Knee Brace Size Guide

Why knee brace size matters

A knee brace only works while it stays in position. Too loose and it slides down the leg during walking, taking the hinges out of line with the knee joint; too tight and it restricts circulation and becomes impossible to wear for the hours a recovery plan requires. For ROM braces this matters double: the hinge stops only protect the knee if the hinge stays aligned with it. Three measurements prevent all of this — and prevent a return that hygiene rules would not allow once the brace is opened.

What you need

• A soft tailor's measuring tape (not a metal one)
• A chair — sit with the leg relaxed and straight out in front
• Shorts or thin clothing, so you measure close to the skin
• A helper if bending forward is difficult after injury or surgery

The three measurements

Write all three numbers down in centimetres. Compare them with the size chart on the product page — our stocked Adjustable ROM Knee Brace uses a standard adjustable adult fit with multiple straps, so your numbers mainly confirm suitability rather than pick between sizes.

Common sizing mistakes

• Measuring over trousers — adds several centimetres
• Pulling the tape tight or letting it sag — measure snug but not compressing
• Measuring at the knee crease instead of the three points above
• Ignoring swelling — a post-injury or post-surgery leg is larger; measure the leg as it is now
• Guessing from trouser size, height, or general build

When to ask for WhatsApp help

Send your three measurements on WhatsApp before ordering if any of these apply: significant swelling, post-surgical restrictions, thigh and calf falling into different size ranges, a very slim or large build, or a surgeon's brace prescription you want matched. Sizing confirmation before dispatch is free — an opened brace cannot be returned.
