Piano aid

Upright or vertical pianos are so named because their strings run in a vertical position contrary to grand pianos whose strings run in a horizontal position. The difference between the various types of verticals is based on their height measured from the floor to the top of the piano lid. The greater the height, the longer the strings. And longer strings produce better tonal quality. The standard width of an upright is 5 feet and the depth between 2 and 2 ½ feet. So, to leave room for the bench, you should allow for a space of 5 foot wide by 5 foot deep.
