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.
Use recipes designed specifically for a sheet configuration. Sheet cakes are usually thinner than standard cakes so they can be prone to texture and moisture issues. Prepare your pans well with flour, butter, and parchment paper to prevent your sheet cake from sticking.
