How to find your jock strap size

Support yourself during athletics by wearing the appropriate size of jock strap. Jock straps prevent unnecessary injuries for men while playing sports. The elastic band accommodates a wide variety of waist sizes and the cricket box sizes vary for comfort. Both men and boys wear jock straps, which fit similarly to underwear, either over undergarments or beneath undergarments. Choosing the right size is just like picking out a new pair of boxers or briefs -- you want the fit to be comfortable and wearable for long periods of time.

Determine if you will wear the strap under or over your boxers or briefs. Wearing the jock strap over the underwear may push the waist size up one, if you are on the cusp of two sizes. Choose boxers or briefs that fit tightly, not loosely, if wearing over the undergarments.

Measure your waist for an accurate size. Use a flexible tape measure and wrap it around the widest part of your waist. Use this measurement to determine if your jock strap is a small, medium or large. Take your measurements while wearing boxers or briefs if you will be wearing the jock strap over undergarments.

Match your waist size to the jock strap size chart. Most jock strap size charts are located on the package; however, a small waist for men is typically a 66 to 81 cm (26 32 inches). A medium is 86 to 96.5 cm (34 to 38 inches). A large is 101.5 to 112 cm (40 to 44 inches). Child jock straps will be the same size as their underwear. Go up one size if the boy is wearing the strap over underwear.

Buy the cricket box size separately if the items do not come prepackaged together. Typically, the box is sold with the size of the jock strap; however, if the box is not included, buy the box size depending on your preference of small, medium or large.


Ask to try the jock strap on before buying to obtain an accurate fit.
