Meta Title and Description: How Long, and What Actually Matters
4 min read3 October 2026By Muhammad Abdullah
Two short pieces of text decide whether someone clicks your page in search results: the title tag and the meta description. They are easy to get roughly right and easy to get quietly wrong, mostly by writing too much, or by writing for search engines instead of the person reading the result.
The title tag: about 60 characters
Google typically shows around 60 characters of a title before cutting it off with an ellipsis. The real limit is measured in pixels, roughly 580 pixels of width, not in characters, so a title full of wide letters like W and M truncates sooner than one full of i and l. Aim for about 60 and preview it to be sure.

- Put the main topic first. People scan the start of a result, and words at the front carry the most weight.
- Make every page's title unique. Duplicate titles across a site leave search engines guessing which page to show.
- Put your brand at the end, if at all. It is the least useful part of the title to someone who does not know you yet.
- Write it for a person. A title stuffed with repeated keywords reads as spam and earns fewer clicks, not more.
The meta description: about 155 characters
The description is the line of text under your title. Google shows roughly 155 to 160 characters on desktop and a little less on mobile. Like the title, it is measured in pixels, so treat the number as a target rather than a hard rule.
<meta name="description" content="Format, minify and validate JSON in your browser. Errors point to the exact problem. Nothing is uploaded.">The description is not a ranking factor
This surprises people. Google has said plainly that the meta description does not directly affect where a page ranks. What it affects is whether people click once they see you, and that matters a great deal. Think of the description as the sales line under your listing: its job is to give the reader a reason to choose you over the result above and below.
A good description says what the page does and why it is worth the click, in plain words. It answers the question the person typed.
Google often rewrites it anyway
Google frequently replaces your description with a passage pulled from the page, especially when the query is specific or your description does not match it well. You cannot fully prevent this. What you can do is write a description that matches the page's main intent closely, and make sure the page itself contains clear, quotable sentences, so that whichever text Google picks still reads well.
The canonical tag belongs with them
If the same content is reachable at several addresses, with and without a trailing slash, with tracking parameters, over http and https, a canonical tag tells search engines which URL is the real one. Without it, your own pages can split their ranking signals between duplicates.
<link rel="canonical" href="https://example.com/json-formatter">Social sharing is a separate set of tags
The title and description control search results. When a link is shared on social platforms or messaging apps, those platforms read Open Graph tags instead: og:title, og:description and especially og:image. They can differ from your search tags, and the image is usually what earns the click on a social feed. Set both sets deliberately rather than hoping one covers the other.
Common questions
How long should a meta title be?
About 60 characters. Google measures roughly 580 pixels of width, so the exact cutoff depends on the letters used.
How long should a meta description be?
About 155 to 160 characters. It is measured in pixels too, and shows slightly shorter on mobile.
Does the meta description affect SEO rankings?
Not directly. It affects click-through rate, which is why it is still worth writing carefully.
