Baking Pan Conversion Calculator
Switching pans? This calculator compares the volume of your original pan to your new pan so you can scale ingredients correctly and estimate how bake time should change.
About this calculator
Convert a recipe from one baking pan size to another by comparing pan volumes and adjusting bake time estimates.
Frequently Asked Questions
How does this calculator work?
It calculates the surface area of both pans, then finds the ratio between them. Multiply your ingredient quantities by this scale factor to adjust the recipe.
Why does bake time change with pan size?
A larger pan spreads batter thinner, so it bakes faster; a smaller, deeper pan holds more batter per square inch and takes longer to bake through.
Should I change the oven temperature too?
For much deeper pans, lowering the temperature slightly and baking longer helps prevent a burnt exterior and undercooked center. Always check doneness with a toothpick.
