Violins come in 8 main sizes. The size corresponds to the length of the body of the violin (not including the neck and scroll). The smallest common size is 1/16 (just 9 inches or 23 cm), and the sizes work their way up through 1/10, 1/8, 1/4, 1/2, 3/4, 7/8 and finally 4/4 or full size (about 14 inches or 36 cm). Generally speaking, you know if a violin fits if you can reach the notes comfortably with your left hand when holding up the violin.
First, look on the bow itself. Sometimes there is writing on the bottom limb or on the side of the riser. A typical writing might read, 58/30#. This means that you have a 58 inch bow from tip to tip and a poundage of 30 at a 28 draw length. Since the length of the bow is 58 inches you would need a 58 AMO bowstring. However, AMO measurements have actual string lengths that are 4 inches less. Therefore, your 58 AMO string is really only 54.
