Adjust recipe servings and calculate nutritional information based on portion sizes
How many servings the recipe/package makes
How many servings you need
A serving size is a standardized amount of food used for nutritional labeling and recipe measurements. When you need to adjust a recipe or understand nutrition for different portions, calculating the correct serving size ensures accurate measurements and nutritional information.
Step 1: Enter the original number of servings your recipe or package contains. For example, if your recipe serves 4 people, enter 4.
Step 2: Enter how many servings you actually need. If you're cooking for 6 people instead of 4, enter 6.
Step 3: (Optional) Enter nutritional information per serving if you want to see adjusted nutrition facts. This is helpful when you're eating more or less than the standard serving size.
The calculator will show you the scaling factor and adjusted nutritional information, making it easy to multiply all your recipe ingredients or understand your actual calorie intake.
Recipe serves 4, but you need 8 servings? The calculator shows you need to multiply all ingredients by 2x. Perfect for dinner parties or meal prep.
Nutrition label shows 2 servings per container, but you ate the whole thing? Calculate actual calories and macros consumed by entering 2 original servings and 1 desired serving.
Planning meals for the week? Scale your favorite recipe from 4 servings to 12 servings for batch cooking. The calculator shows exactly how much to multiply each ingredient.
Ate 1.5 servings instead of 1? Enter the nutritional info per serving and see your actual calorie and macro intake for accurate diet tracking.
Read Labels Carefully: Nutrition labels show information "per serving," but packages often contain multiple servings. Check "servings per container" to understand total nutrition.
Use Measuring Tools: For accurate serving sizes, use measuring cups, spoons, and a kitchen scale. Eyeballing portions often leads to underestimating serving sizes.
Standard Serving Sizes: USDA standard servings are often smaller than typical portions. For example, a serving of pasta is 2 oz dry (about 1 cup cooked), but restaurants often serve 3-4 servings.
Recipe Scaling Limits: While this calculator handles the math, some recipes don't scale perfectly. Baking recipes especially may need adjustments to baking time and temperature when significantly scaled up or down.
The FDA requires nutrition labels to use standardized serving sizes based on Reference Amounts Customarily Consumed (RACC). However, these serving sizes may differ from what you actually eat:
Understanding the difference between serving size and portion size is crucial for nutrition tracking:
Serving Size: A standardized amount defined by the FDA for nutrition labeling. It's based on what people typically eat, but it's not a recommendation for how much you should eat.
Portion Size: The actual amount of food you choose to eat at one time. Your portion might be larger or smaller than the standard serving size.
Why It Matters: If you eat a portion that's twice the serving size, you're consuming double the calories and nutrients listed on the label. Use this calculator to accurately track your intake.
