Recipe Scaler
Resize recipe quantities from the original servings to the batch you want to make.
Use decimals or recipe fractions such as 1 1/2.
Original servings are the recipe yield as written; desired servings are the batch size you want to make.
Enter serving counts and an ingredient amount.
Scaling Tips
A scale factor works well for most quantities, but some recipe details need judgment.
Leavening
Baking powder, baking soda, and yeast may not always scale perfectly for very large changes.
Seasoning
Salt, spices, chili, and extracts often need tasting rather than blind multiplication.
Pan size
When baking, pair serving scaling with pan-area scaling to keep batter depth close to the original.
Recipe Scaler FAQ
Common questions about changing batch sizes.
How does recipe scaling work?
The calculator divides desired servings by original servings to get a scale factor, then multiplies each ingredient amount by that factor.
Can I enter fractions?
Yes. Ingredient amounts can use common recipe formats such as 1 1/2, 3/4, 2-1/4, or decimals.
Do all ingredients scale perfectly?
Most ingredient quantities scale linearly, but salt, spices, leavening, cooking time, and pan size may need judgment for very large or very small batches.
