Travel Mugs That Fit Under The Keurig Mini, K-Mini, & K-Mini Plus: Your Best Options

Got a Keurig Mini coffee brewer? Thinking of picking one up? Be careful which model you get if you are a regular travel mug user.

Most small travel mugs don’t fit under the older model Mini Keurig machines such as the K10, K15, or B31. Those mini brewers truely are small and they are best used for regular coffee cups in and around the home.

The new Keurig K-Mini and K-Mini Plus brewers however give you a lot more space to use a taller mug if you like but even they have their limitations.

First let’s look at specs.

The Original Keurig Mini (K15/K10/B31)
Keurig Mini K15If you have or are getting an older Keurig Mini then with the drip tray in place you can fit a mug of 4-1/8″ in height under the spout. This is really only enough space to fit a standard coffee cup under and even then it can’t rally be a tall one.

If you are fine removing the drip tray as many owners do out of necessity then you get one additional inch of clearance.

Anything measuring 5-1/8″ or less will fit under the spout with that drip tray out of the equation. In most cases most tall coffee mugs will fit under the spout but only a few super short insulated tumblers and travel mugs will fit.

Lower on this page I’ve reviewed your best options for mugs that are short enough to fit under a Keurig Mini but to summarize for you let me point you towards the KeepCup 8oz mug, the 10oz Contigo Autoseal Mug, and the Insulated Doppio Tumbler from GSI Outdoors.

Each of those insulated travel mugs mugs will fit under the K15 Mini when the drip tray is removed from the base and the GSI Doppio tumbler will even fit with the drip tray in place.

The New K-Mini & K-Mini Plus

In 2018 the new K-Mini was released as a better made product. Not only are the new machines better made, skinnier, and more feature rich, they are also more accommodating to travel mugs, tumblers, and larger coffee mugs of all shapes and sizes.

With the drip tray in place on the K-Mini and the K-mini Plus any mug measuring six inches or less will fit just fine and when the drip tray is removed you have enough clearance for a seven inch mug.

One of the best selling travel mugs in recent years is the 16oz Contigo West Loop and it measures 6-3/4″ in height with the lid off so it will fit just fine under then K-Mini when the drip tray is taken off.

Better yet the actual Keurig branded insulated travel mug is 12-ounces and 5-1/8″ tall so it will fit under the New K-Minis with plenty of clearance and without having to remove a drip tray.

There are actually a ton of insulated tumblers and travel mugs that will fit under the K-Mini and K-Mini Plus but as is always the case some are leaps and bounds better than others. Lower on this page I’ll review what I believe to be your best options but for starters a quick list of my favorites includes the aforementioned Keurig 12oz tumbler, the 12-ounce YETI Rambler, and the 10-ounce Contigo Autoseal.

Even still you have to really go out of your way to find a good insulated travel mug for one of these small machines. Not every store carries these shorter tumblers but they exist and you even have options in terms of quality and brand which wasn’t the case back when the first Keurig Mini was released.

I have an older post on keurig sized mugs but I wanted to highlight the mini brewing machines in it’s own post because, well, your options are much more limited and you can’t just buy a small mug and assume it will fit.

Travel Mugs For Keurig Mini Coffee Makers

The opening on an older Keurig mini is four inches and if you remove the drip tray the opening expands to five inches.

In most of the larger Keurig brewers the opening with the drip tray removed is around 5 3/4″ so this is noticeably smaller.

For a travel mug to fit the Keurig Mini it needs to measure less than 5 inches in height with the lid removed.

I’ve narrowed the field down to three really excellent insulated travel mugs that are small enough to fit into this space and listed them below.

I hope this helps!

The Oxo Good Grips Mini LiquiSeal Travel Mug

The Oxo Good Grips 9.5oz Mini LiquiSeal Travel Mug

The 9.5 ounce Oxo Mini travel mug barely fits under the Keurig Mini brewers so long as you remove the lid to the mug and the drip tray for the brewer. It is exactly 5 inches tall sans lid so it’s a tight squeeze but it’s probably the best performing mug in this size range.

If you want a mug that will really give you good insulation then this is the best option of the three listed on this page. The mug is also very leak resistant too which is great for the car.

KeepCup Barista Standard 8-Ounce Reusable Cup

The KeepCup 8-Ounce Reusable Coffee Cup

If you want something that’s slightly insulated and really small then you have to go with Keepcup’s 8oz mugs. They come in many different color combinations and they are made of a somewhat flexible silicone like plastic. Much like a paper cup can flex a bit these cups will do the same.

You can expect this cup (with it’s lid) to keep your coffee hot longer than a basic coffee mug but not more longer than 30-40 minutes. It’s super short too so you can easily get it to fit under a mini Keurig brewer, either the B30, B31, or K10.

BODUM Anywhere Travel Mug with Spill Proof Locking Lid

BODUM Anywhere 8oz Travel Mug wit Spill Proof Locking Lid

A lot like the Oxo Mini featured above this mug is 5 inches exactly when the lid is removed making it a perfect fit for the smallest Keurig brewers. This mug isn’t going to be be quite as thermally insulated but it will keep things hot for up to an hour depending on how fast you drink your morning coffee.

For the road this is actually a great mug because you can drink from anywhere on the lid’s circumference. You can seal it so it doesn’t leak or spill and there’s no handle to get in the way. I’m fond of this mug but it can be hard to find in stock at times.

In any event I hope this helps you out just a bit.

I’ve listed the mugs I would buy for the owner of a Mini single cup coffee maker in order of my preference but they all are worth buying if you ask me.

Also, If you are shopping for a mug to fit under a Keurig K-Mini coffee maker then your options are a lot larger. The K-Mini was redesigned to offer a much taller opening for the mug.

Even with the drip tray in place you can fit most small travel mugs under the spout. In fact you’ll probably be able to use nearly any small sized insulated mug you want. The opening accommodates anything up to seven inches tall when you remove the drip tray.

This is far more space than is needed for a single cup Keurig machine in my opinion but it does make things easier on you.

Anyway, make sure to check out my page for insulated espresso mugs and cups if you are looking for that sort of thing.

Most mugs featured on that page aren’t going to be road worthy but will be great for around the house. For commuting or general portability then stick with an stainless steel tumbler like those featured above or over on this page.
