Learn how to hang a double hammock with straps in minutes. Follow these simple steps for a safe, comfortable setup every time.

Quick answer

Find two sturdy trees about 12–15 feet apart, wrap your straps around each trunk at the same height, attach the hammock carabiners, and adjust the tension for a gentle 30-degree sag.

Why double hammocks need extra care with straps

A double hammock is wider and heavier than a single, so the straps must be strong enough to support two people without stretching or slipping. The included straps on most double hammocks are designed for this, but you still need to check the weight rating and tree-friendly padding.

The 30-degree sag rule is even more important for a double hammock: too tight and you'll feel squeezed, too loose and you'll bottom out. Getting the angle right makes the difference between a relaxing hang and an uncomfortable one.

Choosing the right trees and strap height

Look for live, healthy trees at least 6 inches in diameter. Dead or damaged trees can drop branches or break under load. The distance between trees should be roughly 12–15 feet for a double hammock.

Wrap the straps at about chest height (around 4–5 feet up the trunk). This gives you enough room to adjust the hammock height once you sit in it. If the trees are farther apart, raise the straps slightly; if closer, lower them.

Step-by-step double hammock setup with straps

1. Find two sturdy trees: Locate two live trees about 12–15 feet apart, each at least 6 inches in diameter. Avoid trees with loose bark or signs of disease. Common mistake: using trees that are too close or too far apart. If the distance is under 10 feet, the hammock will hang too high; over 18 feet, the straps may not reach.
2. Wrap the straps around each tree: Pass the strap around the trunk at chest height (4–5 feet up). Thread the loose end through the loop and pull snug. Make sure the strap lies flat against the bark. Checkpoint: straps should be at the same height on both trees. A difference of more than a few inches will tilt the hammock.
3. Attach the hammock carabiners to the straps: Clip each carabiner onto a strap loop. Use the loop that gives you a gentle 30-degree angle when you sit in the hammock. For a double hammock, start with the outermost loops. Common mistake: clipping into the same loop on both sides. This makes the hammock too tight. Adjust one side at a time until the fabric forms a comfortable curve.
4. Test the tension and height: Sit gently in the center of the hammock. Your bottom should be about 18 inches off the ground. If you're too low, move the carabiners to a higher loop; if too high, move to a lower loop. Checkpoint: the hammock should sag about 30 degrees from horizontal. A good rule of thumb: the ridgeline (if present) should feel taut but not guitar-string tight.
5. Adjust for two people: If you're sharing the hammock, both people should sit at the same time before finalizing the strap loops. A double hammock will sag more with two people, so you may need to move the carabiners to a tighter loop than you used alone. Common mistake: one person sits first and the other climbs in later. This can cause the hammock to twist or dump the first person. Always adjust with both people in the hammock.
