Recipe scaling formula
Scale factor = desired servings / original servings
New ingredient amount = original amount x scale factor
This works best for simple ingredient quantities. Spices, salt, leavening, pan size and cooking time may need judgment when scaling very large or very small batches.
Recipe scaling tips
- Round ingredient quantities to a practical kitchen measurement.
- Scale salt and strong spices carefully, then adjust to taste.
- For baking, keep ratios precise and check pan depth.
- Cooking time may not scale directly with servings.
Recipe Scaler FAQ
How do I scale a recipe?
Divide desired servings by original servings, then multiply each ingredient quantity by that scale factor.
Can I double a recipe with this tool?
Yes. Set desired servings to twice the original servings, or simply use a scale factor of 2.
Do spices scale exactly?
Not always. Strong spices, salt and leavening agents often need taste or recipe-specific adjustment.
Does cooking time scale with servings?
Usually not directly. Larger batches can need more time, but pan size and food thickness matter more.
Can I use metric and US units?
Yes. The calculator scales the numeric quantity and keeps the unit label you enter.
