Attached is a .xls spreadsheet showing the length of 4/4 - S42 and 3/4 Spircore - S3885 strings. I got it from the good folks at Connolly and Co., U.S. distributors for Thomastik-Infeld. The info on silk length at (1) the ball end & (2) the length of the string between the silk on the ball end and the silk at the top was very helpful.
