About this tool
The Recipe Ingredient Scaler resizes any recipe up or down to a new number of servings. Paste your ingredient list, set the original and target servings, and every quantity gets recalculated and rounded to a kitchen-friendly fraction (eighths, not decimals) so the result actually reads like a real recipe.
It handles whole numbers, simple fractions like “1/2”, and mixed numbers like “1 1/2” – useful for doubling a dinner recipe, halving a batch of cookies, or scaling a recipe from a 4-serving card up to feed a crowd.
How to use it
- Enter how many servings the original recipe makes.
- Enter how many servings you want instead.
- Paste your ingredient list, one item per line, with the quantity first.
- Read the scaled list in the output box – quantities are rounded to the nearest 1/8 for practical measuring.
Pro tips
- Scaling spices, salt, and leavening (baking powder/soda) linearly does not always taste right at large multiples – start a bit lower and adjust to taste for anything scaled beyond 2x.
- Baking recipes scale most reliably by weight rather than volume – if your recipe lists grams, the scaling math is more accurate than with cups and spoons.
FAQ
Why did some of my lines not scale?
The tool needs a number at the start of the line (like “2 cups” or “1/2 tsp”). Lines like “salt to taste” or “a pinch of cinnamon” have no quantity to scale, so they pass through unchanged.
Does it convert units, like cups to grams?
No – it only scales the quantity you already used, keeping the same unit. For unit conversion, use the Volume Converter or Weight Converter below.
