how much does a upright piano weigh
1 The smaller studio uprights usually weigh between 400 and 600 pounds. 2  The monstrous full vertical or large upright piano can weigh as much as half a ton.  A studio piano's center of gravity is also lower than a large upright's, as it is about 4 feet (1.2 m) tall as opposed to a large upright's roughly 5-foot height.
