How Long Should a Meta Description Be?

Google's Search Central documentation does not give a character limit for meta descriptions. It says plainly: "there's no limit on how long a meta description can be." What does get cut short is the snippet — the description text shown under your title link on the results page — and that's "truncated in Google Search results as needed, typically to fit the device width." Width, not character count, is the mechanism, which is the same rule Google applies to title tags.

That distinction matters more than the exact number most SEO tools show you, because a meta description also has a second job besides fitting a box: Google only uses it at all when it decides your description beats what it could pull from the page content on its own.

What is a snippet, and where does it come from?

Per Google's Create good titles and snippets in Search Results (Search Central documentation, checked September 2026): "A snippet is the description or summary part of search result on Google Search and other properties (for example, Google News)."

Google's default behavior is to build that snippet itself: "Snippets are automatically created from page content. Snippets are designed to emphasize and preview the page content that best relates to a user's specific search." Because of that, the same page can show a different snippet for different searches — Google is pulling whatever passage of your page text answers that particular query, not reusing one fixed block every time.

Your meta description tag is a separate input, not the only source: "Snippets are primarily created from the page content itself. However, Google sometimes uses the meta description HTML element if it might give users a more accurate description of the page than content taken directly from the page." Writing a meta description is a bid for that slot, not a promise that Google will use your exact text.

Why does a description with no length limit still get cut off?

The same way a title does. Google states it directly: "There's no limit on how long a meta description can be, but the snippet is truncated in Google Search results as needed, typically to fit the device width." Device width is measured in pixels, and different characters take up different amounts of horizontal space, which is why two descriptions with the same character count can be cut at different points, and why any fixed character number is an approximation of a pixel-width rule, not the rule itself.

If you want your description to survive truncation on a narrow screen, put the specific, decision-relevant information first — what the page actually offers, not a generic lead-in sentence that could open any page on your site.

When does Google prefer my meta description over the page content?

Google frames the meta description as a pitch, not filler: "A meta description tag generally informs and interests users with a short, relevant summary of what a particular page is about. They are like a pitch that convince the user that the page is exactly what they're looking for." It's a stronger candidate for the snippet slot when the page's own visible text doesn't already summarize itself well — a page built from scattered facts, a product spec sheet, or a long article with no upfront summary.

Google also points out that a meta description doesn't have to read like a full sentence. It can front-load structured facts a reader would otherwise have to hunt for on the page, such as an author, publish date, or price. For a page assembled from disconnected pieces — common on AI-generated sites where the design led and the copy followed — writing a description that states what the page is, plainly, can matter more than making it sound polished.

What controls does Google give me over snippet length?

Three, all stated directly on the same page:

• nosnippet — prevents Google from showing any snippet at all for the page.
• max-snippet:[number] — tells Google the maximum character length you want your snippets to be.
• data-nosnippet — an HTML attribute you can put on specific parts of a page to keep just that section out of any snippet, without blocking the whole page.

These are the only length-related levers Google documents. None of them is a target length to write toward; they're ceilings and exclusions, not a recommended minimum or maximum for the description you write.

What does Google actually recommend writing?

Straight from its own documentation:

• Write unique, page-specific descriptions. Google's words: "Identical or similar descriptions on every page of a site aren't helpful when individual pages appear in search results. Wherever possible, create descriptions that accurately describe the specific page."
• Use a site-level description on the home page or other aggregation pages, and page-level descriptions everywhere else.
• If you can't cover every page, prioritize: "at the very least, create a description for the critical URLs like your home page and popular pages."
• Avoid keyword lists. Google's own bad example is a description that's just a list of terms — "Sewing supplies, yarn, colored pencils, sewing machines, threads, bobbins, needles" — and its own better version replaces that with a sentence that actually describes the shop and adds hours and location. Google separately warns that descriptions "comprised of long strings of keywords don't give users a clear idea of the page's content, and are less likely to be displayed as a snippet" at all.

None of that is a character target. It's a specificity and uniqueness bar, applied per page.

A quick way to audit your own descriptions

1. Pull the meta description for each important page and read it next to the page's title. If they say the same thing, the description is wasted space.
2. Check whether two different pages share a description, or nearly do. If so, that's the exact problem Google names above.
3. Rewrite generic openers, such as a welcome line, into the specific fact a searcher needs — what the page covers, and any concrete detail (price, date, location) that page content might bury.
4. If you can only write a handful, do the home page first, then whichever pages actually get search traffic.
5. Preview the result. Search Console's URL Inspection tool renders roughly what Google currently uses; a raw character count in an SEO plugin is only an estimate of the pixel-width truncation point.

If you're checking this alongside every other on-page SEO item, our page-level SEO checklist for AI-generated websites walks through descriptions, titles, canonical URLs, and crawlability together rather than one at a time. If you're specifically on Squarespace, Squarespace's own SEO settings covers the exact menu path for setting a per-page description on that platform.

The bottom line

Google gives no character limit for meta descriptions, in this documentation or anywhere else in Search Central. It gives you a job description instead: write a short, accurate, page-specific summary that could win the snippet slot away from whatever Google would otherwise pull from your page text, know that the display will truncate by device width regardless of how long you write it, and use nosnippet or max-snippet if you need to control that display directly rather than guessing at a number.
