Scale a recipe to the servings you need
Enter the original and wanted servings, then add each measured ingredient. The calculator multiplies quantities; pan size, cooking time, and seasoning still need your judgment.
Free, no account needed. Calculations run in your browser. Inputs are not saved; copy or download before leaving. Example values are illustrative.
Replace the example ingredients. Amounts accept 1.5, 1/2, 1 1/2, or ½. Use a decimal point. For “2 × 400 g cans,” enter 2 as the amount and “400 g cans” as the unit; the package size stays unchanged.
1.5× the original quantities

What to check before cooking
A factor of 1.5 turns 300 g into 450 g and 1½ tablespoons into 2¼ tablespoons. It doesn't turn a 20-minute bake into 30 minutes. Check pan capacity, batter depth, and the recipe's doneness cues separately.
Keep “salt to taste” and other unmeasured instructions in your method. Quantities aren't converted between cups and grams. A fraction of an egg or a can needs a practical measuring decision, and scaled versions should be tested before you recommend them to readers.
Compare cake-pan sizesKeep the checked recipe with your notes
Record the quantities you used and what happened when you cooked them. A calculated variation still needs a cook-through before it becomes a recommendation.
