Latte and cappuccino are both espresso drinks with steamed milk, but the difference comes down to three things: how much milk, how much foam, and the final size of the cup. A traditional cappuccino follows a 1:1:1 ratio, equal parts espresso, steamed milk, and foam, served in a small 5 to 6 oz cup. A latte is bigger, usually 8 to 12 oz, built with 3 to 5 parts milk for every part espresso and only a thin layer of foam on top.
Latte vs Cappuccino: Side-by-Side Comparison
Use the table below to decide which drink fits your taste and order quickly at any café.
| Attribute | Cappuccino | Latte |
| Espresso to milk ratio | 1:1:1 (espresso, steamed milk, foam) | 1:3 to 1:5 espresso to milk |
| Total size | 150 to 180 ml (5 to 6 oz) | 240 to 350 ml (8 to 12 oz) |
| Foam layer | Thick, about 10 to 15 mm | Thin, about 5 to 7 mm |
| Taste | Strong, espresso-forward | Mild, creamy, milk-forward |
| Typical cup | Small pre-heated ceramic cup | Wide ceramic cup or tall glass |
Latte means more milk, less foam. Cappuccino means less milk, more foam. That single line settles most of the confusion between the two drinks.
What Is a Cappuccino?
The Istituto Nazionale Espresso Italiano (INEI) defines its Certified Italian Cappuccino as 25 ml of certified espresso combined with 100 ml of fresh milk, steamed until it reaches roughly 125 ml total volume. The result should show a dense, velvety cream with micro-bubbles invisible to the naked eye, plus a white center ringed by a border of espresso crema.
The barista aerates the milk longer while steaming it, which creates those micro-bubbles and a thick, structured foam cap. That foam layer also insulates the drink, so a well-made cappuccino holds its heat longer than it looks like it should.
Two common variations exist. A dry cappuccino cuts the liquid milk and piles on extra foam, while a wet cappuccino adds more steamed milk and leans closer to a small latte in feel.
What Is a Latte?
“Latte” is simply the Italian word for milk, and that name tells you exactly what the drink is: milk-forward. According to James Hoffmann in The World Atlas of Coffee (2018), a caffè latte runs 8 to 12 oz, holds one or two shots of espresso, and finishes with milk that is only slightly aerated into a thin microfoam layer around 5 mm deep.
That light aeration is what makes lattes so smooth. The wet, silky microfoam blends straight into the espresso crema, which is also why the latte is the standard canvas for latte art.
The large milk volume absorbs added flavors without drowning them, which is why vanilla, caramel, and hazelnut syrups show up on lattes far more often than on cappuccinos. Iced versions work the same way, espresso poured over cold milk and ice, a format that traditional cappuccinos rarely use because they depend on warm foam.
If you make these at home, a capable machine makes both drinks easier to pull off. The Breville Barista Express espresso machine with its built-in steam wand covers both styles, and a stainless steel milk steaming pitcher gives you better control over foam texture than the carafes some machines include.
Taste and Texture: Which One Should You Order?
Pick the latte if you want creamy, mild, and smooth, because all that milk softens the espresso’s bitterness and brings out dairy sweetness. Pick the cappuccino if you want a stronger coffee bite with an airy, foamier mouthfeel in a smaller cup.
The numbers behind that choice are simple to picture. When both drinks start from a standard double shot of espresso, a smaller cappuccino dilutes that shot far less than a larger latte does, so each sip of cappuccino carries more coffee flavor per ounce. You can explore that contrast further in our breakdown of which drink actually tastes stronger.
Caffeine content is usually identical between the two when each uses the same number of espresso shots, since the milk changes flavor and body, not caffeine. We cover the details in our comparison of caffeine levels in lattes versus cappuccinos.
Ratios, Sizes, and Why Recipes Vary
The Specialty Coffee Association’s World Barista Championship rules describe modern milk beverages as espresso plus steamed milk with smooth, fully integrated microfoam, served immediately drinkable, with a total volume not exceeding 240 ml (8 oz). That standard reflects how specialty shops now blend milk and espresso into one harmonious drink rather than distinct layers.
But here is the honest caveat: no recipe is fixed across the industry. An Italian café may serve a compact INEI-standard cappuccino, while an American chain serves a 12 oz latte-style cappuccino from a much larger cup, and both are “correct” where they are made. Chain sizes especially drift upward, so the numbers above describe the traditional specialty standard, not a legal limit.
Nutrition follows the milk, too. Since a latte simply carries more milk, it usually carries more calories, a comparison we map out in our guide to calorie differences between these two drinks.
Home baristas can convert one drink into the other from a latte baseline: cut the milk volume by about half, steam with a couple extra seconds of aeration for thicker foam, and serve in a smaller cup. That single adjustment moves you from latte territory to cappuccino territory without touching your espresso at all, which is worth pondering the next time someone insists the drinks are totally different beasts.
Quick Answers to Common Questions
Do both drinks use espresso? Yes, both start from a single or double shot, typically a 36 g liquid yield double in modern cafés.
Which has more milk? The latte, by a wide margin, usually 200 to 300 ml of steamed milk.
Which is foamier? The cappuccino, with its dense 10 to 15 mm foam layer versus the latte’s thin veil.
Which is bigger? The latte, at 8 to 12 oz versus the cappuccino’s 5 to 6 oz traditional serving.
Looking beyond the classic pair, the latte family branches further. Our article on cold versus hot latte preparation explains how the format changes the drink, and decaf options for latte drinkers keeps the same comparison going for anyone cutting caffeine.
For reference copies of technique, Hoffmann’s The World Atlas of Coffee remains a solid desk companion for ratios and milk physics.
The Short Version
A cappuccino is a small, 5 to 6 oz espresso-forward drink split into thirds, with a thick foam cap and a strong coffee presence. A latte is a larger, 8 to 12 oz milk-heavy drink with a thin microfoam layer and a milder, creamier taste.
Next time you order, match the drink to the mood rather than guessing: bold and compact means cappuccino, smooth and large means latte. Both run on the same espresso, so the milk does all the deciding.
