Understanding egg sizing and weight
Egg sizes are not uniform, and they differ depending on the grading standards of different countries. For culinary and nutritional purposes, understanding the average weight for each size is key to accurate conversions. A large egg, which is the most common size used in American recipes, averages around 57 grams (2 ounces) when in its shell. However, this can vary slightly depending on the source.
The variable weight of eggs
The most significant factor affecting how many eggs are 100 grams is the size of the egg itself. The larger the egg, the fewer you will need to reach your target weight. For example, you would need fewer jumbo eggs than you would medium eggs to equal 100 grams. This variability is why professional bakers and serious home cooks often weigh ingredients rather than rely on volume or count.
Here are some common egg sizes and their approximate average weights, with and without the shell, based on US standards:
- Jumbo: ~71 grams (2.5 oz) in shell, ~63 grams without shell
- Extra-Large: ~64 grams (2.25 oz) in shell, ~56 grams without shell
- Large: ~57 grams (2 oz) in shell, ~50 grams without shell
- Medium: ~50 grams (1.75 oz) in shell, ~43 grams without shell
- Small: ~43 grams (1.5 oz) in shell, ~36 grams without shell
Calculating 100 grams based on egg size
Given the average weights, we can now determine how many eggs approximate 100 grams. Because you can't use a fraction of an egg without breaking it, you'll often end up with a number slightly over or under 100 grams, but it gives a practical estimate.
- For Large eggs (approx. 57g each), you will need roughly two eggs. This will give you approximately 114 grams of egg in total.
- For Medium eggs (approx. 50g each), you will also need approximately two eggs. This will give you a total of 100 grams.
- For Small eggs (approx. 43g each), you would need just over two eggs to reach 100 grams. Two small eggs would be 86 grams, while three would be 129 grams.
Using a kitchen scale for precision
For recipes where accuracy is crucial, such as baking, relying on average weights can lead to inconsistencies. A small kitchen scale is an affordable and invaluable tool for achieving precision. To measure 100 grams of egg precisely, crack one or two eggs into a bowl and weigh them. Add a second or third as needed, whisking them together to measure out the precise amount needed for the recipe.
Nutritional profile of 100 grams of eggs
Beyond simple measurement, understanding the nutritional value of a specific quantity is essential for a balanced nutrition diet. A 100-gram serving of eggs (roughly two medium or large eggs) is packed with high-quality protein and a variety of other essential nutrients.
- Protein: Approximately 12-13 grams of high-quality protein, which includes all nine essential amino acids.
- Calories: Around 143-145 calories.
- Vitamins: Rich in Vitamins D, A, E, B12, and Choline.
- Minerals: A good source of selenium, zinc, iron, and phosphorus.
Comparison of egg whites versus whole eggs per 100 grams
For those managing fat or calories, it's helpful to compare the nutritional breakdown of different egg components per 100 grams. The following table highlights the difference between whole eggs and egg whites only.
| Nutrient (per 100g) | Whole Egg | Egg White |
|---|---|---|
| Protein | ~13g | ~10.5g |
| Calories | ~143 kcal | ~53 kcal |
| Fat | ~10g | ~0g |
| Carbohydrates | ~1g | ~0.2g |
| Cholesterol | ~372mg | ~0mg |
| Choline | ~294mg | ~1mg |
This comparison shows that egg whites are a great option for a low-calorie, high-protein choice, while whole eggs offer a broader spectrum of nutrients, including healthy fats and choline.
Practical advice for using eggs in cooking
When you're trying to meet a specific weight for a recipe or nutritional goal, having a strategy helps. Here are some tips:
- For baking: Precision is paramount. Always use a digital kitchen scale for best results. Crack and whisk your eggs, then pour until you hit the exact 100-gram mark. You can save any leftovers for a different dish.
- For scrambling/omelets: Less precision is needed. The exact weight won't drastically alter the outcome. You can use two medium or large eggs and know you are getting very close to 100 grams.
- For protein boosting: If your goal is to add more protein to a meal, consider using egg whites. They offer a high protein-to-calorie ratio. You would need slightly more egg whites than whole eggs to achieve the same protein content, given the lower concentration per 100g.
Conclusion
To determine exactly how many eggs are 100 grams, you need to consider the size of the eggs being used. On average, two medium or large eggs will get you close to 100 grams, but a kitchen scale is the most accurate tool for precision. Given their rich profile of protein, vitamins, and minerals, incorporating 100 grams of eggs into your nutrition diet is an excellent way to boost your daily intake of essential nutrients. Whether you're a baker seeking precision or simply aiming to track your macros, understanding egg weights is a valuable piece of culinary knowledge.

Important takeaways on egg measurement
- Use a kitchen scale for accuracy: Relying on a kitchen scale to measure eggs by weight is the most precise method for consistent baking and cooking results.
- Egg size matters: The number of eggs per 100g varies greatly depending on their size (small, medium, large, etc.), so estimations based on counts are less reliable.
- Two eggs is a common approximation: For many recipes, two medium or large eggs will be very close to 100 grams in weight, making it a reliable general estimate.
- Nutrient density in 100g: A 100-gram serving of eggs provides a significant portion of daily protein, along with key vitamins and minerals like choline, vitamin D, and selenium.
- Whole vs. egg whites: For a lower-fat, lower-calorie protein source, use egg whites, but know they contain slightly less protein per 100g than whole eggs.
- Cooking doesn't change weight significantly: The mass of an egg does not change significantly when cooked, so 100 grams of raw egg will be approximately 100 grams when cooked.
- Different regions have different standards: Be aware that egg size classifications (e.g., Jumbo, Extra-Large) can differ by country, so it is always best to weigh if precision is needed.
