The short answer
In the US and Canada, a resume is a one-to-two page summary aimed at one job; a CV is the long academic record used for research and faculty posts. Almost everywhere else — the UK, Europe, Australia, much of Asia — CV is simply the everyday word for a resume.
So the country of the posting tells you more than the word does.
Where the two genuinely differ
A North American curriculum vitae runs as long as the career requires. Publications, conference talks, grants, teaching, committee service, references in full. Four pages is unremarkable, and nobody trims it to fit.
A resume is the opposite discipline: one page, aimed at the role in front of you, rewritten for the next one.
| Resume, and most CVs outside North America | Academic CV | |
|---|---|---|
| Length | One page, two if the career warrants it | As long as the record is |
| What leads | Whatever is most relevant to this job | Reverse chronological throughout |
| Publications | Rarely present | The center of the document |
| References | Usually omitted | Often listed in full |
| Tailoring | Rewritten per application | Largely stable between applications |
Name, contact details, education and experience sit in both, written much the same way.
If you can't tell which is meant
Look at who is asking. A university department, a lab, a fellowship, a grant committee — that's the academic sense. A company, an agency, a recruiter, anywhere outside North America — that's the one-to-two page document, whichever word they used.
When a non-academic US employer writes "send your CV", they almost always mean a resume. Sending one costs you nothing either way.
Building either one here
Same editor, different sections. youcanfind.me/resume opens with experience, education and skills already in place. "Add section" gives you publications, certificates, awards, languages, volunteering and references — the sections that turn a resume into an academic CV.
Two things worth knowing:
Section names are yours to change. Click a section title and type over it: "Publications" becomes "Selected Publications", "Experience" becomes "Employment History". The heading is text, not a fixed label.
Order is yours too. Each section has up and down arrows. An academic CV usually wants education and publications above work history; a resume usually wants the opposite.
Length and printing
A CV that runs to several pages prints correctly — the print layout paginates to A4 and keeps entries whole where the page allows. One-click PDF download applies to English content in the Resume Clean layout; everything longer or in another language goes through the browser's print dialog, which produces the same kind of file.
Which word to put on the file
Theirs. If the posting says CV, name the file CV. If it says resume, name it resume. This is the single cheapest thing on the list and the one people most often get backwards.
