Paper in my place includes everything from small sticky-back notes to 12” x 12” scrapbook paper. I once owned a scrapbook supplies store and sold through direct sales, so I probably have more than I will ever use.

It is organized from cardstock to regular paper, and from solids to prints, all of it in WBlBr ROYGBIV order. This makes it easier to locate when I am looking for a specific color or colors for a project.
I also have 12” x 12” paper stored in a container like this one:
