What is the height of the barre

Most ballet barres are fixed at 32 to 46 inches from the floor.. Many ballet schools will set up a double barre, one at 32 inches and one at 46 inches. I helped set one up years ago for a dance school. I seem to remember the instructor telling the students to choose the barre closest to the height of the waist. But that was ballet, not the barre exercise program.
