How do I scale a recipe to a different number of servings?

Divide the target servings by the original servings to get a multiplier, then multiply every ingredient by it. To take a 4-serving recipe to 6, the multiplier is 6 ÷ 4 = 1.5, so every quantity goes up by half. The scaler does this for you and rounds each result to a measurable amount.

Does scaling work for baking?

It works for the ingredient quantities, but baking has limits. Pan size, bake time and leavening do not scale in a straight line, so a doubled cake will not simply take twice as long. For big changes, weigh ingredients in grams first and check the bake early. The pan converter helps with the tin size.

Can I scale by weight as well as volume?

Yes. The scaler multiplies whatever number it finds at the start of a line, whether that is cups, grams, millilitres or whole eggs. For accuracy in baking, convert your cups to grams first, then scale, so the rounding stays clean.

Your recipe

Scaled

4 cups all-purpose flour 2 cup granulated sugar 1 cup butter, softened 4 large eggs 2 tsp vanilla extract 1 tsp salt 2 cup milk

Quantities snap to common kitchen fractions. Lines with no leading number, like "a pinch of salt", pass through unchanged.

How to use it

1
Paste your ingredients

One ingredient per line, like "2 cups flour" or "1 1/2 tsp salt". The scaler reads the quantity at the start of each line.
2
Set the new size

Enter original and target servings, or just type a multiplier like 0.5 to halve or 2 to double.
3
Copy the scaled list

Read the resized quantities, rounded to amounts you can actually measure, and copy the whole list.

When it comes in handy

Cooking for a crowd

Take a recipe that serves four and resize it to serve ten without doing the maths by hand.

Halving a big batch

Cut a recipe down when you only want a small amount, with the fractions handled for you.

Matching what you have

Scale a recipe to the amount of a key ingredient you actually have in the cupboard.
