Scaling Tips

What Scales Linearly

  • • Most liquids and dry ingredients
  • • Proteins (meat, beans, eggs)
  • • Vegetables and fruits
  • • Pasta, rice, and grains

What Doesn't Scale Perfectly

  • • Leavening agents (use 75-80% when doubling)
  • • Salt and spices (adjust to taste)
  • • Cooking times (may vary)
  • • Pan sizes (may need multiple pans)

How to Scale a Recipe

Whether you're cooking for a crowd or just making dinner for two, our recipe scaler helps you adjust ingredient quantities automatically. Simply enter your original recipe's serving size, the number of servings you want, and we'll calculate the new amounts.

When to Use a Recipe Scaler

  • Dinner parties: Double or triple your favorite recipes for guests
  • Cooking for two: Halve recipes designed for families
  • Meal prep: Scale up recipes for the whole week
  • Portion control: Adjust recipes to meet dietary needs

Tips for Successful Scaling

While most ingredients scale linearly, some require special attention. Baking recipes with leavening agents like baking powder or yeast often need adjustments—when doubling, use about 75-80% of the calculated amount. Spices and salt should be added gradually and tasted, as doubling them can overwhelm a dish.
