Does Google require a fixed meta description length?

Definition: A meta description is an HTML page summary that Google may use as the snippet, the descriptive text in a search result. As of 17 October 2026, Google specifies no fixed meta description length; displayed snippets are truncated as needed, typically to fit the device width.

Key facts

• Google's snippet documentation places no length limit on the meta description itself.
• Google's SEO Starter Guide describes a typical meta description as a succinct summary of one or two sentences.
• Google's robots meta tag specification defines max-snippet as a character limit that a publisher can set for the displayed text snippet.

Why can the displayed description vary?

Google's snippet documentation explains that snippets primarily come from page content and relate to the specific search. The same page can therefore have different snippets for different queries. Google sometimes selects the meta description when it describes the page more accurately.

Selection and truncation both affect the result: the description field's character count alone cannot specify the text displayed for every search.

What belongs in the description field?

Google's supported meta tags documentation places meta tags in the HTML <head>. Its generic description example uses the name attribute to identify the tag and the content attribute to hold the summary:

<meta name="description" content="A description of the page">

The example is a template; the actual summary describes the particular page. The same documentation explains that a content management system may provide search engine settings for meta tags instead of direct HTML editing.

The SEO Starter Guide recommends a short description unique to the page that includes its most relevant points. Its one- or two-sentence guidance gives an editorial target without prescribing a character count. Reviewing whether the summary captures the page's main content follows that guidance.

How does max-snippet differ from description length?

The robots meta tag specification defines max-snippet as a maximum number of characters in a textual search snippet. Google's example allows up to 20 characters:

<meta name="robots" content="max-snippet:20">

That setting caps the search preview; it leaves the description field's length unspecified. Without this rule, Google chooses snippet length. The rule also leaves image and video previews unaffected. A description-writing guideline and a publisher-configured snippet cap therefore serve separate purposes.
