Resume length: the case for one page (and when two makes sense)

The recruitment internet has spent two decades arguing about whether a resume should be one page or two. The argument is usually framed as a rule: "under 10 years, one page; over 10, two." That's a heuristic, not a rule, and it gets the wrong answer at least a third of the time.

The honest version is: most resumes should be one page, most of the time, regardless of experience — and the reason has more to do with how recruiters read than how much you've done.

How recruiters actually read a resume

Eye-tracking studies (Ladders, 2018, replicated in 2020) put initial-screening time at roughly 7 seconds per CV. In those seven seconds the recruiter is scanning for:

• Your current role and company (top of page 1)
• Your previous role and how it relates
• A glance at education / location
• Whether your title path matches the job they're filling

That entire scan happens on page 1. If you've buried the relevant content on page 2, it's effectively invisible during the first pass — and the first pass is the one where most candidates are filtered out.

This is the real argument for one page: not that two is wrong, but that the second page is rarely read in the screening phase. Putting your strongest material below the fold costs you the interview.

When two pages is genuinely correct

There are situations where two pages is the right call, and they're more specific than years-of-experience:

1. Senior roles where titles + scope are the qualification. A CTO with 20 years of leadership across five companies needs space to show breadth. Cramming it onto one page makes you look junior.
2. Academic, research, or government roles where publications, grants, or detailed project lists are part of the assessment. Same reasoning: the second page is expected to exist.
3. Career-change with relevant transferable content that doesn't compress without losing the connective tissue. Sometimes the explanation of why a five-year stint as a teacher is relevant to a product manager role takes more room than you can spare.

Notice what's not on this list: "I have 12 years of experience." Years alone don't justify a second page. Density of relevant material does.

What "one page" actually means

A one-page resume isn't a layout constraint, it's a prioritisation constraint. The discipline of one page forces three decisions:

• Which roles to include in detail vs. summarise. Your first job after college, listed with four bullets, almost never serves you in your tenth year. Roll older roles up into a single "Earlier experience" line.
• Which bullets to cut. Most candidates have 6–8 bullets per recent role. The right number is 3–5. Cutting forces you to keep the achievements, not the responsibilities.
• Which sections to skip. "References available on request" is the most-cited zombie line in CV history. Cut it. Cut the objective. Cut the photo unless you're in a country/industry where it's standard.

If you can't say it in one page, you usually haven't decided what you want to say yet.

The middle case: 1.5 pages

Resumes that run 1.2–1.5 pages are the worst of both worlds. They violate the one-page expectation without committing to two, and the orphaned content on the second page (one paragraph, three bullets, a logo) reads as a rough draft.

Practical rule: if you're at 1.2 pages, cut to one. If you're at 1.6 pages with substantive content on page 2, expand to two and balance the visual weight.

Length and ATS parsing

A common worry: does a longer resume hurt your ATS score? The short answer: not directly. Modern parsers handle multi-page PDFs cleanly, and scoring is keyword-and-context-based, not length-based.

But there's an indirect cost: the recruiter's eye-tracking pattern. Even after the ATS surfaces your CV for human review, the recruiter still spends ~7 seconds on page 1. A one-page resume forces your best content into that window. A two-page resume gives you the same 7 seconds but with twice the surface area to choose from.

The seven-second test

Open your resume. Set a phone timer for 7 seconds. Look at page 1.

In those 7 seconds, did you see:

• Your name and current title at the top
• The company / role you're applying from (most relevant context)
• One specific achievement with a number in it
• Your years of relevant experience, implicitly or explicitly

If yes, page 1 is doing its job. If you had to scroll, or the achievement was buried in paragraph form, you have a structural problem that more pages won't fix.

The honest answer

For ~80% of professionals — anyone under 15 years of experience in a non-academic, non-government role — one page is the right answer. Not because there's a rule, but because page 1 is where the decision gets made and consolidating onto it forces you to prioritise.

For the other 20% — senior leadership, academia, research, public sector — two pages is correct and expected. But every line on page 2 should earn its place.

Either way, the question isn't really "one page or two". It's: if a recruiter only reads page 1, did I show them why I should be interviewed? If the answer is yes, you've solved the length problem.
