Recipe Converter
Scale any recipe up or down instantly. Enter your original and desired servings, and watch all ingredient amounts update automatically.
Quick Answer
To scale a recipe, divide the desired servings by the original servings to get a multiplier. Multiply every ingredient amount by that number. For example, doubling a recipe that serves 4 to serve 8: 8 ÷ 4 = 2, so use 2× every ingredient. This calculator handles fractions like 1/4, 1/3, and 2/3 cup automatically.

About This Tool
The Recipe Converter helps you scale any recipe to the number of servings you need. Whether you are cooking for two or preparing a dish for a holiday gathering of twenty, this tool recalculates every ingredient amount automatically. It handles whole numbers, decimals, and common cooking fractions such as 1/4, 1/3, 1/2, 2/3, and 3/4 cup.
How Recipe Scaling Works
Recipe scaling uses a simple ratio. Divide the number of servings you want by the number the recipe originally makes. That gives you a multiplier, sometimes called a scaling factor. Multiply every ingredient quantity by that factor. For instance, if a recipe serves 4 and you need 6 servings, the multiplier is 1.5. An ingredient listed as 2 cups becomes 3 cups.
Working with Fractions
Cooking measurements frequently use fractions. This calculator understands inputs like "1/4", "1/3", "2/3", and even mixed numbers like "1 1/2". The results are displayed as friendly fractions when possible so you can measure with standard kitchen tools. If a scaled amount does not align with a common fraction, the tool shows a decimal rounded to two places.
Tips for Successful Scaling
While ingredient amounts scale linearly, some elements of cooking do not. Baking times may need slight adjustment. Spices and salt should be scaled conservatively and adjusted to taste. Leavening agents like baking powder and yeast do not always scale in a straight line. For yeast breads, increase yeast by about 75% when doubling a recipe rather than a full 100%. Pan sizes also matter: doubling a recipe may require a larger pan or two pans to maintain proper thickness.
Common Scaling Scenarios
Half recipes are popular for small households. Use the 1/2x preset to instantly cut every amount in half. Doubling and tripling are the most common for entertaining. The 2x and 3x presets handle those with one click. You can also enter any custom serving count, including non-whole numbers, for precise control.
