Recipe Scaler

Scale a recipe up or down without breaking it.

Scaled recipe
  • 4.00 cups all-purpose flour
  • 1.74 tsp saltsub-linear scaled
  • 1.80 tsp baking sodasub-linear scaled
  • 1.50 cup sugar
  • 4.00 eggs
  • 1.00 cup butter

Salt, baking soda, baking powder, and yeast scale sub-linearly so the result tastes right.

About

Doubling a recipe doesn't always mean doubling everything. Salt, leavening, and spices scale non-linearly. This scaler uses smarter coefficients for those ingredients so a 4x cookie recipe doesn't end up 4x salty.

How to use

  1. Paste your ingredient list (one per line, e.g. '2 cups flour').
  2. Pick a target multiplier (0.5x, 2x, 3x, custom).
  3. See the scaled list with smart adjustments for salt, baking soda, baking powder, and yeast.

FAQ

Why don't salt and leavening scale linearly?+

Salt is taste-driven and saturates non-linearly. Leavening produces gas, and the amount needed grows sub-linearly with batter volume. Pro bakers' doubled bread recipes use about 1.7x salt and 1.5x yeast, not 2x.
