Is Google Cutting Off Your Title?
“The Complete Guide to Search Engine Optimization for Beginners in 2025”, that’s 72 characters. Google will truncate it to something like “The Complete Guide to Search Engine Optimization for Begin…” with an ugly ellipsis. Your most important keyword (“SEO”) isn’t even in the visible part.
“Complete SEO Guide for Beginners (2025)”, 39 characters. Fits easily. Keyword is front and center. That’s the difference between a title that works and one that doesn’t.
Characters vs. Pixels, Why It’s Complicated
Google doesn’t cut at a character count. It cuts at a pixel width, around 600px on desktop. “W” is much wider than “i”, so a title full of wide characters gets truncated earlier. “Will Williams Win?” might get cut at 45 characters, while “little lit lit” could survive past 65.
A flat “9.5px per character” estimate is wrong for exactly this reason. This tool carries a real per-character advance-width map for Arial/Helvetica, the font Google renders SERP titles in, so a capital W counts as roughly 15px while a lowercase i counts as 3.5px. That gives you an actual measured width instead of a guess, plus the average pixels-per-character for your specific title.
Desktop and Mobile Cut at Different Points
Desktop SERP titles render at about 20px and clip near 600px. Mobile renders smaller (around 18px) and tolerates more total text before it clips. The same title can fit fine on a phone but get chopped on a desktop, so this tool measures both widths separately and tells you which surfaces will truncate. It then renders your title with a red marker at the exact desktop cut-off, striking through the part Google hides behind an ellipsis.
Front-Load Everything Important
If Google’s going to truncate your title, make sure it cuts the disposable part, not the critical part. Primary keyword goes first. Brand name goes last (if you include it at all). The most important differentiator should be visible even in a worst-case truncation.
Drop your primary keyword into the keyword field and the tool checks where it lands. If the keyword sits past the desktop cut-off, you get a red warning telling you to move it earlier. “Best Running Shoes for Flat Feet 2026 | Brand Name” puts the keyword upfront, so even if it gets cut after “Best Running Shoes for Flat Feet 2026 |…” the important part survives.
The Title Tag Is Your Strongest On-Page Signal
Honestly, most people underinvest in their title tags. It’s one of the strongest ranking signals Google uses to understand page relevance. And it’s also the first thing a real human reads in search results. Getting the length right is step one. Getting the keyword placement right is step two. Making it compelling enough to click is step three.
Google sometimes rewrites titles entirely, pulling from headings, anchor text, or page content. You can’t prevent it, but well-crafted titles that accurately match the page content are usually displayed as-is.
This tool is laser-focused on the title tag alone, the pixel math, the desktop and mobile cut points, and keyword placement.
