How big is a grand orchestra guitar?
The Grand Orchestra’s body length is 20 & 5/8″, body width is 16 & 3/4″, and the depth is 5″. Compare that to the most popular Taylor Guitar shape, the Grand Auditorium, which is 20″ x 16″ x 4& 5/8″. While the GO is certainly larger, the biggest difference is the actual depth of the body.
