Egg Size to Grams: White, Yolk & Edible Weight
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.
A USDA Large egg (57 g with shell) yields approximately 33 g of white, 18 g of yolk, and 52 g of edible total. White = 58% of whole weight, yolk = 31%, shell = 9%. Medium eggs give ~29 g white; Extra Large ~37 g white.
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.
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

How the calculation works
The calculator uses USDA midpoint weights per size, then applies stable physiological proportions from 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 × countThese proportions are constant across sizes — only the whole-egg weight changes.

Multiple-egg white reference (Large eggs)
| Eggs (Large) | White (g) | Typical use |
|---|---|---|
| 1 | ~33 g | Glaze, small meringue |
| 2 | ~66 g | Angel food slice, protein shake |
| 3 | ~99 g | Standard macaron batch |
| 4 | ~132 g | Pavlova, large meringue |
| 6 | ~198 g | Full pavlova, Italian meringue |
| 12 | ~396 g | Large bakery batch |

Common mistakes
1. Treating size labels as interchangeable: A Medium egg (50 g) gives 29 g white; a Large (57 g) gives 33 g — 14% difference that matters in delicate meringues and emulsions.
2. Forgetting shell weight: ~9% of the whole egg is shell. A 57 g egg yields only ~52 g edible. This causes shortfalls when scaling large batches.
3. Mixing liquid pasteurized whites with fresh weights: Most commercial cartons specify the equivalent (e.g., '3 tablespoons = 1 large egg white'). Use that label figure, not a fresh-egg calculation.
4. Scaling by unit count instead of weight: When tripling a recipe, cracking 9 instead of 3 eggs can introduce ±30 g variation if sizes vary. Convert to grams, weigh, and eliminate uncertainty.

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.
