Most bloggers count characters instead of pixels — that is the biggest SEO title mistake. Google uses pixel width to truncate titles in search results. If your title is too wide, Google cuts it off with "..." and you lose clicks. This tool calculates exact pixel width using HTML5 Canvas API with Arial font — the same font Google uses in SERPs — so you know exactly how your title and description appear before publishing.

Step 1: Type your SEO title in the Title field. Pixel width updates instantly using Canvas API with Arial 20px — exactly how Google measures it. Step 2: Check the progress bar. Green = safe. Yellow = close to limit. Red = will be truncated. Step 3: Type your meta description. Keep it under 920px. Step 4: Watch the live Google SERP preview update as you type.

1. Higher CTR: A complete un-truncated title gets more clicks. 2. 100% Accurate: Uses Canvas measureText with exact Arial font Google uses. 3. Saves Time: No need to publish and check SERPs manually. 4. Better Rankings: Higher CTR sends positive signals to Google. 5. Completely Free: No signup, no limits, unlimited use.

The popular "60 character rule" is a myth. The letter W is almost 3× wider than i. A 55-character title full of W, M, O can be wider than a 70-character title of i, l, t. Google's desktop SERP title limit is 600 pixels and description is 920 pixels. Our Canvas-based tool measures this exactly — same method used by SEMrush, Mangools, and Ahrefs.
