Cappuccino vs Latte: What's Actually Different?

Cappuccino and latte are the two espresso-and-milk drinks ordered most often at Canadian coffee shops. They use the same shot of espresso (1 oz, ~63 mg caffeine) but very different proportions of steamed milk and foam, which is why one comes out as a 5-ounce drink with a thick foam crown and the other comes out as a 12-ounce mug of mostly milk.

The Italian textbook definitions

Cappuccino: 1 oz espresso, 2 oz steamed milk, 2 oz milk foam. ~5 oz total. Equal thirds.

Latte: 1 oz espresso, 8–10 oz steamed milk, ~½ oz foam (a thin micro-foam layer). ~10–12 oz total.

Italian cappuccino is small, served in a 5-ounce ceramic cup, never bigger. North American “cappuccino” at chains like Tim Hortons is often a 12-ounce drink with the same proportions stretched thin — closer to a flat white with extra foam.

Calories and macros, side-by-side (with 2% milk)

Cappuccino, 5 oz, 2% milk: ~70 calories, 4 g protein, 6 g carbs, 2.5 g fat

Latte, 12 oz, 2% milk: ~150 calories, 8 g protein, 13 g carbs, 5 g fat

A latte has roughly twice the calories of a cappuccino for the same espresso shot, because it has twice the milk.

A latte does have meaningful protein (8 g) — it is closer to a small dairy snack than to coffee.

Caffeine content

Both drinks have the same 1 shot of espresso (~63 mg of caffeine) at most North American chains. Italian standards use a slightly lighter roast and ~80 mg per shot.

A double-shot (doppio) cappuccino or latte has ~125 mg of caffeine — more than a 12-oz drip coffee (~95 mg).

Decaf espresso has ~5 mg per shot, not zero.

Texture and how to order

If you want coffee with milk: latte. The milk dominates and the espresso plays a supporting role.

If you want espresso with the bitterness softened: cappuccino. The thick foam concentrates the espresso flavour and adds a distinct texture.

If you want strong coffee with very little milk: cortado (1:1 espresso to milk, no foam) or macchiato (espresso with a dollop of foam).

If you want a North-American “creamy” drink: flat white. Same milk-to-coffee ratio as cappuccino but with micro-foam instead of thick foam.

Plant-milk swap

Oat milk lattes (Oatly, Earth’s Own Barista) are roughly the same calorie count as 2% milk lattes. Slightly less protein (3 vs 8 g), slightly more sugar.

Almond milk lattes are dramatically lower-calorie (~50 cal for a 12 oz) but offer almost no protein.

Soy milk is the closest to dairy on protein (7 g). A soy latte is the closest plant-milk equivalent to a regular latte.

The bottom line

Order a cappuccino if you want a small, espresso-forward drink and a latte if you want a creamy coffee that doubles as a small breakfast. The North American 12-ounce “cappuccino” is closer to a latte; if you want the Italian original, ask for a small.
