TopicWhat size is a 1/2 sheet cake pan.

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.
In general, the 13-by-9-inch cake will take about 5 to 10 minutes less than the 9-inch layers. To be safe, start checking about 15 minutes before the time in the original recipe. Cupcakes usually take about half as long as a 9-inch round cake. If the cake called for 30 to 35 minutes of baking time, start checking the cupcakes after 15 minutes.
