Should You Measure Flour by Weight or Volume?

Most experts agree that dry ingredients like flour should be measured by weight rather than volume, especially in baking. The reason for this is that flours vary slightly in density, so a volume measurement will likely yield an incorrect amount of ingredients. Additionally, the amount that the flour is packed or compressed in the cup or tablespoon will alter the amount of ingredients being added.

For these reasons, a food scale, rather than measuring cups or spoons, is the preferred way to measure flour when cooking. For recipes that call for measurements in volume, professional bakers use a whisk to aerate flour that's been stored in a bag or canister before measuring since flour will settle when stored and weigh heavier even in the same-sized measuring cup.

Pounds and cups are both units used to measure flour. Keep reading to learn more about each unit of measure.
