This is a powerful fan, and I am very pleased with its performance. If you are looking for a standing fan that can really move the air, this is the one. It took my husband about 10 minutes to put together. It is rather heavy, which is good because it is unlikely to fall over. The base is wide and stable. I can't remember the measurements, but it is pretty tall, maybe about 4.5 to 5 feet at its highest. My only disappointment with the fan is that the decorative cone-shaped cover that is intended to hide the screws that hold the fan to the base does not secure tightly. The decorative cover slips over the shaft and then just rests on the base. This would be ok, except that there is a gap all-around (think of a putting a 1/2 in diameter dowel through a washer that has a 3/4 in hole) that allows the decorative cover to move around. Still, it's a great fan. I highly recommend it.
