One Page, Two Pages, or As Long As It Takes
The one-page rule is a US convention presented as a universal law. What length actually depends on, and what gets cut when it must be shorter.
The one-page rule is stated with more confidence than any other piece of CV advice, and it is a United States convention presented as a universal law. For further reading on planning and time management, see this explanation.
Length depends on the market, the field, the level and what you have done. For an independent public reference, consult Europass CV guidance.
What it actually depends on
Market. One page is the strong US convention. Two pages is standard and expected in the UK. Australia accepts two to three. Continental Europe varies. See what differs by market.
Field. Academic and research CVs are as long as the record requires and there is no upper limit. Some technical, medical and legal contexts expect detail. Most commercial roles do not.
Level. A graduate with one page has one page of material. Someone with twenty years compressing it to one page is deleting things a reader needs.
And the format the employer asked for. Where a length is stated, that is the answer.
The real rule
As short as it can be while containing what a reader needs to decide.
Which for most people, in most commercial roles, in most markets, is two pages.
A dense one-page CV is worse than a spacious two-page one. Removing white space to hit a page count produces a document that is skimmed and abandoned, which defeats the purpose of the constraint.
When one page is right
Early career, with under about five years of experience.
United States applications for most commercial roles.
Where the employer says so.
And where you genuinely have one page of relevant material. Padding to reach two is more visible than stopping at one.
When more than two is right
Academic and research, where the CV is a record rather than a pitch.
Some senior and executive roles, where the scope requires it — though even here, a focused two or three pages usually beats six.
Technical roles in some markets, where a project list is expected.
Public sector applications in some countries, which have their own prescribed formats.
Never more than two pages because you could not decide what to cut. That is the version readers notice.
What to cut, in order
When it must be shorter, cut in this sequence.
Roles more than about fifteen years old, reduced to a line or grouped: "Earlier roles: customer service and operations positions at regional retailers, 2004–2011."
Duties that were obvious from the title. A reader knows what an accountant does.
Detail on older roles. Recent work gets the bullets; older work gets a line.
Skills lists that repeat what the experience already shows.
Hobbies, unless the market expects them or they are genuinely relevant.
The personal statement, if it is not saying anything. See the summary at the top.
Weak bullets. Three strong ones beat six mixed, and the mixed set dilutes the strong ones.
And anything not relevant to this application. Length is a tailoring problem before it is a formatting one. See tailoring a CV.
What not to cut
White space. The first instinct and the wrong one.
Font size below about 10pt. A CV nobody can read comfortably is not shorter, it is worse.
Margins to nothing.
Dates, or anything that makes the chronology unclear.
The achievements, in favour of keeping the duties. It is the wrong way round — duties are inferable and achievements are not. See quantifying achievements.
The page break
Small point, frequently missed.
Do not break a role across pages where you can avoid it.
Put your name on the second page. Pages get separated, printed and shuffled.
Make the first page work alone. Many readers do not reach the second one, so the strongest material belongs above the break — which is a stronger constraint than the total length.
The short version
One page is a US convention, not a universal rule. Two pages is standard in the UK and much of the world.
As short as it can be while containing what a reader needs. For most commercial roles, two pages.
A dense one-pager is worse than a spacious two-pager — white space is the last thing to cut, not the first.
Cut old roles, obvious duties and weak bullets, in that order.
And make the first page work alone, because many readers never reach the second.
