If you’ve ever ordered volleyball knee pads online and ended up with a pair that slides down every other rally, you already know why sizing actually matters. It’s not just about comfort. Knee pads that don’t fit right won’t protect you when you hit the floor for a dig, and they’ll drive you crazy during warm-ups. This guide walks you through everything you need to know to find the right fit.
Why Sizing Matters More Than You Think
A lot of players, especially newer ones, just grab whatever’s available or go by feel in the store. That works okay in person, but online it’s a bit of a gamble if you don’t know your measurements. Knee pads that are too small cut off circulation and feel tight after about twenty minutes of play. Pads that are too large bunch up behind your knee or slide down your shin mid-rally, which is annoying at best and a real distraction at worst.
The good news is that once you know your knee circumference and understand how brands size their pads, buying online gets a lot easier.
How to Measure for Volleyball Knee Pads
You only need a soft measuring tape (the kind used for clothing) and about two minutes. Here’s what to do:
Stand up straight with your leg slightly bent, the way it would be during normal athletic movement. Find the center of your kneecap. Wrap the measuring tape around the widest part of your knee, right across the middle of the kneecap. Write that number down in centimeters or inches, whatever the brand uses.
That measurement is your starting point. Most sizing guides you’ll find from knee pad manufacturers are built around this number.
Standard Sizing Across Most Brands
While sizing can vary a little by brand, here’s a general reference for how most volleyball knee pad sizes break down:
Small typically fits knee circumferences between 30 and 34 cm (about 12 to 13.5 inches). Medium usually covers 35 to 38 cm (roughly 13.5 to 15 inches). Large tends to fit 39 to 42 cm (about 15 to 16.5 inches). Extra-large covers 43 cm and up (over 16.5 inches).
If your measurement puts you right between two sizes, it usually makes sense to size up. A slightly larger pad is easier to adjust than one that’s digging into your knee after an hour of play.
Kids and Youth Sizing
Youth sizing works the same way, just with smaller numbers. Most youth sizes run from XS through M and are designed for knee circumferences between roughly 25 and 35 cm. If you’re buying for a younger player, still measure first. Kids grow fast, and what fit them in September might not fit in January. It’s generally better to buy the right size now than to buy big and hope they grow into it — a pad that’s too large won’t stay in place and won’t protect properly.
Sleeve vs. Strap Style: Does It Affect Fit?
Yes, a bit. Most volleyball knee pads are sleeve-style, meaning they slide on over your foot and sit around your knee. For these, the circumference measurement is what matters most. You also want to check the pad length. Some pads are longer and cover more of the shin, which some players prefer. Others are shorter and more compact. Neither is wrong, it just depends on your playing style and what feels comfortable.
Strap-style knee pads are less common in volleyball, but they exist. These usually have more adjustability built in, so sizing is less of an issue, but the circumference measurement still helps you pick the right base size.
Material and Stretch Affect Fit Too
The material a knee pad is made from changes how it fits in practice. Pads with a high spandex or lycra content will stretch and conform to your knee better. Foam and gel padding adds thickness, which can affect how snug the sleeve feels. If you’re between sizes and the pad you’re looking at has a lot of stretch in the sleeve, you can usually go with the smaller size. If it’s a stiffer material, size up.
This is worth keeping in mind when you’re comparing options across brands, because two pads labeled “medium” can feel pretty different depending on what they’re made of.
How a Well-Fitting Knee Pad Should Feel
When you put on a properly sized knee pad, it should feel snug but not tight. You shouldn’t feel any pinching or pressure. The center of the pad should sit directly over your kneecap without you having to adjust it. When you bend your knee fully, there should be a little give in the fabric but the pad shouldn’t slide. After putting both pads on, do a few squats or move around a bit. If they stay in place and you forget they’re there within a few minutes, you’ve got the right fit.
If the pad rotates to the side, slides down, or leaves red marks on your skin, it’s not the right size.
What to Do When You’re Between Sizes
This comes up a lot. Here’s a simple rule: if you’re between sizes and you play on hard gym floors, size up. The extra coverage is worth it when you’re taking dives on a wooden court. If you play mostly on sand or softer surfaces, you can go with the smaller size since the falls are less intense.
If you’re shopping from a brand that offers free returns, it’s also completely reasonable to order two sizes and keep whichever fits better. Several brands offer this.
Canadian Brands Worth Checking
If you’re shopping in Canada, Jumplete is one of the better options for volleyball-specific knee pads. They make gear specifically for volleyball players, not just general sports gear rebranded for volleyball. Their sizing guide is available on their product pages and their customer support is responsive if you have questions about fit. You can check out their knee pad lineup at jumplete.ca.
For sizing reference, their pads tend to run true to size, so your measured circumference should map pretty cleanly to their size chart.
Quick Sizing Checklist
Before you buy, run through this:
Measure your knee circumference at the center of the kneecap. Check the brand’s specific size chart, not just a generic one. If you’re between sizes, go up. Look at the material: high stretch means you can size down slightly, low stretch means size up. Try them on before a full practice if possible and do a few movements to check for sliding.
That’s really all there is to it. Sizing knee pads isn’t complicated once you have your measurement, but it does make a meaningful difference in how well they protect you and how much you notice them during play.
Measure around the center of your kneecap with a soft measuring tape while your knee is slightly bent. Use that circumference measurement to match against the brand’s size chart.
Size up in most cases, especially if you play on hard indoor courts. A slightly larger pad is easier to adjust than one that’s too tight.
Yes, they can vary. Always check the specific brand’s size chart rather than assuming sizes are universal across manufacturers.
They should feel snug but not tight, stay centered over your kneecap without sliding, and allow full knee movement without pinching or rotating.
