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.
It is virtually impossible to torte (cut in half) a sheet cake without it cracking or crumbling. Always chill the sheet cake if you are going to torte it so it is firm and cuts smoothly. Nevertheless, it is better to bake the layers in separate pans.
