Calculators
Scale recipe ingredients up or down for any number of servings. Enter original servings and ingredients, set your desired servings, and get perfectly scaled quantities for every ingredient.
Follow these simple steps to get instant, accurate results directly in your browser:
Input the current serving count stated in your recipe (e.g. 4 servings).
Specify the number of servings you want to prepare (e.g. 10 servings).
Type or paste your ingredient list to instantly view perfectly scaled quantities.
The Recipe Scaler scales culinary ingredient quantities up or down to match any desired serving size, pan dimension, or guest count.
Cooking for a dinner party of 12 using a recipe designed for 4—or halving a dessert recipe designed for 8—requires scaling ingredient proportions accurately while preserving cooking ratios. The tool converts decimal quantities into intuitive culinary fractions (such as 1/2 tsp, 3/4 cup, 1 1/3 tbsp) for ease of use in the kitchen.
All conversions execute locally in your web browser session. Your favorite recipes and baking formulas remain private.
Scale Factor = Target Servings / Original Servings | Scaled Quantity = Original Quantity * Scale FactorEvery ingredient quantity is multiplied by the scale factor ratio to maintain exact flavor balances.
Original Recipe = 4 Servings | Desired Servings = 10 Servings Scale Factor = 10 / 4 = 2.5 Ingredient: 2 cups of flour -> 2 * 2.5 = 5.0 cups of flour Ingredient: 1.5 tsp of vanilla extract -> 1.5 * 2.5 = 3.75 tsp (3 3/4 tsp).
Our calculation methodologies adhere to published guidelines from authoritative government agencies and standards bodies:
