A flat white is a 5–6 oz espresso drink with velvety, fully integrated microfoam and a stronger coffee-to-milk ratio. A latte is 8–12 oz, more milk-forward, and creamier. Both use espresso and steamed whole milk — the difference is size, milk volume, and foam texture.
If you want a stronger, more concentrated espresso experience in a smaller cup: flat white. If you want a gentler, milkier drink: latte.

What Is a Flat White?
A flat white is a small, concentrated espresso drink that originated in Australia or New Zealand (the two countries still argue about it). The name refers to the “flat” microfoam top — as opposed to the taller, stiff foam of a cappuccino.
Classic flat white construction:
- 2 shots of espresso (often ristretto — a shorter, more concentrated shot)
- ~3 oz of steamed whole milk
- A very thin layer of velvety microfoam, often poured with latte art
The foam in a flat white is fully integrated into the milk — not sitting on top, not dry. It pours together as one smooth liquid. At 5–6 oz total, the espresso is the dominant flavor even through the milk.
What Is a Latte?
A latte (full name: caffè latte, Italian for “milk coffee”) is the most popular espresso drink in most Western cafés. It’s designed to make espresso accessible — the larger volume of steamed milk softens the bitterness and extends the drink.
Classic latte construction:
- 1–2 shots of espresso
- 5–7 oz of steamed whole milk
- A thin layer of microfoam on top (thin enough for latte art, but not stiff or dry)
A latte at 10 oz has roughly the same amount of espresso as a 6 oz flat white — but the extra milk dilutes the flavor and makes it noticeably creamier and milder.
The Key Difference: Milk Ratio
Everything comes down to how much milk is in the cup relative to espresso.
Flat white: ~2:1 ratio (milk:espresso). Two shots in 5–6 oz means the espresso is prominent in every sip.
Latte: ~4:1 to 6:1 ratio (milk:espresso). The same two shots in a 10–12 oz latte are softened significantly by the extra milk.
This ratio difference is why flat whites taste “stronger” despite often using the same number of shots. You’re drinking the espresso with less dilution.
Foam Texture: Very Similar, Subtly Different
Both flat whites and lattes use microfoam — smooth, velvety milk where the bubbles are too small to see. Neither uses stiff cappuccino-style foam.
The difference is subtle:
- Flat white foam is extremely thin — barely a layer. The microfoam is fully incorporated into the milk, not floating on top.
- Latte foam is slightly more pronounced — a small, visible foam layer that floats above the steamed milk. Still thin enough for latte art.
In practice, a skilled barista makes both the same way. The “flatness” of a flat white refers to how little foam protrudes above the rim of the cup, compared to a cappuccino — not a comparison to a latte.
Flat White vs Latte: Espresso Strength
Many cafés serve flat whites with ristretto shots — espresso pulled with less water, creating a more concentrated, sweeter shot with lower bitterness. This is especially common in Australian-style cafés.
A ristretto flat white in 5 oz is extremely intense. A standard latte with one shot in 10 oz is very mild.
If your café asks “ristretto or standard shots?” when you order a flat white — that’s the most significant variable in how it will taste.
How to Choose
Order a flat white if you:
- Want to actually taste the espresso
- Prefer smaller drinks
- Like milk in coffee but don’t want it to dominate
- Are drinking specialty or single-origin espresso worth tasting
Order a latte if you:
- Prefer a milder, creamier coffee experience
- Like a larger, longer drink
- Are adding flavored syrups (the extra milk volume absorbs them better)
- Are new to espresso drinks
How to Make a Flat White at Home
- Pull two shots of espresso into a 5–6 oz cup or glass
- Steam about 4 oz of cold whole milk — aim for very fine, glossy microfoam with minimal air (about 1–2 seconds of stretching only)
- Pour immediately — integrate the foam fully into the milk as you pour, keeping the layer extremely thin
- Target total volume: 5–6 oz finished drink
The hardest part is the milk texture: too much air and you get a cappuccino-style foam top. The goal is silk, not fluff.

Common Questions
Is a flat white just a small latte? Not exactly. While both use microfoam and espresso, a flat white uses a higher espresso-to-milk ratio and is deliberately smaller. Many cafés also use ristretto shots in flat whites, which adds sweetness and concentration not found in a standard latte.
Is a flat white stronger than a latte? It tastes stronger because the milk-to-espresso ratio is lower — you’re tasting more espresso per sip. If both are made with two standard shots, the total caffeine is the same.
Which has more caffeine — flat white or latte? Usually the same, since both typically use 2 shots of espresso. However, some cafés use 3 shots for flat whites (especially if ristretto), which would make the flat white higher in caffeine.
Why does a flat white cost more than a latte? Some cafés charge more for flat whites because they use extra shots or ristretto shots (which require more espresso grounds). It depends entirely on the café.
