Violin comes in 8 different sizes: 4/4 (also called Full size), 3/4, 1/2, 1/4, 1/8, 1/10, 1/16. 4/4 size being the biggest and 1/16 size being the smallest. All adults, regardless of their size, use the 4/4 violin. There is another uncommon size, 7/8, usually used by female professional violinist who wants a full-size violin sound but whose hand might be a little small for the full size violin. So violin makers would make violins just a little smaller than full size to accommodate these players.
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 (when your hand is fully extended and raised perpendicular to your body, just like holding a violin). Some 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.
If you have a teacher, you should ask for your teacher’s recommendation. If you don’t have a teacher, we would recommend using the neck/wrist approach for students not using full size. For students who are deciding whether to used 3/4 or 4/4 size, use the neck/mid-palm approach. This is because it is always better that students feel comfortable holding and playing the violin.
The following chart lists the length of each violin size. Find your length using the your preferred approach and use that to determine the size of violin to get.

Cello Sizing Tips:

Seat the child (or yourself) so that the knees are bent at a ninety degree angle. The instrument should rest such that the upper rim of the cello body rests on the sternum (breast bone), and the left knee contacts the curve below the lower bout corner. The C string (the lowest string) peg should be near the left ear, with the neck a few inches away from the shoulder, and the left hand able to reach both ends of the fingerboard with ease.
