You can, yes.
If you really want it to be read, though, you'll get it all on one side of one page!
Scroll down and read about resumes.
Also, is it okay to print it double-sided to your potential employer or they won't accept that?
A potential employer will accept any resume. The big question, as Writeacher noted, is whether she will actually read it.
One-page resumes have a much better chance of being read than longer resumes.
You would need to check with the individual potential employer. Some will; others won't. The point is that, usually, what you don't get onto that first side won't get read. They have too many to read, and they will not read them carefully until maybe they're down to the five or six they decide to interview.
And if there are any errors at all, it'll go into the "round file" right then. Make sure it's perfect.
On the second page of my resume, it only takes up at least one-third of the page anyways. That should be fine. Thanks!
