There are four classes of vertical pianos, including uprights. Spinet pianos are less than 3 feet tall. Consoles are between 40 and 44 inches tall. Studios, or professional upright pianos, measure 45 to 50 inches tall. Normal upright pianos are the tallest at more than 50 inches.
Upright pianos were popular in the 1920s through the 1940s in the United States. The box that creates most of the reverberating sound in an upright is above and below the strings rather than spread out over the depth of the piano.Learn more about Musical Instruments
