Meta Description Preview — Desktop (160) & Mobile (120) Length

Desktop and mobile show different cutoff points

Google displays your meta description at around 160 characters on desktop and 120 characters on mobile. The same 140-character description fits entirely on desktop but gets truncated with an ellipsis on mobile. Writing for the mobile viewport is the realistic constraint — few users scroll beyond the cut-off.

Character count is a rough proxy for pixel width

This tool counts characters because that's fast and simple. In reality, Google truncates based on rendered pixel width, not character count. A description full of W and M characters (each ~16 pixels) will hit the cut-off sooner than one full of i and l (each ~4 pixels). At 120 characters, a narrow description may render completely while a wide one spills over. This tool's character gauge is a useful approximation, but pixel width is where Google actually draws the line.

The sweet spot balances coverage and impact

The ideal length hovers around 155–160 characters — long enough to convey your page's value without leaving blank space on desktop, yet short enough to breathe on mobile without truncation. Shorter descriptions (100–130 chars) always fit but may feel thin. Descriptions over 160 characters truncate on desktop and are pointless.

This tool previews, it does not verify

Enter a description, see how it renders in a SERP-style card, and watch the character meter flag when you exceed desktop or mobile limits. The preview is live — no lag. It does not fetch your actual page from the web, check whether you've deployed the description tag, or account for variable font widths across browsers. Use it as a draft aid, not a guarantee of how Google will render your live page. For the full result including title and URL, see the SERP Preview Tool.
