Common App Resume

Is there a limit for how long a resume submitted can be?

I seem to remember each section (awards, activities) only has a certain amount of fields for you to fill in. It’s not a matter of attaching a 4 page file.

One of the schools I am applying to allows you to submit a resume if you choose in addition to filling out the activities section. I know that other colleges also take a resume in addition so I was just wondering if they normally have a limit (mainly because the 150 characters allowed in the activities section is not a lot).
