Recipe Scaler (Change Servings and Scale Ingredients)

How to use the Recipe Scaler (Change Servings and Scale Ingredients)

1. Paste the ingredients, one per line.
2. Enter how many servings the recipe makes and how many you need.
3. Read the scaled list and copy it. Fractions are shown as, for example, 1 1/2.

Example

Worked example (recipe for 4, scaled to 6, factor × 1.5)

• 2 cups plain flour: 3 cups plain flour
• 1 1/2 tsp salt: 2 1/4 tsp salt
• 3 eggs: 4 1/2 eggs (use 4 or 5, or beat one and use part of it)
• 1/3 cup oil: 1/2 cup oil
• 250 g butter: 375 g butter
• salt to taste: unchanged

Limitations

• Only a number at the start of a line is scaled. Numbers in the middle, such as “a 400 g tin”, stay as they are.
• Unit changes are not made, so 16 tbsp stays as tablespoons.
• Salt, spices, raising agents, baking times and pan sizes do not always scale in a straight line.
• Fractions are rounded to the nearest eighth, third or two-thirds when within 0.02, otherwise shown as a decimal.

About this tool

The Recipe Scaler multiplies the quantities in a recipe to suit the number of people you are cooking for. Paste one ingredient per line, enter how many servings the recipe makes and how many you want, and it scales each leading number, including fractions such as 1 1/2 or ½. Lines without a number, like “salt to taste”, are left alone. Results are shown as neat fractions where they are close to one.
