Recipe Scaler

Scale any recipe up or down. Paste your ingredients and we'll calculate the new amounts for your desired servings.

Supported formats: "2 cups flour", "1/2 cup sugar", "250g butter", "1 1/2 tsp salt"

How to Use the Recipe Scaler

  1. 1. Choose your scaling method:
    • By Servings: Enter how many servings the original recipe makes and how many you want
    • By Multiplier: Enter a number like 2 to double or 0.5 to halve
  2. 2. Paste your ingredients: Copy ingredients from your recipe, one per line. The tool recognizes common formats like "2 cups flour" or "250g butter".
  3. 3. Click "Scale Recipe" to see the new amounts displayed as fractions for easy measuring.

Tips for Scaling Recipes

Use Weight Measurements

Scaling works best with weight (grams/ounces) rather than volume (cups). Consider converting your recipes to weight for more accurate scaling.

Adjust Leaveners Carefully

Baking powder, baking soda, and yeast don't always scale linearly. When doubling, use 1.5x to 1.75x the leavener amount.

Consider Pan Size

Doubling a recipe often means using a larger pan or multiple pans. This affects baking time and heat distribution.

Test Before Big Batches

If scaling a recipe significantly (4x or more), test with a smaller batch first to check that it still works well.

Frequently Asked Questions

To scale a recipe, divide your desired servings by the original servings to get a multiplier. Then multiply each ingredient amount by that number. Our calculator does this automatically - just enter your original and desired servings.
