Chicken eggs are graded by size, for the purpose of sales. The egg shell constitutes 8–9% of the weight of the egg (calculated from data in Table 2, F. H. Harms)[1]

United States of America[edit]

The United States Department of Agriculture sizing is based by weight per dozen.[2] 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:

Modern Sizes (US)
Size Minimum mass per egg Cooking Yield (Volume)[3]
Jumbo 70.9 g 2.5 oz.
Very Large or Extra-Large (XL) 63.8 g 2.25 oz. 56 ml (4 tbsp)
Large (L) 56.7 g 2 oz. 46 ml (3.25 tbsp)
Medium (M) 49.6 g 1.75 oz. 43 ml (3 tbsp)
Small (S) 42.5 g 1.5 oz.
Peewee 35.4 g 1.25 oz.

Canada[edit]

In Canada, modern egg sizes are defined as follows:

Modern Sizes (Canada)[4]
Size Minimum mass per egg
Jumbo 70 g
Extra Large 63 g
Large 56 g
Medium 49 g
Small 42 g
Peewee Less than 42 g

European Union[edit]

In Europe, modern egg sizes are defined as follows.[5]

Size Minimum mass per egg
Extra large (XL) 73 g
Large (L) 63 g
Medium (M) 53 g
Small (S) Less than 53 g

Post-Soviet countries[edit]

In countries which are members of Interstate Council for Standardization, Metrology and Certification: Russia, Belarus, Moldova, Kazakhstan, Azerbaijan, Armenia, Kyrgyzstan, Uzbekistan, Tajikistan, Georgia, and Turkmenistan eggs are sorted into five categories by mass:[6]

Category Mass range per egg
Highest (В) 75 g and more
Select (О) 65 g – 74.9 g
First (1) 55 g – 64.9 g
Second (2) 45 g – 54.9 g
Third (3) 35 g – 44.9 g

Australia[edit]

In Australia, the Australian Egg Corporation defines the following sizes in its labeling guide.[7]

Modern Sizes (Australia)
Size Mass range per egg Average mass per egg
King‐size 71.7 g – 78.5 g 73 g
Jumbo 66.7 g – 71.6 g 68 g
Extra-Large 58.3 g – 66.6 g 60 g
Large 50.0 g – 58.2 g 52 g
Medium 41.7 g – 49.9 g 43 g

In Western Australia, two additional sizes are also standardized by the Golden Eggs Corporation[8]

Additional Sizes (Western Australia)
Mega or XXXL 72 g
Medium 43 g
