Coffee Holli Top Pick

Once upon a time:

Keurig only had the 8 Oz cup size. This was hardly enough to satisfy customers. Some people want their small, strong cup of coffee, while others don’t mind a filled mug.

But Keurig listened to their customers and created more cup options.


The company offers customers five different cup sizes to choose from. In this blog post, we’ll be exploring these cup sizes and much more.

Keurig Cup Size Guide

As already mentioned, Keurig has five cup sizes. These sizes are:

  • 4 Ounces: The smallest Keurig cup, the 4 Oz cup size is ideal for making that small, very strong hot cup of coffee. They’re especially ideal for espresso but can also be used for cappuccino.
  • 6 Ounces: The 6 Oz cup size is also good for making a strong hot coffee like espresso, but is best for cappuccino. But then, you’ll get 2 ounces extra of coffee.
  • 8 Ounces: This is Keurig’s most popular cup size as it’s the original Keurig size and is also considered the standard cup size. It is not too big or too strong, thus a good option if you want a mild-tasting coffee. From hot coffee to iced coffee, latte, and cappuccino You can also use this cup size for both hot and iced coffee.
  • 10 Ounces: The 10 Oz cup size is a bit bigger than the popular 8 Oz cup. It is recommended for latte, iced coffee lovers and those who want that extra caffeine goodness.
  • 12 Ounces: The 12 Oz cup size is the biggest Keurig cup size available. If you like to sip your coffee for a longer time, the 12 Oz cup is for you. Also, because it has a lot of space, it is ideal for iced coffee and other coffees that require a lot of toppings. However, you’re likely to get weak coffee.
Keurig Insert K-Cup

For most Keurig machines, all you have to do is press the button of the corresponding cup size you want to brew. Some machines have the name of the size on the button, while others have a picture of the cup size.


Small coffee makers like the K-Mini and K-Mini Plus don’t have buttons. They, instead, automatically choose the coffee size based on how much water is in the reservoir.

2 Tips for Choosing a Cup Size According to CoffeeHolli’s Baristas

The following are two important tips from our professional baristas to help you choose the ideal coffee cup size:

Consider the Amount of Coffee You Need

First and foremost:

The cup size you choose should match the amount of coffee you need. You don’t want to go for a 4 Oz cup size when you’re looking to energize yourself with some caffeine goodness.

You’ll most likely end up being unsatisfied and wanting more.

Consider the Type of Coffee You Want

In other words:

The type of coffee you prefer should determine how big the cup is.

For example, if you like iced coffee, you need a cup with sufficient space for the ice and other garnishes. Therefore, the 12 Oz cups should be ideal.

Also, if you like lattes, you need at least a 10 Oz cup for the best experience. Using smaller cup sizes for such drinks will likely overflow your cup.


If you’re into espresso, you need much smaller cup sizes like 4 Oz. Using oversized cups for espresso could cause the crema to disappear quickly.

It also means that your espresso may get cold much faster and you know espresso is best taken hot.


So far, we’ve been able to establish the following about Keurig cup sizes:

  • Keurig has five different cup sizes – 4, 6, 8, 10, and 12 Oz
  • 6, 8, 10, and 12 Oz are the most available cup sizes
  • Only three Keurig machines have all five cup sizes
  • The amount and type of coffee you need should determine the cup size you choose
  • Small cups like the 4 Oz and 6 Oz are suitable for espresso and cappuccino
  • Large cups like the 10 Oz and 12 Oz are ideal for iced coffee and latte

Now that you know the Keurig cup sizes, why don’t you try out different cup sizes to know which ones suit your coffee preferences.

Which Cup Size Should I Use for My Espresso?

The travel mugs come in 12 and 14 Oz cups, meaning they’re ideal for coffees that need ample space like iced coffee, and latte.

Which Keurig Brewers Have the Most Cup Sizes?

The three brewers with the most cup sizes are K-Elite, K-Supreme Plus, and K-Supreme Plus Smart. They all have the five available cup sizes.
