Title Tag Checker - Pixel Width & Truncation Tester

How to use this tool

1. Paste your titles. Enter one title per line in the text area.
2. Add brand suffix. Optionally enter " | Your Brand" to test the full title string.
3. Review the results. Compare the desktop 600 px guide and approximate mobile 560 px guide; each result shows character counts and an approximate cut when it overflows.

Why title pixel width matters

Google measures title width in pixels, not characters. Because different characters have different widths (e.g. "W" is much wider than "i"), a character-count limit is imprecise. Checking actual pixel width lets you push closer to the real limit without risking truncation.

Recommended limits

• Desktop: ~600 px - approximately 50–60 typical characters. This tool checks against this limit.
• Mobile: About 560 px is a single-line reference, not a fixed cutoff. The available title width depends on the device and viewport, and some mobile results wrap.

Tips for well-optimised title tags

• Front-load important keywords - truncation cuts from the right.
• Put the brand name last, separated by a pipe or dash.
• Every page on your site should have a unique title tag.
• Avoid ALL CAPS - uppercase letters are wider and reduce the number of words that fit.

How Google uses the title tag

The title tag is Google's primary source for the blue headline link displayed in search results. It directly influences click-through rate (CTR) - a compelling, relevant title drives more clicks than a keyword-stuffed or vague one.

Google may rewrite your title in search results if it determines the original is:

• Too long (truncated beyond the pixel limit).
• Too short or not descriptive enough.
• Keyword-stuffed or spammy.
• Not matching the actual content of the page.

Google rewrites titles more often than most SEOs realize - studies suggest it rewrites over 60% of titles at least partially. Writing clear, specific titles reduces the chance of being rewritten unfavorably.

Structured snippet interaction

When a page uses structured data (schema.org markup), Google may display rich results: FAQ accordions, star ratings, sitelinks, breadcrumbs, or review snippets. A well-written title tag becomes more important in these cases - the title anchors the rich result and can significantly improve overall CTR when paired with relevant structured snippets.

How this tool measures title width

The checker uses a cached browser Canvas 2D context to measure each complete title in a bold 20 px Arial-like font. A title with wide letters such as “W” can take more space than one with narrow letters such as “i”, even when both contain the same number of characters. This is why pixel width is a more useful comparison than a character limit alone.

The checker compares that measurement with a 600 px desktop guide and an approximately 560 px mobile single-line guide. The mobile reference depends on viewport and device, and search results may wrap instead of ending at one line. Font availability and Google’s rendering also differ from this local estimate, so treat the ellipsis as an approximate display cut and cross-check important pages in Search Console. Google can choose to rewrite a title.
