Flat White vs Latte: Every Difference That Matters

By Coffee Ratio Calculator Guru · Updated January 2025 · 5 min read

A flat white is smaller, stronger, and has less foam than a latte. Use our milk to espresso ratio calculator to see the exact milk volumes for both. The difference comes down to three things: milk ratio, total volume, and foam texture.

The Milk Ratio

A latte uses approximately 3.5 parts steamed milk to 1 part espresso. A flat white uses approximately 2.5 parts milk to 1 part espresso. With the same double espresso base (60ml), this means a latte gets 210ml of milk while a flat white gets 150ml. The lower milk volume in a flat white allows the espresso flavour to come through more prominently, creating a more intense, less diluted experience despite both containing the same amount of coffee.

Foam and Milk Texture

Both drinks use microfoam — steamed milk with tiny, integrated bubbles rather than the stiff dry foam of a cappuccino. However, the flat white's microfoam is typically even more integrated and silky than a latte's, heated to 58–62°C rather than 62–65°C. The result is a thinner, more velvety milk texture that pours differently and creates a distinct mouthfeel. Many specialty cafés also use a ristretto base (1:1.5 ratio) for flat whites instead of a standard double, which adds sweetness and reduces the bitterness contrast with milk.

Size and Serving

A standard latte is served in an 8–12oz cup. A flat white is traditionally served in a 5–6oz ceramic cup. This size difference is significant: even with the same coffee dose, the smaller volume means more concentrated espresso flavour per sip. The flat white is closer to a cappuccino in intensity while maintaining the smooth, microfoam texture of a latte.
