Egg Size Conversion Chart: Weights and Substitutions

A large egg weighs about 57 g in the shell and about 50 g out of it, split into roughly 33 g of white and 17 g of yolk. When a recipe just says "egg", North American recipes mean large; British recipes usually mean medium, which is about the same size.

Canadian egg grades by weight

Canada grades Grade A eggs by the weight of each individual egg, in the shell.

Canada size Weight per egg (in shell)
Jumbo 70 g or more
Extra large 63–69 g
Large 56–62 g
Medium 49–55 g
Small 42–48 g
Peewee Less than 42 g

US egg sizes

The US sizes eggs by minimum weight per dozen, so individual eggs in a carton can vary a little.

US size Minimum per dozen Average per egg, minimum (in shell)
Jumbo 30 oz (850 g) 71 g
Extra large 27 oz (765 g) 64 g
Large 24 oz (680 g) 57 g
Medium 21 oz (595 g) 50 g
Small 18 oz (510 g) 43 g
Peewee 15 oz (425 g) 35 g

UK and EU egg sizes

UK/EU size Weight per egg (in shell) Closest North American size
Very large 73 g and over Jumbo
Large 63–73 g Extra large
Medium 53–63 g Large
Small Under 53 g Medium

So a UK recipe asking for "2 large eggs" wants eggs closer to North American extra large.

What's inside: whole, white and yolk

The shell is roughly 10–12% of the egg's weight. These are typical figures out of the shell.

Size Whole egg White Yolk Volume (whole, beaten)
Medium 44 g 29 g 15 g about 3 tbsp
Large 50 g 33 g 17 g about 3¼ tbsp (48 mL)
Extra large 56 g 37 g 19 g about 3¾ tbsp
Jumbo 63 g 42 g 21 g about 4¼ tbsp

Handy volumes: 1 cup holds about 5 large whole eggs, 7–8 large whites, or about 14 large yolks.

Swapping egg sizes

Use this when your carton doesn't match the recipe.

Recipe says (large) Jumbo Extra large Medium Small
1 1 1 1 1
2 2 2 2 3
3 2 3 3 4
4 3 4 5 5
5 4 4 6 7
6 5 5 7 8

For one or two eggs, size rarely matters except in custards and meringues. For bigger quantities, or recipes where eggs are the structure (sponge cake, soufflé, choux pastry), weigh instead: multiply the number of large eggs by 50 g, then beat and weigh your eggs to match.

Why egg size matters in baking

Eggs are about 75% water, so an extra 10 g of egg per egg is extra liquid in the batter. They also bring protein that sets into structure as it denatures and lecithin-rich yolks that act as an emulsifier. Too much egg can make cakes rubbery or eggy; too little can make them crumbly and flat.

Whites and yolks behave differently, too. Whites are mostly water and protein and whip into foams for meringue. Yolks are about one-third fat and enrich custard and sauces.

Storage and safety

In Canada and the US, eggs are washed before sale, which removes their natural protective coating, so keep them in the fridge at 4 °C (40 °F) or below. Cook egg dishes to 74 °C (165 °F) per Health Canada, or until the white and yolk are firm. Use pasteurized eggs for anything served raw, such as homemade mayonnaise or mousse, if serving young children, pregnant people or older adults.

Questions

What size egg do recipes mean if they don't say?

North American recipes assume large eggs, about 50 g each out of the shell. UK recipes usually assume medium eggs, which are about the same size as a North American large.

How many medium eggs equal 2 large eggs?

Two medium eggs can replace two large eggs in most recipes. From three large eggs upward, the difference adds up; for four large eggs use five medium.

How much does an egg white weigh?

The white of a large egg weighs about 33 g (about 2 tablespoons), and the yolk about 17 g (about 1 tablespoon).

How do I use half an egg?

Beat the egg, weigh it (about 50 g for a large egg) and use half, about 25 g. Without a scale, a beaten large egg is a little over 3 tablespoons, so use about 1½ tablespoons.
