m-station Talent is 2-metres deep, when it is positioned on a slope, where you can keep the ball in the air with your feet and head. In addition, the player must have an area of 1.5 – 2 metres to stand on. So 3.5 to 4 metres are fine for exercises, in which you are standing close and have the ball in the air.
If you want to make passes along the ground, you do not need as much space, because in this case m-station Talent is placed vertically, and the depth is only 120 cm. The player can easily manage with 2 metres, so that requires a total of just over 3 metres.
Still not sure how much spaces you need, check out some of our users videos.
