Just take a piece of string or tape and mark it from the top of one pulley to the top of the other that are normally on there. Then do that from the same tops except run it down and under the added pulley. Subtract the first measurement from the second and add that number to the overall length of our serp pulley. Doing this in my head I think it would add about 6"'s or so but that is pretty ballparked.
