For a shortcut, remember that a 9-inch round cake pan holds about 6 cups (if the batter is 1 1/2 inches deep). A 13-by-9-inch pan holds 12 cups. And a standard cupcake pan, with 1/2 cup batter in each of six cups, holds 3 cups. So a two-layer cake batter should convert easily to 12 cupcakes or a sheet cake.
Because size conversions can get confusing, one way you can simplify things is to choose pans that have lengths or widths that are divisible by each other. For example, if your “full” sheet pan is 18” x 24”, you should find a half size pan that’s 12” x 18” and a quarter pan that’s 9” x 12”, since those numbers divide evenly into each other.
