The butterfly coil is a method of carrying a rope used by climbers where the rope remains attached to the climber and ready to be uncoiled at short notice.

Another method of carrying a rope is the alpine coil.

"Static" ropes, used for example in caving, rappelling, and rescue applications, are designed for minimal stretch; they are not designed to arrest free falls.

The UIAA, in concert with the CEN, sets climbing-rope standards and oversees testing.

The current preferred international standard for rope sizes is to give the mass per unit length, in kilograms per metre.

However, even sources otherwise using metric units may still give a "rope number" for large ropes, which is the circumference in inches.

These ropes offer a greater margin or security against cutting, since it is unlikely that both ropes will be cut, but they complicate belaying and leading.

Ropes have tensile strength and so can be used for dragging and lifting, but are too flexible to provide compressive strength.

As a result, they cannot be used for pushing or similar compressive applications.

Rope is thicker and stronger than similarly constructed cord, string, and twine.

Rope may be constructed of any long, stringy, fibrous material, but generally is constructed of certain natural or synthetic fibres. Some ropes are constructed of mixtures of several fibres or use co-polymer fibres. Ropes have been constructed of other fibrous materials such as silk, wool, and hair, but such ropes are not generally available.

Climbing ropes, however, do cut easily when under load.
