How to Scale a Recipe Correctly

Scaling a recipe—adjusting the ingredient quantities to make a larger or smaller batch—is a common kitchen task. Our Recipe Scaler makes the math easy, but understanding the principles will help you achieve perfect results every time.

1. Find Your Scaling Factor

The first step is to determine your scaling factor. This is done by dividing the desired number of servings by the original number of servings. For example, if a recipe serves 4 people and you want to make it for 6, your scaling factor is 6 / 4 = 1.5. To halve a recipe, the factor is 0.5. To double it, the factor is 2.

2. Multiply Your Ingredients

Once you have your scaling factor, multiply the quantity of each ingredient by this number. Our calculator automates this for you. Just enter your original ingredients and the scaling factor, and we'll provide the new measurements.

Tips for Successful Scaling

• By Weight is Best: If possible, use weights (like grams) instead of volumes (like cups) for dry ingredients, as it's much more accurate.
• Be Careful with Spices: Spices and seasonings might not scale linearly. It's often best to start with a slightly smaller amount than calculated, then taste and adjust.
• Adjust Cooking Time: A larger batch may require a longer cooking time, while a smaller batch may cook faster. Keep an eye on your dish.
• Consider Pan Size: When scaling up or down, you may need to use a different sized pan to ensure even cooking.

Our Recipe Scaler is the perfect tool for quickly adjusting any recipe, taking the guesswork out of your kitchen conversions.
