The way to measure CF zipper is not very tough, but sometimes it makes much panic for developers. Usually, it depends on the fabric & zipper nature or properties. Additionally, we should have a prior idea about the shrinkage percentage of fabric & zipper tape especially washing garments. Some zipper measurements are not very complicated such as pocket, leg opening, armpit, hood attachment etc. Because, these zippers size does not differ from size to size, but the dimension of center front zipper may vary from one size to another size.
A) If the garments do not exist any high neck then the rules will be like below:
Suppose if the body length from HPS – 31”
Front Neck Drop from HPS – 4.5”
Rules: (Body length from HPS – Front neck drop) – 2% to reduce sewing puckering
= (26.5”- 2%)
Front collar height – 3”Rules: (Body length from HPS – Front neck drop) – 2% to reduce sewing puckering + Front collar height
= (26.5”- 2%) + 3”
= 25.97” + 3”
C) Beside this, we can measure the CF zipper length considering garments back length. If the garments exist backdrop tail and the zipper goes up to high neck from bottom then the rules will be like below:
drop from HPS) – Front neck drop from HPS + Front collar height – Hem drop from CF to CB if exist – 2% to reduce sewing puckering.
