How long should a resume be?
One page. That is the answer for most people, and if you stop reading here, you will be fine.
But "most people" does a lot of heavy lifting in that sentence. If you have 15 years of experience, the one-page rule starts to break. If you are a new graduate, one page should be easy to fill but often is not. And if you are in academia or a federal job, the rules are completely different.
So here is the more honest answer: your resume should be exactly long enough to show your strongest, most relevant qualifications for the specific role you are applying to. Not a line longer.
The real guidelines
Under 10 years of experience: one page. You do not have enough relevant history to justify two, and a recruiter spending 6 seconds on a first pass will not flip to page two anyway. Everything that matters needs to be above the fold.
10-20 years of experience: one to two pages. If your second page has substantive, relevant content (not padding from early-career roles that do not apply anymore), two pages is fine. If the second page is half-empty, cut it. Not sure which roles to keep? Our guide on how far back your resume should go can help you decide.
Executive or senior leadership: two pages is standard. At this level, you have board experience, P&L ownership, and transformation stories that need space. But even here, three pages is almost never justified.
Academic CVs and federal resumes: these are not resumes. They have their own rules. Academic CVs can run 5-10+ pages. Federal resumes require specific detail that corporate resumes do not. If that is your situation, the advice on this page does not apply.
Length is not really the problem
When people ask "how long should my resume be," they are usually asking a different question: "is my resume working?" Length is a symptom, not a diagnosis. A one-page resume full of generic bullets is worse than a focused two-pager with real impact metrics. And a two-page resume padded with irrelevant early-career roles is worse than a tight one-pager.
The better question is: does every line on my resume earn its space? If you removed a bullet point, would a recruiter lose something important? If not, cut it. Our guide on how many bullet points to use per job can help you trim the fat. Do that across the whole document and the length question answers itself.
