Copy the adjusted recipe to your clipboard or make further adjustments to the serving count.

About This Tool

Adjusting a recipe for more or fewer people is one of the most common kitchen challenges. Simply doubling or halving ingredients sounds easy, but fractions get awkward fast - what is two-thirds of three-quarters of a cup? Our Recipe Scaler takes the guesswork out by letting you enter your original recipe, specify the new serving count, and instantly see every ingredient scaled with smart fraction rounding that produces practical, measurable amounts.

The scaler handles whole numbers, decimals, fractions, and mixed numbers in your ingredient list. When scaling produces odd amounts like 0.333 cups, it rounds intelligently to the nearest practical measurement - in this case, one-third cup. It understands common cooking fractions and always rounds to amounts you can actually measure with standard kitchen tools like quarter, third, and half increments.

This tool is perfect for meal prepping larger batches, cooking for a dinner party, or cutting a family-sized recipe down to a single serving. Enter your ingredients line by line with quantities, scale to your desired servings, and copy the adjusted recipe. It saves time and eliminates the mental math that leads to kitchen mistakes.

Frequently Asked Questions

Yes. You can scale from any original serving count to any target. The calculator works with whole numbers and fractions. Scaling from 4 servings to 7, from 12 to 3, or from 6 to 1 all work perfectly. Very large scaling factors (like 10x) may require adjustments to cooking times and equipment.
Cooking times often need adjustment when scaling. Larger batches may take longer, especially for baked goods where heat needs to penetrate a bigger volume. Doubling a recipe usually adds 25-50% more cooking time, not double. Use a thermometer to check doneness rather than relying solely on time.
Smart fraction rounding converts awkward amounts into practical measurements. Instead of showing 0.167 cups, the scaler rounds to the nearest standard fraction you can measure - like one-sixth cup or 2 tablespoons plus 2 teaspoons. It prioritizes fractions common in cooking: halves, thirds, quarters, and eighths.
Seasonings like salt, spices, and garlic often scale at about 75% of the factor for other ingredients. If you double a recipe, start with 1.5 times the seasoning and adjust to taste. Strong flavors like cayenne pepper, vinegar, and vanilla extract are especially important to scale conservatively.
Enter each ingredient on its own line with the amount first, followed by the unit and ingredient name. For example: "2 cups flour" or "1/2 tsp salt" or "3 large eggs." The scaler recognizes common formats including fractions, decimals, and mixed numbers like "1 1/2 cups sugar."
