How to Measurefor Your TrueDial
1
Why Fit Matters
Too loose, and it can't do its job
A brace that's too big slides and won't steady the joint
Too tight, and it becomes a distraction
Too small can pinch or affect circulation; comfort is what keeps it on
The TrueDial advantage
TrueDial adjusts with a dial, not fixed elastic — measure to land in the right size range, then dial in the exact tension.
2
What You'll Need
- Soft flexible tape measure (or string + ruler)
- Pen and paper
- The TrueDial size chart
Before you start
Measure on bare skin, leg relaxed, don't flex the muscle.

How to Measure Your Knee
TrueDial uses two simple measurements — around the knee and just above it. Measure each twice.
STEP 1 — "Around the Kneecap" (primary measurement)
Wrap tape around the widest part of the kneecap, snug not tight.
Tape around center of kneecap
STEP 2 — "Above the Knee" (for a secure hold)
Measure thigh 4–6 inches (10–15 cm) above the kneecap center.
Tape around thigh above kneecap
Take each measurement twice and average; if knees differ, use the larger; the dial tightens from there.

Choosing Your Size
Match your numbers to the TrueDial size chart.
📐 View Size Chart
| More compression and a firmer feel during activity | → the smaller size |
| More flexibility and all-day comfort | → the larger size |
Still unsure? Size up.
TrueDial tightens with the dial, so a slightly larger brace dialed in beats a too-small one.

Check the Fit Once It's On
After dialing to a comfortable tension, walk, sit, stand, bend the knee — it should stay put without pinching, kneecap centered in the opening.
Signs it needs adjusting
- Numbness, tingling, or a cold feeling in the foot or lower leg
- Skin discoloration above or below the brace
- The brace slides down while walking
- Increased pain or swelling with the brace on
- Fabric bunching or folding behind the knee

If the knee is actively swollen the reading may be larger; measure at a different time of day; this is general fitting help, not medical advice.
