Recipe Scaler — Resize Any Recipe
Double a recipe for a crowd, halve it for two, or scale it to any number of servings. Paste the ingredient list and every amount is recalculated with tidy kitchen fractions.
How to scale a recipe
- Enter how many servings the original recipe makes and how many you want.
- Paste the ingredient list, one ingredient per line. Amounts like 1 1/2, ¾, 0.5 and ranges like 2-3 are recognized.
- Copy the scaled list. Use the quick buttons to halve, double or triple.
Tips for scaling recipes
Most ingredients scale in a straight line, and this tool rounds results to fractions you can actually measure (⅛, ¼, ⅓, ½, ⅔, ¾). When the result is an awkward amount like 2⅔ eggs, round to the nearest whole egg or beat an egg and use part of it.
Some things do not scale perfectly. Leaveners (baking soda and powder), salt and strong spices can taste too strong when a recipe is multiplied several times, so many bakers increase them a little less. Pan size changes baking time: a double batch in a larger pan usually needs more time at the same temperature, while splitting it between two pans keeps the time similar.
For very large or very small changes, consider converting to weight. Our cooking converter turns cups and spoons into grams, which scale more accurately than volume measures.

Frequently asked questions
Can I scale by a factor instead of servings?
Yes. Set original servings to 1 and new servings to the factor (for example 1.5), or use the ½×, 2× and 3× buttons.
What formats does it understand?
Whole numbers, decimals, fractions (1/2), mixed numbers (1 1/2), unicode fractions (½) and ranges (2-3).
Does it convert units?
It scales amounts but keeps your units. Use the cooking converter to switch between cups, grams and spoons.
Should I scale baking times?
Not directly. Times depend on pan size and depth; check for doneness early.
