String Instrument Size Guide

 When measuring your child for an instrument, you will need to consider either their height, the length of their arm, or both. A general rule of thumb is that if your child is on the border between sizes, to “round down” and pick the smaller size. Most often, this will be the correct instrument size for your child. If they are truly on the border, it is much easier to develop proper instrument technique on an instrument slightly-too-small, than too large. 

 When measuring length of the arm, have your child stand with their left arm extended out to the side, parallel with the floor. Place a yard stick on the arm, and measure from neck to wrist. Consult the table below to determine your child’s violin or viola size.

 When measuring your child’s height, have them stand with good posture on a level surface, without shoes. Consult the table below to determine your child’s cello or bass size.
