Latte vs Cappuccino vs Flat White: Milk Ratios and Sizes Compared
A cappuccino is a smaller drink (about 150–180 ml) with a thick, airy layer of foam. A flat white is a similar size but has a thin layer of velvety microfoam and tastes more coffee-forward, often made with a double or ristretto shot. A latte is the largest and milkiest (around 240–350 ml) with only a thin layer of foam on top.
These three drinks contain the same two ingredients — espresso and steamed milk — so the differences can seem tiny. They come down to how much milk, how much foam and how big the cup is. Those three things change the taste and strength more than you'd expect.
At a glance
| Cappuccino | Flat white | Latte | |
|---|---|---|---|
| Typical size | 150–180 ml | 150–180 ml | 240–350 ml |
| Espresso | Single or double | Double (often ristretto) | Single or double |
| Milk texture | Airy, thick foam | Silky microfoam, thin layer | Silky, more liquid milk |
| Foam depth | ~1.5–2 cm | ~0.5 cm | ~1 cm |
| Coffee taste | Strong, balanced by foam | Strongest of the three | Mildest, creamiest |
| Classic serving | Cup | Small cup or glass | Large cup or glass |
Café chains often serve larger sizes of all three, which blurs the lines. These are the traditional proportions.
Cappuccino
The classic cappuccino is often described as equal thirds: espresso, steamed milk and foam. In practice, most modern cappuccinos have more milk than that, but the defining feature remains a thick, dry-ish layer of foam on top. It feels light and airy, and the coffee taste stays clear because there isn't much liquid milk.
At home: 40–60 ml of strong coffee + 60 ml (2 oz) warm milk + a generous spoonful of foam. The jar-and-microwave method in our frothing guide makes good cappuccino foam.
Flat white
The flat white rose to fame in Australian and New Zealand cafés. It's about the same size as a cappuccino but uses finely textured "microfoam" — milk with tiny bubbles that make it glossy and velvety — poured so that only a thin layer sits on top. Many cafés use a double shot, sometimes as ristretto (a shorter, sweeter shot — see ristretto vs lungo).
Because there's less milk volume and little foam, the coffee flavor is the most pronounced of the three.
At home: 50–60 ml of strong coffee (moka pot or concentrated AeroPress) + 100–120 ml milk frothed silky in a French press, poured so only a thin layer of foam sits on top.
Latte
The latte (from caffè latte, "milk coffee") is the biggest and gentlest. Espresso is topped with plenty of steamed milk and a thin layer of foam, about a centimeter. The coffee becomes a background note in a creamy drink — which is why lattes are the base for flavored syrups.
At home: 50–60 ml of strong coffee + 200–250 ml steamed milk with a thin foam layer.
Strength compared
How strong the drink tastes depends mainly on the ratio of coffee to milk:
| Drink | Approx. coffee : milk (by volume) | Tastes |
|---|---|---|
| Macchiato | 1 : a dollop | Very strong |
| Cortado | 1 : 1 | Strong |
| Flat white | 1 : 2–3 | Coffee-forward |
| Cappuccino | 1 : 2–3 (much as foam) | Balanced |
| Latte | 1 : 4–6 | Mild |
See cortado vs Gibraltar vs piccolo for the smaller drinks.
Caffeine
Caffeine depends on the number of espresso shots, not the amount of milk. A latte and a flat white made with a double shot contain about the same caffeine — the latte just tastes milder. Check yours with the caffeine calculator.
Which should you order?

| A big, mild, creamy drink | Latte |
| Something sweet and flavored | Latte with syrup |
Frequently asked questions
Which is stronger, a flat white or a latte?
A flat white tastes stronger because it has less milk relative to the coffee, even if the caffeine is similar.
Does a cappuccino have more foam than a latte?
Yes. A cappuccino has a thick foam layer; a latte has only a thin one.
Can I make these without an espresso machine?
Yes — use strong coffee from a moka pot or AeroPress and froth milk with a French press or handheld frother.
Which has the least calories?
The smallest drink with the least milk — usually a flat white or cappuccino — unless you choose a smaller latte or a lower-fat milk.
- Espresso tonic — Scandinavia
- Freddo espresso — Greece
- Greek frappé — Thessaloniki, Greece
- Irish coffee — Foynes, Ireland
