Check your title tag's character and pixel-width length against Google's SERP display limits.
This tool checks your title tag's length against the commonly published Google SERP guidelines, using both character count and an estimated pixel width.
Enter your title tag. Length, estimated pixel width, and a status appear instantly. The status is Too Long when the estimated width is above 600px, Too Short when the title is under 30 characters, and Optimal otherwise.
Titles under ~600px (roughly 50-60 characters) are commonly recommended to avoid truncation in Google's search results.
The checker reports three numbers: the character count, an estimated pixel width, and a status of Too Short, Optimal or Too Long. The rules behind the status are straightforward and worth knowing. An empty title is Too Short. A title whose estimated width is above 600 pixels is Too Long. Otherwise, a title shorter than 30 characters is Too Short, and anything else is Optimal. So the tool judges long titles by pixel width rather than by a fixed character cap, and it judges short ones by character count.
Pixel width is approximated by giving each character a width: 4 pixels for narrow characters such as i, l, I, period, comma, apostrophe, exclamation mark, the vertical bar and the space, 11 pixels for m, M and W, 8.5 for other capital letters, and 7 for everything else. This mirrors an approximate Arial-style search-result font. It is a heuristic, not a browser measurement, so a title that lands within a few percent of 600 may go either way in a real search result.
The default title, "Free Online Tools & Calculators | Plinzo Tools", has 46 characters and about 283 pixels, so it is Optimal with lots of room. A title such as "HOME" has 4 characters and 37 pixels, and is flagged Too Short. A longer, plain-language title like "Best Running Shoes for Flat Feet: Tested and Reviewed by Podiatry Fans" has 70 characters but only about 459 pixels, so the tool still says Optimal even though it is longer than the usual 60-character rule of thumb. That is where pixel-based checking earns its place. An all-caps title behaves differently: capitals average about 8.5 pixels, so roughly 70 capital letters would already reach the limit, while lowercase text with narrow letters can run considerably longer.
The 30-character floor is a practical prompt, not a rule from Google. A title that short usually says too little to distinguish the page from others, such as a bare brand name or a single generic word. If your page really does deserve a short title, for example a home page that is just the brand, you can accept the warning. The purpose is to nudge you to consider whether the title tells a searcher what the page offers.
Passing the check does not mean the title will be displayed as written. Google can replace a title with text from headings, anchor text or other parts of the page when it judges that more useful, and desktop and mobile displays differ. Length is also only one aspect of a good title. Use the tool as a guard against obvious truncation, then check the real listing after your page has been crawled and adjust if needed.
Google may truncate it with an ellipsis in search results, or rewrite it entirely -- neither is ideal for a carefully crafted title.
Because the tool judges long titles by estimated pixel width against about 600 pixels, not by a strict character limit. A title made mostly of narrow lowercase letters can be long in characters yet still fit.
Titles under 30 characters are flagged as a prompt to add helpful descriptive detail. Brand-only titles on a home page are a valid exception if you choose them intentionally.
It counts whatever text you enter. If your CMS adds a site name automatically, include that suffix in the field so you measure the full title as it will appear.
Most punctuation is counted at 7 pixels, but the vertical bar and periods, commas and apostrophes are counted as narrow at 4 pixels. The differences are small compared with letters, but they add up in long titles.
