It is not always possible to have the exact size pan called for in a given recipe. Additionally, bakeware manufacturers seem to produce endless different dimensions, such as 87/64” instead of 8”. All sizes below are rounded to nearest 1/2” and 1/2 c. These conversions may be helpful when modifying a recipe to fit a particular pan. Plan on about 1/4 c error rate depending on actual pan size. Baking times may also change with pan configuration.
