According to 6 Figure Resumes, as a general rule of thumb, two pages are typical for executives with around 10 years of experience. Each additional five years might add another page. Resumes rarely exceed four pages, because experience more than 20 years ago usually doesn’t merit much space. A senior executive resume could be a single page if conditions permit, this is sometimes seen with finance resumes.
Entry level resumes and those with minimal experience should not exceed one page.
