Your resume should never be more than one page. There is no exception to this rule. When it comes into the hands of the hiring manager, you’ll have a short amount of time to hold their interest long enough to see how awesome you are.
If you have lots of experience, personal projects or education and accolades, effectively use the page. This means columns. Keep all the data short and sweet and organize them in a non-uniform grid. You can find examples of this online, but the goal is to highlight certain aspects of your resume while letting them find any important information quickly.
