Can a resume be two pages or will recruiters immediately dismiss it?

I just graduated college and am entering my master’s program. It is only one year so I am updating my resume to start applying to full time jobs. I had a ton of relevant extracurriculars and honors in undergrad. I had an internship last summer and am a TA this summer. With all my skills, extracurriculars, and experience, I really don’t know how to keep it to one page. Does anyone have any experience with what to do with this?
