Do not automatically copy a friend's resume just because it worked for him or her. Use others' resumes as a source of ideas for your own. For most undergraduates, one page is the common length since many lack experience. People with added experience and or degrees may need a two-page resume. Do not go on to the second page for just one or two lines.
Employers scan most resumes within a few seconds and prefer one page.
Length may also vary by field. A professionally typeset resume is impressive if you can afford the cost. However, a resume prepared carefully with a good laser printer can be just as effective. Light colored resume paper is generally preferred. Be sure not to use speckled paper when faxing a resume.
