Quick Takeaways
Meta description length should land between 150 and 160 characters, but that number is a convention, not a Google rule. Google publishes no character limit and truncates snippets to fit the device width instead. Front-load your point in the first 120 characters, since Google often rewrites the rest.
Meta description length is the one SEO number everyone quotes and almost nobody sources. The rule of thumb says 150 to 160 characters. Google says something different.
No limit exists on how long a meta description can be, per Google's own documentation on writing meta descriptions. Snippets get truncated to fit the device width instead. No magic number appears anywhere in its guidance.
So the 150 to 160 rule survives for a practical reason, not an official one. Here's where it comes from, when it matters, and why Google may rewrite your description no matter how carefully you count it.

What Is the Ideal Meta Description Length?
Write between 150 and 160 characters, including spaces. That range gives your full description the best chance of displaying on desktop without being cut off.
Put your core message in the first 120 characters, though. Mobile results show less text, and a rewritten snippet may keep only your opening clause.
Under 80 characters is usually too thin. A short description gives Google little to work with, which makes it more likely to write its own from your page content. Complete beats brief here.
Google Has No Meta Description Character Limit
This is where most advice quietly misleads you. Google states plainly that no limit exists on meta description length, and that snippets are truncated as needed to fit the device width.
Truncation happens by pixel width, not character count. A description packed with wide letters like W and M runs out of room sooner than one full of narrow letters. The character counts can be identical.
Length isn't a ranking factor either. A page doesn't rank higher because its description hits 155 characters, so the real payoff is click-through rate rather than position.
Why 150 to 160 Characters Still Works
If Google publishes no limit, why does the convention persist? Because at typical desktop rendering, roughly 155 to 160 characters of Latin text is what fits before truncation. The rule is a decent proxy for the pixel reality.
It's also a useful discipline. A 155-character cap forces you to say one clear thing instead of three vague ones, and clarity is what earns the click.
Treat it as a target zone, not a pass or fail test. Landing at 148 or 163 characters won't hurt your rankings, and a description that reads well beats one that hits a number exactly.
The range shifts anyway. Google has shown much longer snippets in the past, then pulled them back again. It also displays a date alongside some results, which steals room from your text.
Design for the message, not the measurement. If your point only lands at 158 characters, a reader on a phone may never reach it.

Google Rewrites Descriptions More Than You Think
Here's the part that frustrates writers. Google primarily builds snippets from the content on your page. It uses your meta description only when that describes the page better.
That means Google may ignore what you wrote. It swaps in a passage matching the searcher's specific query, so the same page can show different snippets for different searches.
You can lower the odds of a rewrite. Descriptions stuffed with keyword strings are less likely to be displayed, and duplicate descriptions across pages are less helpful when individual pages surface.
One control does exist. The max-snippet rule in the robots meta tag caps how much text Google may show, as documented in Google's robots meta tag specifications. It limits length rather than forcing your wording.
Write a Description Google Will Actually Use
Use a simple structure: what the page covers, why it matters, and what the reader gets. Write it as a sentence a human would say, not a keyword list.
Compare these two, with real character counts:
Weak, strong, and over-length descriptions with their real counts.
That weak version wastes 104 characters saying nothing specific. Compare the strong one, which delivers the answer, the number, and the benefit inside 153.
Write a unique description for every page. Google suggests site-level descriptions for your home page and page-level descriptions everywhere else.
Descriptions don't have to be prose, either. Google notes that product pages can list price and manufacturer, while blog posts can carry an author or a date. That often says more than a sentence would.
The same 153-character description on desktop, then cut on mobile.
How to Check Your Meta Description Length Free
Counting characters in your head doesn't work, and a CMS field that silently accepts 300 characters won't warn you. UltraWordCounter counts as you type, running in your browser with nothing uploaded and nothing saved.
For descriptions specifically, the free meta description character counter tracks your text against the 150 to 160 target and shows exactly where 120 characters falls. You'll see whether your point survives a mobile truncation before you publish.
The workflow takes under a minute. Draft your description, watch the counter, trim until the number lands in range, then confirm the first 120 characters carry the whole message.
Everything runs free up to 800 words per session, which covers a batch of descriptions. Questions about how the counter treats spaces and symbols are answered on the UltraWordCounter FAQ page.
If you write descriptions for hundreds of pages, you'll hit the session cap. The Pro plan removes the 800-word limit for $19 a month, or $12 if you pay annually ($144/year), with a 7-day free trial. If you publish a post a week, stay free; that's fine with us.

Frequently Asked Questions
What is the ideal meta description length?
Aim for 150 to 160 characters including spaces, which usually displays in full on desktop. Front-load your core message inside the first 120 characters, because mobile results show less. Google publishes no official limit, so treat the range as a practical target rather than a hard rule.
Does Google have a meta description character limit?
No, Google states there's no limit on meta description length, and truncates snippets as needed to fit the device width. Truncation depends on pixel width rather than character count, so wide letters eat space faster. The familiar 160-character figure is a convention, not an official rule.
Is meta description length a ranking factor?
No, description length doesn't affect where your page ranks. Google uses it to help build the snippet shown in results, not to score the page. A well-written description improves click-through rate, and that traffic matters, but hitting exactly 155 characters earns you nothing.
Why does Google rewrite my meta description?
Google builds snippets primarily from your page content, using your description only when it describes the page better. It also swaps in passages matching the searcher's query, so different searches show different snippets. Keyword-stuffed or duplicated descriptions are less likely to be used.
Can a meta description be too short?
Yes, in practice. A description under 80 characters gives Google little to work with, which raises the chance it writes its own from your page content. Short is fine when it's complete, but a fragment that fails to explain the page tends to get replaced.
Conclusion
Meta description length is a display constraint, not a ranking lever. Google publishes no character limit and truncates by device width, so the 150 to 160 rule is a useful proxy rather than a law. Write for the click and the number takes care of itself.
Count it before you publish anyway. Paste your description into UltraWordCounter, confirm it lands in range, and check that the first 120 characters carry your point. Try it free and stop guessing where Google will cut you off.
