How big is one moose antler?

One moose antler can vary significantly in size, but typically, a mature bull moose's antlers span about 3 to 5 feet wide and can weigh up to 30 pounds or more. The size can be influenced by factors such as the moose's age, genetics, and overall health. Antlers are shed and regrown annually, often growing larger each season until the moose reaches maturity.
