CA. 7 cm. My espresso cups fit perfectly underneath. If you want a larger cup for cappuccino, just under 8 cm will work, but then you mustn't fill it too much as you have to lever the cup in and out. However, there is a 3D pressure with which you can get a lot of space.

Hello Community...Espresso cup perfect, cappuccino is also ok. If I do use a larger cup, then I remove the drip tray, yes it drips but not a problem for me. LG

Hello, unfortunately I no longer have the machine. I had two of them, both were broken after a short time (pump).
So I cannot recommend the machine. Greetings

The distance between the outlet and the draining grid is 7.5 cm. However, I also use cups that are 8 cm high by lifting them at an angle under the outlet, which works very well.
