Hand Sewing Needle Sizes

Hand Sewing Needle Size Table

C. S. Osborne hand sewing needle diameters use the Standard Wire Gauge system. In this system a higher gauge number means a smaller needle diameter. For example a 20 Gauge needle's diameter is less than a 10 gauge needle's diameter. Here are the U.S. and metric diameters for needle gauges:
