Scale recipe ingredients up or down by servings with smart fractional rounding.
Recipe scaling is the process of adjusting ingredient quantities to change the number of servings a recipe yields. A scale factor is calculated by dividing desired servings by the original, then multiplying each ingredient amount.
Scale factor: ×2.00
Formula
Scaled Amount = Original Amount × (Desired Servings ÷ Original Servings)Original Amount = ingredient quantity in the base recipe
Scale Factor = Desired Servings ÷ Original Servings
Worked Example
Scale flour from 4 to 6 servings
Did you know? Leavening agents like baking powder and yeast don't scale linearly for very large batches — for a 4× batch, use only 3× the leavening to avoid an overly airy or collapsed texture.
