I tried my pole in a space 2m (roughly 6 ft 8″ I reckon). Theoretically the height was ok, except that on one side the ceiling sloped down, so I hit my head a few times… and climbing from kneeling was hard, because the little screws on my Xpert scratched my feet… and on spinning it spun too fast for me hehe, plus as mine is a chrome pole, every inch counted (i.e. CKR into bow and arrow into handstand was impossible, even just CKR into a handstand was hard, because all of a sudden, I was too low for the hands).
We took it down and got an Xstage (we couldn’t find any joists when we knocked the ceiling- it’s a top floor flat, and the expert had been in a corner underneath a low beam- the rest of the flat, the ceilings are 2.6m). I love my XStage, and I love wearing heels (unfortunately, everytime my daughter is around when I put my heels on, she decides it’s time to come and catch the heels- little pole dancer in the making), which I couldn’t in the 2m space, because it was so short, I reached the top with my hand even without heels hehe
Depending how high your ceilings are you might need an extension- for my 2m ceiling, I needed a 75cm “extension”, because Xpole is usually meant for higher ceilings than mine lol
