Quick answer: Use a flexible measuring tape and follow the measurement location specified by the knee-sleeve manufacturer. Many sleeves are measured around the upper calf near the knee, but brands use different measurement points. Keep your knee slightly bent, record the circumference without pulling the tape tight, then compare it with that brand's current size chart.
Important: There is no universal knee-sleeve size chart. Always use the manufacturer's specified measurement location and current chart before ordering.
Knee sleeves are an essential piece of an athlete’s tool kit. When we’re maxing out a new back squat PR or pushing ourselves to an all-time best Fran time, you want to be able to rely on your gear.
When it comes to choosing the right knee sleeves; you want a pair that provides ample support without cutting off circulation or sliding down your leg.
No worries, we’ve got you covered!
Check out our easy 4-step guide to finding the right fit for you.
Easy 4-Steps to Measure for Knee Sleeves
1. Get a flexible measuring tape
Use a flexible fabric or tailor's measuring tape. If you don't have one, wrap a piece of string around your leg and measure the string with a ruler.
2. Bend your knee slightly
Measure with your leg relaxed and your knee slightly bent rather than fully flexed.
3. Measure at the location specified by the manufacturer
Wrap the tape around the exact point specified by the brand. Some manufacturers measure around the upper calf below the kneecap, while others use the kneecap or another nearby point. Keep the tape flat and snug without compressing the skin.
4. Compare your measurement with the brand's size charts
Use the current size chart for the exact sleeve you're considering. Sizing and measurement locations vary by brand and model, so don't assume one brand's measurement translates directly to another.

What If I’m Between Knee Sleeve Sizes?
If your measurement falls between sizes, check the manufacturer's fit guidance first. A smaller size generally creates more compression, while a larger size may be easier to wear for longer sessions. Don't automatically size down unless the brand recommends it for your intended fit.
Should I choose 5mm or 7mm?
Knee sleeves are available in two thickness options – 5mm and 7mm.
Each is designed for a different purpose:
- 5mm – provides support while maintaining agility for WODs and metcons
- 7mm – heavier protection for shorter, heavier lifting
If your primary goal is protecting your joints while pushing for heavy Olympic lift PRs, the 7mm might be your best choice. 5mm knee sleeves are a thinner material best designed for metcons and dynamic movements. If you want to add some knee stability while focusing on your daily WOD, 5mm is the way to go.
Still Not Sure?
Maybe your measurement is between sizes, or you’re not sure to pick 5mm or 7mm.
