Areas are measured across the bottom of the pan. A 9-inch round and an 8-inch square hold about the same area, and two 9-inch rounds come close to one 9 × 13-inch pan.

What this converter does not change

  • Baking time: a thinner layer usually bakes faster and a deeper one slower. Start checking early and rely on the doneness signs in the recipe.
  • Depth: the comparison assumes both pans have similar sides. Fill cake pans no more than about two-thirds full.
  • Special shapes: Bundt, tube and springform pans with tall sides are best compared by volume, not by area.
