- This circumference chart is directly linked by the exact Q-Lok ROM Wraparound page's Sizing Chart control.
- Only S through 5XL are included because those are the sizes listed for this exact model on the supplied page. The linked knee chart also has an XS row, but XS is not listed for this model and is not included here.
- The inch and centimeter ranges are reproduced separately from the original chart, not calculated conversions.
- Adjacent ranges share boundary values. The source provides no rule for shared boundaries or for measurements that fall into different size rows.
