CalcCoreWhy you need a recipe scaler
Recipes are often written for a specific number of servings that may not match your situation — for example, a recipe for 4 people when you have 8 guests, or the opposite — you need to cook less for one person. Manually recalculating every ingredient takes time and is easy to get wrong.
How the scaling works
The calculator computes a scaling factor as the ratio of desired servings to original servings (for example, 6 servings instead of 4 = a 1.5x factor), then multiplies each ingredient amount by that factor.
What you should still adjust manually
- Spices and seasonings: when significantly scaling up a recipe, it's better to add spices gradually and taste rather than scale them exactly proportionally.
- Leavening agents (baking soda/powder): in large quantities they can add a bitter taste — it's recommended to slightly reduce the proportion when significantly scaling up.
- Cooking/baking time: doesn't scale linearly! Doubling a recipe doesn't mean doubling the oven time — a larger pan or more food requires separate doneness checks.
- Baking pan size: when changing the number of servings, you'll likely need to change the pan size too.
For best results, write ingredients in the format "amount + unit + name" (e.g. "2 cups flour") so the calculator can correctly detect the number to scale.
FAQ
How do I use the recipe scaler?
Enter each ingredient with its amount on a separate line, specify the original and desired number of servings — the calculator will automatically scale all amounts proportionally.
Do all ingredients scale the same way?
The calculator scales all amounts proportionally, but note: spices, salt, leavening agents, and cooking time don't always scale linearly — adjust them to taste.
Can I enter fractional numbers?
Yes, you can enter both whole numbers and decimals (e.g., 1.5 cups).
