Keurig Slim Vs Mini: Which One Is More Compact?

Keurig coffee maker, or Keurig coffee machine, has become a popular household name in the world of coffee making, with a range of products targeting different consumer preferences. 

Two notable models in their lineup are the Keurig K Slim and Keurig K Mini.

Both of these models aim to offer a compact brewing process, catering to those with limited countertop space or seeking convenience without compromising on the quality of their coffee.

The main difference is that the Keurig Slim has a 46-ounce removable water reservoir, making it convenient for brewing multiple cups without frequent refills. 

On the other hand, the K Mini models only holds enough water for a single cup of coffee, between 6 and 12 ounces. 

While both Keurig models provide a space-saving coffee brewing solution, their distinct features cater to different user needs and preferences.

When deciding between the Keurig Slim and Mini, it’s essential to consider factors such as water capacity, brewing options, and energy-saving features. 

With this side-by-side comparison, potential buyers can make an informed decision on which compact Keurig coffee machines best fits their coffee-drinking habits and preferences.

Both the Keurig Slim coffee maker and Keurig K-Mini coffee maker have a compact and sleek design.

They are narrow and space-saving machines, with the K-Slim measuring 4.76 inches in width and the K-Mini at 4 inches wide, making them suitable for limited spaces in kitchens and offices.

They are a small coffee maker that features a new innovative design called multi-stream technology which helps to extract full flavor and aroma from K-Cup pods whenever you brew your coffee.

Single-Serve Brewing

The Keurig Slim and Mini models are both considered a single-serve coffee maker that focus on brewing one cup of coffee at a time. 

Regardless of the water reservoir size or the specific model, users can enjoy single servings of their favorite coffee with these machines.

A single user can use these two smaller Keurig models a single time to make their cup of coffee for the day.

K-Cup Compatibility

For easy brewing, both the K-Slim and K-Mini are compatible with the Keurig machine standard K-Cup coffee pods. 

This means that users have access to a wide range of coffee flavors and brands with these machines, as well as the option to use reusable K-Cup filters for using their own coffee grounds.

Removable Drip Tray

Both the Keurig K-Slim and K-Mini coffee makers come with a removable water tank. 

The placement of the water reservoir is different for each model. You can find the Keurig Slim’s water tank on its back while the Mini’s is on the top of the machine.

It is important to note that the Keurig K-Slim has some advanced features like a multi-cup reservoir and fast brew time. 

This allows users to easily clean the machines after use and helps accommodate different cup sizes, including travel-sized mugs, a larger cup of coffee, coffee cups and taller travel mugs, when the drip tray is removed.

Some of the key similarities between the Keurig K-Slim and K-Mini models include their compact design, single-serve brewing capabilities, K-Cup compatibility, and removable drip tray.

Key Differences


The K-Mini and K-Slim have different dimensions that may affect a user’s choice based on the available counter space in their kitchen. 

The K-Mini has a width of 4.5 inches, making it suitable for tight spaces, while the K-Slim has a width of 4.8 inches. 

The K-Slim is slightly taller (12.1 inches) than the K-Mini (11.3 inches), providing a more substantial water reservoir. This means that the K-mini has a small water reservoir.

Water Reservoir Capacity

The water reservoir capacity is a significant difference between the two models. 

The K-Mini has a smaller water reservoir of a 12-ounce capacity, which holds enough water to brew between 6 and 12 ounces of coffee at a time. 

In contrast, the K-Slim has a more generous 46-ounce water reservoir, allowing users to brew a larger amount of coffee. It is possible to brew multiple cups without constant refilling.

Brew Sizes

Both machines offer different preset brew sizes and different brew sizes:

  • K-Mini: Brews one cup at a time using the exact amount of water placed in the reservoir (6-12 ounces).
  • K-Slim: Offers 3 brewing sizes (8, 10, or 12 ounces), depending on the user’s preference.

Remember that a large cup size will produce less intense coffee. This means that a small size, or smaller size cup, will produce strong coffee for days when you want to drink a strong cup of coffee.


Another distinction between the two models is their weight. 

The K-Mini is lighter, weighing only 4.6 pounds, making it more portable and easier to move around the kitchen. 

On the other hand, the K-Slim is slightly heavier, weighing 6.4 pounds, due to its larger water reservoir.

Color Options

The K-Mini and K-Slim also come in different color options:

  • K-Mini: Matte Black, Oasis (blue-green), Studio Gray, and Dusty Rose.
  • K-Slim: Black, Gray, and White.

These color choices allow users to select a machine that matches their kitchen design and personal style preferences. 


The K-Mini and K-Slim have various features that make brewing coffee simple. 

Both models offer a single serve cup function for quickly making small amounts of coffee, as well as auto shutoff and cord storage for safety and convenience. 

The K-Slim also has a hot water button on the top of the device to dispense steaming hot water for tea and other beverages.

The K-Mini and K-Slim also come with a built-in coffee grinder that allows users to grind their favorite beans into the ideal consistency for making espresso, cappuccino, and lattes. 

The user can select from one of six preset settings or customize their own grind size to get the perfect cup of coffee. 

Both models also offer a variety of settings for temperature, strength, and size to choose from, so users can tailor their brew to perfection. 

Additionally, another design feature of the Keurig Mini is the easy cord storage option on the back of the machine, which lets you store the cord inside the device when you are not using it.

The Keurig Slim, however, still has the cord hanging out of the back.

If there is anything wrong with your good coffee machine, Keurig allows you to have a 1-year warranty.

With the K-Mini and K-Slim, users can enjoy all the flavors and aromas of freshly ground coffee without ever leaving home.

The K-Mini and K-Slim also come with a special cleaning feature that ensures the machine is always ready for use. 

The descaling system helps dislodge debris and buildup from the internal parts of the machine, while the integrated rinsing cycle flushes out any leftover residue. 

This makes it easy to keep your coffee maker in good shape and get the most out of your coffee-drinking experience. 

There are also fewer parts in the coffee makers, making it easier to clean between each regular brew cycle.

Plus, with both of them being compact coffee makers, the K-Mini and K-Slim are the perfect coffee maker for smaller spaces and can fit into virtually any kitchen, even a small kitchen.

They are also generally at a more affordable price due to their smaller, more compact size.

Finally, both models include a convenient auto-off feature that will turn off the machine after two hours of inactivity. 

This is an energy-saving feature that conserves energy and helps you save money while still having fresh cups of coffee anytime you want. 

With all of these features, the K-Mini and K-Slim make it easy to enjoy delicious coffee, whether it be iced coffee or hot coffee, you will never have to leave your home.

You can choose the clear winner depending on your own personal preferences.
