Recipe Scaler
Halve, double or rescale a whole recipe, with tidy fractions.
About this tool
Paste a recipe's ingredient list and scale every quantity at once. Halve it, double it, triple it, set any custom multiplier, or scale from the servings it makes to the servings you want. Results come back as clean fractions, so half of 2 teaspoons is 1 teaspoon and half of 3 is 1 1/2, not 1.5.
It understands fractions (1/2, 1 1/2, ½), scales both ends of ranges like "2-3 cloves", and leaves lines without a quantity untouched. Everything runs in your browser, so your recipe stays on your device. To switch a single measurement between cups and grams, use the cooking converter.
Frequently asked questions
- How do I halve a recipe?
- Paste the ingredient list, then hit Halve. Each quantity is divided by two and shown as a tidy fraction, so 2 teaspoons becomes 1 and 3 teaspoons becomes 1 1/2.
- Can I scale to a specific number of servings?
- Yes. Enter how many servings the recipe makes and how many you want, and every quantity is rescaled by that ratio.
- Does it handle fractions and ranges?
- It reads 1/2, 1 1/2 and unicode fractions like ½, and scales both ends of a range such as "2-3 cloves". Lines without a quantity (like "Salt to taste") are left alone.
