Handy Chicken Egg Size Chart

What does it mean when a recipe calls for a medium egg? How do your fresh backyard eggs measure up?

If you do any baking, I'm sure you've seen recipes that call for "three medium eggs" or "two large eggs". But what does that mean? And how do your fresh eggs from your chickens measure up?

Well, I'll show you how to tell.

Did you know that commercially sold eggs are weighed by the dozen, not by the individual egg?

So while there can be some variance from egg to egg within a carton, as long as the aggregate weight of the entire carton is consistent with the weight for that egg size, that's what will be printed on the carton label.

While an individual egg in a carton can vary a bit, these are the average weights for eggs in each size class as well as the total weight of a carton of each size egg.


Egg carton weighing 18 ounces or an average of 1.5 ounces per egg


Egg carton weighing 21 ounces or an average of 1.75 ounces per egg


Egg carton weighing 24 ounces or an average of 2.0 ounces per egg


Egg carton weighing 27 ounces or an average of 2.25 ounces per egg


Egg carton weighing 30 ounces or an average of 2.50 ounces per egg

So how can you figure out what size your chickens' eggs are?

The easiest way is to use a postage scale or food scale to weigh them. One you have the weight of each egg in ounces, put it in the proper carton and label the cartons.

Then double check at the end to be sure each carton weighs in at the proper weight. But just so you know, most small scale sellers at farmers markets or at a roadside stand aren't required to size (or grade) the eggs they sell.

And check your state Egg Laws, but likely you aren't required to package your eggs by size - even though its kind of fun to weight your eggs just to see where they stand.

Especially if you collect a double yolker, which can weigh in over 4 ounces!

Fun fact: A medium egg measures out to about 3 Tablespoons (one Tablespoon of yolk, two Tablespoons of white)

One final comment.

Even though a recipe may call for a Medium egg or a Large egg, I have never worried about the actual weight of one of our chicken eggs.

And I've often subbed in duck eggs which are about 30% larger than a chicken egg - even recipes when I'm baking - and never had any problems.

Since there's such a slight difference in size in the chicken eggs, I don't think it much matters honestly whether you use a medium, large or even jumbo egg in most recipes.
