Quick Answer:

Violin sizing requires precise arm measurement: have your child extend their left arm straight out to the side, and measure from the neck (base, where it meets shoulder) to the center of the palm. This measurement in inches determines their violin size.

How to Measure

Step 1: Have your child stand straight with their left arm extended directly to the side, parallel to the floor. Step 2: Measure from the center of the neck (where it meets the shoulder) to the middle of the palm. Step 3: Record this measurement in inches and match to size chart.

Sizing Tips

  • Measure multiple times to ensure accuracy
  • Always measure with arm fully extended
  • Consult your teacher for verification
  • If between sizes, always go smaller

Frequently Asked Questions

Why is violin sizing so important?

A too-large violin causes tension, poor technique, and potential injury. Violinists hold the instrument for extended periods, so proper fit is critical for comfort and development.

How often should I remeasure?

Every 6 months for children under 10, or whenever your teacher suggests the violin looks small. Growth spurts can mean sudden size changes.

Can a professional measure my child?

Yes - violin teachers and violin shops will measure your child accurately. This is recommended, especially for your first violin or if you're unsure.
