💡 Baking tip
When scaling baking recipes, note that leavening agents (baking powder, baking soda, yeast) should not always scale linearly. For recipes scaled more than 2×, reduce leavening by about 10–15% and test.
Frequently Asked Questions
Can I scale a recipe up and down?
Yes. Enter any original serving count and any target count — the tool scales in either direction. Use 0.5 for half a serving or enter a decimal like 2.5.
Do baking recipes scale accurately?
Most ingredients scale directly, but leavening agents (baking powder, baking soda, yeast) are an exception — they don't always scale 1:1 for large batches. Our tip section warns you when this applies.
What units can I use?
The scaler works with any text units — cups, tablespoons, grams, ounces, ml, or even counts like '2 eggs'. Simply type the unit and the calculator scales the number.
Why does the result show as a fraction?
Fractions like ¾ cup are easier to measure than decimals like 0.75 cups. The scaler converts decimals to the nearest practical fraction for easier cooking.
