    I'm fairly new at this, and I experienced the same issue. From what I've seen, the hang calculators out there are reasonably accurate for a starting point, but there is no way they can factor in the stretch of your specific hammock material or suspension. At 270 lbs, my HG single layer 1.6 stretches a lot. I just upgraded to a heavy double layer WB Blackbird, at this weight the few extra ounces justify the switch for structural stability.

    It's where the hammock CL attaches to strap, whoopie, etc connection at the hammock, not the tree.

    Yes, it works for just about any distance but you have to keep in mind that for closely spaced trees the suspension at the tree end will be attached much lower on the tree, and higher (and higher) up as the distance between trees increases.

    If you hang frequently enough in different places — as occurs when you do backpacking trips — you develop an "eye" and a "feel" for what will work and what won't. And you come to realize that things don't have to be perfectly centered (hammock and tarp between trees) and how to make some quick tweaks if things are off just a bit. And you learn that foot end higher by about 8" or so is better. Best thing is to get out in the local woods, if possible, and play with stuff.

    How did the hammock feel at that length?
    I haven't used the calculator previously, but I've just put my numbers in and the RL length shown, works out at 86.8% which I know wasn't the comfiest. Having tried between 80 and 90% I had settled on a RL that works out at 84%

    I think I'll stick to going by comfort for the RL and eyeballing the suspension.

    I've never tried a hammock calculator. Just always used trial and error.
    Have fun finding your sweet spot.

    When I first got into hammocking, I built a DIY stand based on a hang calculator. It got referred to here a lot, so that's what I went with. Instead of several feet of suspension, I ended up with several inches (to avoid a ridiculously low seat height). Learned an expensive lesson. But, it could be user error on my part, dunno. Good luck!

    As others have stated, the calculator doesn’t take into account materials being used. It assumes materials are fixed, where fabric and lines can produce wildly different results. You can’t rely on these for a proper hang.

    What you can rely on, is a tool for angle calculation, and a fixed or adjustable ridgeline to get a proper hang to match your desired seat height. Literally no two hangs will be the same, too many variables.

    A smarter calculator might take into account materials being used, which produce a ‘flex range’ that adds to the calculations, but man, what a crazy range that’d be.

    I’m game to try and build a calculator based off Dereks originally calculator if we could figure out the additional inputs (hammock fabric, suspension system/materials) or ability to put in fixed hardware measurements. Anyway, might be fun.

    In this matter, empiricism crushes science every time.

    I'm a bit confused about the photographs. The calculator says the sit height at 30 degrees should be 20 inches. To my eyes, that looks about right. The second one has a higher clearance but looks more like 20 degrees.

    I have noticed that once I set up my hammock, as soon as I sit in it the height goes noticeably down so if I don't remember to take this into account, I have to either change my angle or raise my anchor points.

    I too have found the calculator to be less than useful. No big deal when hanging outside on trees, but a bigger deal when screwing mounts to walls in the house. It told me to mount them at something like 66", but like you, the sag puts me practically on the floor. I wanted a 20" sit height.

    One of my brazilian hammocks came with instructions that seem more practical. It said to hang your hammock at a height half the distance you are spanning. Just a rule of thumb, but pretty good.

    My solution for indoors is to have a mount at the low end of the scale, say 66". Then mount a track, like the one Dutch sells, above that. That gives me slightly over a foot of vertical play, above the minimum offered by the calculator. If I had two trees the same distance as my walls, I would have simply gone and tried it out till I found what I wanted, but all my trees are further apart than my walls.


    Eta: Brazilian hammocks are of course designed to hang with more sag than a modern camping hammock, so you can lay more perpendicular to the ends and get flatter. I have found that depending on the camping hammock, this works well with them too, so again, just a rule of thumb. All my modern hammocks sag too much when going off the calculator, so they hang higher now as well.
