The short answer
One page is enough for many early-career candidates and focused role changes. Two pages is normal for experienced professionals with relevant depth. Length matters less than density: every line should earn its place.
When one page fits
Students, recent graduates, and applicants with under ~7 years of directly relevant work often fit one page if bullets are tight. Cut old part-time jobs, unrelated coursework, and duplicate skills.
When two pages are fine
Technical, managerial, and academic tracks often need two pages to show scope across roles. Keep page two for continued experience and supporting sections — not a second copy of your hobbies.
- Trim roles older than ~10–15 years to title, company, and one line unless highly relevant
- Merge similar bullets across years when stories repeat
- Move long lists of tools to a skills section instead of repeating in every role
CV vs. resume
In Europe, "CV" may mean a longer document with more history; in US hiring, "resume" usually means a concise summary. Follow local norms and the employer's instructions when they specify length.
