A little science. A lot of good food.
Your pan. The right amount.
Convert round and rectangular cake pan sizes using inside dimensions, pan counts and batter depth. Transfer the multiplier to your recipe.
THE SECRET INGREDIENTA little precision.
A good fit starts with the footprint.
Straight-sided pans, inside dimensions, room for the rise.
02 / The recipe multiplier
Area and intended batter depth give a geometric starting point. They do not determine a precise baking time. Sources & assumptions ↗
A pinch of know-how
Make space
for a good rise.
Match the batter, then leave the headroom your recipe needs.

8-inch round → 9-inch round
With the same batter depth, multiply by 81 ÷ 64 = 1.265625. A 200 g ingredient becomes 253.125 g before practical rounding.

Area isn’t a baking clock.
Deeper batter and different materials change how a cake sets. Follow recipe guidance and check doneness.
