Chellos come in a variety of dimensions to fit students of all ages and sizes. Most teen-agers and adults find full-size cellos most comfortable to play, while younger cellists typically use half-size, one-quarter-size or even one-eighth-size cellos. Before buying a cello, it’s essential to ensure you can hold and play the cello comfortably. Experts in music stores are generally happy to guide you, but it’s also helpful to know how to size a cello yourself.
Place the cello between your knees on a 45-degree angle. Lean the top of the cello's body toward the center of your chest.
Note how close the lowest tuning peg (C peg) is to your left earlobe. The C peg should be touching, or almost touching, your left earlobe when your head is held straight.
