What the sources say egg whites weighs
Published values, quoted at the exact measure each source lists. Sources round differently and assume different fill techniques — which is why they rarely agree to the gram.
| Source | Listed measure | Weight |
|---|---|---|
| USDA FoodData Central | 1 large white | 33 g |
| USDA FoodData Central | 1 cup | 243 g |
| King Arthur Baking | 1 large whiteKing Arthur publishes a range of 30–35 g. | 33 g |
CupOrGram standardizes on 243 g per cup (15 g per tablespoon, 5 g per teaspoon) and uses that single value on every page — how we reconcile the sources.
Why this conversion varies
Egg Whites can vary by brand and measuring style.
- Egg Whites may settle, compress, or pour differently based on handling.
- egg whites can shift with temperature and ingredient texture.
- This page uses a consistent 243 g per cup baseline for repeatable conversions.
Why this conversion matters
Egg Whites can behave differently by brand and handling. Converting egg whites with a consistent baseline gives you a more dependable starting point for scaling recipes.
Practical baking use
Fresh egg whites, measured by weight because eggs are not a standard size. The structural protein behind meringue, pavlova, angel food cake, and macarons. Use this conversion as a practical starting point for scaling recipes with egg whites.
- If consistency matters, verify with a small test batch first.
- Use weight-based measurements when precision is critical.

Recipe Context for Egg Whites
For chemical leavening: small weight changes alter rise and browning.
For quick breads: over-leavening can cause collapse after oven spring.
For cookies: balance leavening with acid source for predictable spread.
Common Pitfalls
- Switching brands without re-checking weight can change texture and bake time.
- Using volume-only measurements for dense ingredients can overshoot recipe targets.
- Expired leaveners can underperform even when measured correctly.
Brand Variance Example
Baseline on this page: 1 cup egg whites = 243g. Real-world range can shift by about 6% because fine powders and leaveners settle during storage, changing cup density.
Example for 2 cups: baseline 486g, common range 456g-516g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
