SERP Snippet Preview

Type a title and meta description to see how the snippet will look in Google search results — and exactly where it gets truncated. Length is measured in pixels at the font sizes Google renders, because Google cuts snippets by width, not by character count.

Switch between desktop and mobile: the two have different width limits, and a title that fits one often does not fit the other.

How to use it

  1. 1

    Enter the page URL

    The URL only shapes the breadcrumb line shown above the title — nothing is fetched or sent anywhere.

  2. 2

    Type your title and description

    The preview updates as you type. The width bar turns amber as you approach the limit and red once the text will be cut.

  3. 3

    Check both devices

    Toggle desktop and mobile. Aim to fit both; if you cannot, favour the device that brings you more traffic.

How accurate is this preview?

Widths are measured with the browser's own text metrics at the sizes Google uses — 20px for desktop titles, 14px for descriptions — which is far closer to reality than counting characters. Wide letters like W and M eat space that i and l do not.

Google rewrites titles and descriptions when it judges its own version a better match for the query — studies put that at roughly half of all snippets. A preview shows your intended text, not a guarantee of what will be displayed.

Everything runs in your browser. Nothing you type is sent to a server or stored.

Frequently asked questions

How long should a title tag be?
Around 580 pixels on desktop and 920 on mobile, which usually lands between 50 and 60 characters. Character counts are a rule of thumb; the pixel bar in this tool is the real constraint.
How long should a meta description be?
About 920 pixels on desktop, roughly 150-160 characters. Mobile shows less. Put the useful part first so it survives truncation.
Does the meta description affect rankings?
Not directly. It affects whether someone clicks your result, which is the whole point of writing a good one.
