How Much Protein Is in an Egg White? By Size, Calories

A large egg white provides about 3.0 grams of protein.6 grams in one large raw white, which weighs roughly 33 grams. The amount rises with egg size, so a small white has less and a jumbo white has more. The same white provides about 17 calories.

This breakdown covers sizes, calories, labels, cooking, and serving calculations for your meals, whether you use fresh eggs, packaged whites, or restaurant portions.

The Large White Baseline

Weighing 33 grams, a large raw egg white supplies roughly 3.6 grams of protein.6 grams of protein. That estimate covers the white alone, excluding the shell and yolk, and gives you a practical starting point for recipes, food logs, and meal planning.

Egg white supplies high-quality protein with very little fat. It also contains all nine essential amino acids, which makes it a complete protein. The yolk provides some protein, but it carries nearly all the fat and dietary cholesterol in a whole egg, along with nutrients such as vitamin D, iron, and choline.

Your food log can use 3.6 grams whenever you lack a measured value for a large raw white. Individual eggs vary because of size, age, and breed, so treat the number as an estimate rather than a precise measurement for every egg.

“Use 3.6 grams as a baseline, not a guarantee. One large egg can contain slightly more or less protein than another egg graded as large.

Size Determines How Much You Get

A smaller white contains less protein because it weighs less, while a jumbo white usually contains more. Weight does not translate perfectly into nutrients, but the difference is meaningful when comparing a standard large white with a much smaller or larger one.

Your carton can classify several differently sized eggs as “large” without guaranteeing identical nutrition. Egg grading standards address size and quality rather than exact nutrient content, so a measured value may differ from 3.6 grams by a few tenths of a gram.

Packaged whites may give you a more precise figure because the manufacturer measures a defined serving. A carton can report protein per fluid ounce, while another package may use a 50- or 60-gram serving. Check the unit before calculating the amount on your plate.

Calories and Protein by Serving

One large raw egg white provides about 17 calories and 3.6 grams of protein. Its negligible fat and carbohydrate content gives you a higher protein-to-calorie ratio than many foods, although the nutrient profile does not make it a complete meal by itself.

The white alone contains no cholesterol. Nearly all dietary cholesterol and fat in a whole egg remains in the yolk, which contributes about 2.4 grams of the egg’s 6 grams of protein. Your choice depends on whether you want the white’s concentrated protein or the yolk’s wider nutrient mix.

A 100-gram serving of raw egg white contains approximately 11 grams of protein. You rarely eat that exact weight, though, so one 33-gram white is usually more useful than the 100-gram database figure for estimating an ordinary breakfast serving.

Protein quality matters alongside quantity. Egg protein provides essential amino acids in a useful pattern, including leucine, which contributes to muscle protein synthesis. Your broader intake should still vary across dairy, beans, fish, poultry, meat, soy, and plant-based foods.

Cooking Changes Weight More Than Protein

The 17-calorie baseline describes a raw white weighing about 33 grams. Heating can remove water, so a cooked white may weigh 30 to 33 grams while retaining close to the same 3.5 to 3.6 grams of protein.

A hard-boiled, microwaved, or pan-cooked white can finish at a different weight because each method removes a different amount of moisture. You can still use 3.6 grams for most tracking, but weigh the cooked portion when your training or calorie records require a more precise value.

Raw eggs can carry Salmonella even when the shell looks clean, and uncooked egg white is not safe to consume by itself. Thorough heating or pasteurization reduces that risk. These precautions align with food-safety guidance from the U.S. Food and Drug Administration.

Once cooked egg whites become part of your meals, their protein content can help you set a realistic daily target.

“Cook the white until firm, or choose pasteurized liquid whites. Keep raw eggs refrigerated, and wash your hands, utensils, and surfaces after handling them.

Calculating a Protein Target

A cooked large white still supplies roughly 3.6 grams, so you can use the same per-white estimate for raw and cooked meals. Three whites provide about 11 grams, four provide about 14 grams, and seven reach approximately 25 grams.

Divide your desired amount by 3.6 to estimate the number of large whites. A 20-gram target requires about 5.6 whites, making six the practical count. A 30-gram target requires about 8.3 whites, so nine produces the closer result.

Fresh eggs, liquid cartons, and restaurant dishes do not use identical serving conventions. A package may define one serving as 60 grams of liquid, while an omelet may contain three, five, or more whites. Your food record should reflect the actual quantity rather than the word “egg.”

• ▸Count large whites: Multiply each raw or cooked large white by about 3.6 grams of protein.
• ▸Check carton weight: Use the package’s grams, fluid ounces, and stated protein amount to calculate each serving.
• ▸Estimate restaurant meals: Treat a multi-white omelet as several eggs unless the menu lists a precise weight.
• ▸Round upward: Choose the next whole white when a target lands between two serving amounts.
• ▸Build a full plate: Add vegetables, fruit, whole grains, beans, or another protein source for variety and fiber.

Your body weight, age, activity level, and health needs influence your daily protein target. The National Institutes of Health and its Office of Dietary Supplements consider those factors, but they do not change the practical estimate of 3.6 grams for a large egg white.

Confirming Values With Labels and USDA Data

Your package label can refine the 3.6-gram estimate because it applies to a measured serving. Find the serving weight first, then check whether the protein statement refers to one serving, 100 grams, or another basis.

For a carton that lists 5 grams of protein in a 50-gram serving, a 240-gram container would provide about 24 grams. The arithmetic changes when a label uses fluid ounces or a serving count, so your calculation must follow the unit printed on the package.

For a fresh large white, you can enter a 33-gram serving with about 3.6 grams of protein. USDA FoodData Central provides separate entries for raw, cooked, and prepared egg whites, but its sample sizes and preparation methods can produce slightly different estimates.

• ▸Find the serving size: Distinguish the weight of the white from the grams of protein listed for it.
• ▸Match the form: Select raw, cooked, pasteurized, or prepared data that corresponds to what you eat.
• ▸Scale the container: Compare the total package weight with the weight of one stated serving.
• ▸Count the whites: Apply 3.6 grams to each large white only when you lack package or database information.
• ▸Record uncertainty: Treat estimated restaurant portions as ranges rather than exact nutrient totals.

A typical 240-gram liquid carton can contain more than 20 grams of protein, but the total depends on the product. By comparison, seven large whites reach 25 grams. Your best number comes from the label or measured food rather than either serving category alone.

Bottom Line

Use about 3.6 grams of protein and 17 calories for one large raw egg white. Small and jumbo whites generally provide about 3 and 4.5 grams, respectively, while cooking mainly changes moisture and weight. Prefer your package value when available, and pair whites with carbohydrates, produce, and varied protein sources.
