The cello, about 4 feet long (or about 1 ¼ meters), is made up of three main parts: the body, strings, and a separate bow. Given the range of the cello, its construction is proportional to that of the violin being approximately twice the size of the violin, which is generally about 2 feet. (By contrast, the viola is not proportional in size to the violin, being only slightly longer than the violin at about 26” instead of 3 feet, or ⅔ meter.)
