Keurig Cup Sizes Explained (Everything you Wanna Know!)

Earlier when the Keurig coffee makers were invented in 1998 there was only one cup size available and that was a standard 8 oz serving size.

As time evolves, coffee drinkers’ preferences have changed as well. Some prefer to have big 10 or 12-ounce mugs of coffee, while others enjoy strong and dense 4 or 6 ounce shots of coffee.

Fortunately, Keurig has always strived to meet all expectations of coffee lovers beyond providing convenience.

Almost all Keurig models now have at least three cup sizes, and some advanced models offer five cup sizes, as well as strength control settings so that you can adjust the strength of the coffee according to your taste.

The purpose of this article is to list all the Keurig models and their cup sizes as well as to explain how the change in coffee size affects the strength of your beverage.

What are 5 Keurig Cups sizes

Keurig uses ounces as a unit of measurement to classify the size of the cup.

Keurig offers these 5 cups sizes

  • 4 oz (120 mL)
  • 6 oz (180 mL)
  • 8 oz (240 mL)
  • 10 oz (300 mL)
  • 12 oz (360 mL)

In general, The larger the cup size, the fuller the cup and the weaker the taste; the smaller the cup, the denser the shot and stronger the taste.

Keurig Cup sizes

Keurig models usually let you select the size of your brew with the push of a button. Some have buttons with numbers like 6oz, 8oz, etc., while others have figures of coffee mugs from small to large.

The Keurig Mini and Mini Plus, however, have a small single-serve water reservoir, you must fill the water reservoir every time; so you can pour any amount of water between 6 ounces and 12 ounces to brew your coffee.

Does Cup Size Affect the Strength of Coffee

Yes, cup size definitely affects the strength and intensity of the coffee. The amount of coffee in a k cup coffee pod remains the same whether you choose a large or small brew size. Therefore, the larger brew size will be weak and watery, while the smaller brew size will be strong and intense.

Need More Strength? Hit the strong Button

As a new feature on its advanced models, Keurig now offers a strong button so users can make a stronger cup of coffee.

We all know the basics of coffee more the extraction time stronger the cup of coffee (up to a point, though! Extra extraction may also make your coffee overly bitter)

Using the strong button slows down the brewing process by 30-40 seconds, which gives the water extra time to extract flavors from the coffee grounds in the K cup, resulting in a stronger cup of coffee.

Pod-based machines like Keurig are often accused of making watery or tasteless coffee (I Agree!), but new Keurig Supreme models feature multi-stream technology and a strong button that allows them to brew stronger coffee at least better than other single-serve pod machines.

What is the best Coffee size for Keurig?

You might be confused by the different brew sizes available on Keurig coffee makers and wondering what will produce the best-tasting coffee.

Let me explain with the help of simple maths.

K cup coffee pod contains around 9-12 grams of coffee (0.3-0.4 ounces)

According to the specialty coffee association, the perfect coffee-to-water ratio is 55 g/L ± 10.

That makes around 1 gram of coffee grounds for every 17-20 grams of water (1:17-19).

So according to that calculations, 9-12 grams of coffee in a K cup pod is only enough for 5 to 7 oz coffee.

That means 6 oz is the best Coffee size for Keurig Hands Down!

Anything above than that; 8 oz, 10 oz, or 12 will be weak and watery. The 8 oz brew size is somewhat acceptable, however, the 10 oz and 12 oz cup sizes are completely useless and tasteless. I’m not sure why Keurig has added these sizes to their models (maybe some boring coffee lovers use that).

Nevertheless, you have your Keurig and K cup pods you can test every brew size and select what suits you the best however according to my experience and the calculations 6 oz is the sweet spot.

How many cups can Keurig brew at a time?

Keurig is a single-serve coffee maker and is only suitable for brewing 1-3 cups of coffee at a time. Most Keurigs can brew 5 to 8 cups of coffee before needing to be refilled. But brewing more than 3 cups in a Keurig takes much time, so the convenience and quickness which are the unique selling points of Keurig go away!

Keurig is probably not the best choice for you if you have a large household and you frequently have guests over. In that case, you should look into a drip coffee maker that can brew pots of coffee.

Yeah! Keurig can be used to brew multiple cups at a time occasionally but the point I am making here is it will not be convenient.

What’s the tallest mug fits under the Keurig Spout

Well, it depends on what model of Keurig you have, but generally, a standard-sized 5-inch mug can fit under every Keurig machine.

Additionally, most Keurig models come with a removable drip tray that gives you an extra two inches so you can easily fit a travel mug up to 7 inches tall.

Which Keurig Model can brew both single-serve cups and coffee pots

Keurig typically offers single-serve coffee makers, but its K duo series allows for both pot and single-serve brewing.

Keurig duo plus is a highly versatile streamlined pod coffee maker that can brew both single-serve k-cup and up to 12 cups of the carafe and has a convenient multi-position water reservoir.

Which Keurig Model can make Cappuccino and Latte

Keurig K café is the only Keurig model that comes with a built-in milk frother and has the ability to brew concentrated, espresso-like shots used in lattes and cappuccinos.

Even though K café can prepare these heavenly milk-based drinks with the convenience of K cup pods and in a much more cost-effective way, the taste of the Cappuccino and Latte will not match that of some fancy coffee shops.

Final Thoughts on Keurig cup sizes

The reason Keurig has ruled over the coffee industry for a decade is that it understands the needs of its customers. From single-serve coffee makers to carafe machines such as Duo as well as Latte machines such as K Cafe, to offering different cup sizes, adjustable strength settings, and over-iced options, Keurig has never disappointed its customers.

Most Keurig models offer 3-cup sizes and some advanced models do offer 5-cup sizes. It is important to note that the flavors of coffee do get affected depending on what coffee size you select, so try them all to find the one that suits your taste.

As described in this article, a 5-7 oz cup size from Keurig can make a perfect coffee, so if you’re looking for a new one, make sure it has a 6 oz brew size (And a Strong Button Too!).
