How long should a title tag be?

Roughly 580 pixels on desktop, which averages around 55-60 characters. Pixel width matters more than character count because capital letters and wide characters take more space.

How long should a meta description be?

Roughly 920 pixels on desktop, averaging about 150-158 characters. Front-load the important information since the end is what gets truncated.

Does Google always use my title tag?

No. Google rewrites titles in a meaningful share of results when it judges its own version more useful, often pulling from the H1 or page content. A clear, accurate title is more likely to be kept.

Is the meta description a ranking factor?

No. It does not affect rankings directly, but it affects click-through rate, which is why it is worth writing well.

Title and Meta Description Length: Measure Pixels, Not Characters

RankWise · On-page SEO

Almost every SEO guide gives title and meta description limits in characters. That advice is wrong, and it's why titles that "should" fit still get cut off in search results.

Google truncates by pixel width, not character count

Search results render in a fixed-width container. What determines whether your title fits is how many pixels it occupies — and characters are not equal widths.

Title (both 55 characters)	Approx. width	Fits?
illicit tiny titles fit in little lists till it fills	~440px	Comfortably
MAXIMUM WARM WOMBAT MARKETING & MEDIA MANAGEMENT CO.	~700px	Truncated

Same character count, wildly different outcomes. Capitals, M, W, &, and em dashes are wide. Lowercase i, l, t, and punctuation are narrow.

The practical limits

	Desktop	Mobile
Title	~580px	~920px (wraps to two lines)
Meta description	~920px	~1300px

Google doesn't publish these numbers and they shift over time, so treat them as close approximations rather than hard rules. The character equivalents people quote — 60 for titles, 155 for descriptions — are averages derived from these pixel widths, which is why they work most of the time and fail on capital-heavy titles.

Google rewrites your title anyway — so why bother?

A fair question. Google replaces titles in a meaningful share of results when it judges its own version more useful, typically pulling from your H1 or on-page text.

Two reasons it still matters. First, your title is the strongest signal Google has about what the page is; a good one is more likely to be kept. Second, when it is kept, truncation costs you the end of the sentence — usually where your brand name sits.

Meta descriptions get rewritten even more often, but the same logic holds: supply a good one and you're often shown it.

What actually makes a good title

Primary topic first. If it truncates, you lose the end, not the beginning.
One clear subject. Stuffing three keywords in dilutes all three.
Brand at the end, separated by a pipe or dash — and accept it may be cut on long titles.
Unique across every page. Duplicate titles make pages compete with each other.
Written for a human deciding whether to click, not for a crawler counting terms.

And a good meta description

It isn't a ranking factor. It's an advertisement for the click. Treat it as copywriting.
Front-load the important part — same truncation logic applies.
Describe what's actually on the page. Mismatched descriptions get rewritten or ignored.
Include the search term naturally — Google bolds matching words, which draws the eye.
Leaving it blank is a choice, not a mistake, if you'd rather Google pull relevant text per query. But writing one gives you control.

Check yours

The SERP snippet preview tool on this site measures actual pixel width using canvas text metrics rather than estimating from character count, shows desktop and mobile side by side, marks exactly where truncation falls, and outputs the HTML to copy. It runs entirely in your browser — nothing is sent anywhere.
