Source pan
Target pan

The estimate treats each pan as a simple prism. Round pans use π × radius² × depth; square and rectangular pans use width × length × depth. Use the same unit for every dimension. All three dimensions are required for every shape. Round calculations ignore length; square and rectangular calculations use width and length as entered, without enforcing equal sides.

Enter both pan sizes to compare them.

A QUICK WALKTHROUGH

How to use this tool

  1. Choose a shape and enter the source pan dimensions.
  2. Choose a shape and enter the target pan dimensions.
  3. Use the multiplier to scale ingredient quantities; keep baking time and doneness under review.

Shape

The estimate treats each pan as a simple prism. Round pans use π × radius² × depth; square and rectangular pans use width × length × depth. Use the same unit for every dimension. All three dimensions are required for every shape. Round calculations ignore length; square and rectangular calculations use width and length as entered, without enforcing equal sides.

Recipe multiplier

Target capacity ÷ source capacity gives the recipe multiplier. This is a capacity estimate, not a guarantee of baking time or results.
