Overall, I really like the light, it provides a great visual impact to my dining area without closing in the space. To answer the measurement questions, the metal rod in the center that holds all the arms is 72 cm in height. I installed it very close to the base and it measures approx 82 cm from the ceiling. Each arm is approx  110 cm long with the glass bulbs. 
When I ordered this on a weekend, I had concerns about the height and it being too large for my table and tried to cancel the order 20 minutes after but cancellation wasn't possible. Thankfully it worked so I didn't need to return it
