Tin converter

Convert the tin a recipe asks for to one you actually own, with scaling if required.

Notes & precision

  • How much to make. Making this much of the recipe keeps the batter at the same depth in your tin, so it bakes and browns just like the original.
  • Same tin, two labels. A 20 cm and an 8″ tin are the same tin sold in different units. Use the nearest, or pick the size you actually own.
  • Check it early. A wider or shallower tin bakes faster, so start testing for doneness before the recipe's time is up.
