Chicken eggs are graded by size, for the purpose of sales.

The egg shell constitutes about 13% of the weight of the egg.

United States of America[edit]

The United States Department of Agriculture sizing is based by weight per dozen.[1] The most common U.S. size of chicken egg is 'Large' and is the egg size commonly referred to for recipes.

The following egg masses including shell have been calculated on the basis of the USDA sizing:
