How do I scale a recipe to a different number of servings?

Enter the original servings and the number you want. The scaler divides the new servings by the original to get a scale factor, then multiplies every ingredient by it. A recipe for 4 scaled to 6 servings multiplies everything by 1.5.

Can I scale a recipe and convert cups to grams at the same time?

Yes. Use the recipe scaler to resize servings, then use the unit converter on this page to switch between cups and grams, ounces and grams, or °F and °C. To do both automatically from a recipe URL, use the Drizzlelemons recipe converter.

Is the recipe scaler free?

Yes. The recipe scaler and unit converter on this page are completely free to use with no sign-up required.

Q: How do I double a recipe?

To double a recipe, multiply every ingredient quantity by 2. Enter your ingredients into the recipe scaler above and tap "double" (or set the scale factor to 2x) and every amount updates instantly, including fractions like 1½ cups becoming 3 cups.

Q: How do I halve a recipe?

To halve a recipe, divide every ingredient by 2. Paste your ingredients into the scaler and choose half (0.5x). It handles awkward fractions for you — for example, ¾ cup becomes 6 tablespoons — so you do not have to do the math in your head.

Double a recipe, halve it, or resize it to any number of servings — and every ingredient quantity updates instantly. Free, no sign-up.

A recipe scaler takes a recipe written for one number of servings and rewrites every ingredient amount for the number you actually want to cook. Enter your ingredients below, set the new serving size, and the calculator does the proportional math for you — including the fiddly fractions.

How to Scale a Recipe (the Simple Math)

Scaling a recipe comes down to one number: the scale factor. Divide the servings you want by the servings the recipe makes, then multiply every ingredient by that factor.

Double (2×)

Cooking for a crowd or meal-prepping the week? Multiply everything by 2. 1½ cups flour becomes 3 cups; 2 eggs become 4.

Halve (0.5×)

Cooking for one or two? Divide by 2. The scaler turns awkward amounts like ¾ cup into 6 tablespoons so you don't have to.

Any servings

Recipe makes 4 but you need 6? The scale factor is 6 ÷ 4 = 1.5. Multiply each ingredient by 1.5 and you're set.

Scaling Tips Most Calculators Miss

Pan size matters. Doubling a cake batter rarely means doubling the bake time — use a larger pan or two pans and check doneness early.
Seasoning isn't always linear. Salt, spices, and leavening (baking soda/powder) can taste over-strong when scaled up. Scale, then taste and adjust.
Eggs don't halve neatly. When halving, beat one egg and use half by weight, or pick the nearest whole number for forgiving recipes.
