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 serp snippet 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 real limits, walks a truncation example end to end, and covers the case the rules can't save you from: Google deciding to rewrite 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 serp preview tool is depressingly common. An agency ships thirty product pages, every title follows the pattern Product Name | Category | Brand Name, and on the live results page every single one truncates before the brand appears. Thirty titles, one template bug, discoverable in advance for the cost of pasting one of them into a preview.

The serp snippet length rules that hold in practice

Around 60 characters for titles, around 160 for descriptions.

Google truncates desktop titles at roughly 600 pixels of rendered text, which shakes out near 60 characters for typical mixes of letters. Descriptions get about 920 pixels across two desktop lines, landing near 155 to 160 characters, and mobile squeezes both further while sometimes granting the description a third line.

The SERP Preview applies working limits of 60 and 160: cross either one and the render trims with an ellipsis, with live counters under both fields showing how much room remains. Those aren't promises about every query, they're the thresholds past which truncation stops being a risk and becomes the expected outcome.

Pixel width vs character count in the title cutoff

Why two 58-character titles can end differently.

The pixel width vs character count distinction explains most surprised reactions to live results. Google measures rendered width, so WWWWW occupies about triple the space of lllll in the same font. A 58 character title stuffed with capitals, W's and M's can clip early, while a 64 character title of narrow lowercase letters sometimes escapes intact.

Character counts remain the right working tool because you can't eyeball pixels while writing copy. The practical adjustment is a safety margin: treat 55 characters as the comfortable ceiling when your title runs heavy on capitals or wide glyphs, and let the counter in the preview flag anything past 60 as a probable casualty.

A worked truncation example, before and after

One title, two edits, zero ellipsis.

Input title, 78 characters: Complete Guide to Growing Heirloom Tomatoes in Raised Garden Beds | GreenSpot. The preview trims past its 60 character line, rendering: Complete Guide to Growing Heirloom Tomatoes in Raised Gar followed by an ellipsis. The keyword survived, but the phrase snapped mid-word and the brand vanished.

Edit one drops filler: Growing Heirloom Tomatoes in Raised Beds | GreenSpot, 52 characters, fully intact with room to spare. Edit two front-loads harder for a competitive query: Heirloom Tomatoes in Raised Beds: Planting to Harvest, 53 characters. Both fit; picking between them is a copywriting call the length rules no longer constrain. The description gets the same pass against 160, aiming for the 120 to 155 band that reads as one complete thought.

When Google rewrites titles instead of truncating them

Sometimes the scissors aren't the problem.

Since 2021, Google has replaced a substantial share of title tags in results, pulling substitutes from H1s, anchor text, or page content when it judges the written title a poor match for the query. Knowing when google rewrites titles helps you write ones it keeps: accurate over clever, front-loaded topic, no keyword pile-ups, no boilerplate pattern repeated across fifty near-identical pages.

A preview can't simulate the rewrite, and no tool can, because it depends on the query. What fits-and-describes buys you is fewer reasons for Google to intervene. Titles that get replaced most often are the ones that were overlong, stuffed, or interchangeable to begin with.

Snippet habits that invite the ellipsis

Recurring self-inflicted truncations.

Watch for these while drafting in the preview.

Brand-first templates like Brand Name | Category | Page Topic, which spend the visible budget before saying anything the searcher queried
Counting characters but ignoring the date prefix Google adds to some descriptions, which eats 10 to 12 characters of your 160
Writing only for the desktop render when the mobile tab clamps the description to three lines and shows just the hostname
Padding titles to reach 60 characters because longer feels more thorough; short and intact beats long and clipped

Where the SERP Preview fits among the meta tools

Draft here, generate and audit next door.

The SERP Preview is the drafting bench: paste a live URL with Preview existing URL or type fresh copy, then toggle Desktop and Mobile until nothing clips. When the copy is final, the Meta Tag Generator wraps it into a complete head block with the canonical, Open Graph, and Twitter Card markup attached. After deploy, the Meta Tag Analyzer audits the live page and warns when a title or description drifts outside healthy length bands, which closes the loop: preview before, generate during, audit after.
