When purchase a new string instrument for kids, it is essential to get the correct size, so they can comfortably play and get enough motivation as they advance their skills. A violin that is too big will be heavy for a child to hold. Playing a heavy violin will make their arms tired and sore and may also hurt their neck and eventually their back. Also if they have trouble reaching the notes it will be very difficult to play in tune. Aside from the discomfort, none of this will be good for their motivation to play music!
Violins usually come in nine different sizes: 4/4, 3/4, 1/2, 1/4, 1/8, 1/10, 1/16, and 1/32. 4/4 (full size) being the biggest and 1/32 size being the smallest. Most of adults use a full size violin.
Violas come in a range of sizes, most often 16 1/2″, 16”, 15 ½”, 15”, 14”, 13”, and 12″, the largest common size is 16.5″. Adults generally play a 15.5″ to 16.5″ viola.
Cellos come in a range of sizes in the same way(different measurement though) as violins do: 4/4, 3/4, 1/2, 1/4, 1/8 and 1/10. Most of adults use a full size cello.
To measure what size violin best suits you, you need to know the length between your neck and the middle of your left-hand palm or left wrist. This is measured when your hand is fully extended and raised perpendicular to your body, just like holding a violin. Many teachers prefer students to use the length from the neck to the wrist for measurement instead of the neck to mid-palm approach. The violin size determined by the neck/wrist approach would be the size that is more comfortable for students to hold. The violin size determined by the neck/mid-palm approach would be the biggest size students should use. By using our chart, you will find the size which most probably will be the best for your child.
