Volumes are calculated from each pan's inside dimensions, assuming straight sides. Real pans with sloped sides hold about 10 to 15% less. Bundt and muffin pans use their rated capacity.
Ingredient scaling
Leavening note: Bigger, taller cakes baked in one pan need proportionately less baking powder and baking soda. For a scale factor above 1.5x, a common starting point is about 10 to 15% less than the calculated amount. There is no exact rule, so test.

Baking conversion tips
- In a smaller pan, the batter will be deeper, so lower the oven temperature by 25°F and allow more baking time. Start checking doneness at the original time.
- When moving to a larger pan, batter will be shallower, so bake time is usually shorter. Check 10 min earlier.
- Bundt pans suit most butter and oil cakes. The batter sits deeper, so a Bundt cake bakes longer than the same batter in a 9x13 pan.
- Cheesecakes are usually baked in a springform pan so they can be unmolded cleanly; in another pan, line it with parchment.
- Always test doneness with a toothpick or skewer. It should come out clean or with a few moist crumbs.
- For fractions of eggs, either round to the nearest whole egg and adjust the other wet ingredients slightly, or beat the eggs and measure them using about 3 tablespoons per large egg.
- A 9" round pan and an 8" square pan have nearly identical areas, so you can swap them without changing the recipe.
