Keurig coffee makers have openings that are 5 1/2 inches tall. If you remove the drip tray the opening expands to 6 1/2 inches. Many high end travel mugs do not fit these demensions even with the drip tray removed.
Below I’ve features some of the bets travel mugs to fit this opening. All mugs here stand at a maximum of 6 1/2 inches so they will all fit either just perfectly or with a bit of room to spare.
