SERP Snippet Length Rules for Titles and Descriptions

You wrote a precise, persuasive title, and Google shows the first two thirds of it with an ellipsis where the payoff used to be. The length rules behind that cut aren't secret, but they're measured in pixels rather than characters, which is why advice like keep it under 60 needs an asterisk. This article lays out the working limits for SERP snippet length, walks through a truncation fix, and covers the case no limit can save you from: Google rewriting your title entirely.

Two lines of text carry the whole click decision

Ranking gets you on the page. The snippet gets the tap.

A search result is essentially a title, a URL and a description, and searchers decide in about a second based on those alone. Truncation isn't cosmetic damage: when the cut lands mid-phrase, the snippet reads as unfinished, and unfinished loses to the intact result one position down.

The scenario that sends people to a preview is common. An agency ships thirty product pages, every title follows the pattern Product Name | Category | Brand Name, and on the live results page every one of them is cut before the brand appears. Thirty titles, one template bug, discoverable in advance by pasting one of them into a preview.

The length limits that hold in practice

About 600 pixels for titles, 920 for descriptions.

Google cuts desktop titles at roughly 600 pixels of rendered text, which usually lands between 50 and 60 characters. Descriptions get about 920 pixels on desktop, near 150 to 160 characters, and about 680 pixels on mobile, closer to 120. Google doesn't publish these numbers and adjusts its layout from time to time, so treat them as working limits based on common measurements.

The Google SERP Preview Tool uses those limits. It measures the title in 20 pixel Arial and the description in 14 pixel Arial, using your browser's own text measuring, and cuts each one at the last whole word that fits before adding an ellipsis. Each field shows its character count and approximate pixel width, and turns red with a warning once it passes the limit.

Pixel width vs character count in the title cutoff

Why two 58-character titles can end differently.

Google measures rendered width, so letters don't cost the same. At 20 pixels, WWWWW is about 94 pixels wide and lllll about 22. A 58 character title full of capitals, W's and M's can be cut early, while a 64 character title of narrow lowercase letters sometimes fits.

Character counts are still a useful first guide, because nobody can eyeball pixels while writing. The practical adjustment is a margin: treat about 55 characters as a safe ceiling when your title runs heavy on capitals or wide letters, and let the pixel counter decide the close calls.

A worked truncation example, before and after

One title, two edits, no ellipsis.

Input title, 77 characters: Complete Guide to Growing Heirloom Tomatoes in Raised Garden Beds | GreenSpot. It measures about 750 pixels, well past the limit, and the preview renders it as Complete Guide to Growing Heirloom Tomatoes in Raised followed by an ellipsis. The topic survived, but the phrase stops mid-thought and the brand is gone.

Edit one drops filler: Growing Heirloom Tomatoes in Raised Beds | GreenSpot, 52 characters and about 505 pixels, fully intact. Edit two front-loads harder for a competitive query: Heirloom Tomatoes in Raised Beds: Planting to Harvest, 53 characters and about 492 pixels. Both fit, and choosing between them is a copywriting call the length rules no longer constrain. The description gets the same pass, aiming for 120 to 155 characters that read as one complete thought.

Type a search keyword such as heirloom tomatoes and the preview bolds the matching words, as Google does. It is a quick way to see whether the words people search for actually appear in the snippet.

When Google rewrites titles instead of cutting them

Sometimes the scissors aren't the problem.

Since 2021, Google has replaced a noticeable share of title tags in results, pulling substitutes from H1s, anchor text or page content when it judges the written title a poor match. The titles it keeps tend to be accurate rather than clever, lead with the topic, avoid piles of repeated phrases, and don't follow one boilerplate pattern across fifty near-identical pages.

A preview can't simulate the rewrite, and no tool can, because it depends on the query. What a title that fits and describes the page buys you is fewer reasons for Google to step in. The titles replaced most often were overlong, stuffed or interchangeable to begin with.

Snippet habits that invite the ellipsis

Recurring self-inflicted truncations.

Watch for these while drafting.

Brand-first templates like Brand Name | Category | Page Topic, which spend the visible width before saying anything the searcher asked for
Ignoring the date Google adds in front of some descriptions, which uses part of the space
Writing only for desktop, when the mobile view cuts the description at about 680 pixels and hides the breadcrumb path
Padding titles to reach 60 characters because longer feels more thorough; short and intact beats long and clipped

Where the Google SERP Preview Tool fits among the meta tools

Draft here, generate and audit next door.

The Google SERP Preview Tool is the drafting bench. Paste a live URL and click Preview existing URL to load its title, description, canonical, site name and favicon, or type fresh copy, then switch between the Desktop and Mobile tabs until nothing is cut. The site name and favicon appear above the URL as they do in current results. When the copy is final, the Meta Tag Generator wraps it into a complete head block with the canonical, Open Graph and Twitter Card tags. After deploy, the Meta Tag Analyzer checks the live page and warns when a title or description is wider than Google shows. Preview before, generate during, audit after.
