150 × 1.5 2 cups → 3 cups
200 × 2 (double) 2 cups → 4 cups
300 × 3 (triple) 2 cups → 6 cups

How to Use the Recipe Scaler

  1. Copy your recipe: Paste your ingredient list into the text box (one ingredient per line)
  2. Choose scale factor: Enter a percentage (50 = half, 100 = same, 150 = 1.5x, 200 = double) or click a quick button
  3. Click "Convert Recipe": See your scaled measurements instantly
  4. Use the scaled recipe: Copy the converted amounts for cooking or baking

Example: Doubling a Recipe

Original:

  • 2 cups flour
  • 1 cup sugar
  • 3 eggs
  • 0.5 tsp salt

Scale factor: 200 (double)

Result:

  • 4 cups flour
  • 2 cups sugar
  • 6 eggs
  • 1 tsp salt

Common Recipe Scaling Scenarios

Doubling a Recipe (× 2)

To double a recipe, enter 200 as your scale factor. Perfect for meal prep, parties, or making extra to freeze. Remember that doubled recipes may need a larger pan and longer baking time.

Halving a Recipe (× 0.5)

To halve a recipe, enter 50 as your scale factor. Great for cooking for 1-2 people or trying a new recipe without making too much. Halved recipes typically bake faster — check for doneness early.

Scaling from 4 to 6 Servings (× 1.5)

Enter 150 to increase a 4-serving recipe to 6 servings. This is one of the most common conversions for family meals. Original recipe for 4 × 1.5 = 6 servings.

Scaling from 8 to 4 Servings (× 0.5)

Enter 50 to reduce an 8-serving recipe to 4 servings. Useful when cooking for a smaller group.

Tripling a Recipe (× 3)

Enter 300 to triple a recipe. Common for large gatherings or batch cooking. You'll likely need multiple pans and adjusted baking times.

Frequently Asked Questions

How do I double a recipe?

Enter 200 in the scale factor field. This multiplies all ingredient measurements by 2. For example, 1 cup becomes 2 cups, 1/2 teaspoon becomes 1 teaspoon. Remember to adjust baking time and pan size accordingly.

How do I halve (cut in half) a recipe?

Enter 50 in the scale factor field. This divides all measurements by 2. For example, 2 cups becomes 1 cup, 1 teaspoon becomes 0.5 teaspoon (or 1/2 tsp).

What does the scale factor percentage mean?

The scale factor is a percentage of the original recipe size:

Formula: New Amount = Original Amount × (Scale Factor ÷ 100)

Can I scale recipes with fractions?

Yes! The converter works with decimal numbers. You can enter fractions as decimals (1/2 = 0.5, 1/4 = 0.25, 3/4 = 0.75) or type them as you normally would. The tool will process any numbers it finds in your ingredient list.

Does the recipe scaler work for baking?

Yes, the converter works for all recipes including baking. However, baking requires more precision:

What if my recipe has weird decimals like 1.333 cups?

Rounded decimals are normal when scaling. For baking, round to practical measurements:

Or use our cups to grams converter for precise gram measurements.

Can I scale up very large batches?

Yes, but be cautious when scaling beyond 3-4× the original:
