Convert a baking recipe to the pan you actually own.

Tell us which pan the recipe expects and which pan is in your cupboard. Savor works out the batter multiplier, shows how the depth changes and can scale the ingredient list for you.

Pan dimensions

Area-based scaling works best when the pans are a similar depth.

Batter depth: Without scaling, the batter would sit about 21% shallower in the new pan.

Bake time: A shallower layer can bake faster. Start checking before the original recipe time rather than trying to calculate a new bake time.

Scale the ingredients for the new pan.

Original ingredients

Quantities are multiplied by the pan-area ratio. Lines without a leading quantity stay as written.

For your pan

1.27×
1.9 cups flour
15/16 cup sugar
2.53 eggs
5/8 cup butter
1 1/4 tsp baking powder

The useful caveat

Pan area can scale batter. It cannot promise a bake time.

Scaling by surface area keeps batter depth roughly similar when the pans have comparable depth and shape. That makes it a good starting point for cakes, brownies and tray bakes — but ovens, pan material, batter type and actual pan depth still matter.

  • Fractional egg? Beat the egg first, then use the fraction by weight or volume rather than trying to split yolk and white by eye.
  • For baking, keep an eye on pan area and batter depth. Ingredient maths can scale perfectly while the bake still behaves differently.
  • Cooking time does not scale with the multiplier. Use the original time as a first checkpoint, then cook to colour, texture or temperature.
How it works

Same depth = target area ÷ original area.

An 8-inch round pan has about 50.3 square inches of surface area. A 9-inch round has about 63.6. Divide 63.6 by 50.3 and you get roughly 1.27 — so making 1.27× the batter keeps the depth close to the original recipe.

This is intentionally an area calculator, not a fake-precision oven predictor. Deep tins, very shallow trays, Bundt pans and unusually sloped pans are better compared by actual capacity.

new pan area÷recipe pan area=recipe multiplier
Keep the recipe, not the maths
