Recipe scaling calculator
Scaling a recipe should be simple: divide the servings you want by the servings you have, then multiply each ingredient by that factor. Snap a photo of any recipe — a cookbook page, a handwritten card, a screenshot — and the scanner reads it and fills the list in for you, then you pick the new serving count. You can also add the ingredients by hand. The calculator does the arithmetic and formats common results as useful fractions so your shopping list stays readable. For baking, use the result as a starting point and remember that pan size, oven time, and leavening often need their own judgment.

How it works
- 01
The scale factor is new servings divided by original servings.
- 02
Each ingredient amount is multiplied by that factor, while units and ingredient names stay the same.
- 03
Cooking time and pan size do not always scale linearly, especially for baking; use the note as a prompt to check the recipe.
