By industrial standards zippers have sizes designated as size 3, 4, 6, 7, 8, 9, 10, 12 and so on. The numbers are just technical jargon and do not reflect any specific size as numbers. In general, the bigger sizes mean a stronger zipper.
The coil zippers are usually smoother to use than the tooth zippers by nature of their design. add a comment
