Meta Description Length: The Right Character Count
The right meta description length is about 150 to 160 characters. Here is why that number works, what gets cut off, and how to check every page fast.
The right meta description length is 150 to 160 characters, or roughly 920 pixels wide on desktop. Google truncates anything longer with an ellipsis, so front-load the point in the first 120 characters. If a description runs shorter than about 70 characters, Google often rewrites it with page text instead. Aim for one or two tight sentences that a person would actually click.
What is the ideal meta description length?
Google measures descriptions by pixel width, not character count, but characters are the easier proxy. Here is the range that holds up in practice:
- Desktop: up to ~158 characters before truncation
- Mobile: ~120 characters, since the column is narrower
- Safe target: 150 to 160 characters, with the key message in the first 120
- Too short: under 70 characters usually triggers a Google rewrite
Write for the mobile cut first. Most searches happen on phones, and a description that reads complete at 120 characters will never look chopped.
Why does meta description length matter?
The meta description is not a ranking factor. It is a sales line. Its only job is to earn the click once you already rank. A description cut off mid-sentence looks careless and buries your call to action. A description that is too vague gets replaced by a random sentence Google scrapes from your page, which is rarely the sentence you would choose.
There is a newer reason to care too. AI answer engines read these tags to summarize what a page offers. A sharp, self-contained description makes it more likely that ChatGPT or Perplexity describes your page the way you want, instead of paraphrasing a competitor who wrote a clearer one.

Good and bad examples
Too long (gets cut)
"We offer a comprehensive suite of accounting tools designed for freelancers, small businesses, agencies, and enterprise teams who want to manage invoices, track expenses, handle payroll, and file taxes all in one..." The reader never reaches the point.
Too short (gets rewritten)
"Accounting software for freelancers." Accurate, but 36 characters gives Google no reason not to swap it out.
Right length, clear payoff
"Send invoices, track expenses, and file taxes in one place. Built for freelancers who hate accounting. Free to start, no card needed." That is 132 characters, complete on mobile, and it says exactly who it is for.
How do you write one that fits?
- Lead with the outcome or the benefit, not your brand name.
- Name the audience so the right person self-selects.
- Keep it to 150 to 160 characters and check the mobile cut at 120.
- Include one natural phrase that matches search intent, not a keyword stuffed in.
- End with a light nudge: what happens when they click.
- Make every page unique. Duplicate descriptions confuse both Google and AI engines.
Check every page, not just the homepage
Most sites get the homepage right and forget the other 40 pages. Blog posts, product pages, and category pages all ship with auto-generated or missing descriptions. Auditing them by hand does not scale.
Scan the whole site at once with Page Audit, then use the free SEO audit walkthrough to fix what it finds. Once your descriptions are tight, check how AI engines describe you with how to check AI visibility. Length is a small detail. Getting it right across every page is what compounds.
