How to Convert Loaf Pan Sizes

Use your existing range of loaf pans to bake bread and cakes of any size and from any recipe. Knowing how to substitute pans of different sizes gives you greater flexibility to experiment with new and exciting recipes, even if they are written for specialized baking pans. Substitute round for square or rectangular pans by using a straightforward conversion chart and a measuring jug.

Things You'll Need

  • Pan conversion chart
  • Measuring jug

Instructions

  1. Check the recipe for the dimensions of the recommended pan.

  2. Locate and print a baking pan conversion chart. Charts are available online from websites such as Old Farmer's Almanac, Cookaz or Joy of Baking. Use the conversion chart to find the recommended pan details.

  3. Check the pan substitutions that can be used. Also check for the volume equivalent.

    For example: A 9-inch by 5-inch by 3-inch loaf tin has a volume of eight cups. Suitable substitutions may be an 8-inch square pan or a 9-inch round pan.

    An 8- inch round pan that is 2 inches deep can be substituted with a 9-inch square pan of the same depth.

  4. Measure the volume of the pan you wish to use, if you do not already know the capacity and it is not listed on the table. Measure the volume by filling it with water from a measuring jug.

  5. Compare your pan capacity with the suggested pan from your recipe. Your pan should be at least as large as the one required by the recipe. If it is not, scale down or up the quantities of ingredients as necessary.

    For example, if your pan size is three cups but the recipe requires a four-cup size, you should use 3/4 of the quantities listed.

    If the recipe makes four cups of mixture but your desired pan is eight-cup capacity, then multiply the ingredient quantities by two.
