What play space do you need to play comfortably?
To have fun playing, you need to feel totally comfortable. Among other things, that means optimising your play space: ideally, to delimit the area, you need the length of one cue (average length being 1.45m) between the edge of your table and the walls of the room. If you can, provide for an extra 5cm for your stroke (the back and forth motion of the cue before you hit).
To summarise, you need a 21.5 m² space (514 x 418 cm).
