USDA egg size grades

Size Minimum weight per dozen (oz) Weight per egg (oz)
Jumbo 30 2.5
Extra large 27 2.25
Large 24 2.0
Medium 21 1.75

Egg size grading is based on minimum weight per dozen, not on individual egg measurement. A dozen large eggs must weigh at least 24 ounces combined, meaning individual eggs within a carton can vary slightly as long as the total meets the minimum.

Composition

A large egg is composed of roughly 58% white, 31% yolk, and 11% shell by weight. This ratio stays fairly consistent across size grades, so a jumbo egg has proportionally more of both white and yolk than a medium egg, not just a bigger shell.

Quail 1.2 0.35

A duck egg is noticeably larger and heavier than a chicken egg, while a quail egg is much smaller, roughly a fifth the weight of a large chicken egg.
