The frog is made from 2 1/2" wide webbing, 8 1/2" long (so use 17" to double the thickness and create belt loop; the belt loop opening needs to be 3 3/8" wide. The helve strap is 1" wide and 6" long. the two stud retaining straps on mine are slightly different widths = top is 1 /38" while the bottom is 1 1/2" and they appear to be 4" long.
