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.
Arrow sizes vary greatly across cultures, ranging from eighteen inches to five feet (45 cm to 150 cm). However, most modern arrows are 75 centimetres (30 in) to 96 centimetres (38 in); most war arrows from an English ship sunk in 1545 were 76 centimetres (30 in). Very short arrows have been used, shot through a guide attached either to the bow (an overdraw) or to the archer's wrist (the Turkish siper).
