In my case, it is 190cm from the suspension point to the ground, and you should allow an additional 30cm for the suspension. Suspending it only with a carabiner is tedious, so I bought a bigger shackle.

Of course, it depends on your suspension device and desired seat height. A ceiling height of at least 215cm is required.
From the suspension loop to the bottom of the fabric is approx. 165cm.
