The most common mistake people make when buying a compression sleeve isn't the brand or the material—it’s the size. In the world of orthopedic support, a "close enough" fit is actually a failure.
If your sleeve is too loose, it won’t provide the mechanical pressure needed to flush out inflammation. If it’s too tight, it can restrict blood flow and irritate nerves. To get the full benefits of Zenith Armour, you need a "Goldilocks" fit: snug, supportive, and perfectly aligned with your anatomy.
1. The Golden Rule: Measure, Don't Guess
Never choose your size based on your height, weight, or the size of your t-shirt. Your joint circumference is the only metric that matters.
How to Measure for a Knee Sleeve
-
The Position: Stand with your leg slightly bent (about 30°).
-
The Location: Measure the circumference around the center of your kneecap (the patella).
-
The Tension: Use a soft tailor’s tape. Pull it snug so there’s no gap, but don’t let it "dig" into your skin.

How to Measure for an Elbow Sleeve
-
The Position: Extend your arm fully and relax your muscles.
-
The Location: Measure around the thickest part of your elbow joint.
-
Pro Tip: If you have particularly large biceps or forearms, measure those areas as well. You want a sleeve that accommodates your muscle mass without cutting off circulation at the top band.

2. Navigating the Size Chart: "Tighter" vs. "Regular"
Most Zenith Armour products will place you in a specific category (S, M, L, XL). But what if you fall exactly between two sizes?
-
Choose the Smaller Size if: You want "Competition-Ready" support. This is best for heavy weightlifting or short, high-intensity sports where maximum stability is the priority.
-
Choose the Larger Size if: You want "All-Day Comfort." This is ideal for managing chronic pain, wearing at the office, or for seniors who need a support that is easier to put on and take off.
3. Measuring for a Waist Brace
The waist brace is unique because it relies on your navel circumference, not your pant size.
-
Measure around your torso at the level of your belly button.
-
Do this while standing and after a normal exhale (don't "suck it in").
-
If you are between sizes, we recommend sizing up. A waist brace that is too small will "roll" or pinch when you sit down.

4. The Ankle: Measuring the "Narrowest Point"
For the most effective ankle compression:
-
Measure the circumference of your ankle just above the "knobby" bone (the malleolus).
-
Also, take note of your shoe size. While circumference is the primary metric, shoe size helps ensure the heel-cup of the sleeve sits correctly.

5. Signs Your Fit is Perfect (The "Checklist")
Once your Zenith Armour support arrives, perform these three tests:
-
The Two-Finger Test: You should be able to slide two fingers under the top band. If you can’t, it’s too tight.
-
The Mobility Test: Can you fully flex and extend the joint? The sleeve should move with you, not act as a brake.
-
The Skin Test: After 30 minutes of wear, remove the sleeve. Light "fabric marks" are normal, but deep red welts or numbness in your fingers/toes mean you need to size up immediately.
Why Zenith Armour Sizing is Different
We use Anatomical Mapping in our weaving process. This means our sleeves are naturally tapered to follow the conical shape of your limbs (wider at the thigh, narrower at the calf). This design ensures that even if you are on the edge of a size bracket, the sleeve maintains its "stay-put" grip without excessive pressure.
