The short answer
A flat white is a 5–6 oz drink built from a double ristretto shot and silky microfoam — no dry foam layer on top. A latte is 8–16 oz of espresso with much more steamed milk and a thin cap of airy foam. The flat white tastes stronger because the coffee-to-milk ratio is roughly 1:3, while a latte runs about 1:5 or higher.
If you want to taste the espresso, order a flat white. If you want a smooth, milky, easy-drinking cup, order a latte.
Size and ratio: the numbers
This is where the two drinks diverge most:
• Flat white: 5–6 oz total. Double ristretto (≈45 ml) + ≈100–130 ml steamed milk with microfoam throughout. Coffee-to-milk ratio roughly 1:3.
• Latte: 8–16 oz total. Single or double shot (≈30–60 ml) + 200–350 ml steamed milk with a thin foam cap. Coffee-to-milk ratio roughly 1:5 to 1:8.
The flat white’s smaller cup means every sip carries more coffee intensity, even though both drinks use a similar amount of espresso.
Espresso and milk texture
Most specialty cafés pull a ristretto (shorter, sweeter shot) for the flat white and a standard shot for the latte. The ristretto concentrates sweetness and cuts bitterness, which pairs well with the thin, glossy microfoam that defines a flat white.
A latte’s milk is steamed with a brief burst of air to create a light foam layer on top — enough for latte art but airier than a flat white’s texture. The result is a creamier, milder drink where milk is the star rather than the supporting act.
Caffeine and calories
Both drinks typically use a double shot, so caffeine is similar: roughly 126–130 mg from two shots of espresso. The calorie difference comes from milk volume:
• Flat white (whole milk, 6 oz): ≈110 calories.
• Latte (whole milk, 12 oz): ≈190–210 calories.
Switch to oat or skim milk and both numbers drop. Use the Caffeine Calculator to track your daily total.
When to order each
• Order a flat white if you like tasting espresso through the milk, want a smaller drink, or prefer a velvety-smooth texture without dry foam.
• Order a latte if you want a large, easy-drinking cup, like your coffee mild and creamy, or plan to add syrup or flavoring — the extra milk carries sweetness well.
Neither is "better." They are different balances of the same two ingredients. Once you see drinks as ratios, the whole menu makes sense — and you can explore more comparisons like cortado vs macchiato or latte vs cappuccino.
