Enter how many eggs of one size your recipe calls for to see the equivalent count in a different egg size.
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).
For most everyday cooking it's minor, but in precise baking (like delicate cakes, meringues, or soufflés) using a very different egg size than the recipe assumes can noticeably change moisture and structure.
Unless stated otherwise, most U.S. recipes are written and tested using large eggs, which average about 2 ounces (56.7g) each in the shell.
About 2.7 small eggs, since large eggs average roughly 56.7g each and small eggs average about 42.5g each.
