Character Limit Checker › Title tag length

SEO title tag length checker

Two things go wrong with a title in search, and only one of them is length. This page measures the pixel width that decides where the title link is trimmed, then runs your title against the rewrite cases Google publishes.

Three titles that fit and still get rewritten:

Characters, bytes and pixels

The character count is the number every other checker gives you. The pixel width is the one that decides whether the title link is trimmed, because a title is drawn in a proportional font and W is roughly four times the width of i.

Where the title link is trimmed

Paste a title above and this fills in.

Screen Budget Your width Verdict Characters that survive

Widths are measured in your browser with canvas.measureText in 18px Arial, the size a third party measurement found in use for the title line. Google publishes no pixel figure and the published third party ones disagree, especially on mobile, so both budgets are editable fields rather than constants.

Rewrite risk, which is a different question from length

Trimming and rewriting are two separate things. A trimmed title is your text with the end cut off. A rewritten one is not your text at all: Google builds the title link from headings, anchor text or structured data instead. Google documents seven cases where it does that, and the checks below cover the five a page can test from the title alone plus two more once you paste the H1.

A green row here is not a promise. Google rewrites title links whenever it judges another string more useful for the query, and the cases below are the ones it has written down, not the whole rule.

Two different failures with the same symptom

A title that does not look right in search has failed in one of two ways, and they have different fixes. Either the text is yours and stops early, which is a width problem, or the text is not yours at all, which is a rewrite. Length checkers usually only measure the first one, so a title that is comfortably under 60 characters and still shows up wrong looks like a mystery.

The width half

Google states that it truncates snippets to fit the device width, and the title line follows the same logic in a larger font. Sixty characters is the familiar rule of thumb because sixty average English characters are roughly 600 pixels of 18px Arial. Load it with capitals or with wide letters and the same sixty characters overflow; write it in narrow ones and seventy will fit. This page measures the string you actually wrote rather than counting it.

The rewrite half, which is documented

Google's title link documentation lists what it draws a title from: the title element, the main visual title, headings such as h1, og:title, prominent styled text, anchor text pointing at the page and WebSite structured data. It then lists the cases where the title element loses to one of those: half-empty titles, obsolete titles, inaccurate titles, micro-boilerplate repeated across similar pages, no clear main title, a writing system or language that does not match the page, and duplication of the site name.

None of those cases is about length. A 45 character title made of three category names chained with pipes is short, well inside every budget, and a textbook micro-boilerplate case. That is why this page runs the checks above next to the ruler.

What the H1 field is for

Two of the documented cases, an inaccurate title and a language mismatch, can only be tested against something else on the page. Pasting the H1 gives the checks a second string to compare with: how much of the title's vocabulary a reader actually sees on the page, and whether the two are written in the same script. Nothing is uploaded to do it, the comparison runs in the page like everything else here.

Where each number comes from

The rewrite cases and the list of sources Google draws a title from are quoted from Google's own title link documentation. The pixel budgets are not Google's, because Google publishes none, and the mobile figure is the weakest number on this page: it is marked as such and left editable.

Questions people actually ask

How long should a title tag be in characters?

There is no published character limit. Sixty is the usual advice because sixty average English characters come out near 600 pixels of 18px Arial, which is where desktop results have been measured to trim. Write in capitals or in wide letters and you overflow well before sixty; write in narrow ones and seventy survives. Measure the string, not the count, which is what the ruler on this page does.

Google replaced my title even though it fits. Why?

Because trimming and rewriting are different mechanisms. Google builds the title link from the title element, the visible main title, headings, og:title, prominent text, anchor text and WebSite structured data, and it documents seven cases where your title element loses: half-empty, obsolete, inaccurate, micro-boilerplate, no clear main title, a writing system that does not match the page, and a duplicated site name. None of them is about length. The rewrite risk panel on this page runs those cases against your title.

Is this the same tool as the meta description page here?

It shares the measuring code and nothing else. The description page measures 13px Arial against a wide budget and explains Google's statement that descriptions have no length limit. This one measures 18px Arial against a narrower budget and spends most of the page on title rewriting, which does not apply to descriptions at all: Google documents the rewrite cases for titles on a separate page from the snippet documentation.
