Two espresso drinks with steamed milk, served in cups of different sizes. At first glance, a flat white and a latte look almost identical. But for coffee drinkers who care about strength and texture, the difference is meaningful.
Here’s exactly how they compare.
The Short Answer
| Flat White | Latte | |
|---|---|---|
| Cup size | 5–6 oz | 8–12 oz |
| Espresso | 2 shots (often ristretto) | 2 shots (standard) |
| Milk | ~4 oz | ~6–10 oz |
| Foam layer | Very thin (1–2 mm) | Thin (3–5 mm) |
| Strength | Stronger, more espresso-forward | Milder, milkier |
| Origin | Australia/New Zealand | Italy |
The flat white packs the same amount of espresso into a smaller cup, so the coffee flavor dominates. The latte is a more diluted, mellow experience.
What Is a Flat White?
A flat white is a small espresso drink with steamed milk and a very thin layer of microfoam. It originated in Australia and New Zealand in the 1980s (both countries claim credit), where café culture demanded a stronger alternative to the Italian cappuccino.
The defining characteristics:
- Small cup: 5–6 oz is traditional. Some cafés go up to 6.5 oz, but if you see a “flat white” in a 10 oz cup, someone’s taking liberties.
- High espresso ratio: With the same 2 shots you’d put in a much larger latte, the espresso flavor is intense.
- Ristretto base (often): Many cafés pull a ristretto shot for flat whites — a shorter extraction that’s sweeter, less bitter, and more concentrated. This is optional at home but makes a noticeable difference.
- Thin, velvety microfoam: The foam is stretched less than a cappuccino or even a latte. You want just enough air to create glossy, silky milk — not a distinct foam layer on top.
The result is a drink that tastes unmistakably of espresso, balanced by creamy milk rather than dominated by it.
What Is a Latte?
A latte (caffè latte in Italian, meaning “milk coffee”) is steamed milk topped with espresso, served in a larger cup. It’s the most popular espresso-based drink in most Western cafés.
The defining characteristics:
- Larger cup: Standard lattes are 8–12 oz, giving the milk more volume relative to the same espresso base.
- Creamy, mild flavor: The higher milk-to-espresso ratio makes lattes noticeably sweeter and less coffee-intense than flat whites.
- Thin microfoam layer: A latte still uses microfoam (not dry foam), but the layer is slightly thicker than a flat white — typically 3–5 mm.
- Customizable base: Because the milk flavor is so present, lattes work well with flavored syrups (vanilla, caramel, hazelnut) in a way that flat whites don’t — the syrup doesn’t overpower the espresso.

The Foam Difference
Both drinks use microfoam — steamed milk with very fine air bubbles incorporated throughout, creating a smooth, glossy texture. But the amount differs:
Flat white foam: Almost invisible as a separate layer. The goal is milk that’s been transformed into a uniform, velvety texture throughout — not a foam cap on top. When you drink a flat white, you taste milk and espresso together from the first sip.
Latte foam: A slightly more defined layer sits on top, though it should still be silky, not fluffy. A latte with dry or airy foam is poorly made — the microfoam should pour as a continuous stream with the steamed milk, creating that characteristic latte art surface.
Neither drink is a cappuccino. A cappuccino has a thick, intentional foam layer that makes up roughly a third of the drink.
The Espresso Difference: Ristretto vs Standard Shots
In many specialty cafés, flat whites are made with ristretto shots — espresso pulled with less water (roughly 1:1 or 1:1.5 ratio instead of the standard 1:2).
Ristretto shots are:
- Sweeter and less bitter
- More concentrated in flavor
- Less astringent
For a flat white served in a small cup, this sweeter shot complements the lower volume of milk. You still get a strong coffee hit, but without the sharper edges that a standard espresso shot can bring.
Lattes are almost always made with standard espresso shots. The extra milk already softens any bitterness, making ristretto less necessary.
If you’re making flat whites at home and want to experiment, try pulling your shot to a 1:1.5 ratio (e.g., 18g in, 27g out) instead of the standard 1:2 (36g out). The difference is noticeable.
How to Make a Flat White at Home
You need an espresso machine with a steam wand. The technique is the same as a latte — just scaled down.
Equipment:
- Espresso machine with steam wand
- 5–6 oz cup (a small ceramic cup works well)
- Milk frothing pitcher (12 oz is ideal for this size)
Method:
Prepare your espresso. Pull a double shot (or ristretto) directly into your 5–6 oz cup. Start the pour now — you want to add milk while the espresso is still hot and fresh.
Steam the milk. Use about 4 oz of cold milk. Position the steam wand tip just below the surface and keep the aeration phase very short — a second or two, not five. The goal is to heat the milk while incorporating minimal air. Target temperature: 140–150°F (60–65°C). The milk should be glossy and move as a single mass in the pitcher.
Pour immediately. Hold the pitcher close to the cup (about 1 inch above) and pour steadily. You want the milk to integrate with the espresso rather than sitting on top.
The finished drink should have little to no visible foam layer. If you see a distinct cap of foam, you’ve aerated too much — dial back the steaming time next round.

How to Make a Latte at Home
The process is nearly identical to the flat white, just with more milk and a larger cup.
Equipment:
- Espresso machine with steam wand
- 8–12 oz cup
- Milk frothing pitcher (20 oz gives you more control)
Method:
Pull a double shot into your cup.
Steam 6–8 oz of milk. Aerate slightly more than for a flat white — a few seconds to incorporate enough air for that thin microfoam layer. Target 140–150°F.
Pour from slightly higher (1–2 inches), guiding the milk stream to mix with the espresso first, then tipping the pitcher to release the foam at the end for latte art if you’re attempting it.
The result is a larger, milder drink with a visible but thin foam surface.
Which One Should You Order (or Make)?
Choose a flat white if:
- You want a stronger espresso flavor
- You prefer smaller, more concentrated drinks
- You find lattes too mild or milky
- You’re cutting down on dairy without cutting espresso
Choose a latte if:
- You prefer a milder, creamier coffee experience
- You like adding flavor syrups
- You’re newer to espresso and building up your palate
- You want a longer-lasting warm drink
How They Compare to Other Milk Drinks
| Drink | Cup Size | Foam Type | Espresso Ratio |

| Espresso macchiato | 2–3 oz | Dash of foam | Very high |
| Flat white | 5–6 oz | Very thin microfoam | High |
| Cappuccino | 5–6 oz | Thick, dense foam | Medium |
| Latte | 8–12 oz | Thin microfoam | Low-medium |
| Cortado | 3–4 oz | Minimal foam | High |

Common Questions
Does Starbucks make a flat white correctly?
Starbucks uses ristretto shots and serves their flat white in a smaller cup (12 oz Tall, which is still larger than the traditional 5–6 oz). It’s closer to a flat white than a latte, but not truly traditional. If you order one expecting an Australian café flat white, you’ll get a milder version.
Can you order a flat white in a larger size?
You can, but the drink stops being a flat white once the milk-to-espresso ratio changes significantly. If you add an extra shot and scale up to a larger cup while keeping the espresso proportion high, you’re closer to a large strong latte.
Is a flat white stronger than a cappuccino?
They’re similar in size, but the flat white typically tastes stronger because more of the cup volume is liquid milk rather than foam. Cappuccino foam adds volume without adding much sweetness or creaminess.
