Too short, and you’re unclipping the lanyard every time you use the thing it’s protecting — which means one day you won’t clip it back. Too long, and slack cord snags on everything. Getting the stretch length right is what makes a lanyard disappear into your workflow, and it’s a simple calculation.
The rule: anchor point to furthest task, plus margin
Measure from where the lanyard anchors (belt, chest, workstation) to the furthest point you use the item — the car door lock, the parcel on the far side of the bench, the card reader — and add a comfortable margin so the cord isn’t at full tension during normal use. A coil’s packed length is a fraction of its extended reach, so buy for the extended figure.
Typical setups
• Keys on a belt: standard coil stretch covers pocket-to-door comfortably — you should unlock car and front door without unclipping.
• ID badge at chest: short reach to the card reader; here retraction tidiness matters more than length.
• Hand tools at a bench: anchor at the workstation and measure the working sweep of the bench, not just arm’s length.
• Shared equipment across a workstation area: this is where extended-reach designs earn their keep — our longest builds stretch to around 300cm (roughly 118 inches), developed for delivery-station equipment that serves multiple positions from one anchor.
Coil diameter and cord gauge change with length
A longer stretch isn’t just more of the same cord — recoil behaviour depends on cord gauge and coil diameter, which is why very long designs are engineered rather than simply cut longer. When you order a custom length from us, we confirm the specification with our manufacturer before quoting lead times, so what arrives recoils properly at the length you asked for.
