Meta Descriptions: We Wrote 186 to a Limit Google Says Does Not Exist

Every one of the 186 posts on this blog carries a hand-written meta description. Not one is shorter than 129 characters or longer than 160. The whole corpus sits inside a band of 32 possible lengths, which is a very precise target to hit 186 times for a limit that Google's own documentation says does not exist.

A meta description is the <meta name="description"> element in a page's head: a short summary Google may use as the snippet under your result. It is not a field Google is obliged to use, and Google's snippet documentation describes it only as one input to the snippet, never as a ranking input. What follows is what we found when we measured our own habit against that documentation and against the pages currently ranking for this query.

What we measured, and how

Two populations, both read on 3 November 2026 by the agent that wrote this post. The first is this blog: all 186 published posts, with the stored seoDescription and its length pulled straight from the CMS. The second is the competition: the eight organic results in the US top ten for "meta description" according to Ahrefs' SERP index, which captured that results page on 30 October 2026, with each page's actual meta description fetched from the live HTML on the day we read it.

The documentation quoted throughout is Google's own snippet guidance, last updated 20 April 2026. Where we quote it, we quote the sentence rather than paraphrasing it, because the paraphrase is how the folklore got started. Every quotation below links to the page it came from.

Google publishes zero character limits, and says so in one sentence

The tools that turn your description bar red past a fixed character count are enforcing a convention, not a specification. Our own SEO scorer does it too, and scores 120 to 160 as good. Google's wording is unambiguous:

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.

Read the second half carefully, because it is the part that matters. Truncation is not a character count. It is a function of the display width of the device the searcher is holding, which means there is no single number that is correct for every reader of the same page. A description that survives intact on a desktop result will be cut on a phone, and no amount of trimming to 155 changes that.

There is a second sentence worth having in front of you, from the same page:

Google primarily uses the content on the page to automatically determine the appropriate snippet. We may also use descriptive information in the meta description element when it describes the page better than other parts of the content.

Your meta description is a candidate, not a setting. Google picks between it and the page body, per query.

Our 186 descriptions stop at 160, because our own editor says to

Here is what we produced, against what the pages ranking for this query produced.

Measure	Our 186 posts	The 7 ranking pages with a description
Shortest	129	105
Longest	160	154
Mean	148.6	139.4
Median	149	145
Duplicate descriptions	0	not measured

The mean is 148.6 characters and the median is 149, and the cause is not mysterious. The description field in our own CMS shows a hint asking for 120 to 160 characters, and the writing prompts that ship with the same admin tooling ask for the same range. That hint cites no source. It has been in the editor since 19 July 2026, eight days before the oldest post in this corpus was published, and all 186 descriptions sit inside it: nothing under 120, nothing over 160, and 23 of them in the last five characters of the range.

Length	Posts	Share of 186
Under 120 characters	0	0%
120 to 155	163	88%
156 to 160	23	12%
Over 160	0	0%

One number here is genuinely good: zero duplicates. All 186 descriptions are unique, which is the part of Google's snippet documentation that is a real instruction rather than an invented limit.

Identical or similar descriptions on every page of a site aren't helpful when individual pages appear in search results.

That one we got right.

The 7 ranking pages with a description average 139.4 characters, and the 8th has none

If 155 characters were the thing that mattered, the pages winning this query would be clustered at it. They are not. Seven of the eight ship a meta description, and they run from 105 to 154 characters. Not one reaches 156. The table is ordered by length rather than by position.

Position	Page	Meta description length
5	semrush.com/blog/meta-description/	105
4	yoast.com/meta-descriptions/	129
7	seobility.net/en/wiki/Meta_Description	140
2	developers.google.com/search/docs/appearance/snippet	145
6	moz.com/learn/seo/meta-description	151
9	mailchimp.com/resources/what-is-a-meta-description-plus-examples/	152
8	university.webflow.com/videos/seo-title-meta-description	154
10	infomedia.com/podcast/what-is-a-meta-description/	no meta description element

Semrush ships 105 characters on its own page about meta descriptions, the shortest of the seven and 55 characters under the 160 our own editor asks for. Its text opens by telling you that the thing you are reading is itself a meta description. Moz, at 151 characters, opens the same way. The two pages in the sample that demonstrate what they define sit 46 characters apart, which is the clearest evidence here that the number is not the thing being optimised.

And the page at position 10 has no meta description element at all. We checked twice, once with PowerShell's Invoke-WebRequest and once with curl piped to grep, and name="description" appears zero times in the served HTML. It carries an og:description of 414 characters instead. Google's snippet documentation names only the meta name="description" element as a description source; it does not mention Open Graph either way. A page with nothing in the field Google reads is ranking on page one for the query "meta description".

What the number should be instead

Stop counting to 155 and count to the sentence. The useful constraint is not a character budget, it is whether the description reads as a complete thought when it is cut, because on some device it will be cut.

1. Put the thing that distinguishes this page from the other results in the opening clause, because truncation cuts from the end and the opening is what survives it.
2. Let the rest of the sentence run as long as it needs to. There is no documented penalty at 161 characters, because there is no documented limit.
3. Make it unique across your site. This is the only length-adjacent instruction Google actually gives.
4. Write a description, not a keyword list. Google's wording, on the same page: "Keep in mind that meta 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."
5. Expect it to be ignored. Google chooses per query between your text and the page body, so write the page body to be quotable too.

The same logic applies one element up. Our piece on title tags works through why Google rewrites titles and how to tell when yours was replaced. It also carries a table row calling 140 to 160 characters the practical length for a meta description, and our on-page checklist gives the same range in a paragraph. Both predate this measurement, and this post supersedes both.

What this does not prove

This measures lengths, not outcomes. Nothing here shows that a longer description earns more clicks, or that the page with no description ranks where it does because of that absence rather than in spite of it. Those are different studies and they need click data we do not have for other people's pages.

• One query, eight pages. The competitor sample is a single SERP in a single country on a single day. It establishes that short descriptions and one missing description both rank here. It does not establish a norm.
• Character count is not pixel width. We counted characters because that is what the tools count. Truncation follows rendered width, so a description of wide characters is cut earlier than a narrow one of the same length.
• We did not check which of these descriptions Google actually displays. That would need per-query snippet capture, and Google's spam policies treat automated querying of Search without permission as machine-generated traffic.

The honest conclusion about our own 186 is narrow: we wrote every one of them to a hint in our own editor that cites no source, and nobody ever asked where the number came from. The descriptions are unique and specific, which is the part that was always real.
