Egg Size to Grams: White, Yolk & Edible Weight

Q: How many grams is a large egg?

A USDA Large egg weighs approximately 57 grams with the shell . The edible portion (white + yolk) is about 52 grams : roughly 33 g of white and 18 g of yolk. The shell accounts for ~5 g (~9% of total weight). Most American and many international recipes use Large as the default when no size is specified.

Q: How much does an egg yolk weigh?

Yolk weight is approximately 31% of the whole egg's weight (USDA FoodData Central). For common sizes: Medium yolk ≈ 16 g , Large yolk ≈ 18 g , Extra Large yolk ≈ 20 g , Jumbo yolk ≈ 22 g . The proportion stays consistent across sizes — only absolute grams change.

Q: How do I substitute Medium eggs for Large eggs in a recipe?

Match the total edible weight , not the unit count. Four Large eggs provide about 4 × 52 g = 208 g edible. Medium eggs yield ~46 g edible each, so you need 208 ÷ 46 ≈ 4.5 → use 5 Medium eggs . For casual cooking (scrambled eggs, frittata) one extra egg rarely matters; for technical baking (chiffon cake, soufflé, custard) the extra mass changes moisture balance and structure.

Q: How many grams of egg white do I need for French macarons?

Classic French macaron recipes typically call for 90–100 g of aged egg whites for a standard batch of 30–36 shells. With Large eggs (~33 g white each), that's 3 eggs (99 g). With Medium eggs (~29 g each), you'd need 4 eggs (116 g, with ~16–26 g leftover). Most pastry chefs recommend weighing, not counting, and aging whites uncovered in the fridge for 24–48 hours before use.

Q: Does egg freshness affect the weight or white-to-yolk ratio?

Egg weight decreases slightly over time as moisture evaporates through the porous shell — a loss of 2–4 g over shelf life. The white-to-yolk mass ratio stays essentially constant, but texture changes: older eggs have more liquid white (thick albumen converts to thin albumen), which can be useful for macarons because the whites flow more easily. For precision baking, always check the weight, not just the size on the carton.

Q: How do USDA egg sizes compare to European egg sizes?

The EU uses a different grading system: S ( 73 g) . A European 'L' (63–73 g) is heavier than a USDA 'Large' (~57 g) and closer to USDA Extra Large. When following a European recipe that calls for 'L' eggs, use USDA Extra Large or Jumbo for the closest match. When in doubt, convert the recipe to grams rather than unit count.

Q: What are the calories in egg white vs. egg yolk?

Per USDA FoodData Central: egg white ≈ 52 kcal per 100 g (mostly protein, virtually no fat). Egg yolk ≈ 322 kcal per 100 g (~27% fat, significant cholesterol). A whole Large egg (edible ~52 g) contains about 72–75 kcal total . Knowing the exact gram weight — what this calculator provides — makes it straightforward to track macros for either component.

Q: How much does a dozen eggs weigh?

Per USDA minimum weight standards per dozen: Small ≈ 510 g , Medium ≈ 595 g , Large ≈ 680 g , Extra Large ≈ 765 g , Jumbo ≈ 850 g . These are minimums — actual cartons may be slightly heavier. The per-egg averages used in this calculator (43 g, 50 g, 57 g, 64 g, 71 g) are derived from the midpoint of each USDA dozen-weight band divided by 12.

How many grams is a Large egg? White ≈ 33 g, yolk ≈ 18 g, edible ≈ 52 g. Full USDA size-to-grams chart (Small → Jumbo) + free calculator for baking and meal prep.

A USDA Large egg (the default for most recipes) yields about 33 g of white, 18 g of yolk, and 52 g of edible weight. Pick any size below to get the exact grams — essential for macarons, soufflés, and high-protein meal plans where counting eggs isn't precise enough.

Egg sizes follow USDA standards based on minimum weight per dozen: Small ≈ 43 g, Medium ≈ 50 g, Large ≈ 57 g, Extra Large ≈ 64 g, Jumbo ≈ 71 g (all weights include the shell). When a recipe says 'one egg' without specifying size, it means Large.

The weight is distributed in stable proportions regardless of size: shell ≈ 9%, white ≈ 58%, yolk ≈ 31% — sourced from USDA FoodData Central (SR Legacy #01123). Choose size and count; get grams instantly.

When to use this calculator

Recipe calls for 90 g egg whites for French macarons: with Large eggs (~33 g white each) you need 3 eggs (99 g) — the calculator shows exactly how much you get and how much is left over.
A European recipe specifies '4 Medium eggs' but you only have Extra Large: 3 XL eggs provide almost the same total edible weight, saving one egg.
Scaling a pastry recipe from 12 to 36 servings: convert to grams (3 × 33 g = 99 g white) and weigh directly for consistent results instead of counting.
Tracking macros on a high-protein plan: nutritionist specified 'white equivalent to 2 large eggs per day' — that's ~66 g, confirming how much liquid pasteurized white to use.

How It Is Calculated

The calculator uses the midpoint weight of each USDA category and applies the stable physiological proportions documented in USDA FoodData Central SR Legacy #01123:

White (g)   = whole_weight × 0.58 × count
Yolk (g)    = whole_weight × 0.31 × count
Edible (g)  = whole_weight × 0.91 × count

The remaining 9% is the shell. These proportions are practically constant across sizes — the only thing that changes is the total weight of the egg. In other words: a Jumbo egg does not have a proportionally larger yolk than a Large one; it simply weighs more overall.

Why Egg Size Matters in Recipes

Most English-language recipes assume a Large egg (57 g). If you use a different size without adjusting, the impact is real:

Swapping 3 Large eggs for 3 Medium means using ~18 g less total mass (~6 g less white). In sponge cakes or macarons that can affect the structure.

Swapping 3 Large for 3 XL adds ~21 g extra, which in a tightly balanced batter can create excess moisture.

Practical substitution rule by egg-white weight:

You need (Large)	You can use (Medium)	You can use (XL)
2 eggs (~66 g white)	3 eggs (~87 g) — excess	2 eggs (~74 g) — slight excess
4 eggs (~132 g white)	5 eggs (~145 g)	4 eggs (~148 g)

For recipes where exact weight is critical, it is always better to weigh the whites or yolks rather than count eggs.

Context: commercial eggs in the EU and Argentina

USDA standards do not apply directly outside the US. In the EU, Regulation EC 589/2008 defines: S (<53 g), M (53–63 g), L (63–73 g), XL (≥73 g). In Argentina, SENASA grades eggs by minimum weight (categories 1 to 4), where category 1 is ≥63 g — similar to the US XL.

Rough equivalence:

USDA	EU	Argentina approx.
Large (57 g)	M–L	Category 2–3
XL (64 g)	L	Category 1–2

If you use this calculator with European or Argentine eggs, pick the closest size by weight, not by the letter printed on the carton.

What This Calculator Does NOT Include

Variation by breed or feed: eggs from free-range hens or Araucana breeds can have proportionally larger yolks. The USDA figures are industrial-production averages.

Eggs from other birds: the proportions for quail, duck or goose differ significantly. A quail egg (~9 g) has a yolk share of around 36–38% of the edible weight.

Weight after cooking: the water in the white evaporates as it cooks. A 33 g raw white can weigh ~27–29 g cooked depending on the method.

Nutritional value: for calories, protein or cholesterol, check USDA FoodData Central directly (fdc.nal.usda.gov).

Common Mistakes When Weighing Eggs

1. Weighing with the shell and not deducting it. The shell is ~9% of total weight; if you weigh the whole unbroken egg, the real edible weight is total_weight × 0.91.
2. Assuming every egg in the same carton weighs the same. Within a single USDA category there is a range of ±5–7 g. For recipes that call for >200 g of white, always weigh.
3. Confusing "1 white" with "30 g". It is a common approximation in European recipes, but it corresponds to a small Medium egg. The white of a standard Large is ~33 g.

Example: French macarons — 90 g egg whites

Recipe calls for 90 g of egg white

Select: Large (L), quantity: 3 eggs

White total: 3 × 33 g = 99 g → 9 g leftover, save for another use

Yolk total: 3 × 18 g = 53 g

Total edible: 3 × 52 g = 156 g

3 Large eggs = 99 g white · 53 g yolk · 156 g edible total

Frequently asked questions

How many grams is a large egg?

A USDA Large egg weighs approximately 57 grams with the shell. The edible portion (white + yolk) is about 52 grams: roughly 33 g of white and 18 g of yolk. The shell accounts for ~5 g (~9% of total weight). Most American and many international recipes use Large as the default when no size is specified.

How much does an egg white weigh in grams?

Egg white weight depends on the size. Based on USDA data (white ≈ 58% of whole egg weight): Small ≈ 25 g, Medium ≈ 29 g, Large ≈ 33 g, Extra Large ≈ 37 g, Jumbo ≈ 41 g. For precision baking (macarons, Italian meringue), always weigh whites on a kitchen scale rather than relying on egg count alone.

How much does an egg yolk weigh?

Yolk weight is approximately 31% of the whole egg's weight (USDA FoodData Central). For common sizes: Medium yolk ≈ 16 g, Large yolk ≈ 18 g, Extra Large yolk ≈ 20 g, Jumbo yolk ≈ 22 g. The proportion stays consistent across sizes — only absolute grams change.

How do I substitute Medium eggs for Large eggs in a recipe?

Match the total edible weight, not the unit count. Four Large eggs provide about 4 × 52 g = 208 g edible. Medium eggs yield ~46 g edible each, so you need 208 ÷ 46 ≈ 4.5 → use 5 Medium eggs. For casual cooking (scrambled eggs, frittata) one extra egg rarely matters; for technical baking (chiffon cake, soufflé, custard) the extra mass changes moisture balance and structure.

How many grams of egg white do I need for French macarons?

Classic French macaron recipes typically call for 90–100 g of aged egg whites for a standard batch of 30–36 shells. With Large eggs (~33 g white each), that's 3 eggs (99 g). With Medium eggs (~29 g each), you'd need 4 eggs (116 g, with ~16–26 g leftover). Most pastry chefs recommend weighing, not counting, and aging whites uncovered in the fridge for 24–48 hours before use.

Does egg freshness affect the weight or white-to-yolk ratio?

Egg weight decreases slightly over time as moisture evaporates through the porous shell — a loss of 2–4 g over shelf life. The white-to-yolk mass ratio stays essentially constant, but texture changes: older eggs have more liquid white (thick albumen converts to thin albumen), which can be useful for macarons because the whites flow more easily. For precision baking, always check the weight, not just the size on the carton.

How do I convert eggs to grams of liquid pasteurized egg white?

Most commercial cartons of pasteurized liquid egg whites indicate how much equals one whole egg white (typically 30–35 ml or 30–35 g per large egg white). Use that stated equivalent rather than the fresh-egg weight, because pasteurized liquid whites may differ slightly in density. If the label is unclear, 33 g (Large) is a reliable starting point — but weigh and taste-check before committing to a full batch.

How do USDA egg sizes compare to European egg sizes?

The EU uses a different grading system: S (< 53 g), M (53–63 g), L (63–73 g), XL (> 73 g). A European 'L' (63–73 g) is heavier than a USDA 'Large' (~57 g) and closer to USDA Extra Large. When following a European recipe that calls for 'L' eggs, use USDA Extra Large or Jumbo for the closest match. When in doubt, convert the recipe to grams rather than unit count.

What are the calories in egg white vs. egg yolk?

Per USDA FoodData Central: egg white ≈ 52 kcal per 100 g (mostly protein, virtually no fat). Egg yolk ≈ 322 kcal per 100 g (~27% fat, significant cholesterol). A whole Large egg (edible ~52 g) contains about 72–75 kcal total. Knowing the exact gram weight — what this calculator provides — makes it straightforward to track macros for either component.

How much does a dozen eggs weigh?

Per USDA minimum weight standards per dozen: Small ≈ 510 g, Medium ≈ 595 g, Large ≈ 680 g, Extra Large ≈ 765 g, Jumbo ≈ 850 g. These are minimums — actual cartons may be slightly heavier. The per-egg averages used in this calculator (43 g, 50 g, 57 g, 64 g, 71 g) are derived from the midpoint of each USDA dozen-weight band divided by 12.
