How to Convert Between Baking Pan Sizes
Formula
Scale Factor = New Pan Area / Original Pan Area
For rectangular pans: Area = Length x Width
Multiply each ingredient by the scale factor to adapt the recipe.
Example
Switching from a 13x9 pan (117 sq in) to an 8x8 pan (64 sq in) requires scaling to 64/117 = 0.55x the recipe.
Example Calculation
Scale a recipe from a 13x9 inch pan to an 8x8 inch pan.
- 01Original pan area: 13 x 9 = 117 sq in.
- 02New pan area: 8 x 8 = 64 sq in.
- 03Scale factor: 64 / 117 = 0.55.
