Recipe scaler

Paste any ingredient list or pick one of our recipes, set how many servings you need, and every amount is resized for you.

Scaled by 2x
  • 4 cups all-purpose flour
  • 3 tsp baking powder
  • 1 tsp salt
  • 1½ cup milk
  • 4 large eggs
  • Salt and pepper to taste

Lines without a number at the start, like “salt to taste”, stay the same.

How to use the recipe scaler

  1. Paste ingredients with one item per line, or choose a recipe from the list.
  2. Enter how many servings the original recipe makes.
  3. Enter how many servings you want, or tap Half, 2x or 3x.
  4. Copy the resized list or read it straight from your phone while you cook.

What it understands

Whole numbers (2), decimals (2.5), fractions (3/4), mixed numbers (1 1/2), fraction symbols (1½) and ranges (2 to 3). Results are rounded to kitchen friendly fractions such as ¼, ⅓ and ½.

Tips for scaling baked goods

  • Weigh flour and sugar when you scale up. Small measuring errors grow with the batch. Our cups to grams converter helps.
  • Change the pan size to match. Doubling a recipe in the same pan makes it twice as thick and slower to bake.
  • Leaveners like baking soda scale normally for 2x. For very large batches, mix in two separate bowls.

Frequently asked questions

How do I double a recipe?

Enter the servings the recipe makes, then press 2x. Every ingredient with a number at the start of the line is multiplied by two. Baking time usually needs to increase slightly for a larger pan, so check doneness rather than relying on the original time.

Can I scale a recipe down to one or two servings?

Yes. Set the new servings to 1 or 2. For eggs, the scaler may give an amount like 1/2 egg; beat one egg and use about half (roughly 25 g).

Do I need to change cooking times when scaling?

Often a little. Bigger batches in deeper pans take longer, and smaller batches cook faster. Keep the same oven temperature and check early.

What about spices and salt?

They scale in the list like everything else, but when tripling or more, start with about three quarters of the scaled amount and season to taste at the end.
