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.
