Recipe Scaler

Scale a recipe up or down for more or fewer people

Cooking for six when the recipe serves four? Type in what the recipe is for, how many you want to make and paste the ingredients. Every amount is multiplied for you, including fractions such as 1/2 and 1 1/2.

Start each line with the amount. Fractions such as 1/2 and 1 1/2 are fine.

How to Use It

Put one ingredient on each line, starting with the amount. Lines with no amount, such as "pinch of salt", are left as they are. Fractions can be typed as 1/2 or 1 1/2.

A Worked Example

A recipe for 4 scaled to 6 multiplies everything by 1.5. 200g flour becomes 300g, half a teaspoon of salt becomes 0.75 of a teaspoon and 2 eggs become 3.

Things to Watch

Amounts scale, but cooking does not always. Tin sizes, pan sizes and cooking times may need to change, and strong flavours such as salt, spice and raising agents are best added a little at a time.

Questions about Recipe Scaler

Does it work with fractions?

Yes. You can type amounts as 1/2, 1 1/2 or with a symbol such as ½. They are worked out and shown as decimals, for example 0.75.

Do cooking times change when I scale a recipe?

Often they do. A bigger quantity in a bigger tin can take longer, and a smaller one can take less time. Check the food as it cooks rather than relying on the original time.

Why are some lines not changed?

Lines with no amount at the start, such as a pinch of pepper or oil for frying, are left as they are. Add the amount yourself if you want it scaled.
