One of the most notable features of them all with some small exceptions is that they are all fairly tall and narrow as they are designed to hold a good deal of coffee and yet still fit into standard cup holders and bottle pouches.
For those of you who have or who are thinking of picking up a Keurig coffee maker you should know that many thermal coffee mugs and tumblers will not fit under the Keurig machines. Even with the drip tray removed and the lid removed from many travel mugs they are simply too tall.
This isn't really their fault either as Keurig machines are designed to brew small batches of coffee - much smaller than the capacity of the most common sized travel mugs 14-20oz.
There are however a number of quality travel mugs that are short enough to work with Keurig machines. Most of them require the removal of the drip tray on the machines but they do work.
KeepCup makes some nice super-small travel mugs that are perfect for Keurig coffee makers. They are sized perfectly and look pretty cool too.
If you want a high performance travel mug however you'll have to go to Contigo which has partnered with Keurig on a mug that is "designed" specifically for the Keurig machines. It's basically a small version of their very popular Auto-seal line of travel mugs.
Basically it's still too big for most Keurig portions in my opinion but it is a really good mug and worth checking out.
To compliment this page let me point you towards this post which lists a whole bunch of the best options for Keurig sized travel mugs. If you have a Keurig - or are buying a gift for someone with a Keurig machine - this page will be helpful in finding a good mug sized appropriately for all the Keurig coffee makers, Keurig mini included.
