How Recipe Scaling Works

Recipe scaling uses a simple ratio calculation. By dividing your desired servings by the original servings, you get a scaling factor that's applied to every ingredient. This ensures all proportions remain balanced for perfect results.

Formula

The scaling calculation is straightforward:

1. Calculate Scaling Factor

`Scaling Factor = Desired Servings ÷ Original Servings`

2. Scale Each Ingredient

`New Amount = Original Amount × Scaling Factor`

Example

Original: 4 servings, need 6 servings Scaling Factor = 6 ÷ 4 = 1.5 If recipe calls for 2 cups flour: New Amount = 2 × 1.5 = 3 cups flour

Key Terms

Frequently Asked Questions

Q:Can I scale recipes down to fractions of servings?

Yes! Our calculator supports any serving size, including fractions. However, for very small quantities (like 0.5 servings), be mindful that some measurements may become impractical (e.g., 0.25 eggs).

Q:Do I need to adjust cooking time when scaling?

Cooking times don't scale linearly. A doubled recipe may need 20-30% more time, not double. Always check for doneness using visual cues, internal temperature, or the toothpick test rather than relying solely on time.

Q:Should spices be scaled the same as other ingredients?

Not always. Spices and strong flavors can be overwhelming if doubled directly. Start with less than the scaled amount and taste as you cook. You can always add more.

Q:What if the scaled ingredient amount is awkward (like 2.7 eggs)?

Round to practical measurements. For eggs, 2.7 can become 3 whole eggs, or 2 whole eggs plus 1 egg white. For dry ingredients, round to the nearest convenient measuring increment (e.g., 2.7 cups → 2¾ cups).
