Recipe Scaler

Multiply or divide recipe ingredient amounts by serving size with fraction-friendly output for cooking and baking.

O M T

Scale recipe servings quickly

Doubling a dinner party menu or halving a batch cookie recipe means multiplying every measured ingredient. This scaler adjusts quantities when each line begins with a number, fraction, or mixed number such as 1 1/2 cups milk.

How scaling works

Enter original servings and target servings. The tool multiplies each leading amount by the ratio target divided by original. Lines without a leading number stay unchanged, which is useful for headers like "For the glaze".

Frequently Asked Questions

Does it understand cups and grams?

It scales the numeric part only. Units stay attached, so 2 cups becomes 4 cups when you double servings. It does not convert weight to volume.

What fractions does it print?

Results round to common kitchen eighths when possible, such as 1/2 or 1 3/4.

Can I scale baking by pan size?

This tool scales by serving count, not pan area. For area-based scaling, adjust servings to match the volume change you need.

Will spice amounts stay accurate?

Very small amounts may round to zero. Taste and adjust seasonings after scaling, especially for salt and chili.
