Use wide tree straps, choose healthy trees 10 to 15 feet apart, and hang the hammock with a safe 30-degree sag.
Learning how to put up a hammock between two trees is simple when you understand spacing, tree health, suspension angle, and weight limits. I have set up hammocks in backyards, campsites, and wooded trails, and the same small mistakes appear again and again: straps placed too low, trees that are too far apart, and ropes that damage bark. This guide explains how to put up a hammock between two trees safely, comfortably, and with less trial and error.
What You Need to Hang a Hammock Between Two Trees
Before learning how to put up a hammock between two trees, gather the right gear. A hammock may look simple, but the suspension system carries your full body weight and any movement you create.
You will usually need:
• A hammock rated for your weight
• Two tree straps, preferably at least 1 inch wide
• Two carabiners or hammock-rated connectors
• A tape measure or measuring app
• A small step stool, if the trees are tall and the straps must sit higher
• A soft brush or cloth to check the bark and straps
Use tree straps made for hammock suspension. They are wider than thin rope and spread pressure across more bark. Thin cord can cut into tree tissue, especially when it is pulled tight or used for many hours.
Check the label on every part. The hammock, straps, and carabiners should each support your total weight. If two people will use the hammock, add both body weights and include the force created by movement. Never assume that a strong-looking carabiner is safe for climbing or hammock use unless it has a clear load rating.
Choose the Right Trees and Location
Good tree selection is the first major step in how to put up a hammock between two trees. Choose living, healthy trees with firm trunks and strong root systems. Mature hardwoods are often good choices, but the species matters less than the tree’s health and size.
Look for trees that:
• Have trunks at least 6 inches in diameter
• Show no large cracks, deep cavities, or loose bark
• Have no major dead limbs above the hammock
• Stand on stable, level ground
• Are far from roads, cliffs, rivers, fire pits, and power lines
Avoid dead trees, leaning trees, trees with mushrooms at the base, and trees with large hanging branches. A tree can look solid while having hidden decay inside. If you see fresh holes, soft wood, split bark, or a deep hollow, choose another location.
Also check the ground below you. A hammock may swing into rocks, roots, stumps, or sharp branches. When learning how to put up a hammock between two trees, many people focus only on the trees and forget that a safe landing area matters too.
Measure the Tree Spacing
Most gathered-end hammocks work well between trees that are 10 to 15 feet apart. The correct distance depends on the hammock length and the type of suspension system.
A simple rule is:
• Tree distance should be close to the hammock’s total length
• Add more space only if your straps are long enough
• Avoid stretching the hammock tight between the trees
A tight hammock creates more force on the trees, straps, and attachment points. It also feels less comfortable and can make you sit too low or too high.
Place the hammock so it forms a gentle curve. This curve is called a sag. A common target is a sag of about 30 degrees from each anchor point. In simple terms, the hammock should look more like a smile than a straight line.
Many hammock users find that the lowest point sits about 12 to 18 inches above the ground when the hammock is empty. Once you sit inside, it may drop lower. Adjust the height so your body does not touch the ground, but keep the hammock low enough for a safe exit.
Install the Tree Straps
The next stage in how to put up a hammock between two trees is placing the straps at the correct height. Wrap one strap around each tree, keeping it flat against the bark.
Start with the straps about 4 to 6 feet above the ground. This range works well for many hammocks, but your height, hammock length, and tree spacing may require adjustment.
Follow these steps:
-
Wrap the first strap around the tree.
-
Feed the strap end through its sewn loop or adjustment point.
-
Pull it snug without twisting the strap.
-
Repeat the process on the second tree.
-
Make sure both straps sit at a similar height.
The strap should rest flat. Do not bunch it into a narrow band, twist it, or place it over sharp knots in the bark. Keep the strap away from loose limbs and rough edges that could weaken the material.
Use only purpose-made hammock straps. Do not use vehicle tie-downs, climbing slings, plastic rope, or thin utility cord unless the manufacturer clearly approves them for this use.
Connect the Hammock to the Straps
Once the straps are secure, connect the hammock using the included carabiners or suspension hardware. The connection should be easy to inspect and should not rub against a sharp metal edge.
With most adjustable straps, you can change the height by moving the carabiner to another sewn loop. Make equal adjustments on both sides so the hammock stays centered.
Check the connection points carefully:
• The carabiner gate should close fully
• The hammock loop should sit inside the carabiner
• The strap should not cross over the carabiner gate
• No fabric should be trapped in a sharp or damaged area
• The suspension should not scrape against the tree
Do not use a basic keychain carabiner. It may look strong, but it is not designed to hold a person. Use hammock-rated hardware with a stated weight limit.
This is also where the answer to how to put up a hammock between two trees becomes practical: connect the hammock loosely, sit in it slowly, and adjust one side at a time. Your body weight will show whether the straps are too high, too low, or too far apart.
Set the Correct Hammock Sag
The right sag improves both comfort and safety. A hammock that is too tight can place extra force on the anchor points. A hammock that is too loose may sit on the ground or make it difficult to get out.
Stand back and inspect the curve. The center should hang lower than both ends, with a smooth, even shape. If one end is higher, adjust that side before climbing in.
Try this safe test:
-
Place one hand on each side of the hammock.
-
Pull gently to check for loose or damaged fabric.
-
Sit in the center while keeping one foot on the ground.
-
Shift your weight slowly.
-
Check that the hammock does not slide, twist, or drop too close to the ground.
