Paste your ingredient list, choose the original and new number of servings, and scale the quantities instantly.
1. Add your recipe
Tip: put the quantity at the start of each ingredient line. Headings and notes without a starting quantity are kept unchanged.

HOW IT WORKS
Scale a Recipe Without Doing the Math
The Recipe Scaler adjusts ingredient quantities to match the number of servings you want. Enter the recipe’s original serving size, choose your new serving size and the calculator applies the same scaling factor to every quantified ingredient.
You can paste a whole ingredient list at once. Lines such as section headings or ingredients without a fixed quantity, including “salt to taste”, are left unchanged.
A Quick Example
A recipe serves 4, but you need 6.
1 1/2 cups flour → 2 1/4 cups
3/4 cup milk → 1 cup + 2 tablespoons (tbsp)
2 eggs → 3 eggs
2 tablespoons (tbsp) butter → 3 tablespoons (tbsp)
Scaling factor: ×1.5
Designed for Real Kitchen Quantities
Fractions Stay Practical
The scaler understands decimals, ordinary fractions and mixed fractions. Where useful, awkward cup measurements are rewritten into quantities that are easier to measure, such as 1 cup + 2 tablespoons (tbsp).
Metric Ingredients Work Too
Ingredients written in grams, kilograms, milliliters and other metric units can be scaled normally. For example, 400 grams (g) scaled by ×1.5 becomes 600 grams (g).
Half an Egg?
Sometimes scaling produces part of an egg. When the result is a half egg, the scaler presents it as a beaten-egg quantity, for example 4 eggs + 1/2 beaten egg.
Scaling and Converting Are Different
The Recipe Scaler changes the quantity while keeping the original measurement unit. It does not automatically turn cups into grams or ounces into milliliters.
If you also need to change measurement systems, use the Cooking Converter. Its ingredient-aware conversions account for the fact that a cup of flour does not weigh the same as a cup of butter.
CHANGING YOUR PAN?
Serving Size Isn’t the Only Reason to Scale a Recipe
Changing the size or shape of a cake pan or baking pan can also change how much mixture you need. Comparing pan areas first gives you a much better scaling factor than simply guessing.
What the Scaler Doesn’t Change
- Oven temperature
- Cooking or baking time
- Pan dimensions
- Cooking method
- Ingredients without a numeric quantity
Large changes in recipe size can affect cooking time, so use the original recipe as a guide and check for doneness as you cook.
Recipe Scaler FAQs
Can I scale a recipe using grams and milliliters?
Yes. Metric quantities can be scaled in exactly the same way as cups, tablespoons or ounces. The scaler keeps the original unit and changes the numerical quantity.
Does the Recipe Scaler convert cups to grams?
No. Scaling and unit conversion are separate jobs. Use the Cooking Converter when you need to change cups to grams, ounces to grams, Fahrenheit to Celsius or other cooking measurements.
Can it scale ingredient ranges?
Yes. Simple ranges such as “2–3 tablespoons (tbsp) olive oil” are scaled at both ends of the range.
What happens to ingredients such as “salt to taste”?
Lines without a numerical quantity are kept unchanged. The same applies to recipe-section headings such as “For the topping”.
Should I change the oven temperature when scaling a recipe?
Usually the recipe’s stated temperature remains the starting point. However, changing the amount of food or the size and shape of the pan can affect cooking time. Check the food as it cooks rather than relying only on the original timing.
Need to Change More Than the Servings?
Convert measurements or work out how much mixture you need for a different baking pan.
