Pan Size Converter

Recipes are written for a specific pan. Here's how to find an equivalent by surface area, and how to adjust your bake time when you switch.

General bake-time adjustment rule

If your pan has less surface area than the recipe calls for, the batter will be deeper — bake longer at a slightly lower temperature (drop 25°F) to cook through without burning the top. If your pan has more surface area, the batter will be shallower — bake for less time and check 10-15 minutes early.
