From the above  tables, we can summarize the above data:
                                                               For Single Jersey fabric

finished Gsm
Count
Finished Diameter
140
30s/1
Machine dia = Finished dia
160
26s/1
Machine dia +1 = Finished dia
180
24s/1
Machine dia + 2 = Finished dia
200
 20s/1
Machine dia + 3 = Finished dia
220
18s/1
Machine dia + 4 = Finished dia



N.B: If the fabric is to be Enzyme washed, the stitch length should be kept (10%) less than the normal range. Because, enzyme wash reduces the total weight of the fabric by removing the floating fibre and hairy fibre

For average color, the finished GSM varies 2-4%
If the GSM varies 25-30%, it is not only necessary to control the VDQ pulley dia but also yarn tension & take-up roller
