Recipe Scaling Calculator by Pan Size
Scale a recipe by comparing the base area of the new pan with the base area of the original pan. A 10-inch round pan has about 56% more surface area than an 8-inch round pan, so the ingredient quantities should be multiplied by roughly 1.56 when the desired depth stays the same.
Planning estimate only. Check measurements and real-world constraints before buying materials or making a commitment.

Worked example
Use this example to check the calculator by hand before relying on a result.
Assumptions behind the result
- • Measurements use the inside of each pan.
- • Batter depth stays the same.
- • Both pans use the same basic shape approximation.
- • Ingredient ratios do not change.
- • Bake time is not scaled linearly.
Mistakes that change the answer
- • Comparing diameters instead of areas.
- • Using outside pan measurements.
- • Multiplying oven temperature by the scale factor.
