The common rule for most pieces of safety gear is to aim for a comfortable snug fit which also applies for the fitment of knee braces. The padding for the hinge point which sits either side of the rider's knee joint should be snug too tight and the rider will experience pain when riding and too loose the brace may slip down the leg and not sit in the correct place on the knee.
