Hammock Hang Calculator

Find hang angle and tree spacing for a hammock.

Distance between trees 8.66

Sag depth below trees 2.5

Formula: ridgeline = hammock × cos(angle); sag = hammock × sin(angle) ÷ 2

Step-by-step with your numbers:

1. Values used:

2. Hammock length = 10

3. Desired hang angle = 30 degrees

5. Distance between trees = 8.66

6. Sag depth below trees = 2.5

Find the tree spacing and hang depth for a comfortable hammock.

The math behind it

An ideal hang angle is ~30°. Ridgeline = length × cos(angle).

10 ft at 30° → ~8.7 ft trees, 2.5 ft sag.

Why 30°?

Shallower angles increase force on the anchors.
