Hammock & Hanging Tools & Calculators

Free, practical tools for hanging a hammock right — check your hang angle, cut a ridgeline to length, size your strap load, scout tree spacing, weigh your pack, and dial in the 30° comfort angle.

Hang Distance & Sag Calculator

Check the hang angle you'll actually get from the distance between your trees, your ridgeline length, and your strap height — and see if it lands in the 25-35° comfort band

Ridgeline Length Calculator

Work out how long to cut your hammock's fixed ridgeline from its body length — the 83% rule for a balanced lay, plus deeper or flatter alternatives

Strap Load Calculator

See the actual tension each suspension strap carries at your hang angle, and check it against a rated capacity — a flatter hang multiplies the load fast

Tree-Friendly Spacing Calculator

Scouting a campsite? Find the ideal distance between two anchor trees for your ridgeline length and reachable strap height, before you commit to a spot

Packed Weight Calculator

Add up your hammock, suspension, hardware, tarp, and insulation to see your total packed weight and where it lands against common weight classes

30° Comfort Angle Calculator

Planning a hang from scratch? Enter your tree distance and ridgeline length and get the exact strap height for the recommended 30-degree comfort angle
