Recipe Scaler

Scale recipes up or down for any number of servings. Enter ingredients and get instant conversions with easy-to-read measurements.

Recipe Worksheet

Tips:

  • Enter ingredients like "2 cups flour" or "1/2 tsp salt"
  • Fractions (1/2, 3/4) are supported
  • Some ingredients don't scale linearly (e.g., salt, yeast, baking powder)

How to Scale Recipes

Scaling a recipe is simple math: divide the target servings by the original servings, then multiply each ingredient by that number.

Example

A recipe makes 4 servings, but you need 6:

  • Multiplier: 6 ÷ 4 = 1.5
  • If recipe calls for 2 cups flour: 2 × 1.5 = 3 cups
  • If recipe calls for 1 tsp salt: 1 × 1.5 = 1.5 tsp

Ingredients That Don't Scale Linearly

Some ingredients need special attention when scaling:

Scale Conservatively (use ~1.5× when doubling)

  • Salt and spices: Flavors concentrate differently at larger volumes
  • Garlic and onion: Strong flavors can overpower when doubled
  • Leavening agents: Too much baking powder/soda can cause collapse or metallic taste
  • Yeast: Excess yeast creates off-flavors and unstable rise

Scale Exactly

  • Flour and sugar: These are structural and should scale precisely
  • Eggs: Scale precisely (may need to adjust by half eggs)
  • Main proteins: Meat, fish, beans scale directly
  • Liquid base: Stock, milk, water for soups and stews

Tips for Successful Scaling

  • Use weight, not volume: Weighing ingredients (grams) is more accurate than cups
  • Adjust pan size: Larger batches may need bigger pans to maintain proper cooking
  • Watch cooking time: Larger quantities may need more time; smaller may need less
  • Taste as you go: Especially for seasonings, taste and adjust
  • Take notes: Record what worked for future reference

Cooking Time Adjustments

Cooking time does not scale linearly with recipe size. A doubled batch doesn't take twice as long. Guidelines:

  • Stovetop: Doubling may add 25-50% more time if the pan is deeper/fuller
  • Oven baking: Same temperature, but add 10-25% time for doubled batches. Check for doneness early
  • Splitting into two pans: Keeps time similar to original. Rotate pans halfway through
  • Halving a recipe: Reduce time by 25% and check early

Common Measurement Conversions

  • 3 teaspoons = 1 tablespoon
  • 4 tablespoons = 1/4 cup
  • 16 tablespoons = 1 cup
  • 2 cups = 1 pint
  • 4 cups = 1 quart
  • 1 cup flour ≈ 120g
  • 1 cup sugar ≈ 200g
  • 1 cup butter ≈ 227g (2 sticks)

Frequently Asked Questions

How do I scale a recipe up or down?

Divide target servings by original servings to get the multiplier. Multiply each ingredient by this number. Example: 8 servings ÷ 4 servings = 2× multiplier.

Do all ingredients scale equally?

Most do, but some don't. Salt, spices, leavening agents (baking powder/soda), and yeast often need adjustment. When doubling, try 1.5× for these.

Can I scale baking recipes?

Baking is more precise than cooking. Small changes (1.5× or 2×) usually work. Larger changes may need pan size and timing adjustments.

How do I convert between cups and grams?

Conversions vary by ingredient. Flour: 1 cup ≈ 120g. Sugar: 1 cup ≈ 200g. Butter: 1 cup ≈ 227g. For precision, use a kitchen scale.

What about cooking time when scaling?

Cooking time doesn't scale linearly. Larger batches may need slightly longer cooking, but not proportionally. Check for doneness rather than relying on time alone.

How do I halve a recipe that calls for an odd number of eggs?

Beat the full egg until uniform, then measure out half by weight or volume. A large egg weighs about 50g, so half is 25g or roughly 1.5 tablespoons. Use that measured amount in the scaled recipe.

What is the scaling multiplier to go from 12 servings to 9?

Divide target servings by original: 9 divided by 12 equals 0.75. Multiply every ingredient by 0.75. For example, 2 cups of flour becomes 1.5 cups, and 1 tablespoon of oil becomes 3/4 tablespoon.

Why does a 4x batch taste saltier than expected?

Salt and strong spices reach a flavor saturation point at large volumes and do not scale linearly to the palate. For batches larger than 3x, start salt at 2.5x the original amount and season to taste at the end rather than multiplying directly.
