Several factors play a part here. Golfers’ physique and club-set size. Recommended space is 10ft W x 15ft L x 10ft H. If you intend to use your irons only, 10ft W x 10ft L x 8.5ft H will work fine for you. But, if you want to use your driver and woods, it is advised that you follow the recommended space requirements with higher ceilings.
