Free Recipe Pan Converter

Baking a recipe in a different pan? Enter the recipe's pan and the one you'd like to use — get the exact coefficient to multiply every ingredient by. Same batter height, different pan size.

Unit
How this works

The coefficient is the ratio of pan areas: target area ÷ source area. Multiply every ingredient in the recipe by this number to bake the same batter at the same height in your pan.

Example: recipe ø26 cm → your rectangular pan 12×12 cm

Source area = π × 13² ≈ 531 cm² · Target area = 12 × 12 = 144 cm² · Coefficient = 144 ÷ 531 ≈ 0.271

Bake at the same batter height as the original recipe.

Quick lookup tables

Skip the calculator when the numbers are round: find your row, slide across to the recipe's column, and multiply every ingredient by the coefficient. Same math as above — just precomputed for the cake-pan sizes you'll actually use.

Round-pan diameter swap

For round cakes baked at the same height as the recipe. Coefficient = (your diameter ÷ recipe diameter)².

Tier-height swap

For the same diameter at a different tier height — taller layer cake, shorter sheet, etc. Coefficient = your height ÷ recipe height.
