Recipe Scaler

Scaling a recipe up for a dinner party or down for a quiet night in? Enter your original and desired servings, paste in the ingredient list, and every quantity is recalculated instantly — free, private, and with no sign-up.

How to Use

  1. Enter the number of servings the original recipe makes and the number of servings you want.
  2. Paste your ingredient list into the box, one ingredient per line, starting each line with the quantity.
  3. Click “Scale Recipe” — every quantity is multiplied by the scaling factor and shown below.
  4. Copy the scaled list with one click and use it in the kitchen.

Key Features

  • Smart quantity parsing — understands whole numbers, decimals and fractions such as 1/2 or 1 1/2.
  • Kitchen-friendly fractions — scaled amounts are shown as handy fractions like 1/4, 1/3 or 3/4 where they fit.
  • Scale up or down — works for doubling a batch or shrinking it to a single portion.
  • Lines without quantities pass through — notes like “salt to taste” are left untouched.
  • 100% private — everything is calculated in your browser and never sent to a server.

FAQs

Is this recipe scaler free to use?

Yes. The scaler is completely free with no sign-up, no usage limits and no hidden charges.

How are fractions handled?

The tool recognises fractions such as 1/2 and mixed numbers such as 1 1/2. Scaled results are converted back to the nearest common kitchen fraction where possible, so you get “1/2 cup” rather than “0.5 cup”.

What happens to lines without a quantity?

They are copied through unchanged. This is handy for lines like “salt to taste” or “fresh herbs to garnish”, which should not be scaled.

Is my recipe uploaded anywhere?

No. All scaling happens locally in your browser using JavaScript, so your recipe never leaves your device.
