Aim for a meta description of 120 to 155 characters, with the most important words in the first 120. Google has no limit on length, but it cuts the snippet to fit the screen, and in the 269 Google snippets I measured for this post, 90% were 161 characters or shorter.
That’s the short answer. The longer one is more interesting, because the same test showed something most length guides skip: Google ignored my own meta descriptions on every result where this blog appeared. I’ll show you the numbers and what I’m changing because of them.
What Google says about meta description length
Google’s guide to controlling your snippets is clear on this: “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.”
So any number you read, including mine, is about what fits on the screen, not about a rule. Google measures by width, not by characters. A description full of wide letters gets cut earlier than one with narrow letters, which is why every character count is an approximation.
The same guide also says “Google primarily uses the content on the page to automatically determine the appropriate snippet.” The meta description is a suggestion. Google uses it when it thinks it describes the page better than any passage it could pull from the text.
What I measured in 269 Google snippets
I wanted real numbers instead of repeating the usual 155-160 rule, so on October 13, 2026 I pulled the US Google results for 10 queries where this blog ranks in the top 30. I used DataForSEO’s live SERP data (desktop) and kept the first 30 organic results of each query.
That gave me 269 results with a snippet. Before counting, I removed the date that Google adds at the start of some snippets and the “Read more” link at the end, so the numbers reflect only the description text.
| Measure | Characters |
|---|---|
| Shortest 10% of snippets | 118 or fewer |
| Median snippet | 144 |
| Longest 25% start at | 148 |
| 90% of snippets were at most | 161 |
| Longest snippet in the sample | 169 |
Two more things stood out. 58% of the snippets ended with “…”, which means Google cut them. And 38% started with a date, like “Sep 19, 2026 —”. That date takes about 15 characters of the space you’d expect your description to use, so on blog posts the visible part of your text is often shorter than the numbers above.
This was a small sample on one device and one country, so treat it as a check on the usual advice, not as a new rule. It does line up with it: write for about 150 characters and you’ll be inside what Google showed in nine out of ten cases.
Google rewrote all 4 of my descriptions
Here is the part I didn’t expect. This blog appeared in 4 of the 10 results pages, and in all 4 Google showed text from the page instead of my meta description.
Take the query “worst social media app”. My meta description talks about “the 6 worst social media platforms of 2026” and lists TikTok, X and Facebook. Google showed a sentence from the article about which apps are worst for children and teens, because that’s what the query seems to be about.
For “gaming niches”, Google showed a sentence from the body of the post that defines what the gaming niche covers. My meta description talked about market size and search demand. The definition was the better match for someone typing “gaming niches”, and Google knew it.
What did I learn? A meta description that summarizes the page is not enough when the query asks a narrower question. Google looks for the passage that answers the query. That means the first lines of your content matter as much as the meta tag, and probably more. I explain this in more depth in my guide to search intent.
How long should your meta description be?
| Case | Length I aim for | Why |
|---|---|---|
| Blog posts | 120-150 characters | Google often adds a date at the start |
| Product and service pages | 140-155 characters | No date, more room for price or benefit |
| Homepage | 140-155 characters | Brand plus what you do and for whom |
| Pages that rank for many different queries | Write it, but expect rewrites | Google picks the passage that fits each query |
Why not go to 160 every time? Because the longer it is, the more likely the end gets cut, and the end is where people tend to put the call to action. Put the useful part first and let the tail be optional.
How to write a meta description Google might actually use
- Answer the main query in the first sentence, in plain words. If someone searches “meta description length”, the description should include a length.
- Put the specific detail early: a number, a price, a year, a result. Specifics get noticed in a list of ten similar snippets.
- Write one for each page. Google’s guide asks for descriptions that “accurately describe the specific page”, and duplicates are easy for it to ignore.
- Describe what’s really on the page. If the description promises something the page doesn’t deliver, Google is more likely to replace it, and readers who click will leave.
- Skip keyword lists. Google’s guide warns that “meta descriptions comprised of long strings of keywords don’t give users a clear idea of the page’s content.”
- Make the first paragraph of the page a good snippet too. When Google rewrites, that’s often where it looks.
What the meta descriptions on this blog look like
I measured my own as well. All 246 published posts on this blog have a custom meta description, and the last batch of rewrites was in May 2026. The median is 136 characters, 219 of them fall between 120 and 160, 26 are shorter than 120 and only 1 is longer than 160.
On paper that’s a tidy set. In practice the snippet test above shows that length was never the problem. The descriptions summarized each post well, but they didn’t answer the narrower questions people were actually typing. That’s what I’m changing as I update older posts: the first lines of each post and the description now answer the main query directly, as I describe in my SEO checklist for bloggers. The rest of the process is in my niche blogging guide.
Does meta description length affect rankings?
No. Google said it plainly back in 2009 on its Search Central blog: “Even though we sometimes use the description meta tag for the snippets we show, we still don’t use the description meta tag in our ranking.” (source)
What the description can change is how many people click. A snippet that answers the query clearly gets more of the clicks your position already earns. That’s why it’s worth the five minutes per page, even knowing that Google will rewrite many of them.
Meta description length FAQ
Is 160 characters too long for a meta description?
It’s at the top of what Google showed in my test, where 90% of snippets were 161 characters or shorter. It’s not wrong, but the last words are likely to be cut, especially on blog posts where Google adds a date.
What happens if my meta description is too long?
Google cuts it with “…” where it runs out of space. Nothing breaks and there’s no penalty. You just lose the end of the sentence, so keep the important part at the start.
What happens if my meta description is too short?
Google may show it as it is, or it may pull extra text from the page to fill the space. A very short description often means Google writes its own snippet.
Why does Google not show my meta description?
Because it decided another passage on your page answers the query better. It happened to all 4 of my results in the test above. Make the description match the main query and make sure the first lines of the page answer it too.
How many characters should a meta description have for mobile?
Google truncates “to fit the device width”, so mobile usually shows less. My test used desktop results. If most of your traffic is mobile, keep the key information in the first 120 characters.
Open Search Console, pick your five pages with the most impressions, search their main query and look at the snippet Google shows. If it isn’t your description, rewrite the first lines of the page before you rewrite the meta tag.
