The Importance of Precise Egg Weight in Baking
When following a recipe, particularly for delicate pastries, cakes, and other baked goods, consistency is paramount. Relying on a 'large egg' can introduce significant variability, as the weight of eggs labeled 'large' can fluctuate.
For instance, while the USDA defines a large egg as weighing approximately 57 grams, another source suggests a range from 54.34 to 61.41 grams. This difference of several grams per egg can add up quickly, especially in recipes calling for multiple eggs. Two eggs at the lower end of the range would be about 108.68 grams, while two at the higher end would be 122.82 grams. That 14-gram difference could alter the moisture balance and structure of your final product. This is why many professional bakers and modern recipes specify ingredients by weight, not volume or quantity.
Large Egg Weight by Region
Egg grading standards vary by country. The weight of a "large" egg is not universal, which further emphasizes the need for a kitchen scale. This table illustrates how the weight of a standard egg size can differ around the world.
| Region | Standard Large Egg Weight | Two Large Eggs (Approximate) |
|---|---|---|
| United States (USDA) | ~57g (2 oz) | ~114g |
| Canada (Grade A Large) | Minimum 56g | Minimum 112g |
| European Union (L) | 63-73g | 126-146g |
| Australia (59g egg) | ~52g (596g/dozen) | ~104g |
Factors That Influence an Egg's Weight
Several factors contribute to the weight variation of eggs, even within the same size classification. These factors range from genetics to environmental conditions.
- Hen's Age: Younger hens tend to lay smaller eggs, while eggs get progressively larger as the hen ages, reaching maximum size around one year old.
- Hen's Breed: Different chicken breeds are genetically predisposed to lay eggs of varying sizes. Some breeds, like Leghorns, lay smaller eggs, while others, like Orpingtons, lay much larger eggs.
- Nutrition: The hen's diet significantly affects egg size. Diets rich in specific amino acids and fat, like linoleic acid, can increase egg size. Poor nutrition can result in smaller eggs.
- Environment: High ambient temperatures can cause hens to eat less, leading to smaller eggs. Stress, lighting programs, and flock density also play a role in egg weight variation.
- Shell Weight: While a relatively small percentage of the total weight (around 7-8g for a large egg), variations in shell thickness and density contribute to the overall weight.
Why Weighing Your Eggs Is a Best Practice
For home bakers who want to achieve professional and consistent results, using a digital kitchen scale is a game-changer. By measuring eggs by weight, you eliminate the guesswork associated with variations in size. Here's how to do it:
- Place a bowl on your digital scale and tare it to zero.
- Crack the required number of eggs into the bowl. For example, if a recipe calls for two large eggs, aim for approximately 114 grams of whisked egg liquid.
- If you have too much, simply pour a small amount out. If you have too little, whisk another egg in a separate bowl and add a small amount until the desired weight is reached.
- This method ensures the precise ratio of moisture and leavening is maintained, guaranteeing a more consistent final product, whether it's cookies that don't spread too much or a genoise cake with perfect lift.
Cooking with the Correct Egg Weight
Measuring by weight is especially important for recipes where the egg's moisture and binding properties are critical for success, such as:
- Baking delicate cakes and pastries: Recipes like génoise, angel food cake, or soufflés rely on precise egg ratios for their light, airy structure.
- Making custards and creams: The balance of egg, sugar, and milk/cream is key to achieving the correct texture in items like crème brûlée or pastry cream.
- Creating pasta dough: The correct ratio of egg to flour is essential for the dough's workability and final texture.
- Crafting emulsions: Sauces like hollandaise or mayonnaise depend on the emulsifying properties of eggs. Inaccurate egg quantities can cause the emulsion to break.
Conclusion: Precision Leads to Perfection
In conclusion, while an average of 114 grams is a good starting point for two large eggs, the actual weight can vary based on regional standards, hen age, and other factors. For the most consistent and professional baking results, the definitive answer to "how many grams is 2 large eggs?" is to measure them with a digital kitchen scale. This simple practice ensures you have the exact amount of egg needed, guaranteeing predictable and delicious outcomes every time.

Egg Size Comparison Table
For reference, here is a comparison of different egg sizes and their approximate weights, based on common standards.
| Egg Size | Weight per Egg (Approximate) | Two Eggs (Approximate) |
|---|---|---|
| Small | ~43-47 grams | ~86-94 grams |
| Medium | ~50-54 grams | ~100-108 grams |
| Large | ~57-61 grams | ~114-122 grams |
| Extra Large | ~64-68 grams | ~128-136 grams |
| Jumbo | ~71+ grams | ~142+ grams |
The Breakdown of Two Large Eggs
For those curious about the components, the edible portion of two large eggs is also quantifiable by weight. A large egg white is approximately 30 grams, and a large yolk is about 18 grams. Therefore, two large eggs (approximately 114g total) would break down to roughly:
- Total Edible Weight: 108g (with about 6g attributed to the shells)
- Egg Whites: ~60g
- Egg Yolks: ~36g
The Difference in Egg Weight and Baking Success
While the difference between a large egg and an extra-large egg might seem trivial for a simple omelet, it can have a tangible effect on baking. Using larger eggs than a recipe specifies can add excess moisture, potentially leading to a denser or flatter final product, such as cookies that spread too much. Conversely, using eggs that are too small can result in a drier baked good with less lift. For consistency, especially when relying on a recipe with a fine balance of ingredients, weighing is the most reliable method.
How to Adjust Your Recipe
If you find yourself with the wrong size eggs, you can adjust the total amount to match the required weight. As mentioned, two large eggs typically equate to about 114 grams. If you only have extra-large eggs, which average around 64 grams, you can beat one and a half eggs and weigh it to get closer to the 114-gram target. This ensures that the ingredient ratios stay consistent with the recipe's original intent.
The Takeaway for Home Cooks and Bakers
For most everyday cooking, such as scrambled eggs or frittatas, a slight variation in egg size is inconsequential. However, for precision baking, relying on a consistent weight is a professional technique that can elevate your results. A simple digital kitchen scale is an affordable tool that can significantly improve the quality and consistency of your baked goods. Investing in one is a small step that can make a big difference in your kitchen.
