How to use the chart
- Swapping pans: pans listed as "about the same" are within 8% in area, close enough for most cakes and bakes.
- Scaling: to move a recipe between any two pans, multiply it by (new pan area ÷ old pan area), or use the pan size converter.
- Loaf pans have sloped sides, so their bottom area understates how much they hold; treat loaf conversions as approximate.
Keep the batter depth similar and baking times stay similar; check doneness a few minutes early in a larger pan.
Frequently asked questions
What pan is the same as a 9-inch round?
An 8" square (64 sq in) is practically the same as a 9" round (63.6 sq in).
Can I use two 9-inch rounds instead of a 9×13?
Two 9" rounds have about 127 sq in versus 117 sq in for a 9×13, so the batter will be slightly thinner. That usually works; check for doneness a little early.
