Page guide

Resize your ingredient list for more or fewer servings, including fractions and mixed numbers.

How to use Recipe scaler
  1. Enter the original and target servings. Add one ingredient per line as quantity, ingredient, for example 1 1/2, cups flour. The quantities scale together and the units stay as you wrote them. Copy or download the resized list.
  2. Scaling a four-serving recipe to ten servings multiplies quantities by 2.5. One and a half cups of flour become 3.75 cups, half a teaspoon of salt becomes 1.25 teaspoons and two eggs become five.
