How to Size your child for a String Instrument
This guide will walk you through measuring your child for a string rental. All you need is a tape measure or yardstick, and your child.
Tips to measure arm length
Have the player extend their left arm completely straight (but not overextended) with no bend in the elbow or wrists.
Violin

| 21" - 22" | 1/2 |
