Understanding Pan Volume in Baking
Why Pan Volume Matters
Pan volume determines how much batter your pan can hold and affects baking time, texture, and rise. Using the wrong pan size can result in overflow, uneven baking, or flat cakes.
Scaling Guidelines
- Your pan is larger than the recipe pan - increase ingredients
- Your pan is smaller than the recipe pan - reduce ingredients
- Your pan is the same size as the recipe pan - use original recipe
- Adjust baking time: larger pans need more time
Sample Calculations
Round Pan: 20cm × 5cm
V = π(10²)(5) = 1,571 cm³
≈ 1.571 L
Rectangle Pan: 20cm × 20cm × 5cm
V = 20 × 20 × 5 = 2,000 cm³
= 2.0 L
Ratio: 2.0 ÷ 1.571 = 1.27x
