I go for two pages (two sides of a single page) myself. But I think US resumes are a slightly different concept that goes into exhaustive detail about work history. As somebody that has acted as hiring manager in the past, I definitely preferred the shorter curriculum vitae format - it shows attention to detail and an understanding of what is relevant to the job at hand. I have had feedback on my own CV from time to time that it didn't go into enough detail, so it's horses for courses I suppose ...
You've got it backwards. Resumes are typically one page. CVs are detailed. In the USA most places will ask for a one page resume. I've noticed some tech companies want a longer resume or a CV though.
Oh my CV is 3 pages in length, but you know what I can do and most of where I have worked on the first page. The last 2 pages are detailed breakdowns of where and what I have done.
