Recipe Scaler
Resize an ingredient list up or down by servings.
Scale any recipe cleanly
Doubling a recipe or cutting it down for two means recalculating every quantity, and the fractions make it error-prone. This scaler multiplies each ingredient by the serving ratio for you.
Enter the original and desired servings, paste the ingredient lines, and it rewrites each quantity. It handles whole numbers, decimals, fractions like 1/2, and mixed numbers like 1 1/2, leaving the rest of the line untouched.
Accurate and private
The scaling runs in your browser, so your recipe is never uploaded.
