Violins come in nine sizes. Adults—generally from age 11 and older—will use a standard, full-sized violin. For children, there are also 3/4, 1/2, 1/4, 1/8, 1/10, 1/16 and 1/32 violins. The full-sized violin is also referred to as a 4/4 size.
There are two ways to measure a young player for a violin. With the student’s left arm fully extended away from his or her body, measure from the base of the neck to either the wrist or the center of the palm. If your child has a violin instructor, you may want to ask which method the instructor prefers. The neck-to-wrist measurement will indicate the most comfortable size for the student. The neck-to-palm measurement will determine the largest instrument your child should play.
The following chart will help you determine what size instrument your child needs, based on which ever measurement you choose.
