Egg Size Conversion Calculator

How this works

USDA egg size grades are defined by minimum weight per dozen, not by shell dimensions, so a jumbo egg is meaningfully bigger than a small egg. This calculator converts your recipe's total egg weight from one size to another and reports the equivalent count, since baking recipes are sensitive to total liquid volume from eggs.

Source: Egg size weights follow USDA egg grading standards for weight per dozen (e.g., large eggs average 2 oz / 56.7g each in the shell).
