How to Measure Knee Length

Measuring the knee involves taking a measurement of the knee cap. This may be necessary if an athlete needs to buy specific types of equipment like knee pads or guards for sports like baseball, football or hockey. You can measure the exact length of your knee cap in just a few seconds using a standard, flexible tape measure.
