The Hangar is designed to accommodate most of the popular makes and models. To find the correct Hanger for your instrument, measure the distance from the lower pert of the headstock (where it would sit in the yoke), to the tail of the instrument. Most guitars will fall within the 89.5cm clearance of the origional Hangar. The clearance on the Hangar XL is 98cm, while the XXL has 116.5cm clearance. The XL & XXL will acomodate most baritone and bass guitars.
