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. 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. Paste your ingredients: Copy ingredients from your recipe, one per line. The tool recognizes common formats like "2 cups flour" or "250g butter".
- 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.
Common Scaling Factors
| To Scale From → To | Multiplier | Example |
|---|---|---|
| 4 → 2 servings (halve) | 0.5× | 1 cup → 1/2 cup |
| 4 → 6 servings | 1.5× | 1 cup → 1 1/2 cups |
| 4 → 8 servings (double) | 2× | 1 cup → 2 cups |
| 4 → 12 servings (triple) | 3× | 1 cup → 3 cups |
| 6 → 4 servings | 0.67× | 1 cup → 2/3 cup |
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.
