How This Tool Works
Google does not cut titles at a fixed number of characters. It cuts them when the rendered text runs out of room in the result container, so the real limit is a pixel width. A title full of narrow letters like "i", "l" and "t" can run past 70 characters and still fit, while one packed with capitals, "M" and "W" can be cut at 50.
This preview measures your text the same way a browser draws it. In your browser it creates an off-screen canvas, sets the font to Arial at 20px for the title and 14px for the description, and calls measureText() to get the exact width. It then finds the longest run of whole words that still fits with an ellipsis added, which is how a cut-off result looks in Google.
- Title: checked against about 600px, the usual width of a desktop result.
- Description: checked against about 920px on desktop (roughly two lines) and about 680px on mobile.
- URL: turned into the breadcrumb Google shows above the title, for example

These widths are approximations based on Google's current layout. Google changes result widths and font sizes without announcing it, so leave a small margin rather than filling every last pixel.
