Measurement Instructions:
  1. ​Lift the student's left arm and extend it fully to the side, palm facing upward, fingers flat, and straight out.
  2. Place the yardstick under the chin, touching the base of the neck - you are going to measure from neck to palm as this is where the violin will sit.
  3. Then determine the measurement from the neck to the center of the palm where the thumb meets the palm.​
Instrument Sizing Video
Please Note:
We never "grow into a violin" size. Playing an instrument that is too big can cause a multitude of problems including improper technique and the physical health of the child. That is why The Loft Violin Shop's rental plan and 100% trade in policy is so valuable.
