How to use the SEO Title Tag Length Checker
Type or paste your title
Enter the page title exactly as it would appear in your <title> tag. This is what shows up in Google search results, browser tabs, and social-media share links. Use the title YOU control — not what Google might choose to display (Google sometimes rewrites titles, but optimising the source still matters).
Watch the live SERP preview
The preview measures your title in 20px Arial with your browser's own text engine and cuts it where a 580px budget runs out, with "…". That budget is the industry's rule of thumb for a desktop result, not a published Google limit.
Check pixel width + character count
Width matters more than character count, because letters differ: at 20px Arial an i is 4.4px and a W 18.9px, and a Chinese or Japanese character a full 20px. So 580px holds about 52 average lower-case letters but only 29 CJK characters. The character count is shown too, as the rougher check.
Write it the way Google asks
Google's guidance is descriptive, concise titles, unique to each page, without the same words repeated. If you add your site name, put it at the start or end with a delimiter such as a hyphen, colon or pipe. Put the words that matter most first, so a cut costs the least.
SEO title tags — the single highest-leverage on-page SEO element
The <title> element names a page in browser tabs and bookmarks, and it is the main source Google uses for a result's title link. Google also looks at other text on the page — its own documentation lists "the main visual title, heading elements, and other large and prominent text" — so the title you write is a strong suggestion rather than a guarantee. This tool shows how long it is and roughly where a desktop result would cut it.
There is no official length limit
Google's documentation says there is "no limit on how long a <title> element can be"; the title link "is truncated in Google Search results as needed, typically to fit the device width". The familiar 580px and 60-character figures are the industry's rules of thumb for a desktop result. They are useful for spotting a title that will almost certainly be cut, and they are not a line Google enforces. This page labels them that way.
580 pixels holds about 52 lower-case letters in Arial — and 29 Chinese characters. A character limit written for English does not travel.
Why width beats a character count
Letters are not the same width. In 20px Arial, "Illinois Title" (14 characters) is about 99px wide; "WWWWWWWWWWWWWW" (also 14) is about 264px. Chinese, Japanese and Korean characters are a full em each — 20px at this size — so a CJK title reaches the 580px rule of thumb at 29 characters. Until 30 September 2026 this tool summed a table of ASCII widths and gave every other character the width of a lower-case letter, which measured a CJK title at a little over half its real width: a title reported as fitting would be cut. It now measures with your browser's text engine, kerning included, and falls back to Helvetica/Arial metrics with CJK at one em only where it cannot.
What Google's guidance actually asks for
Descriptive, concise titles; not vague ones like "Home"; not unnecessarily long or verbose ones; no keyword stuffing — Google's example is "Foobar, foo bar, foobars, foo bars"; and, on sites where many pages share boilerplate, a site name at the beginning or end "separated from the rest of the text with a delimiter such as a hyphen, colon, or pipe". It also asks that one heading be clearly the page's main title, since several headings of equal weight give it competing candidates.
Pixels not characters, 29 CJK characters in 580px, and no official limit
Google says there is "no limit on how long a <title> element can be"; the title link is cut "as needed, typically to fit the device width".
580px for a desktop title is the industry's rule of thumb, not a published Google figure.
In 20px Arial an i is 4.4px wide and a W 18.9px — the widths come from the Helvetica metrics Arial was drawn to match.
"Illinois Title" and "WWWWWWWWWWWWWW" are both 14 characters: about 99px against about 264px.
A Chinese, Japanese or Korean character is one em wide, so 580px at 20px holds 29 of them — against about 52 average lower-case Latin letters.
Google builds title links from several sources: the <title> element, the main visual title, headings and other prominent text.
Google's own keyword-stuffing example is "Foobar, foo bar, foobars, foo bars".
For a site name, Google suggests the start or end of the title, separated by a hyphen, colon or pipe.
This tool's own sample title, "Free SEO Title Tag Length Checker — Live Preview | RECATOOLS", measures about 600px in Arial — just over the 580px rule of thumb.
Until 30 September 2026 this checker measured every non-ASCII character as a lower-case letter, reporting CJK titles at a little over half their width.
Frequently Asked Questions
-
As long as it needs to be to describe the page, and no longer. Google publishes no limit and cuts titles to fit the device. As a rule of thumb, around 580px (about 50–60 average Latin characters, or 29 CJK characters) is what fits a desktop result; the tool shows where yours would be cut.
-
Because a result is cut by the space it has, and letters take different space: in 20px Arial a
Wis over four times as wide as ani, and a CJK character is wider than any Latin letter. A character count assumes an average that many titles do not have. -
Either works. Google's guidance is simply to include a site name at the beginning or end, separated by a hyphen, colon or pipe, when many pages would otherwise look alike. If a desktop result is likely to cut the title, the end is where the cut falls.
-
Google builds title links from several sources — the <title> element, the main visual title, headings and other prominent text — and can choose another if yours is vague, stuffed with keywords, or doesn't match the page. Make the title and the main heading describe the same thing.
-
Nothing forbids them, and they count toward the width like any other character — most emoji are about as wide as a CJK character. Whether they help clicks is not something Google publishes; use them only where they say something.
-
Yes. Google's guidance asks for a descriptive title per page; identical titles give readers no way to tell results apart, and give Google no reason to prefer your wording.
-
It changes after Google recrawls the page, which depends on how often it crawls your site. Search Console's URL Inspection tool can request indexing of a single URL.
-
They are different tags.
<title>is the page title Google and browsers read;og:titleis read by social apps when the link is shared. They can differ, and a page can have both. -
No. All analysis runs in your browser via JavaScript. Open DevTools → Network and confirm zero outbound requests. Title text + analysis results stay on your device. Safe for unannounced page launches or confidential SEO experiments.
-
The Meta Description Length Checker measures the snippet under the title the same way. After you publish, Google Search Console shows the title Google actually displays and how often the result is clicked.
Method & sources
What this tool implements
- Google: "there's no limit on how long a <title> element can be"; the title link is "truncated ... as needed, typically to fit the device width". The page had called 580 px "Google's SERP cutoff".
- Until this review widths came from an ASCII-only table that gave every other character a lower-case letter's width, measuring CJK titles at little over half their width. 580 px at 20 px holds 29 CJK characters or about 52 average lower-case Latin letters.
- Removed unsourced figures: "30-40% of pages have suboptimal titles", "CTR +10-30% within a week", "+15-30% for adding a city", and an ASEAN paragraph.
