What Size Box violin?

Violins and violin-family instruments come in smaller sizes to make it easier for children to learn to play. Getting the proper size is even more important than getting the correct size of clothes. An instrument that is too big can be nearly impossible to play, while one too small may not produce the best tone and technique. Determining the size of the instrument is easy! 
 

Measuring with a yardstick:

With the left arm fully extended, palm up, and a yardstick under the chin to simulate a violin, record the measurement in the center of the palm. At this point you don't want any slack in the arm, the measurements below will indicate the correct size of the instrument with a proper bend in the elbow.
