It's my understanding that the difference between a violin and a fiddle is the bridge. The bridge on a violin is flatter that the fingerboard. However, on a fiddle, the contour of the bridge is made to match the contour of the fingerboard.
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).
