It’s always best to use the pan size called for in a recipe, but sometimes—especially when we are doubling recipes—we need to substitute another pan. Pan capacity may be measured by pouring water into the pan to measure how much it holds, but this chart will make it much easier.
PAN CAPACITY
When choosing a substitute pan for a single-batch recipe, select a pan with the same volume—or capacity—and similar depth.Remember that using a different pan may require an adjustment in baking time. In general, when doubling a baking recipe and placing it in a larger pan, baking time will increase by 20 to 25 percent. For savory recipes, such as lasagna or casseroles, a double batch’s baking time should be increased by about 25 percent. Remember, though, that these increases are estimates only. Continue to trust visual and olfactory cues, as well as relying on baking tests such as the “toothpick test.”
When measuring a pan, measure its width from inside edge to inside edge and its depth from the inside bottom of the pan to the rim.
