Freestyle OA — thigh and lower-leg circumference
Measurement: Circumference measured 6 inches (15 cm) above mid-patella and 6 inches (15 cm) below mid-patella. The original manufacturer chart publishes both inch and centimeter ranges.
| Size | Size suffix | 6 inches above mid-patella (in) | 6 inches above mid-patella (cm) | 6 inches below mid-patella (in) | 6 inches below mid-patella (cm) |
|---|---|---|---|---|---|
| S | X = 2 | 15–18 | 38–46 | 12–14 | 30–36 |
| M | X = 3 | 18–21 | 46–53 | 14–15 | 36–38 |
| L | X = 4 | 21–24 | 53–61 | 16–18 | 41–46 |
| XL | X = 5 | 24–27 | 61–69 | 18–20 | 46–51 |
| XXL | X = 6 | 27–30 | 69–76 | 20–22 | 51–57 |
- Both published units are transcribed as printed, not recalculated conversions.
- The original chart lists M below-patella circumference as 14–15 inches (36–38 cm) and L as 16–18 inches (41–46 cm). The intervening gap is retained without interpolation.
- Some adjacent ranges share boundary values. The manufacturer chart supplies no boundary-priority rule.
- The exact product page lists medial-left, medial-right, lateral-left and lateral-right configurations and provides one Freestyle OA chart; no separate configuration-specific ranges are published there.
- This chart is for Freestyle OA, not the next-generation Freestyle Plus OA.
