Foam board can be cut into any size or shape. But there are some common foam board sizes that are popular. The 24" x 36" foam board is a nice size for a print almost anywhere. A 36" x 48" looks amazing on a living room wall. A 60" x 72" makes a great menu board. Foam board comes in a glossy white material but if you're looking for a matte black product, gatorboard is perfect!
