How many grams is 1 egg? A complete guide to egg weights

November 24, 2025 •

3 min read

Globally, egg sizing standards vary, which can lead to confusion when converting recipes, and a single large egg can be anywhere from 50 to 57 grams depending on the region. Understanding how many grams is 1 egg based on its size is crucial for precise cooking and baking, where exact measurements impact the final dish.

Quick Summary

The weight of a single egg varies significantly by size and region. Standardized weight ranges exist for different grades like small, medium, large, and jumbo. Factors like hen's age and nutrition influence egg size. For accurate results in baking, it is recommended to weigh the eggs or use equivalent quantities, especially when multiple eggs are required.

Key Points

Weight Varies by Size: A standard 'large' egg weighs about 57 grams, but sizes range significantly from small (around 43g) to jumbo (71g+).
Size Matters for Baking: For precise baking, using the correct egg size or weighing the equivalent amount is crucial, as liquid ratios can greatly affect the final texture.
Egg Components Differ: The egg white makes up most of the weight, while the yolk is the most nutrient-dense part, and both vary in proportion with egg size.
Multiple Factors Influence Weight: The weight of an egg is affected by the hen's age and breed, nutrition, and environmental factors like temperature.
Weigh for Precision: A digital kitchen scale is the best tool for accurately measuring the weight of whisked eggs when a recipe calls for an exact amount or a fraction of an egg.
Nutritional Value Varies: While the nutritional profile per gram is similar, the total calorie and protein content of an egg increases with its size.
Substitutions are Possible: You can substitute different size eggs in recipes by using a conversion chart or by weighing the eggs to match the total required weight.

Egg Weight by Size: A Comprehensive Breakdown

The weight of an egg is not a one-size-fits-all answer. Egg sizes are officially categorized by weight, not just appearance, and can differ slightly depending on the country. Most recipes are developed using 'large' eggs, making it essential for home cooks and bakers to know the different weight categories to ensure consistent results. For example, in the US, a large egg averages around 57 grams, while a large egg in some European standards can be over 63 grams.

The Anatomy of an Egg and Its Weight

An egg's total weight is composed of three main parts: the shell, the white (albumen), and the yolk.

The Shell: This accounts for approximately 10% of the total egg weight. Its thickness and strength can be influenced by the hen's nutrition.
The Egg White (Albumen): The largest component, making up about 60% of the egg's liquid weight. The amount of white increases as the hen ages.
The Yolk: This is the most nutrient-dense part, accounting for about 30% of the weight. The size of the yolk increases with the age of the hen, impacting the overall egg weight.

Weight Variations by Egg Size

The weight difference between egg sizes becomes more significant when using multiple eggs in a recipe. While swapping a single egg might not affect a dish much, substituting multiple eggs without adjusting the quantity or weight can significantly alter the outcome, especially in delicate baked goods like cakes and custards. For instance, a recipe calling for four large eggs would require a different number of jumbo or medium eggs to maintain the correct liquid ratio.

How to Measure Eggs Accurately

For those who prefer precision or are adapting a recipe, measuring eggs by weight is the most reliable method. This is particularly useful for baking, which is a more exact science than general cooking.

Steps for accurate egg measurement:

Use a digital kitchen scale: A digital scale is the most accurate tool for measuring ingredients by weight.
Crack eggs into a separate bowl: This allows you to whisk them together before measuring the required amount in grams. For example, if a recipe calls for 100 grams of whole egg, you can easily measure out the correct quantity from the whisked mixture.
Use for partial eggs: This method is also ideal for recipes that require half an egg. Simply whisk a whole egg and use half its weight.

Comparison Table: Standard Egg Weights (US)


Egg Size	Approx. Weight (grams, in shell)	Approx. Weight (ounces, in shell)	Equivalent Volume (without shell)
Small	43 g	1.5 oz	approx. 3 tbsp
Medium	50 g	1.75 oz	approx. 3.5 tbsp
Large	57 g	2.0 oz	approx. 4 tbsp
Extra-Large	64 g	2.25 oz	approx. 4.5 tbsp
Jumbo	71 g	2.5 oz	approx. 5 tbsp

Factors That Influence Egg Weight

Beyond the standardized sizing, several factors can cause slight variations in egg weight.

Hen's Age: Younger hens tend to lay smaller eggs, while older, more mature hens produce larger ones.
Breed of Hen: The breed of the hen has a direct impact on the size of the eggs it produces.
Diet and Nutrition: The hen's feed intake and diet, especially levels of protein and linoleic acid, can affect egg size.
Environmental Temperature: High temperatures can cause hens to eat less, resulting in smaller eggs.
Genetics: Egg weight is a heritable trait, and some breeds are genetically predisposed to lay larger eggs.

Conclusion

While a large egg is often the default assumption, understanding that a single egg's weight can vary significantly based on its size category is essential for achieving reliable cooking and baking outcomes. Standardized grading systems exist, but for maximum precision, especially in baking, weighing eggs is the most accurate method. Awareness of the components that contribute to an egg's weight and the factors that influence it empowers home cooks to make informed choices for their recipes and nutritional goals.

Frequently Asked Questions

In the United States, a large egg averages around 57 grams, including the shell. This is the standard size used in most recipes, especially for baking.

In most U.S. standards, a medium egg averages around 50 grams. However, some international standards may classify a medium egg as 53-63g.

An extra-large egg typically weighs about 64 grams. This is a good choice for recipes where a bit more egg is desired, such as in omelets or frittatas.

In baking, precision is key. The weight of eggs significantly affects the liquid-to-dry ingredient ratio, which can impact the texture, rise, and moisture of the final product.

In a large egg, the egg white typically weighs about 30-34 grams, while the yolk weighs approximately 18-20 grams. The shell accounts for the rest of the total weight.

Yes, egg weight classifications can vary by country. For example, a 'large' egg in the US has a different weight standard than a 'large' egg in the UK or Australia, so always consider the source of your recipe.

For recipes with one or two eggs, substitution is usually fine. For recipes requiring more eggs, it's best to use a conversion chart or weigh the eggs to ensure the total gram weight matches the original recipe's requirement.
