Baking pan converter
Scale a recipe between round or rectangular baking pans.
A clear answer. Here’s how.
Compares base areas, assuming the same batter depth and the same length unit throughout. Multiply ingredients by new area ÷ original area. This does not determine baking time, pan capacity or safe fill depth.

- Original pan shape
- Round
- Original diameter or width
- 20
- New pan shape
- Round
- New diameter or width
- 24
Example result
- Multiply ingredients by
- 1.44
- Original base area (square units)
- 314.159265359
- New base area (square units)
- 452.389342117
Assumes the same batter depth. Check baking time and fill depth separately.
