The ideal hang angle is 30 degrees from horizontal. This creates the right amount of sag for a flat, comfortable lay while keeping strap forces reasonable. Steeper angles (40°+) create a banana shape; shallower angles (<20°) put excessive force on straps and trees.
| Hang Angle | Comfort | Strap Force (per side) |
|---|---|---|
| 15° | Too tight | 2x body weight |
| 30° | Optimal | 1x body weight |
| 45° | Too saggy | 0.7x body weight |
Strap length depends on tree distance and hang height. For typical 12–18 ft tree spacing with a standard 11 ft hammock, straps should be 4–8 ft each. Bring straps that are at least 10 ft long for flexibility with different tree spacings.
A structural ridgeline connects the two ends of your hammock at a fixed length (~83% of hammock length). It maintains consistent sag regardless of hang height or tree distance, making setup faster and more consistent.
Sit height should be chair-height: 16–20 inches off the ground. The attachment points on the tree will be higher than sit height because of sag. For a 30° hang angle, attach straps roughly 5–6 feet up the tree for a comfortable sit height.
