How to Choose the Right Knee Sleeve Size
Share
A knee sleeve can only do its job if it fits. If it is too small, it squeezes and quickly ends up in a drawer. If it is too large, it slides down and gives little support. The good news is that finding the right size takes only a tape measure and two minutes. This article shows how to measure correctly, which size matches your measurement and how to recognize a sleeve that does not fit.
Why the right size matters
A soft sleeve works through gentle, even pressure around the knee, and that pressure is determined by the size. The right size feels snug and stays in place when you walk, climb stairs or sit, without pinching behind the knee. It also lets you bend the knee freely. More about how this gentle pressure works is in our article on how compression works on the knee.
How to measure
- stand upright with the leg relaxed and straight, ideally barefoot,
- find the top edge of the kneecap and mark a spot on the thigh 10 centimeters above it,
- wrap a soft tape measure around the thigh at this height, snug but without pressing into the skin,
- measure both legs, because they can differ slightly, and use the measurement of the leg you want to wear the sleeve on.
Size chart for the KeenTrove knee sleeve
The measurement refers to the circumference of the thigh 10 centimeters (about 4 inches) above the kneecap:
- S: 32 to 39 cm (12.5 to 15 in)
- M: 40 to 47 cm (15.5 to 18.5 in)
- L: 48 to 55 cm (19 to 21.5 in)
- XL: 56 to 60 cm (22 to 23.5 in)
- 2XL: 61 to 66 cm (24 to 26 in)
- 3XL: 67 to 73 cm (26.5 to 28.5 in)
- 4XL: 74 to 82 cm (29 to 32 in)
Between two sizes?
If your measurement is right at the border between two sizes, most people are more comfortable with the larger one, especially if they want to wear the sleeve for many hours or at night. If your knee swells from time to time, measure when it is calm and choose the larger size rather than the smaller one. A sleeve should feel like a firm hug, not like a band that squeezes.
When the size is wrong
- the sleeve slides down or bunches up when you walk, which usually means it is too large,
- it pinches behind the knee or leaves deep marks, which usually means it is too small,
- you feel tingling or numbness, or the lower leg becomes cold or white, and then you should take it off right away,
- it is very hard to pull on, even when you roll it up first.
When the size is right, you hardly notice the sleeve during the day. For tips on when it helps most, read our article on when to wear a knee sleeve.
Frequently asked questions
Where do I measure for a knee sleeve?
Measure the circumference of the thigh 10 centimeters above the top edge of the kneecap, with the leg straight and relaxed.
What if I am between two sizes?
For all-day comfort, most people do better with the larger size. A sleeve should feel snug, not tight.
Should a new knee sleeve feel tight?
A new sleeve may feel firm when you first pull it on, but it should not pinch, leave deep marks or cause tingling. If it does, try a larger size.
