Meta description too long: how to trim it so the point survives
A meta description is too long when it runs past 160 characters, beyond what Google usually displays before cutting it off with an ellipsis. Trim it to the sentence or two that matters, with the most useful information in the first 120 characters.
A long description is not penalized, and Google may even show different parts of it for different queries. The real risk is that the useful part sits after the cut, and that long, rambling descriptions are the kind Google tends to replace with its own snippet.
What it looks like in the HTML
Before
<meta name="description" content="Welcome to Bean Notes, the home of coffee lovers everywhere. In this article we will be taking a detailed look at everything you could ever want to know about making cold brew coffee at home, including ratios, grind size, steeping time and much more.">
After
<meta name="description" content="Cold brew needs a coarse grind, a 1:8 ratio and 12 to 18 hours in the fridge. Here is the method and how to fix bitter or weak batches.">
Why it matters
Google truncates descriptions by pixel width, typically around 150 to 160 characters on desktop and fewer on mobile. Whatever falls after that point is invisible to the searcher. If your description opens with a welcome message and gets to the point in the second sentence, the visible part is the welcome message.
Long descriptions often try to cover every angle of a page, which makes them vague. Google rewrites descriptions it considers a poor match for the query, so a focused description written for the page's main query is more likely to survive than a paragraph that lists everything.
Common WordPress causes
- The excerpt template pulls too much. A description template of
%excerpt%uses the whole manual excerpt, and some excerpts are full paragraphs written for archive pages. - Content pasted into the description field. Copying the first paragraph of a post into the description is quick, but first paragraphs are rarely written to fit 160 characters.
- Plugin-generated descriptions. Some tools build descriptions from the opening of the content without trimming at a sentence boundary.
How to fix it in WordPress
- Cut the preamble. Delete openers like "In this article" or "Welcome to". Start with the answer, the benefit or the key fact.
- Keep one idea plus one supporting detail. A description is a pitch, not a summary. If you need three sentences, you probably need to choose.
- Trim it against the preview, not the counter. In Hydrogen SEO, the Meta description field sits in the post's SEO Settings sheet (the keyboard shortcut opens it), and its SERP preview marks the point where a desktop result cuts off. Wide letters like W and M run out of room sooner than a character count suggests, so trust the preview.
- Fix the template if many pages are affected. Under Hydrogen SEO → Titles & Meta, check what the post type's description template uses. If excerpts are long, consider writing shorter excerpts, or write descriptions directly for the pages that matter.
- Find every long one. The Hydrogen SEO site audit lists descriptions that are too long across the site. With a connected account, you can ask the Hydrogen AI agent to tighten them and review each change.
When you can ignore this warning
A description of 165 characters where the last few words are a harmless tail is not worth fixing ahead of real problems. The warning matters when the cut hides something important: a price, the answer to the query, or the reason to click. Read the first 150 characters on their own. If they stand up, the page is fine.
The pixel-width preview tool shows exactly which words fall past the cut, which makes that judgment quick.
How to check the fix
Open the page source and read the length of the name="description" value, or paste it into the SERP snippet preview to see the truncation point in pixels. Once Google has recrawled the page, search the query you care about and compare the snippet it shows with what you wrote. A rewritten snippet usually means the description drifted away from what the page itself says.
Common questions
How long can a meta description be?
There is no hard limit, but Google usually displays about 150 to 160 characters on desktop. Anything beyond that is typically cut off.
Does Google penalize long meta descriptions?
No. There is no penalty. The only cost is that searchers do not see the truncated part, and long descriptions are more often replaced by Google's own snippet.
Is mobile truncation different?
Yes, mobile results often show fewer characters than desktop. Putting the key information in the first 120 characters covers both.
