How search engines truncate titles and descriptions (pixels, not characters)
Most SEO advice says "keep your title under 60 characters." That number is a useful proxy, but search engines don't actually count characters. They measure pixels. Two titles of the same character count can render at completely different widths, and only one of them gets truncated.
Why pixels matter more than characters
Search results use a proportional font. Each letter has its own width:
- "W" is about 16 pixels wide
- "M" is about 15 pixels wide
- "o" is about 9 pixels wide
- "i" is about 4 pixels wide
- "l" is about 4 pixels wide
So the title "Will it work? Will it work? Will it work? Will it work?" (58 characters) is much wider than "How to fix it quickly without losing your data forever yes" (also 58 characters). Search engines might truncate the first one and keep the second one intact.
The actual pixel limits in 2026
| Element | Desktop | Mobile |
|---|---|---|
| Page title | ~580 px | ~540 px |
| Meta description | ~920 px | ~980 px |
(Yes, mobile description width is wider than desktop. Mobile search-result layout uses a different font size that lets more text fit in the same visible row count.)
These limits aren't published officially. They come from measuring live SERPs and are stable enough that every professional SEO tool uses them. They may shift if search engines change their SERP layout.
The fonts search engines use
For desktop, titles render in approximately Arial 20px bold. Descriptions render in approximately Arial 14px. Mobile uses slightly different sizes. Most measurement tools (including ours) use these settings in HTML Canvas to compute the pixel width of any text accurately.
If you ever want to verify a measurement yourself, open browser DevTools, find the title element in a live search result, and inspect its computed font and width. The pixel number you get is what every tool is approximating.
The 60-character rule still works as a rough guide
Most titles between 50 and 60 characters land safely under 580 px. The rule fails when you load up on wide letters (W, M, capital letters in general). When in doubt, measure.
What happens when you go over
Search engines cut off the title at the nearest word boundary before the pixel limit and append an ellipsis (…). If your call-to-action or main keyword was in the cut-off portion, you lose it.
Example:
WRITTEN TITLE (660 px): "How to fix the Windows 11 update error 0x80070643 in 5 minutes" WHAT THE SEARCH RESULT SHOWS (580 px): "How to fix the Windows 11 update error…"
The "5 minutes" hook, the part that earned the click, is gone. The user sees only the problem, not the solution.
The same applies to meta descriptions
Descriptions truncate at ~920 px on desktop. That's roughly 155–160 characters in plain text. The difference here is that search engines often rewrite your description entirely if they think a better snippet from the page body fits the query. In that case, your description still controls Open Graph and Twitter Card previews, so don't skip it just because search engines might rewrite.
How to write tags that always fit
- Front-load the keyword and benefit. Put what matters in the first 30 characters so it survives any truncation.
- Avoid all-caps words. "BEST" is wider than "best", and looks like shouting.
- Cut filler. "Discover how to" → "How to". "The ultimate guide to" → "Guide to". Every removed word makes the line tighter.
- Move your brand to a separator at the end and accept that search engines may truncate it. "Real headline | YourBrand" → if cut, the user still gets the real headline.
- Pixel-check before publishing. A character counter lies. A pixel counter tells the truth.

What search engines decide on their own
Important caveat: even a perfectly-sized title may be rewritten by search engines. In recent years, search engines have been more active about generating their own titles based on page content, H1s, and anchor text. The pixel limit is simply where they truncate if they use yours at all. It does not mean a search engine will always use your title.
The practical conclusion: write good titles within pixel limits because (a) search engines often do use them, and (b) the same titles drive social shares, browser tabs, and email previews where search engines have no say.
