How to use this tool
Scale line-by-line ingredient quantities from original to target servings and export the list.
Easily scale recipe ingredients up or down for any crowd size. Whether cutting a 4-person dinner recipe down for 2 or multiplying a holiday party punch for 15, get mathematically precise measurements without culinary guesswork.
💡 3 Quick Steps to Get Started
Enter original recipe yield (e.g. 4 servings) and your target yield (e.g. 10 servings).
List your recipe ingredients with their original numbers and units (cups, grams, spoons).
Instantly view perfectly proportioned amounts tailored for your batch size.
When it helps
Adjust home recipes, party batches, and meal-prep quantities.
How it works
Multiplier = target servings ÷ original servings; each line quantity is multiplied and rounded to two decimals.
Worked example
Example: 200 g flour for 4 servings becomes 500 g for 10 servings.
Limits and data handling
Out-of-range servings, rows without exactly three fields, blank fields, or invalid quantities produce no result. Seasoning, cooking time, and cookware capacity may not scale linearly and still need judgment.
Servings, ingredient rows, scaled results, and the CSV are processed or generated only in your current browser. Recipe content is not sent to the GoGo Tools backend.
Recipe Scaling, Baker's Percentage & Culinary Ratios Guide
1. Culinary Scaling Factor Arithmetic
Scaling recipes across varying serving sizes relies on calculating the Scaling Factor: Target Yield ÷ Original Yield. Multiplying each ingredient by this coefficient guarantees proportional balance.
In culinary scaling, aromatic seasonings (salt, spices, alcohol, leavening agents) should often scale non-linearly (using a 0.8x to 0.9x damping multiplier on large batch expansions) to account for surface-area evaporation kinetics.
2. The Baker's Percentage System Explained
Professional pastry chefs utilize Baker's Percentages, where total flour weight is permanently indexed as 100%. All secondary ingredients (water, salt, yeast, fats) are expressed relative to total flour mass (e.g., 70% hydration dough). This system facilitates dynamic batch sizing while maintaining structural crumb integrity.
3. Mass vs. Volume: Density Dynamics in Baking
Precision baking mandates kitchen scales measuring in grams rather than volumetric measuring cups. Dry powders vary wildly in bulk density depending on settling (1 cup of un-sifted flour spans 120g to 150g), directly impacting gluten development.
4. Thermal Adjustments: Baking Time and Temperature
Scaling pan geometries changes heat penetration rates. Converting large loaf pans to ramekins requires decreasing bake times while adjusting oven temperature to prevent crust scorch.

FAQ
Recipe scaler: How should I format the ingredient list?
Original and target servings must be from 1 to 100,000. Each nonblank line must contain ingredient,quantity,unit with a quantity of zero or more. The limit is 1,000 lines and 500 characters per line.
Recipe scaler: How is each ingredient quantity scaled?
The multiplier is target servings divided by original servings. Each original quantity is multiplied and rounded to two decimals; the screen shows scaled amounts, and the CSV keeps both original and scaled quantities.
Recipe scaler: Which errors or practical limits should I consider?
Out-of-range servings, rows without exactly three fields, blank fields, or invalid quantities produce no result. Seasoning, cooking time, and cookware capacity may not scale linearly and still need judgment.
Recipe scaler: Is my recipe sent to a server?
Servings, ingredient rows, scaled results, and the CSV are processed or generated only in your current browser. Recipe content is not sent to the GoGo Tools backend.
