Recipe Scaling Calculator

Enter the original and desired yield to get a multiplier for every ingredient.

4 to 6 servingsMultiply ingredients by 1.5×
  • Cooking fraction: 1 1/2×

Multiply every ingredient amount by the scale factor. Cooking time, pan size, and seasoning may still need adjustment.

Quick answer

Desired yield ÷ original yield = scale factor. Multiply each ingredient amount by that factor.

Scaling formula

Divide the desired yield by the original yield. Multiply every ingredient amount by that scale factor, then assess pan size, cooking time, and seasoning separately.

Practical examples

Measurement notes

Ingredient amounts scale mathematically, but pan size, bake time, seasoning, yeast, and other leavening may need practical judgment.

Common question

Should I scale cooking time by the same factor?

Usually not. Start checking doneness earlier or later as appropriate, because cooking time depends on pan shape, depth, heat, and ingredients.
