In grand pianos the frame and strings are horizontal, with the strings extending away from the keyboard. The action lies beneath the strings, and uses gravity as its means of return to a state of rest. There are many sizes of grand piano. A rough generalization distinguishes the concert grand (between 2.2 and 3 meters [7 ft 3 in–9 ft 10 in]) from the parlor grand, or boudoir grand, (1.7 to 2.2 meters [5 ft 7 in–7 ft 3 in]) and the smaller baby grand (around 1.5 meters [4 ft 11 in]).
