Recipe Scaler
Paste an ingredient list, tell it how many servings you want, and get the whole list rescaled — fractions like 1½ cups and 3/4 tsp included.

How it works
The scaling factor is desired servings ÷ original servings (or whatever you type in the factor box — the factor box wins if you fill it). Each line's leading quantity is multiplied by that factor. Quantities close to a kitchen-friendly fraction are shown as fractions (2¼ instead of 2.25); everything else is rounded to two decimals. Lines without a leading number (like "pinch of salt") are left untouched for you to judge.
FAQ
Do baking times change when I scale a recipe?
Usually, but not proportionally. Bigger volume in a deeper pan bakes longer at the same temperature; wider and shallower bakes faster. Start checking at the original time.
Which ingredients don't scale linearly?
Leaveners, salt, and strong spices. For 0.5×–2× the straight multiple is fine. Beyond ~3×, cut leavening by 10–15% and season to taste.
Can I scale by weight instead of cups?
Yes — weights scale perfectly and are more accurate. Convert cups to grams first with our cups to grams converter, then scale.
