How to Measure Your Student For a Violin or Viola

  1. Follow the recommendation of your student's orchestra director or private teacher <OR>
  2. Use a tape measure or yardstick and follow the directions below:
    • Have your student stand straight-up with their left arm extended to the side at shoulder height (see picture below)
    • Your student's left arm should be fully extended without any bend
    • Gently place a tape measure or yardstick to the side of the student's neck
    • Measure to the middle of the student's palm (on their left hand)
    • Use the chart below to rent the appropriate sized instrument for your student

  • As your student grows they will need larger instruments, until they reach a full-sized instrument
  • When renting from PM Music Center all instrument exchanges are free of charge
  • We do not recommend purchasing an instrument until your student is ready for a full-sized instrument
