Student model string instruments come in a number of different sizes so that instruction may be introduced at any age (or size!).
The Arm Length Chart (below) is used when measuring from the side of the neck to the middle of the palm when the arm is extended out to the side. It will often yield the most accurate results but the Age Chart can be used to confirm the results found with the Arm Length chart.
The charts below show instrument recommendations for a given arm length measurement for a child of average height for their age. Your child’s own height should be taken into consideration when using this table as a guide.
If in doubt, it is usually better to get a smaller size as the instrument will be easier to play.
