Latte vs Cappuccino vs Flat White: Differences Explained
A latte, a cappuccino and a flat white all start with espresso and steamed milk; what separates them is proportion and foam. The cappuccino (150 to 180 ml) pairs roughly 25 ml of espresso with 100 ml of milk under a thick 1 to 1.5 cm foam cap. The latte (240 to 360 ml) drowns the same shot in two to three times more milk with about 1 cm of foam. The flat white (160 to 200 ml) is the strongest of the three: a double espresso, often pulled as a ristretto, under a thin 0.5 cm layer of velvety microfoam.
- Cappuccino: 25 ml espresso + 100 ml steamed milk in a 150 to 160 ml cup (INEI definition), served up to 180 ml in practice, airy 1 to 1.5 cm foam
- Latte: one or two shots + 200 to 300 ml milk, 240 to 360 ml serving, about 1 cm of foam
- Flat white: double espresso (about 50 ml, often ristretto) + about 130 ml milk, 160 to 200 ml cup, 0.5 cm microfoam
- Caffeine: about 63 mg per single shot, about 126 mg for the flat white's double
- Origins: Italy for latte and cappuccino; the Antipodean café scene of the 1980s for the flat white, whose name was already in circulation in England
The three drinks, defined
Stand at any specialty counter long enough and you will hear the same hesitation: a customer scanning three names that sound interchangeable and cost nearly the same. They are not interchangeable. The latte, the cappuccino and the flat white are three deliberate answers to one question: how much milk does an espresso want, and in what texture? Here is each answer in turn.
The cappuccino is the codified classic. The Italian Espresso National Institute (INEI) pins it down to the millilitre: 25 ml of espresso plus 100 ml of cold milk steamed up to roughly 125 ml of volume at around 55 degrees Celsius, poured into a 150 to 160 ml porcelain cup. What the institute does not specify is foam depth. The airy, spoonable dome of 1 to 1.5 cm is trade practice, as is the rule of thirds (one third espresso, one third hot milk, one third foam), a handy visual shorthand with no normative status. Our step-by-step guide on how to make a cappuccino covers the full technique.
The latte, short for caffè latte, began as an Italian breakfast habit of coffee softened with plenty of milk, then was reshaped by American specialty culture into the tall, gentle drink we know: one or two shots of espresso under 200 to 300 ml of steamed milk, served in a 240 to 360 ml glass or cup with about 1 cm of foam. Its broad, calm surface made it the canvas on which modern latte art was painted, a craft we unpack in our milk foam and latte art guide.
The flat white is the youngest of the trio and carries a genuine diplomatic incident in its history. The drink as we know it emerged in the Antipodean café scene of the 1980s, and Australia and New Zealand have argued about parentage ever since: Sydney points to a printed mention in a May 1983 review of the café Miller's Treat and to Alan Preston's 1985 permanent menu at Moors Espresso Bar, while New Zealand counters with Auckland's café DKD and with Wellington's Bar Bodega, where a failed cappuccino in 1989 allegedly got served anyway under an apologetic new name. The name itself is older than either claim: it was in print in England by 1971 and spoken on screen in a British film of 1963. The modern recipe, at least, is settled: a double espresso of around 50 ml, frequently pulled as a ristretto, with about 130 ml of milk steamed into the thinnest possible microfoam.

Caffeine based on USDA data: roughly 63 to 64 mg per 30 ml espresso shot. Volumes vary between cafés.
How much milk does each of the three drinks actually carry?
Roughly 100 ml in a cappuccino, roughly 130 ml in a flat white, and 200 to 300 ml in a latte, which works out as ratios of about 1:2, 1:2 to 1:3, and 1:3 to 1:5. Read the ratios alone and the flat white looks close to the cappuccino; read the base as well and it is not, because it starts from a double shot, so the absolute weight of coffee in the cup doubles.
This is why the flat white tastes so much more like the coffee itself. A washed Kenyan with blackcurrant acidity will still announce itself through 130 ml of milk behind a double ristretto; pour the same beans into a 350 ml latte and the cup mostly tastes of warm milk with a coffee accent. Neither outcome is wrong. They are simply different contracts between bean and bottle.
How thick is the foam layer meant to be on each drink?
About 1 to 1.5 cm on a cappuccino, about 1 cm on a latte, about 0.5 cm on a flat white. Those three targets are what a barista is aiming at before anything else. The cappuccino cushion is airy and stable enough to hold a dusting of cocoa; latte foam is looser and folds into the milk as you drink; the flat white sits at the opposite extreme, with bubbles so fine they vanish, leaving milk with the sheen of wet paint that pours into sharp rosettas.
Those targets are not interchangeable, which is why the same jug cannot serve all three. Milk poured at cappuccino thickness into a flat white cup simply produces a small cappuccino. On the textures themselves, see our guide to fixing big bubbles in milk foam.
What cup does each drink belong in?
A warmed porcelain cup of 150 to 180 ml for the cappuccino, a handled ceramic cup of 160 to 200 ml for the flat white, and a 240 to 360 ml glass or bowl-shaped cup for the latte. Regional habit splits the middle one: Australian cafés lean towards the 200 ml end, New Zealand towards a smaller cup of around 175 ml, which is part of why the two countries describe the same drink slightly differently.
A practical rule for travellers: if your cappuccino arrives in a 300 ml mug, you have effectively been served a latte wearing a foam hat. Chains have inflated sizes across the board, but ratios do not lie, and neither does the first sip.
Does a bigger cup mean more caffeine?
No. Caffeine tracks the number of espresso shots, not the volume of milk poured over them. A 30 ml shot carries roughly 63 to 64 mg of caffeine according to USDA data, so a traditional single-shot cappuccino or latte lands around 63 mg whatever the cup, while the flat white's double base reaches about 126 mg in a vessel half the size of a large latte.
The complication is modern café practice: many shops pull doubles into large lattes by default, which levels the caffeine while leaving the flavour gap intact. For shot-by-shot numbers, see our dedicated comparison of caffeine in cappuccino vs latte.
Which drink fits the way you take your coffee?
One question settles it: do you want coffee, balance or milk? Flat white, cappuccino and latte answer in that order.
- You want to taste the beans: flat white. The double ristretto and whisper of microfoam keep the origin character in front.
- You want the classic balance: cappuccino. Coffee, milk and foam in near-equal parts, the Italian morning ritual.
- You want comfort and volume: latte. Gentle, milky and forgiving, the drink that pairs best with a long breakfast.
- You are watching caffeine: a single-shot cappuccino or latte (about 63 mg) over a flat white (about 126 mg).
- You are practising latte art: the latte gives you the widest canvas; the flat white demands the finest milk and rewards it.
Frequently asked questions
What is the difference between a latte, a cappuccino and a flat white?
All three combine espresso and steamed milk; the proportions and the foam set them apart. A cappuccino is small (150 to 180 ml): roughly 25 ml of espresso, 100 ml of steamed milk and a thick, airy foam cap of 1 to 1.5 cm. A latte is large (240 to 360 ml): the same espresso base under two to three times more milk, topped with about 1 cm of foam. A flat white sits in between in size (160 to 200 ml) but not in strength: it is built on a double espresso, often pulled as a ristretto, finished with a thin, velvety microfoam of about 0.5 cm.
Is a flat white stronger than a latte?
Yes, on both counts that matter. A classic flat white uses a double espresso (around 50 ml, about 126 mg of caffeine based on the USDA figure of roughly 63 to 64 mg per 30 ml shot) in a 160 to 200 ml cup, while a traditional latte uses a single shot (around 63 mg) in a 240 to 360 ml serving. The flat white therefore has more caffeine in total and a far higher coffee-to-milk concentration, which is why it tastes noticeably more intense. The caveat: many cafés now pull double shots in large lattes, which evens out the caffeine but not the intensity.
Who invented the flat white, Australia or New Zealand?
Both countries claim it and the dispute is unresolved. On the Australian side, a written reference to a flat white coffee appeared in a May 1983 review of the Sydney café Miller's Treat, and Alan Preston put the drink on his permanent menu at Moors Espresso Bar in Sydney in 1985. On the New Zealand side, claims come from Auckland's café DKD and from Wellington's Bar Bodega, where the drink is said to have emerged from a failed cappuccino in 1989. Neither claim covers the name itself, which was already in print in England by 1971. What is reasonably settled is that the drink in its current form took shape in the Antipodean café scene of the 1980s and reached the rest of Europe in the 2000s.
What is microfoam and why does the flat white depend on it?
Microfoam is steamed milk in which the air bubbles are so small they are invisible, giving the milk a glossy, paint-like texture. A flat white carries only about 0.5 cm of it, compared with about 1 cm of foam on a latte and 1 to 1.5 cm of airy foam on a cappuccino. Because the foam layer is so thin, the milk and the double espresso blend into one continuous, velvety body, which is the defining sensation of a well-made flat white and the reason baristas treat it as a test of steaming technique.
