Hammock Setup Tips
Choose Strong Anchor Points
Look for healthy trees 12-17 feet apart with trunks at least 6 inches in diameter. Avoid dead or diseased trees.
30° is the Sweet Spot
A 30-degree hang angle provides the best balance of comfort and structural forces. Taller people often prefer 25°, shorter people 35-40°.
Level the Ends
Hang both ends at the same height relative to each other, not the ground. This prevents sliding to one side.
Sleep Diagonally
Lay diagonally across the hammock instead of straight down the middle for a flatter, more comfortable position.

Understanding Hammock Physics
The Science Behind the Hang
Hammock hanging involves careful balance of forces, angles, and geometry. The hang angle directly affects both comfort and the forces exerted on anchor points.
Force Distribution
- •Vertical Force: Always equals half your body weight
- •Horizontal Force: Increases dramatically as angle decreases
- •Total Tension: Combination of vertical and horizontal forces
Key Measurements
Height above ground where suspension attaches
Length of straps/rope from anchor to hammock
Straight-line distance between hammock ends
Vertical drop from ridgeline to lowest point
Pro Tip
The ridgeline is typically 83% of the total hammock length. This ratio helps maintain optimal shape and comfort across different hang angles.
