Your title tag is the clickable headline in Google search results. Too long and it is cut off with an ellipsis; too short and you waste keyword space. This checker measures both the character count and an approximate pixel width, because Google truncates by pixels, not characters.
How it works
The tool counts characters and estimates rendered width using a per-character pixel table modelled on Google’s desktop SERP font (roughly 20px Arial). Narrow characters like i, l and . count around 4–5px, digits about 10px, capitals about 12px, and wide letters like m and W about 14–16px; unknown characters fall back to a 10px average. The estimate is flagged as too long when it passes the 580px desktop limit, and the character count is rated against a 30–60 character guide.
Example
The title Best Running Shoes for Beginners (2026 Guide) is 45 characters — comfortably inside the 30–60 guide — and its estimated pixel width sits under 580px, so it should display in full.
| Signal | Healthy range |
|---|---|
| Characters | 30–60 |
| Pixel width (desktop) | under ~580 px |
Pixel width is the more reliable guide because two titles of equal length can render at very different widths. Everything is calculated locally in your browser.
