The short answer
- Under 5 years of experience: one page. If it doesn't fit, the problem is almost never that you need more space — it's that you're keeping lines that aren't earning their place.
- 5–15 years: one or two pages, and two is fine once you genuinely have two pages of relevant, distinct achievements to show — not two pages of restated duties.
- 15+ years, or an academic/research role with a publication list: two pages is standard, and a longer CV is expected in academia specifically.
Length is a symptom, not the actual problem
Nobody rejects a résumé for being one line over a page. What actually gets a résumé set aside is the same thing whether it's one page or three: the reader can't find the two or three things that matter in the time they're willing to give it. A short résumé can still bury the point under a wall of generic duties. A long one can still be tight if every line is doing real work.
So "how long should it be" is really "how much have I actually proven, stated as concisely as I can state it" — and for most people early-to-mid career, the honest answer to that fits comfortably on one page once the padding is gone.
What padding actually looks like
If you're at two pages and not sure you've earned it, these are the usual culprits — not because they're always wrong, but because they're the first place extra length hides:
- A job from 12+ years ago with the same bullet detail as your current role. Early-career jobs can usually collapse to a title, company, and dates once you have more recent, more relevant experience to lead with.
- Bullets that restate the job title instead of a result. "Responsible for managing the team" is a duty. "Managed a team of 6, cut onboarding time from 3 weeks to 8 days" is evidence. The second one is worth the line; the first usually isn't.
- A skills section that lists everything you've ever touched. A skill you used once, three roles ago, and won't put on a job description isn't pulling weight — it's noise between the reader and the skills that actually match.
- An objective statement. The job title in your header and the sentence structure of your work experience already say what you're aiming at. A paragraph explaining it again is space a bullet could have used.
The one-page trap: cutting evidence to hit a number
The other failure mode is real too — someone with a genuinely full career forcing it onto one page by shrinking the font to 9pt and killing the margins. That's worse than two honest pages. A parser and a recruiter both need whitespace and standard section breaks to actually read the thing; a page that's been compressed to fit an arbitrary rule usually reads worse than it would at its natural length.
If you're cutting real, distinct, relevant achievements to hit one page — stop cutting achievements and start cutting the least relevant job first, or move it to a single line instead of deleting it outright.
