How to Scale Any Recipe

Paste your ingredient list exactly as you found it – the calculator handles messy formats. Whether the recipe writes “2 cups flour” or “flour, 2 cups” or “200g butter,” it figures out the quantity, unit, and ingredient automatically.

Set your original serving size and desired serving size. The math happens instantly. Use the quick multiplier buttons for common adjustments, or type exact numbers for precision.

Accepted Formats

2 cups all-purpose flour
butter - 250g
Salt, 1/2 tsp
3 large eggs

Common Recipe Scaling Scenarios

½
Halving

Cooking for two instead of four. Recipe makes too much for your household.

2×
Doubling

Dinner party, family gathering, or meal prep for the week ahead.

1½
Odd Numbers

Recipe serves 4, you need 6. Enter those numbers directly.

Quick Unit Reference

The calculator converts between metric and US imperial units automatically. Here’s the reference if you need to verify or do mental math:

Volume (US)MetricNotes
1 teaspoon5 mlStandard measuring spoon
1 tablespoon15 ml3 teaspoons
1 cup237 ml16 tablespoons

Weight (US)MetricNotes
1 ounce28 gSmall amounts of cheese, chocolate
4 ounces113 g1 stick of butter
8 ounces227 g½ pound
1 pound454 g16 ounces

Scaling Baked Goods

Baking is chemistry. Some adjustments beyond simple multiplication may help when scaling significantly:

When Doubling or More

Leavening

Baking powder/soda: scale to 0.9× when doubling. Too much creates metallic taste.

Salt & Spices

Scale to 0.75× to 0.9× for large batches. Flavors concentrate differently.

Bake Time

Larger volumes need longer time at slightly lower temperature. Check doneness early.

Pan Size

Use multiple pans rather than one huge pan for even baking.

Handling Eggs

Eggs don’t divide neatly. When a scaled recipe calls for a partial egg:

1

Large Egg

≈ 50g total
≈ 3 tablespoons

½

Half Egg

Beat egg, measure
1½ tablespoons

⅓

Third Egg

Beat egg, measure
1 tablespoon

For savory dishes, round to the nearest whole egg. For delicate baked goods where precision matters, beat the egg and measure out the portion you need.

Cost Tracking

Enable the cost calculator to see how scaling affects your grocery budget. Enter what each ingredient costs for the original recipe amounts – the calculator multiplies those costs along with the quantities.

This helps with meal planning decisions: sometimes doubling a recipe is more economical than making two separate dishes, and sometimes halving an expensive recipe makes it feasible for a Tuesday dinner.

Example: Scaling Economics

Original (4 servings)

$12.50

$3.13/serving

Doubled (8 servings)

$25.00

$3.13/serving

Halved (2 servings)

$6.25

$3.13/serving

Cooking Fractions

The calculator rounds to practical cooking fractions by default. Nobody measures ⅜ of a teaspoon – it rounds to the nearest fraction you can actually scoop.

⅛

0.125

¼

0.25

⅓

0.333

½

0.5

⅔

0.667

¾

0.75

Turn off “Use cooking fractions” in the options if you need exact decimal values for professional or scientific applications.

Export Options

Three ways to save your scaled recipe:

Copy

Plain text to clipboard. Paste into notes, messages, or any app.

Print

Clean recipe card format. No interface clutter, just the ingredients.

PDF

Download a file to save, email, or add to your recipe collection.
