Acupuncture Needle Gauge Size Conversions Chart

19th Nov 2019

Acupuncture needles come in a variety of lengths and gauges. How these measurements are written on needle packaging can vary based on the style of the needle or where in the world they are sold.

The gauge of a needle references needle thickness.

The length is the overall distance from tip to end, not including the needle handle.

You can find needles on our website in specific sizes by using our search bar or filtering by actual sizes. We carry many different styles such as Spring Handle, Pipe Handle, and Plastic Handle Acupuncture Needles.
