Concert grand harps like my own pictured above weigh 80 - 90 pounds. Mine weighs about 85 pounds, and the cart I haul it in weighs 35 pounds, for a total of 120 pounds. Other types of harps come in a variety of weights. For example, my gut-strung folk harp made by Thormahlen is 26 pounds. My Irish wire-strung lap harp made by Triplett is 12 pounds.
