Recipe Scaler
Scale a recipe up or down for a different number of servings.
Adjusting the quantities
Cooking for a different number than a recipe serves means scaling every ingredient by the same factor — double for twice the people, halve for half. This scales a recipe's quantities to your target servings, so you get the right amount of everything without working out each ingredient by hand.
Enter the original servings and your target to scale the ingredients.
What doesn't scale linearly
Ingredient quantities scale cleanly, but a few things do not, which is worth knowing so a scaled recipe still works. Cooking times and pan sizes do not simply double — a larger quantity in a bigger dish may need longer or a different temperature, and a doubled cake will not bake right in the same tin. Strong seasonings like salt, spices and raising agents sometimes need a slightly lighter hand than a straight scaling, and very small measures round awkwardly.

Does everything scale exactly?
Ingredients do, but strong seasonings and raising agents sometimes need a slightly lighter hand when scaling up, and tiny measures round awkwardly.
