The Figure 8 knot is strongest when tied in which configuration?

The Figure 8 knot is strongest when tied in which configuration?

• A. Inside bight
• B. Outside bight
• C. With a twist
• D. Double overhand

Answer: (A)

The key idea is how the rope bears the load when the knot is formed. Tying the figure-eight with an inside bight places the bend and the load path on the inner side of the knot, giving a clean, symmetrical seating of the rope around the twists. This distributes forces more evenly and avoids sharp, concentrated bends, so the rope resists slipping or slipping open under tension. An outside bight tends to create a less favorable load distribution, with sharper bends that concentrate stress and can loosen or bias the knot. Introducing a twist adds an extra turn that disrupts the intended geometry, making the knot less stable under load. The double overhand is a related but different knot configuration and alters how the rope grips and how easy it is to untie after loading. So, the inside bight configuration provides the most favorable load distribution and stability for the figure-eight, making it the strongest option.
