing for where you rank.

FAQ

How long should a meta description be?

Most SEO tools, this one included, suggest roughly 120–155 characters as a starting point. But the character count is a proxy, not the real constraint — Google truncates based on how many pixels the rendered text takes up in the search result container, not how many characters it contains. 155 characters of narrow letters (i, l, t, f) can fit fine; 130 characters loaded with capitals and wide letters (W, M, O) can run past the edge. Use the character range as a rough guide, then check the pixel estimate and the live preview above before you publish.

Does meta description length affect SEO rankings?

No. Google confirmed in April 2022 that the meta description tag is not used as a ranking signal — and in fact Google frequently rewrites or replaces the description you write with text pulled from the page, regardless of length. What description length does affect is how much of your snippet is visible before it's cut off, which can influence whether someone clicks. That's a click-through consideration, not a rankings one.

Why did my meta description get cut off even though it was under the character limit?

Because the 155–160 character guideline is an average, and truncation happens by pixel width in the font Google renders — not by a character count at all. A description with a lot of wide characters (capital letters, "M", "W", numerals) or written in a language whose glyphs render wider than average English text can hit the pixel limit well before 155 characters. That's the gap this tool is built to catch: it's entirely possible to pass the character check above and still see the ellipsis (…) show up in the pixel estimate or the live preview.

Does Google ever shorten or rewrite a title, even if it would have fit?

Yes — and this is separate from pixel-width truncation. Truncation cuts a title mid-string with an ellipsis when it exceeds the pixel limit. Rewriting is different: Google can display a shorter version of a perfectly fitting title, choosing a clean subset — often stopping at a natural break like a pipe or colon — rather than showing the whole thing. A title well under the pixel limit can still appear shortened in real results. This tool checks length and pixel width, which tells you whether truncation would happen — it can't predict whether Google chooses to rewrite the title instead, since that decision isn't based on length at all.

All thresholds above are commonly-cited SEO conventions and pixel-width estimates, not values published or guaranteed by Google. Nothing here is sent anywhere — everything runs locally in your browser.
