About Serving Scaler

Serving Scaler is a free online recipe serving size calculator. It lets you scale any recipe — from a single ingredient to a full dish — to exactly the number of servings you need, without manual arithmetic.

Whether you're halving a weeknight recipe for one, doubling a batch for meal prep, or multiplying a dish to feed a crowd, Serving Scaler handles the conversions and rounds every measurement to a practical kitchen amount.

What it does

• Import from any recipe URL — Paste a link and Serving Scaler extracts the ingredient list and cooking instructions automatically.
• Scale to any serving size — Set the original and target serving counts. Every ingredient updates instantly.
• Kitchen-friendly rounding — Scaled amounts are rounded to common fractions (¼ cup, 1½ tsp) so you can cook without recalculating.
• Paste full recipe text — No URL? Paste the entire recipe and the tool pulls out the ingredient lines.
• Single-ingredient scaler — Scale one measurement at a time using the current serving multiplier.
• Save and share — Create a free account to save converted recipes, share them, or print them.

Why we built it

Scaling a recipe by hand is error-prone and slow, especially when fractions are involved. Serving Scaler was built to remove that friction — you set the serving counts and the tool does everything else, with amounts you can actually measure in a real kitchen.

Free to use

The core calculator is completely free. No account is required to scale or import recipes. An optional account lets you save converted recipes so you can come back to them later.
