What is the ideal hammock hang angle?

The ideal hang angle is approximately 30 degrees from horizontal. This creates a comfortable, flat diagonal lay that prevents the banana curve. At 30 degrees, the hammock fabric cradles you without excessive pressure points or shoulder squeeze.

What is a structural ridgeline?

A structural ridgeline is a cord that runs between the two ends of the hammock above the fabric, set at 83% of the total hammock length. It ensures a consistent sag depth regardless of tree distance and makes hanging your hammock perfectly easy every time.

How far apart should the trees be?

For a standard 3m hammock, trees should be 3.5-5m apart. Too close and the hang angle becomes too steep (uncomfortable). Too far and the hammock stretches flat with high tension on the straps. The ideal distance creates a 30-degree hang angle.

How much weight can tree straps hold?

Quality tree straps are rated to 200-500kg. However, the force on each strap increases dramatically as the hang angle decreases. At 30 degrees, the force per side is roughly equal to body weight. At 5 degrees (nearly flat), it can be 6x body weight. Never hang nearly flat.

How We Calculate This

Hang Angle

Angle = arccos(Tree distance / Hammock length)

Ridgeline Length

Ridgeline = Hammock length x 0.83

Force per Anchor

Force = (Weight x 9.81) / (2 x sin(angle))

Lower angles dramatically increase anchor forces. Never hang below 15 degrees.
