An upright piano is a piano with a rectangular wooden casing in which the strings run vertically, so it takes up less space than a grand piano. Upright pianos vary in size, so their weight varies. Large or full-size upright pianos can weigh more than 800 pounds.
A small upright piano typically weighs between 300 to 500 pounds. In comparison, grand pianos can weigh as little as 500 pounds and as much as 1,200 pounds. A concert grand piano can weigh as much as 1,300 pounds. Those interested in purchasing an upright piano can contact the manufacturer to get the exact weight of the specific make and model.
