Quick answer: A SERP snippet preview shows how your page title, URL and meta description will look in Google search results, measured in pixels rather than characters. Google truncates titles at roughly 600px (about 60 characters) and descriptions at roughly 960px (about 155 characters) on desktop. Type your title and description below to see a live preview and get a truncation warning before you publish.

How the SERP preview works
Google does not truncate search snippets by character count — it truncates by pixel width, because different letters take different amounts of space. This tool renders your title in 20px Arial and your description in 14px Arial (the fonts Google uses on desktop) and measures the real rendered width with an HTML canvas. Titles are flagged once they pass roughly 600px and descriptions once they pass roughly 960px, the points where Google typically adds an ellipsis. Character counts are shown too as a rough guide, but pixels are what actually decides whether your words get cut.
Frequently asked questions
How long should a title tag be?Aim for under 600 pixels, which is about 50 to 60 characters in most fonts. Put your most important keyword and brand near the front so they survive truncation.
How long should a meta description be?Keep it under about 960 pixels, roughly 150 to 155 characters on desktop. Mobile shows less, so front-load the key message.
Does Google always use my meta description?No. Google rewrites descriptions for roughly 60 to 70 percent of queries when it thinks another snippet matches the search better. A good description still improves click-through when it is used.
Is this SERP preview tool free?Yes, completely free and private — everything runs in your browser and nothing is sent anywhere.
