Last Updated on September 21, 2023 by Timothy Byron Smith

Coffee lovers come in all preferences – from those who savor a small, slow sip to others who crave a generous gulp from a big mug. But one thing is universal: no one wants too little coffee in their cup. Keurig, known for its user-friendly coffee makers, has a range of cup sizes that can be a tad perplexing. Let’s unravel the mystery together!

Keurig coffee makers are typically single-serve machines, meaning they brew one cup of coffee at a time. To make it easy, Keurig cup sizes are measured in ounces. There are five Keurig oz sizes in total, although the actual size may vary depending on your Keurig model.

Join us as we demystify Keurig’s cup sizes!


What are the Keurig 5 Cup Sizes?

With a total of five Keurig cup sizes, the amount of coffee you get in each size differs. You can choose the various cup size options on the Keurig coffee machine quite easily. It will either be physical Keurig size buttons or a digital option on the display. But how many ounces in a Keurig cup do you get?

The ounces you get in the Keurig cup are basically the ounces of water dispensed from the water reservoir. So, the more water, the fuller the cup and, therefore, the thinner (weaker) the coffee. On the other hand, with less water, you get a shorter cup and thicker (stronger) coffee.

In any of the Keurig machines, you’ll get either three or five-size options. Here are the cup-size choices Keurig has to offer!

Four Ounces (4 oz):

The smallest cup size available in Keurig machines is four ounces. It is perfect for those who prefer a strong cup of coffee that hits you with caffeine. It’s also great for when you make espresso with a Keurig coffee maker. However, this size is not available in all Keurig machines.

Six Ounces (6 oz):

Keurig coffee maker cup sizes increase by an increment of two ounces. As such, this is the second smallest Keurig cup size. Six ounces is a strong enough coffee. However, if it is too strong for some, we suggest moving to the next cup size.

Eight Ounces (8 oz):

This third cup size by Keurig is the most commonly used by most coffee drinkers. Many consider it just the right balance between too strong and too weak coffee. As such, the eight-ounce size is available in all Keurig models.

Ten Ounces (10 oz):

This is another popular size of all the Keurig cup sizes. Therefore, it is also found in almost all Keurig coffee machine models. This is when the coffee starts to become weak. It’s great for those who want to enjoy their coffee without a strong hit.

Twelve Ounces  (12 oz):

The last and largest cup size offered by Keurig is the twelve ounces size. This actually means more water dispensed into the cup, so the coffee will be thinner and weaker. It is a rather uncommon size and is not found in many Keurig models.

  • Since the K Mini and K Mini Plus have a water reservoir capacity of 12 ounces, a refill will be required every time you brew a 6 to 12-ounce brew. This is important to remember. Often, an empty reservoir is a reason for Keurig lights blinking or flashing issues.
  • A lot of people struggle between the K-Slim vs K-Mini Keurig coffee maker. Cup size is an important comparable feature. And in this case, the K Mini definitely wins.
  • K-Duo and K-Duo Plus are also equipped to brew 6 to 12 ounces of drip coffee.
  • For cappuccino and latte lovers, K Cafe can brew a strong coffee of 2 oz for cappuccinos and lattes.


How to Select Between Keurig Cup Size Buttons?

Selecting the right cup size matters! However, the buttons to select a cup size in Keurig machines are not the same across all Keurig machines. Mostly, Keurig coffee makers have physical buttons on the top of the front part of the machine. These are labeled with numbers or icons to make choosing a bit easier for you.

So, for example, if you own the latest K-Supreme Plus model, it features five numbered buttons on the top of the machine. However, in the K-Elite model, the buttons have cup icons that grow by size to indicate the cup size. And there’s another third way of displaying the size options.

The K Mini and the K Mini Plus both use the quantity of water used to estimate the cup size. So, the cup size options range from 6 to 12 ounces.

How Much Coffee is in a Keurig K-Cup Pod?

Although the K-cup flavors are abundant, the K-cup sizes are quite limited. In fact, Keurigs only have one K-cup size and they all contain similar amounts of coffee. Typically, Keurig K-cup pods are known to have between 10 to 13 ounces of coffee. This makes for a total of two tablespoons.

How Many Ounces of Coffee Does Keurig K-cup Make?

Typically, sticking to 8 ounces is considered ideal and makes for an adequately large cup of coffee. However, if 8 ounces is too weak, you can opt for 6 ounces. Conversely, if 8 ounces is too strong for you, go for 10 ounces.

It all really comes down to how strong or weak you prefer your coffee. So, if in an attempt to get more coffee, you’re brewing 12 ounces, beware that it will turn out to be pretty weak. That’s because you’re using a single K-cup for two 6-ounce drinks.

You can use K-cups for as much as a 7-inch travel mug! Just remember to use the right number of K-cups so it doesn’t turn out too weak and watery.
