Recipe Scaling Calculator
Scale recipe ingredients by serving count. Enter each ingredient on its own line starting with quantity (e.g., "2 cups flour").
Scaled Ingredients (×1.500)
3 cups flour 1.5 cup sugar 4.5 tbsp butter 2.25 tsp salt
For baking, don't simply scale spices and salt — those need finer adjustment. Pan size: area scales as diameter². Halving a 9" cake recipe needs a ~6" pan, not 4.5".
