Perfectly adjust any recipe to feed your crowd. Scale up for parties or down for intimate dinners × we'll do the math!
Enter a single ingredient amount and select your scaling factor.
Scaling recipes isn't always as simple as multiplying everything. Here's what you need to know for perfect results every time.
Scaling Factor = Desired Servings × Original Servings
Example: Recipe makes 4, you need 10 ? Factor = 10 × 4 = 2.5×
Multiply each ingredient by 2.5
| Measurement | Equivalent | Metric |
|---|---|---|
| 1 pinch | 1/16 teaspoon | ~0.3 mL |
| 1 teaspoon (tsp) | 1/3 tablespoon | 5 mL |
| 1 tablespoon (tbsp) | 3 teaspoons | 15 mL |
| 1 fluid ounce | 2 tablespoons | 30 mL |
| 1/4 cup | 4 tablespoons | 60 mL |
| 1/3 cup | 5 tbsp + 1 tsp | 80 mL |
| 1/2 cup | 8 tablespoons | 120 mL |
| 1 cup | 16 tablespoons | 240 mL |
| 1 pint | 2 cups | 480 mL |
| 1 quart | 4 cups | 960 mL |
| 1 gallon | 16 cups | 3.8 L |
For half recipes: beat an egg, measure by volume (1 large egg × 3 tbsp), and use half. Or use egg yolk only for richness.
1 stick = 8 tbsp = 1/2 cup = 113g. Cutting a stick into 8 pieces gives you tablespoon portions.
Scale yeast by only 75% when doubling. Too much yeast makes bread rise too fast and affects flavor.
Doubled recipes may need 15-20% more time. Halved recipes cook 15-25% faster. Use a thermometer!
Scale chocolate exactly. Unlike spices, chocolate flavor scales linearly. Don't skimp!
Milk, cream, and buttermilk scale exactly. For sour cream or yogurt, scale by 90% for best texture.
Not all recipe ingredients scale linearly. Understanding which elements need special treatment when scaling up or down prevents cooking disasters:
| Ingredient Type | Scaling Rule | Example: ×2 recipe | Caution |
|---|---|---|---|
| Flour, sugar, main proteins | Scale 1:1 | 1 cup ? 2 cups | None |
| Salt | Scale 75% when doubling | 1 tsp ? 1.5×1.75 tsp | Taste and adjust at end |
| Spices & herbs | Scale 50×75% | 1 tsp ? 1.25×1.5 tsp | Extracts: only 50% |
| Baking powder / soda | Scale 75% when doubling | 1 tsp ? 1.5 tsp | Too much causes bitter taste |
| Eggs | Round to whole numbers | 1.5 eggs ? use 2 | Adjust other liquid slightly |
| Yeast (bread) | Scale 1:1 or less | Can use same amount + longer rise | More yeast = faster rise, over-proofing risk |
| Cooking time | Does NOT scale linearly | Double batch: +15×25% time | Always use a thermometer |
