Understanding Egg Weight Standards
For many home cooks and professional bakers, the term 'large egg' is a standard unit of measurement. However, in the world of precise recipes, especially in baking, relying on a vague size can lead to inconsistent results. The USDA grades eggs by the total weight of a dozen, not the size of individual eggs, which means there can be slight variations within a single carton. For consistency, particularly in baking where chemical reactions are sensitive to ingredient ratios, knowing the specific weight in grams is far superior to counting by number.
Why Egg Weight Varies
Several factors contribute to the weight of an individual egg, meaning that even a large egg might not be exactly 56.7 grams. Some of these factors include:
- Age of the Hen: A hen's age is the most significant factor affecting egg size. Younger hens, or pullets, lay smaller eggs, while older, more mature hens produce larger eggs. As a hen ages, the eggs she lays get progressively larger.
- Breed of the Hen: Certain breeds, such as Orpingtons or Jersey Giants, are naturally larger birds and tend to lay bigger eggs than smaller breeds.
- Nutrition: A hen's diet plays a critical role in her overall health and, consequently, the size of her eggs. High-quality feed with sufficient protein, fats, and amino acids can lead to larger eggs.
- Environmental Factors: External conditions like ambient temperature can influence egg size. For instance, extremely hot weather can decrease a hen's feed intake, leading to smaller eggs.
The Importance of Weighing Your Eggs
Recipes that call for a specific weight of eggs, rather than a number, are almost always more reliable. This is especially true for baking, where the balance of fats and moisture is critical for the final texture and structure. Here's a quick list of reasons to weigh your eggs instead of counting them:
- Improved Consistency: Achieve identical results every time, no matter the natural variation between individual eggs.
- Better Baking Outcomes: Ensure the proper moisture-to-flour ratio for everything from cakes to bread.
- Accurate Conversions: When scaling a recipe up or down, using weight is much simpler and more accurate than guessing the volume of a half-egg.
- Prevent Recipe Failure: For delicate dishes like soufflés or custards, a few grams can make the difference between a perfect result and a disappointing one.
A Practical Comparison of Egg Sizes
While this article focuses on large eggs, it's helpful to understand the full range of egg sizes and their average weights. This table uses approximate USDA standards, but remember that regional standards may vary.
| Egg Size | Average Weight per Egg (Approx. grams) | Average Weight per Egg (Approx. ounces) |
|---|---|---|
| Jumbo | 70.9 g | 2.5 oz |
| Extra-Large | 63.8 g | 2.25 oz |
| Large | 56.7 g | 2.0 oz |
| Medium | 49.6 g | 1.75 oz |
| Small | 42.5 g | 1.5 oz |
| Peewee | 35.4 g | 1.25 oz |
For a 2 large egg recipe, using 113.4 grams of weighed, shelled egg is the most reliable approach. You can achieve this by cracking your eggs into a bowl, whisking them together, and then weighing out the precise amount needed.
How to Adapt Recipes for Egg Weight Variations
If you find yourself with eggs that are not the standard 'large' size and a recipe doesn't provide a weight, you can adjust accordingly. For example, if you only have extra-large eggs, you can use one and a half eggs for a recipe calling for two large ones. The reverse is also true; for smaller eggs, you may need an extra one to reach the correct mass. Another approach is to simply crack your eggs and measure out the required weight using a kitchen scale. For general cooking, such as scrambled eggs, the small differences are usually not a problem, but for precise applications like baking, a digital scale is your best friend.

Conclusion
To answer the question, "how many grams is a 2 large egg," the standard reference is 113.4 grams, based on the USDA minimum average of 56.7 grams per large egg. While this is a reliable guideline, remember that individual egg weights can vary naturally. For the best and most consistent results in your cooking and baking, especially for delicate or complex recipes, investing in a kitchen scale and measuring your eggs by weight is the most accurate method. This ensures that you're always working with the exact quantities the recipe intended, regardless of natural fluctuations in your carton of eggs.
