Baking pan size converter
Enter the pan a recipe calls for and the pan you own. You get what each one holds, in cups, and how much to scale the recipe.
How the volume is calculated.
- Round pan: volume = π × (diameter ÷ 2)² × depth.
- Square, rectangular or loaf pan: volume = length × width × depth.
- Cups = cubic inches ÷ 14.4375. A US gallon is 231 cubic inches and holds 16 cups.
The result is the capacity to the brim with straight sides. It is for comparing pans, not for how much batter to pour in. Pans with sloped sides, which includes most loaf pans, hold a little less; for an exact number, fill the pan with water one cup at a time. This page gives no baking times: a different pan changes how deep the batter sits, so check for doneness the way the recipe describes.
