Each knee walker manufacturer provides a height range for accepted use of their products. These height ranges are a general guideline, but don't account for all of the different leg & torso proportions that are out there. The best way to make sure that a knee walker model is a good fit, is to measure the distance from your knee to the floor.
If your knee to floor measurement is between 18.75" and 21.75" you can use any one of our knee walker models. Of all units the Free Spirit Knee Walker is the most versatile, so if you are on the shorter or taller side of the spectrum, it's your best bet.
To see if our knee walkers are a fit for you, check to see if your knee to floor measurement is within the knee pad adjustment heights below.
