How many ml is a standard coffee cup?

A standard coffee cup can vary in size, but generally holds between 150-200ml (5-7oz) of coffee. The exact ml will depend on the style of cup and intended use. In this article, we’ll explore the typical sizes of coffee cups and mugs, look at how many ml different cup styles hold, and provide a conclusive answer on the ml capacity of a standard coffee mug or cup.

Common Coffee Cup and Mug Sizes

Coffee cups and mugs come in a variety of shapes and sizes. Here are some of the most common:


An espresso cup is small, generally around 60-90ml (2-3oz). It is designed to hold a single shot of espresso.


A demitasse is a miniature coffee cup, holding approximately 90-120ml (3-4oz) of coffee. It is used to serve espresso-based coffee drinks like cappuccinos and lattes in smaller portions.


These glasses are slightly larger than a demitasse, holding around 120-180ml (4-6oz). They are used for cortados, gibraltars, and other small espresso drinks.


A cappuccino cup holds 150-180ml (5-6oz) of coffee, leaving room for foamed milk at the top.


A latte glass or bowl holds around 240-300ml (8-10oz) to accommodate several shots of espresso plus steamed milk.


A typical coffee mug holds around 340-400ml (12-14oz). Large and “super” mugs may hold up to 600ml (20oz).

Travel mug

Insulated travel mugs are available in many sizes, most commonly 360-480ml (12-16oz).

As you can see, cup sizes can vary greatly based on type and intended use. But most everyday coffee mugs hold between 300-400ml (10-14oz) of coffee.

Factors That Affect Cup Size

Several factors influence coffee cup sizes:

Type of coffee

The type of coffee beverage impacts cup size. An espresso shot requires just 60-90ml while a latte needs a wider cup or bowl to accommodate the steamed milk.

Cultural/geographic norms

Coffee cup norms differ around the world. The average cup in Australia/New Zealand holds 160ml. European cups average 125ml. American cups tend to be larger at 200ml or more.


Insulated cups like travel mugs often hold more since the insulation takes up some internal space.

Home vs commercial use

Commercial coffee shops often use smaller cups for espresso-based drinks. Home mugs tend to be larger for sipping over time.


Material impacts capacity. Thin glass/ceramic holds less than thick walled mugs. Handle size also alters internal cup volume.

So while cups vary, when someone refers to a “standard” coffee cup, they typically mean a home/office mug holding 300-400ml.

Typical Capacity of Coffee Cup Styles

Here are the typical capacities of some common coffee cup types:

Cup Type Average Capacity
Espresso 60-90ml
Demitasse 90-120ml
Cortado/Gibraltar 120-180ml
Cappuccino 150-180ml
Latte 240-300ml
Mug 340-400ml
Travel mug 360-480ml

As shown, the standard coffee mug holds between 340-400ml on average. More specific capacities by mug type are:

– Ceramic mugs – 340-400ml
– Glass mugs – 340-360ml
– Stoneware mugs – 360-400ml
– Stainless steel mugs – 360-420ml
– Insulated plastic travel mugs – 380-480ml

So while there is some variation among materials, most everyday coffee mugs hold between 350-400ml.

Standard Cup Sizes Based on Coffee Type

If we consider “standard” based on coffee drink type, typical capacities would be:

– Espresso – 60-90ml
– Americano – 180ml
– Macchiato – 90ml
– Cortado – 120ml
– Flat white – 160ml
– Cappuccino – 180ml
– Latte – 240-300ml
– Mocha – 300ml
– Regular drip brewed coffee – 340-400ml

The cup size matches the expected beverage volume. Espresso-based drinks use smaller cups while larger mugs accommodate drip coffee servings.

How Cup Size Impacts the Drinking Experience

The size of a coffee cup impacts the drinking experience:


A smaller cup like an espresso keeps the beverage hotter for longer compared to a large mug. The extra surface area of a big mug loses heat faster.

Balance of flavors

Cup size imparts flavor balance. An espresso’s strong taste needs just 60-90ml. More liquid can make it bitter and unbalanced.

Quantity consumed

Larger cups lead to greater consumption. We’re conditioned to finish a full cup/mug. So a 340ml mug leads to drinking more caffeine than a 150ml cup.

Accommodating additions

Some coffee drinks require extra room for milk foam or whipped cream. A cappuccino needs 150-180ml capacity to accommodate the foamed milk.

So cup size directly impacts factors like ideal serving temperature, flavor balance, consumption habits, and ability to hold added ingredients.

How to Estimate Cup Size

If you don’t know the ml capacity of a cup, here are some ways to estimate it:

Check manufacturer info

Many cups/mugs have size info on the bottom. This usually indicates capacity in ml or oz.

Measure with a measuring cup

Fill the coffee cup with water using a metric measuring cup to determine approximate ml capacity.

Read markings

Some cups have interior markings indicating capacity in ml or oz. Check for this indicator.

Estimate based on contents

You can get a rough idea of size based on how many cups of drip coffee or shots of espresso the mug holds.

Compare to standard sizes

Look at photos of standard espresso, cappuccino, and latte cups and visually compare capacities.

Use an app

Apps like “Measure” use augmented reality to digitally measure objects and provide ml/oz capacity.

Standard Cup Size FAQs

Here are answers to some frequently asked questions about standard coffee cup capacities:

What is the size of a standard coffee cup?

A standard coffee mug or cup holds between 300-400ml, or about 10-14oz. This capacity is ideal for regular coffee servings.

How many oz is a standard coffee mug?

A typical coffee mug holds around 10-14oz of coffee. More specifically, a standard mug is usually 12-14oz (350-400ml) in capacity.

What is the average size of a coffee cup?

The average coffee cup size is around 250-350ml (8-12oz). Small espresso cups may be 60-90ml while large mugs can hold up to 600ml (20oz). A standard mug is 300-400ml.

How many ml are in a regular coffee cup?

A regular sized coffee cup or mug typically contains between 300-400ml of liquid. This accommodates the average amount of coffee served in a mug or cup.

How many oz is a latte cup?

A standard latte cup holds around 8-10oz (240-300ml) to accommodate espresso and steamed milk. Larger sizes are sometimes used as well.

Converting Between ML and Ounces

Since cup sizes are often described in either milliliters or ounces, this conversion table helps translate between the two units:

Milliliters Ounces
30ml 1oz
59ml 2oz
89ml 3oz
118ml 4oz
148ml 5oz
177ml 6oz
207ml 7oz
236ml 8oz
266ml 9oz
295ml 10oz
325ml 11oz
354ml 12oz
384ml 13oz
413ml 14oz

So to convert milliliters to ounces, divide by 30. To convert ounces to ml, multiply by 30.

As a example, a standard 350ml coffee mug is equivalent to 350/30 = 11.7oz.

And a 12oz mug is 12*30 = 360ml.


In summary, while coffee cup sizes vary from tiny espresso cups to giant mugs, a “standard” everyday coffee cup or mug holds about 300-400ml, or 10-14oz. This capacity accommodates the average quantity of coffee served into an everyday drinking vessel. Smaller cups are used for espresso-based drinks which require less liquid, while large mugs hold more for sipping over time. But in general, 300-400ml (10-14oz) is considered a standard coffee cup size. When converting between milliliters and ounces, remember that 1oz = 30ml. So a standard 350ml mug would be 11.7oz. Understanding typical coffee cup sizes provides a useful reference for serving coffee drinks in properly sized vessels.
