How to Determine Your DonJoy® Knee Brace Size

Finding the correct size is one of the most important steps when choosing a DonJoy® knee brace. A knee brace that is too small may feel tight or restrict movement. A size that is too large may slip, rotate, or fail to give you the protection and stability you need. Learning how to measure your leg correctly ensures better comfort, better support, and the most effective performance.

This guide explains exactly how to measure your knee, thigh, and calf so you can select the right DonJoy® knee brace size. These steps match the instructions shown in the official sizing video and apply to most DonJoy® knee braces available on DonJoy® Store. Always review the sizing chart listed on each product page because different models can have unique requirements.

This short video demonstrates how to take accurate measurements at your knee center, thigh, and calf.

What You Need Before Measuring

• A flexible tape measure
  
• Bare skin or fitted clothing
  
• A stable, balanced stance

Stand with your legs shoulder width apart, knees slightly bent, and your leg muscles lightly contracted. This position helps you capture measurements that match how your leg behaves during movement.

Step 1: Measure at Knee Center

Locate the midpoint of your kneecap. Wrap the tape measure around your leg at this point and record the circumference. This is your knee center measurement and is often the most important factor when choosing your size.

Step 2: Measure Your Thigh

(6 inches above the center of your knee)

From the center of your kneecap, measure upward exactly 6 inches. At this point, wrap the tape measure around your thigh and record the circumference. This measurement helps determine how securely the brace will fit at the top.

Step 3: Measure Your Calf

(6 inches below the center of your knee)

From the midpoint of your kneecap, measure downward exactly 6 inches. At this lower point, wrap the tape measure around your calf and record the circumference. This measurement ensures your brace will stay in place during movement.

Compare Your Measurements to the DonJoy® Knee Brace Size Chart

Once you have your three measurements, compare them to the size chart for your specific brace model. Every product page includes the correct sizing chart with thigh, knee center, and calf measurements listed for each size.
