Scale to GramsHow Much Does an Egg Weigh? Sizes, Grades & Shell Weight
Egg Weight by Official Size
In the United States, eggs are graded by weight per dozen, which translates to consistent per-egg weights. A peewee egg weighs about 35 grams (1.25 oz). A small egg weighs about 43 grams (1.5 oz). A medium egg weighs about 50 grams (1.75 oz). A large egg weighs about 57 grams (2 oz). An extra-large egg weighs about 64 grams (2.25 oz). A jumbo egg weighs about 71 grams (2.5 oz). Most recipes in the US are developed using large eggs. If your recipe does not specify size, assume large.
Shell, White, and Yolk Weights
A large egg breaks down into three components with surprisingly consistent proportions. The shell weighs about 6-7 grams and accounts for roughly 11% of total weight. The white (albumen) weighs about 33-35 grams, making up about 58% of the egg. The yolk weighs about 17-19 grams, or about 31% of total weight. This means when a recipe calls for egg whites from a large egg, you need approximately 33 grams. For just the yolk, approximately 18 grams. Without the shell, a large egg weighs about 50 grams.
Egg Calories and Nutrition by Weight
A large egg (50g without shell) contains about 72 calories. The yolk contains about 55 of those calories (plus most of the nutrients), while the white contains about 17 calories (mostly protein). Per 100 grams, eggs provide 155 calories, 13g of protein, 11g of fat, and virtually zero carbohydrates. Eggs are one of the most nutrient-dense foods available — a single large egg provides 6g of complete protein, 5g of healthy fats, and significant amounts of vitamins B12, D, A, and selenium.
Substituting Egg Sizes in Recipes
When substituting different egg sizes in recipes, weight is a more reliable guide than count. Five large eggs equal approximately four jumbo eggs or six medium eggs by weight. For baking, where precision matters, weigh your eggs: most recipes that call for one large egg need about 50 grams of whole egg (without shell). If you only have medium eggs and a recipe calls for 3 large eggs (150g), use 3 medium eggs plus a little extra white to hit the target weight.
How to Weigh Eggs Without a Scale
If you do not have a kitchen scale, the easiest method is to buy eggs by the labeled size — a carton labeled "large" will contain eggs within the standard weight range. For more precise estimation, you can use the water displacement method: a large egg displaces approximately 50ml of water. You can also use AI-powered tools like Scale to Grams to photograph your eggs and get an instant weight estimate, which is especially useful when working with farm-fresh eggs that are not commercially graded.
