Correct size is crucial for success. Too large an instrument can cause poor technique and improper posture.
Factors
which may affect sizing are height, arm length and hand span. If an instructor is unavailable to assist in determining the
correct size use a ruler or yardstick to:
- Measure the left hand span between the pinky and index fingers.
- Measure
the left arm length from the shoulder socket to the end of the middle finger.
- Determine the height of the player.
- If
an instrument is present, have the student seated with knees bent at 90 degree angle. The upper rim of the cello should rest
at the sternum (breast bone) and the left knee should contact the curve of the lower bout corner. The thickest string (C string)
peg should be near the left ear with the neck of the cello a few inches from the shoulder of the player.
The following
chart is approximate sizing. Just as in fitting shoes, often there may be an “average” size for a particular age
group but the range of sizes varies greatly. For the best fit, seek the assistance of an instructor or store personnel.
