CALCULATOR GUIDE
How to use the Recipe Scaler
Scale ingredient quantities by target servings or by a direct recipe multiplier.
Worked example
Changing a four-serving recipe to ten servings uses a 2.5× scale factor, so 2 cups becomes 5 cups.
Assumptions and limits
Seasonings, leavening, pan capacity and cooking time may not scale perfectly in a straight line.
Frequently asked questions
Can every ingredient be scaled equally?
Weights and volumes can be multiplied directly, but spices, leavening and cooking times may need judgment.
How do I halve a recipe?
Use a 0.5 multiplier or set target servings to half the original servings.
