Frequently Asked Questions

Common questions about Recipe Scaling Calculator, formulas, and typical use cases.

How do you scale a recipe by servings?

Use a multiplier equal to target servings divided by original servings, then multiply each ingredient by that factor.

Can this scale recipes down as well as up?

Yes. When target servings are smaller than original servings, the multiplier is less than 1.

Should all ingredients be scaled equally?

Most ingredients scale directly, but spices, leavening, and cooking times may need adjustment by taste and technique.

Why include percent change?

Percent change helps quickly understand how much larger or smaller the new batch is versus the original.
