Needle Size Conversion Chart

 

Needle and sewing machine companies have evolved many needle sizing conventions. The most popular are the Organ / Singer and Metric sizes that we show for every product. For example 16/100 means Organ / Singer size 16 or Metric size 100. This chart lets you convert any needle size into roughly equivalent sizes in other sizing needle sizing conventions.
