Size tells you the minimum required net weight per dozen eggs. It does not refer to the dimensions of an egg or how big it looks. While some eggs in the carton may look slightly larger or smaller than the rest, it is the total weight of the dozen eggs that matters. Eggland's Best strictly follows the USDA-specified minimum net weight per dozen eggs for the grades marketed under the Eggland's Best Brand. For example: A dozen Large eggs must have a total minimum weight of 24 ounces.
