Cello - Sizes

Sizes

Standard-sized cellos are referred to as "full-size". However, cellos come in smaller (fractional) sizes, from "7/8" and "3/4" down to "1/16" sized cellos (e.g. 7/8, 3/4, 1/2, 1/4, 1/8, 1/10, 1/16). The smaller-sized cellos are identical to standard cellos in construction, range, and usage, but are simply 'scaled-down' for the benefit of children and shorter adults. Note that a "half-size" cello is half the volume of a full-size, not half the length (i.e., the 1/8-size cello would be "half-size" in terms of length). A 1/10-size cello, for example, which is meant to be used by small children, is only slightly larger than a violin (and as such can be played by an adult player like one), but about twice as thick, and the C string tends to be quite slack due to the difficulty for such a small string to produce a sound that low. Many smaller cellists prefer to play a "7/8" cello as the hand stretches in the lower positions are less demanding. Although rare, cellos in sizes larger than 4/4 do exist. Cellists with unusually large hands may play a slightly larger than full-sized cello. Cellos made before approximately 1700 tended to be considerably larger than those made and commonly played today.

Around 1680, string-making technology made lower pitches on shorter strings possible. The cellos of Stradivari, for example, can be clearly divided into two models, the style made before 1702 characterized by larger instruments (of which only three exist in their original size and configuration), and the style made during and after 1702, when Stradivari, presumably in response to the "new" strings, began making smaller cellos. This later model is the one most commonly used by modern luthiers.
