Most of the Bar hammocks will fit in a 15 foot stand, except for the Large Playa which requires a 16 foot stand. Suspension length 105.5 cm According to the calculator, for the 30 degree angle with sit heights of 20â³, 24â³, & 28â³, the heights for hang points are 44.2â³, 48.2â³, and 52.2â³, respectively, with a -7.5â³ suspension. I’m not that heavy, just want it to be sturdy, and again be cautious with the building structure. Because it is outside the â hammockâ length, love this calculator. For example: all independent variables (those that can be selected) should be in RED: Be sure to check with the manufacturer first on how they make that claim. I have tried to adjust the actual distance between anchors (3.2) until I have the desired suspension length at one end 50cm. What about a hammock with spreader bars ? From the baseline, you could drop the head end lower, or raise the foot end higher as both achieve the same result. Please update this web page. Falling is so not on my list of things to do. I’m currently trying to hang a 13 foot (total length) Nicaraguan in that same span of 11 feet. If you need to save some space it will be enough to remove the hammock from its hooks. TO bad we cant adjsut that ð. I laid out the hammock on the ground to see where I needed the two pipes to be placed in order to hold the hammock at the right height and angle, knowing I could fine-tune the distance with a length of chain later. In my testing you can use the calculator but the hang point needs to lower about 12 to 18 inches lower than what is stated. I have a stupid question on Hammock length. Any idea of the length of hammock i can buy? This is sufficient for the type of activity in a hammock. I.e. With a hammock that has a clew, is it part of the hammock length, or suspension length? This calculator will do all the math for you so you get a perfect fit and safe mount. Indoors is fine. The package says 6ft hammock but when measured from loop to loop it is 8′. Hammock stands boast both ease and flexibility for hanging a hammock as they offer endless possibilities for where to place your hammock. OW! You are correct. You can always get a hammock stand if such a spread isnât available to you. Using the right type of anchor bolts for the material is key. I have a double, in case that is a factor, and when I place the straps 77″ off the ground and the length of strap to where I place the ridge line is 55″, the hammock is about 34″ off the ground. PS looking for the best anti mossie system in tropics ie what can I use to stop mossies coming up from underneath in warm environments? If you are looking for new features, I’d love to have that included! I doubt you would have gone to the trouble of making this site or paying a developer to create apps if it just didn’t work, but I can do better by eye than what this thing gives me. Remember, tan(30) = sqrt(3)/3. The wall also exerts force in the opposite direction in equal amounts. I assume the above only applies if the suspension length required is even at each ends, if not, the different heign anchor points are required…Correct? Ah! thank you for your calculator, it’s a really awesome tool to use. Length of the hammock only since the ridge line is typically connected from these two points. I can’t change the width of the span between poles. Amazon lists the hammock dimensions as 156 x 55 x 2 inches. Do you think this is possible? It will mean less hardware options, like the clinometer, but would mean less fiddling with the code. Finally the horizontal component can be obtained through multiplying the cord tension with the cosine of the angle, or by means of Pythagoras’ theorem. 2019 and can’t find the android version in Google Play. At the “magic” angle of 30 degrees the forces are equalized so you will see 100 lbs on EACH SIDE of the hammock suspension if there was 100 lbs in the hammock. If the stand were taller you could use it for both hammocks without changing the stand but simply changing the hang point. As for a good two person hammock, I suspect you are looking for something to hang in the backyard? Let me do some checking on that. We are both in our 70s and did not want to hit the floor. Otherwise neat and easy to understand calculator. I found that 70″ high got me closer to sitting height. | Hammock Centre, Relax 101 - Perfecting the Art of Hammocking - Nikki Fogden-Moore, https://www.amazon.com/gp/product/B00O80MROA/ref=crt_ewc_title_srh_1?ie=UTF8&smid=A2RQVBHNLKPEYG&th=1.

Strap length (includes rope and hardware): 66. I cover these in more detail in my book because they can all effect these variables. Any decent calculator app is going to have trig functions, so people can make these calculations. But if we do 12′ apart so a tarp can be used, then we will probably have to use the straps? Sorry, I’m a hammock newbie. I’ve removed that information from my site. Also forgot to ask, do you measure overall length and ridgeline length from the far end of each carabiner where it contacts your suspension lines? Dear Derek, your calculator is wrong: it’s missing a factor 2. The Apple/iOS version is available and works fine offline. For example, a small pebble that weighs a few grams can exert more force than its weight if it is swung in a circle, say, in a sling. Cheers, thanks for the work and the book!Fab. Yeah, those numbers aren’t adding up. I have a very cheap Ikea like hammock that I am hanging indoors. I went down to my subterranean laboratory and came up with some numbers. If I have a 11′ wall and I’m looking to hang a 7′ hammock for two people. If you made this page into a PWA, a user on Android, iOS, or even PC would have an option in their browser’s menu to save the app. Are you using a ridgeline? Bruce, thanks for asking. 1 about the anchors being under lateral (torsional) stress and either pulling out or breaking. I’m using the calculator in metric units, if there’s any difference. If the ropes hung down at 90-degrees (straight down), the only force would be vertical. Does the calculator only work if the hammock is slung exactly in the middle of the supports ? Yes, taking the hammock off center has a similar effect of hanging one end higher. In theory, a hammock strung perfectly horizontal (0-degree hang), the horizontal force would be infinite. The app’s static calculations cannot account for dynamic changes such as fabric stretch, flex in a stand, or variations from different suspension types. The suspension is what attaches to the hammock and spans and distance to the anchor point. I said, after I get in, the angle will increase to about 30! I went to downplay the hammock calculator from the Google Play Store and just about every review said it wasn’t working on their phone (I have a Nexus 5x, which a few said it wasn’t working on), giving it a 1.8 rating. ð. L = Suspension length Yes! Suspension Length [What length should the supplemental tension be?] It is critical to know how much room you have before selecting the hammock, as space requirements vary widely. Shortening one suspension length has a similar effect to raising one end higher than the other. The ridgeline is the cord that runs inside the bug net on the top where the pocket organizer lives. If you have a total of 250 pounds (occupant plus the hammock, suspension and any additional gear), that is the total gravitational force acting on all points in the system. Anyway thanks NIce, but i need to hang on a certain height. The web app works fine on mobile if one chooses “request desktop site” in the browser. The calculator helps with a starting point, but you can modify from there for sure. I do have plans to update this web version. Also, I haven’t even bought the hammock yet ð If we could put a scale under the rock while it were spinning in a circle it would register as being “heavier” than if it were just hanging straight down. Some of those hammocks can be as long as 14 feet or more. If you want to buy only one strut or make your own, just borrow the dimensions of the stand. If you hang a rope straight down and attach a weight, the main force applied is gravitational, and the scale would show a weight equal to the weight attached (+ accessories). Any suggestions?? Currently, the hang point is not editable because it is a result of the hang angle you want, the sit height, and the distance between anchors. If the hammock was being hung vertically by two ropes pointing straight up, the tension in each rope would be half the weight. What’s needed to get it to show that value? Start with those and then adjust. Seems there have been some issue’s with the android app. The link to the app in the Amazon app store is broken. New to the whole hammock thing but enjoying it so far. Derek Thanks I have a android phone and the app works great. I also plan this to be a comfortable 2 person hammock for lounging ( maybe the magic 30 degrees changes ?? ) Perhaps the problem is that the calculator does not consider a distributed load?? You should ask around. In my testing, I’ve found that longer, wider hammocks benefit from a deeper sag (about 45° or so) thus giving you a more dramatic diagonal. This is a great option for disbursing the weight across multiple studs. If you have a hammock stand that has a fixed height and length than you’ve already limited yourself on what hammock you can buy that will fit in that space. The height & distances would still be the same? When I’m using the metric mode, none of the forces are displayed/updated. Do you hang the eye-bolt higher on the foot end? Just bought the app. Thank you for all you do for the community!!!! Derek, great calculator. First of, so glad I found you Youtube channel and website! But let’s focus on the basics. You don't need too much space to hang a hammock in your apartment. I love the look of the Mayan Rada and am considering that with tree straps (which I am pretty confident will work on the brick columns (they are square, so will allow for easy wrapping). My rain fly is 10' ï¸10' larger enough to cover the hammock. Think when I did this the suspension length came out wrong. Often, I find myself trying to hang a hammock off-center – closer to one tree than the other. We either have to buy a hammock stand, or go some place where there are two trees properly distanced from one another to hang the hammock. The math is a bit different for me as well (I had help making it work). That’s really short. I’m thinking of creating an indoor hammock stand for a very small space, and the main detail I’m having some trouble deciding is at what height the hang points should be. A simple amazing little tip on how to tie up a Brazilian Hammock in a short space, that your hammock is almost or touches the ground or is brushing up against an object that makes it ⦠This throws some folks off because it doesn’t seem to make sense that if I weigh 100 units, each side of the hammock suspension is also bearing 100 units. So for a given load at the bottom aka hammock, the straps from the tree to the hammock ends, do they take the same load, or is the load split between them? Ahhh, so much better! Hammock tips, illustrations, and reviews. I hope this makes sense. ð I’m not a fan of these tippy contraptions and would prefer if the world was rid of them. This calculator could help with the […], […] As long as you keep to the ideal distance, you can set camp just about anywhere. Love it. You should be able to install it by downloading the apk from an alternate source, but may not work properly. then just calculate the ridgeline to be sit height + ridgeline height off the ground? While the diagram and calculator are helpful I would suggest using different color coding. If you punch in the numbers into the calculator, it should give you the hang point. R team indicated it was coming back. weight, ridge line, distance — in preference.and recalculate. Use as normal and remove the ridge line length. Given the same sit height for these different hammocks, you should have different hang points because the take off angle is different for each. Which means the only force it can transfer is tension. No worries! The minimum hang distance between anchor points is roughly 1 foot shorter than the hammock is long. What would be the formula / calculation to determine the tension on a fixed ridgeline? The calculation is more complicated than that. Trees, the traditional hammock hangers, must be spaced properly and large enough to support the hammock. Honestly, I haven’t had a chance to experiment. Yes, the calculator looks at straight lines. This is what I do in a few of my rooms to accommodate a few different hammocks and give me some flexibility. First is the weight, or the vertical force. I searched the spam folder too with no success. How much space do I need to hang a hammock? Dumb question, but I don’t see it answered anywhere in the app or online. Which means the gravitational force will be divided 50/50 over the two suspension cords, when the center of mass of the hammock plus its inhabitant(s) is exactly in the middle between the two suspension points. Should I chose “Hammock length” instead and measure from loop to loop (the loops at each end)? Let me know if you have further questions. This is why I encourage folks to hang their hammock at an angle. My Hennessy is only 9.5 ft long when laid down flat, but you’d have to detach the ridgeline in order to pull it out flat. Thanks for your efforts! I’ve bought the app and have a suggestion for the user interface – can you make the number boxes active so we can tap on them and change the number? Most 10×5 foot hammocks, common in camping, work with a 30° hang angle typically. Anyway, I’m sorry about the mixup. Hanging a hammock is apparently not as simple as I thought. I’ll look in to it. I bought your app and I got a question on a hennessey asym hammock isn’t the ridge line and hammock the same size? For a 45 degree angle, the respective hang point heights are 62″, 66″, & 70″, with a 3.4″ suspension. Find a space with a distance of about 112 inches between your two structures, where you can attach the anchors for the hammock about 50 inches off the ground. I just need some time. When I put in 15ft distance between anchors, Ridgeline and hammock length 100, preferred sit height 18, weight in hammock 170 lbs, thehang point says 41.1 inches. It would be just like they installed a simple app from the play store, but you wouldn’t have the maintenance nightmare of chasing new versions of iOS/Android. Too heavy for backpacking, but backyard hangs or car camping are perfect. You have been offered a refund. I would guess that would change the dynamics of the whole calculator if a fixed ridgeline is installed on the hammock. I have been camping as a ground dweller with the family. Love the calculator. 2 about the stress on the Victorian walls – presumably the mountings will fail before the walls do. Thanks again. It works great on laptops and desktops. (e in b)&&0
