Hi everyone! I was just wondering how many servings are in a 4 inch round and a 5 inch round? I generally follow Wilton's serving chart and they don't have those two. My cake pans are 2 inches high and each tier I make is about 5 inches with filling. Thank you in advance!

ASurface area for a round cake is π * radius * radius, so for a 4" you have ~12.5 sq in, and a 5" is ~19.6 sq in. Divide by a 1"x2" cross-section for a wedding-size serving and you have 6.25 and 9.8 servings, respectively. For a 1.5"x2" party-size serving you have 4.2 and 6.5 servings.
