Methodology

How we calculate this

Methodology reviewed September 2026

Every scalable ingredient is multiplied by the ratio between the desired yield and original yield.

The math

  • Scale factor = desired servings ÷ original servings
  • New ingredient quantity = original quantity × scale factor

Worked example

Scaling a 4-serving recipe to 10 servings gives a factor of 2.5. One cup becomes 2½ cups.

Frequently asked questions

Helpful answers

How much chili should I make for 18 people?

For a main dish, plan about 1 to 1½ cups per person. Use the lower end with substantial toppings and sides and the higher end for hungry guests or leftovers.

How much dry pasta should I buy per person?

Plan about 2 ounces of dry pasta per person as a side or 3 to 4 ounces as a main, then adjust for appetites and the number of other courses.

Does doubling a recipe always double the cooking time?

No. Ingredient quantities double, but cooking time depends on pan depth, surface area, and heat transfer. Use visual cues and internal temperature where appropriate.
