Medium vs large egg calories differ slightly but significantly when tracking macros. A medium egg contains about 63 calories, while a large egg contains about 72 calories, based on USDA standards. The difference comes from egg weight, not shell size appearance. Choosing large instead of medium eggs adds roughly 9 calories per egg, which can significantly affect totals when eating multiple eggs.
Medium vs Large Egg Calories

Medium egg: ~63 calories
-
Large egg: ~72 calories
-
Difference: ~9 calories per egg
-
Calories scale by weight, not brand
-
Size confusion is a common tracking mistake
Why People Get Confused About Egg Sizes and Calories
At first glance, medium and large eggs look almost identical. However, nutrition labeling doesn’t work visually — it works by weight.
Moreover, most recipes, calorie apps, and restaurant estimates automatically assume large eggs, even when people use medium eggs at home. As a result, calorie tracking errors quietly compound.
Therefore, understanding this distinction is essential for:
-
Accurate calorie counting
-
Macro tracking
-
Portion consistency
-
Recipe nutrition accuracy
USDA Definition: Medium vs Large Eggs Explained
The USDA defines egg sizes strictly by minimum weight per egg, not shell diameter.
| Egg Size | Average Weight | Calories (Whole Egg) |
|---|---|---|
| Medium | ~44 grams | ~63 calories |
| Large | ~50 grams | ~72 calories |
Key insight:
That 6-gram difference doesn’t sound large. However, fat and protein are energy-dense. Consequently, even small weight changes affect calorie totals.

Medium vs Large Eggs: Side-by-Side Nutrition Comparison
Calories aren’t the only difference — nutrients scale with size as well.
| Nutrient | Medium Egg | Large Egg |
|---|---|---|
| Calories | ~63 | ~72 |
| Protein | ~5.5 g | ~6.3 g |
| Fat | ~4.5 g | ~5 g |
| Cholesterol | Lower | Slightly higher |
| Micronutrients | Moderate | Slightly higher |
As a result, large eggs provide more nutrition per egg, not just more calories. Therefore, choosing large eggs isn’t inherently “worse” — it’s simply more energy-dense.
What Happens When You Eat Multiple Eggs?
This is where the difference becomes meaningful.
| Eggs Eaten | Medium Eggs | Large Eggs |
|---|---|---|
| 2 eggs | ~126 cal | ~144 cal |
| 3 eggs | ~189 cal | ~216 cal |
| 4 eggs | ~252 cal | ~288 cal |
| 6 eggs | ~378 cal | ~432 cal |
Why this matters:
At higher portions, choosing large eggs instead of medium eggs can add 40–60 extra calories. Consequently, people often exceed calorie targets without realizing it.
Which Is Better for Weight Loss: Medium or Large Eggs?
There’s no universal “better” option — only better alignment.
Medium eggs may be better if:
-
You’re in a strict calorie deficit
-
You eat multiple eggs daily
-
You want tighter portion control
Large eggs may be better if:
-
You want more protein per egg
-
You eat fewer eggs overall
-
You prioritize nutrient density
According to Harvard T.H. Chan School of Public Health, satiety and nutrient quality matter just as much as calorie count. Therefore, food choice should match dietary goals, not fear calories.
Cooking Method Doesn’t Change the Size Difference
Regardless of preparation, the calorie gap remains.
| Cooking Method | Medium Egg | Large Egg |
|---|---|---|
| Raw | ~63 | ~72 |
| Boiled | ~63–66 | ~72–75 |
| Poached | ~63 | ~72 |
| Fried (no oil) | Slightly higher | Slightly higher |
However, added fats affect both equally. Consequently, cooking oil often matters more than egg size.
Mayo Clinic consistently highlights this distinction in calorie-conscious cooking guidance.
Common Mistakes People Make with Egg Sizes
Even experienced trackers make these errors:
-
Assuming “large” is default everywhere
However, many grocery eggs are medium. -
Ignoring size in calorie apps
Consequently, logs become inaccurate. -
Switching sizes without adjusting calories
As a result, weekly totals drift upward. -
Over-focusing on calories alone
Meanwhile, nutrition quality gets ignored.
People Also Ask
Are medium eggs lower in calories than large eggs?
Yes. Medium eggs contain about 9 fewer calories per egg compared to large eggs.
Why do calorie labels assume large eggs?
Because USDA nutrition labeling standards use large eggs as the reference size.
Does egg size affect protein intake?
Yes. Large eggs provide slightly more protein than medium eggs.
Should I always choose medium eggs to save calories?
Not necessarily. The difference is small per egg and should align with total diet goals.

What This Means for You
A medium egg contains about 63 calories, while a large egg contains about 72 calories. Although the difference seems small, it adds up quickly when eating multiple eggs. Therefore, understanding egg size helps you track calories more accurately — without sacrificing nutrition.

The information provided regarding Medium vs Large Egg Calories is for educational purposes and is based on 2025 USDA nutritional standards for large and medium eggs. It is important to note that calorie counts can vary slightly depending on the specific weight of the egg and the brand purchased. Because individual dietary needs are influenced by factors such as age, metabolism, and activity level, the data on Medium vs Large Egg Calories should not be used as a substitute for professional medical advice or personalized guidance from a registered dietitian. Additionally, preparation methods—such as using oil, butter, or milk—will change the final nutritional value beyond the base Medium vs Large Egg Calories mentioned here.
