Choose your size in US sizing. Use the conversion charts and measuring tips below to find the right fit.
Use a ring sizer
A ring should pass over the knuckle and sit comfortably on the finger. Measure in the evening when your fingers are warm.
Measure a ring you already wear
Measure the inside diameter of a comfortable ring, then compare that measurement with the conversion chart. The displayed illustrations are not an actual-size measuring tool.




The guide includes sizes beyond this pilot’s selectable range. Ask our team about availability if your size is not listed.
