How to Measure for a String Instrument

Have the player extend their left arm completely straight (but not overextended) with no bend in the elbow or wrists.

  • Measurement 1 (neck to wrist) This indicates the most appropriate and comfortable size for the player.
  • Measurement 2 (neck to palm) This indicates the largest size the player could use.
