How to Use This Converter
Enter the number of eggs your recipe calls for, select the size the recipe specifies, then choose the size you have. The converter calculates exactly how many eggs to use and notes any adjustment tips for baking.
Most recipes are written for large eggs. If your recipe doesn't specify, assume large. This matters because the difference between sizes isn't small — a jumbo egg weighs nearly 65% more than a small one, so swapping sizes without adjusting the count can noticeably change a recipe's moisture and structure.
Does Egg Size Actually Matter?
For most cooking — scrambled eggs, fried eggs, omelettes — the difference between sizes is small enough not to matter. For baking, it can matter significantly. Eggs provide structure, moisture, fat, and leavening in baked goods. Using fewer, larger eggs versus more, smaller ones changes the ratio of yolk to white, which changes texture.
For recipes using 1–2 eggs, swapping one size adjacent (large for extra large, or large for medium) is generally fine without adjustment. For recipes using 4+ eggs, precision matters more — especially in delicate cakes, custards, and soufflés.
The effect compounds with quantity. In a recipe calling for 6 large eggs, substituting 6 medium eggs instead means leaving out roughly 42g of liquid — nearly a full extra egg's worth. That's enough to throw off a soufflé or a custard-based dessert, but rarely noticeable in a batch of scrambled eggs or a frittata.
How Egg Size Labeling Actually Works
In the US, egg size is set by USDA weight-per-dozen standards, not by the size of an individual egg. A dozen "large" eggs must weigh at least 24 oz total (2 oz per egg on average), while a dozen "medium" eggs must weigh at least 21 oz. This means two eggs labeled the same size can still vary in weight by several grams — the standard is an average across the carton, not a per-egg guarantee. If a recipe's outcome is sensitive to egg size (soufflés, macarons, angel food cake), weighing your eggs out of the shell is more reliable than trusting the carton label alone.
This is also why swapping between egg brands of the "same" size can occasionally give slightly different results — one carton's large eggs might run closer to 55g each while another runs closer to 60g, both within the USDA large range.
What to Do When a Recipe Doesn't Specify a Size
Older or handwritten recipes often just say "eggs" with no size noted. In that case, large is the safest default for any US recipe written after the 1970s, when large became the de facto standard for recipe development and grocery store stocking. For very old recipes (pre-1950s), eggs were often smaller on average — treating them as medium is usually closer to the original intent.
US and UK/EU egg sizing don't line up exactly. A US "large" egg (57g) is close to a UK/EU "medium" egg (53–63g), not a UK "large" (63–73g). If you're following a US recipe with UK eggs, use UK medium eggs where the recipe calls for US large, and adjust up one size for anything labeled extra-large or jumbo. This mismatch is one of the most common sources of confusion when following recipes across regions.
Frequently Asked Questions
Can I use 2 medium eggs instead of 1 large egg?
Not exactly — 2 medium eggs is about 100g, while 1 large egg is about 57g. That would nearly double the egg content. For substituting 1 large egg with medium eggs, use 1 medium egg plus about 1 teaspoon of beaten egg from a second one.
What size eggs do most recipes use?
The vast majority of US baking and cooking recipes are written for large eggs. If a recipe doesn't specify size, large is the safe assumption.
Are jumbo eggs worth using in baking?
Not usually — the extra volume can throw off the liquid balance in baked goods. Jumbo eggs are better suited to savory cooking where precision matters less. For baking, stick to large or extra large.
How many large eggs equal 3 medium eggs?
3 medium eggs (about 150g) equal roughly 2.6 large eggs — in practice, use 2 large eggs plus about 2 tablespoons of beaten egg from a third. For a full breakdown of egg size substitutions with more examples, see our egg size substitution guide.
How many small eggs equal 2 large eggs?
2 large eggs (about 114g) equal roughly 2.7 small eggs — in practice, use 2 small eggs plus about 2 tablespoons of beaten egg from a third. Small eggs average 43g versus 57g for large.
How many medium eggs equal 2 large eggs?
2 large eggs (about 114g) equal roughly 2.3 medium eggs — in practice, use 2 medium eggs plus about 1 tablespoon of beaten egg from a third. Medium eggs average 50g versus 57g for large.
How long do eggs last in the fridge, and does size change that?
Egg size doesn't affect shelf life. Fresh eggs in their shell keep for 3-5 weeks in the refrigerator (at or below 40°F) regardless of whether they're small, medium, large, or jumbo, per USDA guidance. Hard-boiled eggs, in or out of the shell, last about 1 week. Don't wash eggs before storing them — it removes the natural protective coating and shortens shelf life.
