Knee sleeve sizing

How to choose your knee sleeve size

Measure the knee joint itself. If you land between two sizes, take the larger.

How to measure

  1. Step 1 Measure

    Measure circumference of the knee joint with leg locked but relaxed. Adjust up or down for large or small calves.

    If your calf measurement is larger or smaller than your knee joint measurement, please use this measurement when choosing your correct size. Not your knee measurement.

  2. Step 2 Record

    Tighten the measuring tape so that it is snug, but not too tight. Record the measurement.

  3. Step 3 Pick a size

    Pick a sleeve size that fits your measurement.

We currently make knee sleeves from 9.6" to 20.1" around the knee (24.5–51 cm, 3XS to 3XL). If your measurement falls outside that, we do not make a sleeve for it yet — message us and we will tell you straight.

Not every colourway is made in every size. The size selector on the product page is the authority on what that particular pair comes in.

Between two sizes? Take the larger. Of 2,838 reviews, sizing errors run about evenly in both directions — but they are not equally survivable. Six customers described a sleeve they could not get on or that numbed the leg; none described the opposite. A slightly loose sleeve still trains.

The original illustrated guide
Stoic knee sleeve sizing guide illustration. Step 1, measure the circumference of the knee joint with the leg locked but relaxed, adjusting up or down for large or small calves. Step 2, tighten the tape so it is snug but not too tight, and record the measurement. Step 3, pick a sleeve size that fits your measurement. Tip: if your calf measures larger or smaller than your knee joint, use the calf measurement instead. Its printed chart lists seven sizes in centimetres: XX-Small 27.5 to 30, X-Small 30.5 to 33, Small 33.5 to 36, Medium 36.5 to 39, Large 39.5 to 42, X-Large 42.5 to 45, XX-Large 45.5 to 48.
This print starts at XX-Small and stops at XX-Large. It is missing both ends of what we actually sell — XXX-Small (24.5–27 cm) and XXX-Large (48.5–51 cm) are real sizes and are not on it. The chart above is the current one.
