I was bit worried about the size. but I would say it's perfect size. Takes up minimal space. I really like the design and everything, but mine came with a damage... It could be only mine alone, but I think they need to do better on quality control. After all, it's not a cheap headphone hanger.
dimensions (cm): clamp part(w/o screw): 4.7 x 2.5 x 5.5, hanger: 10.5 x 2.5 x 1.8
