With your leg straight measure 2cm (3/4) inch below your kneecap around the circumference of your leg.

  • X-Small: 31-33cm (12-13 inches)
  • Small: 33-35cm (13-14 inches)
  • Medium: 35-37cm (14-15 inches)
  • Large: 37-40cm (15-16 inches)

Our suggestion is that if you plan on using your knee sleeves for multiple movements and combinations then go with a 5 mm knee sleeve. If you plan on using the sleeves for mostly barbell work, weightlifting, powerlifting, etc. then use the 7 mm knee sleeve.
