Copula Size Guide
Copula Size Guide
Copula's size is its useful working length — the total of the two circumferences it can close around.
Buckle and overlap zones are already deducted: the number on the strap is the number you can use.
Three steps
- Measure both body parts exactly where the strap will sit — snug, not tight.
- Add the two numbers: A + B.
- Pick the size equal to or just above your sum. The closer the size is to your sum, the shorter the free tail and the cleaner the look.
| Size | Useful length (A + B) | Classic pairings* |
| Copula 40 | Up to 40 cm | Wrist + wrist · wrist + ankle |
| Copula 50 | Up to 50 cm | Ankle + ankle · wrist + biceps |
| Copula 60 | Up to 60 cm | Elbow + elbow · wrist + knee · ankle + biceps |
| Copula 80 | Up to 80 cm | Knee + knee · wrist + thigh · thigh + ankle |
| Copula 100 | Up to 100 cm | Wrist + waist · thigh + thigh |
* Examples only — the real number of combinations is far greater. Any two points of the body can be joined, and bodies vary far more than size charts: the same pairing can land in different sizes from person to person. Always measure your own circumferences and trust the sum, not the example.
Measuring points
Instep · ankle · calf · knee · thigh · waist · wrist · forearm · elbow · biceps.
Any two of them — one Copula.
Fit notes
- Measure in the position you plan to restrain in.
- Planning to wear it over clothing? Add 1–2 cm per body part.
- The right fit is snug, with one finger sliding under the band.
