A practical guide to how long a resume should be: when one page is enough, when two pages are justified, what to cut, and how DACH conventions change the answer.
Most resumes are too long, not too short. A recruiter spends a few seconds on the first scan, and every line that does not earn its place pushes the line that would have landed you the interview further down. So the honest answer to "how long should a resume be" is short: as long as it takes to make a strong case, and not one line more.
That usually means one page early in a career and two pages once you have the track record to fill them. The page count matters less than the density. A tight two-page resume beats a padded one-pager, and a padded two-pager beats nothing. Here is how to decide which you should have.
If you have under about ten years of experience, aim for one page. Not because of a rule, but because you probably do not yet have two pages of evidence that all pulls its weight. A single page forces you to choose your strongest material, which is exactly the edit a skimming reader needs you to have already made.
One page is the right call when you are a student or recent graduate, when you are early or mid career, or when you are changing fields and most of your old roles no longer argue for the new one. In all three cases, a second page tends to fill up with duties nobody reads.
The risk of one page is not that it looks junior. It is that people shrink the font and the margins to cram two pages of content onto one, and the result is a dense block no one wants to read. If you cannot fit it on one page at a readable size, that is a signal to cut, not to shrink.
Two pages are fine, and often better, once you genuinely have two pages of relevant evidence. The usual triggers are real: roughly ten or more years of experience, a senior or leadership role, a technical field where the specific tools and projects matter, or an academic and research path where publications and grants are part of the case.
The test is not your seniority on paper. It is whether the second page is as strong as the first. If page two is your best older project, a relevant certification, and results that still argue for the job you want, keep it. If page two is a list of every role you held in the 2000s and a "hobbies" section, the resume is a strong one page wearing a weak second page.
One more honest note: a second page only counts if it is a full page. Half a page of content spilling onto a near-empty page two reads as careless. Either cut it back to one page or build the second page out to earn the space.
When you need to get shorter, cut in this order, and most resumes have plenty to give:
The thing you almost never cut is a concrete, provable result. When you are choosing between two lines, keep the one with evidence and drop the one with a job description.
Length is the wrong thing to optimize. Density is the right one: how much real evidence sits in the space you use. A page that is full of specific, provable work is doing its job whether it is one page or two. A page padded out to look substantial is working against you, because the reader has to wade through filler to find the signal.
Two habits keep density high. First, lead every bullet with what came of the work, not the task: "built the weekly reporting the sales team used to plan their pipeline" carries more than "responsible for reporting." Second, never invent a number to fill a line. An honest "removed the manual review step from the release process" beats a made-up "improved efficiency by 40%" that falls apart the moment an interviewer asks how you measured it. Padding is not just wasted space, it is a trust risk.
If you are applying in Germany, Austria, or Switzerland, the rules shift. The German Lebenslauf is conventionally tabellarisch, a clean reverse-chronological table of stations rather than a punchy one-page pitch. Two pages are normal and broadly expected for anyone past their first job, and the document is held to a stricter standard of completeness.
Two specifics matter. First, the timeline is expected to be gap-free (lückenlos): every period accounted for, with months and years, and gaps addressed rather than hidden. Second, the format leans factual and structured over the self-marketing tone common in US resumes. None of this means longer is better. A focused two-page Lebenslauf still beats a four-page life story, and the same cuts above still apply. It just means one page is rarely the goal in the DACH market the way it is elsewhere.
Deciding what stays and what goes is the hard part, and it changes for every posting. JobScalr is a mobile app that reads a specific job ad against your CV, gives you an honest 0–100 match score with the reasoning behind it, and rewrites your resume and cover letter to fit, without inventing skills or experience you do not have. It will not auto-apply for you, and the final read stays yours. It just helps you see which of your lines actually answer the posting, so the version you send is as long as it needs to be and no longer.
