How Many Grams Does a US Large Egg Weigh
A large egg in the United States weighs between 56 and 63 grams with the shell, according to the USDA standard. If you’ve just moved and are trying to follow an American recipe with your kitchen scale in grams, this fact will save you confusion and wasted eggs.
The exact weight of a large egg according to the USDA
The United States Department of Agriculture (USDA) classifies eggs by minimum weight per dozen, not by individual egg, but from that the average weight per unit is derived. A large egg weighs approximately 57 grams with the shell. Without the shell, the edible part (white plus yolk) is around 50 grams.
This fact is key because many American recipes simply say “1 large egg” without specifying grams, assuming everyone cooks with the same standard.
Egg size categories in the US and their weights
At the American supermarket you’ll find several size categories, each with a minimum weight per dozen set by the USDA:
- Peewee: 15 oz per dozen (~35 g per egg)
- Small: 18 oz per dozen (~43 g per egg)
- Medium: 21 oz per dozen (~50 g per egg)
- Large: 24 oz per dozen (~57 g per egg)
- Extra Large: 27 oz per dozen (~64 g per egg)
- Jumbo: 30 oz per dozen (~71 g per egg)
The large egg is, by far, the standard in supermarket cartons and the one assumed by all baking and savory cooking recipes in the US.
Grams of a large egg: white, yolk and shell separately
If you need precision for a baking recipe, here’s the approximate breakdown of a 57-gram American large egg:
- Shell: 6-7 grams
- White (albumen): 30-33 grams
- Yolk: 17-19 grams
This distinction matters a lot in precision baking recipes, where accurately separating white and yolk changes the final result of the batter or meringue.
US large egg weight vs. medium egg in other countries
If you come from a country where “medium” or “large” eggs have a different weight reference, watch out: the American large egg doesn’t always match the “large” category you used before. In many classification systems outside the US, a “medium” egg can weigh between 53 and 63 grams, very close to the American large.
Practical recommendation: when an American recipe says “large egg”, use 57 grams as a reference and adjust slightly if your local egg weighs differently.
Why American recipes always use large egg
Almost all US baking and cooking is calibrated with the large egg as the base unit. Cookbooks, blogs and TV shows assume that size by default. If you use an extra large or medium egg without adjusting, you alter the proportion of liquids in the recipe, which can affect the texture of cakes, breads and sauces.
When a recipe calls for several eggs, that margin of error multiplies. That’s why it’s a good idea to weigh the eggs if you’re unsure, instead of relying solely on the carton label.
How to convert grams of egg to ounces for labels and recipes
Many product labels and some older American recipes still use ounces instead of grams. A 57-gram large egg equals approximately 2 ounces. If you need to make this conversion quickly and accurately for any ingredient, not just eggs, you can use the grams to ounces calculator and avoid manual calculations that often lead to rounding errors.
How to weigh your own eggs to adjust recipes
If you have a kitchen scale, the most reliable method is this:
- Weigh the whole egg with the shell.
- If it’s between 56 and 63 grams, it counts as a standard large egg.
- If it weighs less than 50 grams, it’s medium; adjust the recipe using a smaller fraction or add a bit of extra liquid.
- If it weighs more than 64 grams, it’s extra large; consider slightly reducing other liquids in the recipe.
This adjustment is especially relevant in baking, where the exact ratio between egg, flour and sugar determines the final texture. If you also need to check how many grams of flour or sugar correspond to each cup in your recipe, this article on how many grams of flour are in a cup can help.
Common mistakes when converting American eggs to grams
The most common mistake is assuming that “large” in English means the same as “large” in your home country, without checking the actual weight. Another typical mistake is not differentiating between the weight with shell and without shell when following recipes that specify grams of beaten egg or egg white alone.
If your recipe comes from an American baking blog and mentions grams for other ingredients in cups, also check how that step-by-step conversion of an American recipe from cups to grams is done to avoid surprises in the final result.
Frequently asked questions
How many grams does a large egg have in the United States?
A large egg weighs approximately 57 grams with the shell, according to the USDA standard, which defines this category with a minimum weight of 24 ounces per dozen.
How much does a large egg weigh without the shell?
Without the shell, a large egg weighs around 50 grams, split between 30-33 grams of white and 17-19 grams of yolk.
Is an American large egg the same as a large egg in my country?
Not necessarily. The American large egg weighs 57 grams, while in other classification systems a “medium” egg can be around that same weight. It’s a good idea to check the actual weight on the carton label, not just the category name.
Why do American recipes always call for a large egg?
Because it’s the most common standard size in US supermarkets, and all liquid ratios in baking and savory cooking recipes are calibrated assuming that weight of 57 grams per egg.
How do I convert grams of egg to ounces?
A 57-gram large egg equals approximately 2 ounces. For more precise conversions with other weights, you can use a grams to ounces calculator instead of doing the math manually.
