Clouds are building to the west, the rain’s an hour out, and in your pack there’s a square of fabric, six stakes, and a few yards of cord. With that, you can rig a dry, quiet shelter, or a sail that flaps all night over a damp sleeping bag. The difference isn’t the price of the fabric or how many knots you know: it’s the setup you choose for the weather, plus a few adjustments.
A A waterproof sheet with attachment points, set up with cord and stakes between trees or on poles to make a shelter. has no shape of its own: you give it one. British maker DD Hammocks says there are too many setups to list them all [1]. Four will get you through almost any night on the trail.
Which tarp setup for which weather
Three questions decide it: where’s the wind coming from, is the rain falling straight down or sideways, and what can you tie the tarp to? The diagram shows where each setup is anchored; the table sums up its strengths and limits.
| Setup | High points | In the wind | In the rain | Best for |
|---|---|---|---|---|
| A-frame | 2 trees or 2 poles, a ridgeline | Holds better when low | Both sides; the ends stay open | A night on the ground, or over a hammock |
| Lean-to | 2 poles or 2 trees | Low edge into the wind | One side only | Breaks, day shelter, a calm night |
| Diamond | 1 pole or 1 tree; 2 trees over a hammock | Low corner into the wind | Covers the ends too | A hammock in windy weather, a night on the ground |
| Closed | 1 pole about 3 ft (90 cm) tall, inside | Low and enclosed | Enclosed, door included | A rainy night on the ground |
| Flat roof | 4 poles, or trees | High, so exposed | Needs a slope to shed water | Shade, group shelter |
Based on DD Hammocks, Tatonka, Terra Nova, and the UK Scout Association. General trends: how well a setup holds depends mostly on tension and height.
The flat roof, fifth on the list, is mostly a fair-weather setup: four poles at the corners, two of them a bit shorter so water runs off if a shower blows through [2]. It’s a shelter for shade or for a group; a big 13 × 13 ft (4 × 4 m) tarp can even cover several hammocks at once [3].
A-frame: the classic, between two trees or two poles
It’s the most common setup, especially over a hammock, according to DD Hammocks [1]. A rope, the The rope stretched between two trees or two poles, from which the middle of the tarp hangs., runs between two trees; the tarp hangs from its center attachment points, then you stake out the four corners, plus the side points if needed [1]. Away from trees, two poles hold the ridgeline in place [4]. For the rope, Terra Nova suggests at least twice the length of the tarp [5], Tatonka 20 to 26 ft (6 to 8 m) [2].
An A-frame shelters both sides well, but both ends stay open. Its height is a trade-off: the lower it is, the better it handles wind, but the less room there is underneath, as Tatonka puts it [4]. The geometry shows what kind of room: on a 10 × 10 ft (3 × 3 m) tarp with its edges on the ground, a ridgeline at 3 ft (0.9 m) covers 7.9 ft (2.4 m) of ground, and one at 4.6 ft (1.4 m) just 3.5 ft (1.1 m). Drop the A-frame lower and you lose headroom, not ground.
Lean-to: quick to set up, sheltered on one side
A lean-to is a sloping roof: one edge staked to the ground, the other raised on a ridgeline or on poles [1]. It goes up in minutes, which makes it the go-to shelter for lunch and rest stops [1]; with a 10 × 10 ft (3 × 3 m) tarp, DD Hammocks says it can sleep up to three people on the ground [6]. Its weak spot: only one side is really protected [4].
With no trees around, Tatonka sets it up on two poles: the two corners on the windward side are staked to the ground, and each pole on the other side is held by two guylines pulled outward [2]. A trekking pole goes in tip up through the grommet, or handle first into the loop, where it holds better [2].
Diamond: for rain that blows in at the ends
The diamond is set up on a point, and only with a square tarp, DD Hammocks specifies [1]. Over a hammock, two opposite corners are tied to two trees or posts and the other two are staked to the ground: it’s the setup the maker recommends when wind drives rain in at the ends, and in very strong winds you can guy out more attachment points [1]. On a 10 × 10 ft (3 × 3 m) square, the diagonal, 14 ft (4.2 m), becomes the length of the shelter.
On the ground, one high point is enough: one corner tied to a tree or a pole, the opposite corner staked down [5]. Turn that low corner into the wind, like the low edge of a lean-to [4]. You end up with a pointed shelter, high at the entrance and closed at the back, where you sleep with your head at the high end.
Closed setup: the tarp that thinks it’s a tent
When rain settles in for the night, a tarp can close in on itself. The UK Scout Association describes this setup for a 10 × 10 ft (3 × 3 m) square with tie loops: it takes at least seven stakes, three guylines, and a single pole set to about 3 ft (90 cm) [7]. The two back corners are folded in and staked, the two front corners form the door, and the pole goes under the first center loop in from the entrance [7].
The closer together the two front corners, the narrower the door: brought together in the middle, they leave only a slit, and the shelter is closed [7]. A final guyline, tied to the center loop at the front, tensions the whole thing [7]. On soft ground, a small block of wood under the foot of the pole keeps it from sinking; and if the tarp isn’t reinforced at that point, a strip of gaffer tape keeps the pole from poking through [7]. DD Hammocks describes a version held up from inside by a trekking pole, or by a stick with padding on top [6].
Four more setups: flat roof, envelope, arrowhead, raised A-frame
The four basic setups cover most nights, but the same tarp can take plenty of other shapes. Australian gear maker Mountain Designs describes nine with a single tarp [9]; here are three of them, plus Tatonka’s flat roof, which the table above keeps for fair weather.
- Flat roof. Four poles at the corners, two of them slightly shorter on one side so water runs off, and eight guylines to tension everything. Tatonka suggests setting it up with a partner [2].
- Envelope. Two corners along the same edge are tied to two trees to form the top of a wall; the center points and the other two corners are staked down to make a floor. It’s a windbreak for warm but windy days [9], with no roof overhead.
- Arrowhead. The middle of one edge is tied to a tree and that edge’s two corners are staked; at the far end, you stake the center point and tuck the sides underneath. The shelter is low, streamlined, and holds up well in the rain, but it leaves no ground cloth to lie on [9]. Turn the low end into the wind, like the low corner of a diamond [4].
- Raised A-frame. The classic A-frame, but with its four corners held up by guylines instead of staked to the ground, so air flows underneath. The steeper the slope, the better the sides are protected; the flatter, the more room you have [9]. It’s the shape to set up over a hammock [1].
What keeps a setup up: tension, slope, height, orientation
A good setup doesn’t flap, doesn’t pool water, and doesn’t sag at 3 a.m. Four adjustments take care of that.
- Tension. First a taut ridgeline, then even tension all around: a slack tarp flaps in the wind and holds water. Nylon has a well-known flaw: it stretches when wet, even from dew, so a tarp pitched taut at bedtime can sag by morning [10]. Re-tension before you turn in, or add a short piece of shock cord to each guyline to take up the slack [10].
- Slope. Water needs a way off: no spot where it can collect [4], and a slope, however slight, toward an edge [2]. Your ground cloth shouldn’t stick out past the tarp, or it’ll catch the rain running off it [4].
- Height. High for the view, low for stability in storms, as Terra Nova sums it up [5]. The A-frame diagram shows it: every inch of height you gain costs you width.
- Orientation. The windward side close to the ground [4], and a spot picked before you unpack anything: no dead branches overhead, and no low spot between two rises, where cold air sinks and rainwater collects [7].
As for knots, Scout Life, the magazine of Scouting America, names three for guylines and tarps: the taut-line hitch, to adjust the tension on a guyline; the bowline, which forms a fixed loop for tying a line through a grommet; and two half hitches, for tying a rope to a ring or a post [11]. They’re best learned by practicing with someone who knows them, not from a page. Still, our guide to camping knots walks through the steps, the common mistake, and how to untie each one. Fishing line calls for other knots, which our fishing knots guide covers step by step.
With or without trees: where to tie the tarp
A living tree makes a great anchor, as long as you don’t damage it. Leave No Trace wrote its guidelines for hammocks, which pull much harder on a trunk than a tarp’s ridgeline does, so they apply all the more to a tarp [12]:
- a flat webbing strap at least 1 inch (2.5 cm) wide, wrapped once around the trunk, and never anything thinner, which damages the bark and the living layer just beneath it;
- never a nail or a screw driven into the wood;
- living trees at least 6 inches (15 cm) in diameter, with hard bark and no lichen, never a dead tree;
- a look up: a perfectly healthy tree can still hold a dead branch that’s ready to fall.
Add two common-sense rules: no notches cut into the wood, and no branches snapped off to make room. The best spot is one that already exists: good campsites are found, not made [12]. Some parks even ban hanging hammocks from trees; when in doubt, check with the land manager [12].
Without trees, a tarp goes up on whatever you have on hand: trekking poles, tarp poles, a fence or a post, and even, according to Tatonka, a bike or a canoe [2]. With no trekking poles, DD Hammocks suggests a sturdy stick with padding on top, so it doesn’t puncture the tarp [6]: look for one among the dead wood on the ground instead of cutting a living branch.
10 × 10 ft, 10 × 6.6 ft, or 13 × 13 ft: what each size can do
Size decides which setups you can use. The 10 × 10 ft (3 × 3 m) square is the jack-of-all-trades: it handles all four setups in this guide, and DD Hammocks considers it big enough for one person and their gear [6]. Rectangles, from 10 × 6.6 ft to 10 × 8 ft (3 × 2 m to 3 × 2.4 m), weigh less but work mainly as A-frames and lean-tos: the diamond is for squares only [1], and the Scouts’ closed setup calls for a 3 × 3 m tarp [7]. Set up lengthwise as an A-frame, a 10 × 6.6 ft tarp has only 3.3 ft (1 m) per side: at 2.6 ft (0.8 m) high, it covers 3.9 ft (1.2 m) of ground, enough for one sleeper. Terra Nova, for its part, suggests an 8 × 10 ft (2.4 × 3 m) tarp as a starting point [5].
| Size | Area | Setups | Published examples |
|---|---|---|---|
| 10 × 10 ft (3 × 3 m) | 97 sq ft (9 m²) | All four in this guide, diamond and closed included | DD Tarp 3x3: 28 oz (790 g), polyester; DD SuperLight, 10 × 9.5 ft (3 × 2.9 m): 17 oz (490 g), nylon |
| 10 × 6.6 ft to 10 × 8 ft (3 × 2 m to 3 × 2.4 m) | 65 to 78 sq ft (6 to 7.2 m²) | Mostly A-frame and lean-to | Terra Nova suggests 8 × 10 ft (2.4 × 3 m) to start |
| 13 × 13 ft (4 × 4 m) | 172 sq ft (16 m²) | All of them, bigger: group shelter, several hammocks | DD Tarp 4x4: 2.8 lb (1,290 g), polyester |
Weight of the tarp alone, without stakes or guylines, as listed by the maker. The three DD Hammocks models listed have a 3,000 mm waterproof rating.
Two details matter as much as size. Waterproofing: Terra Nova recommends a The height of a column of water, in millimeters, that a fabric can withstand before letting water through, measured in a lab. of at least 3,000 mm for rain [5]. And fabric: for almost the same area, the nylon SuperLight weighs 11 oz (300 g) less than the same brand’s polyester 10 × 10 ft tarp [6] [13], but it stretches when wet [10]. Ounce-counters have already made up their minds; just remember to re-tension before bed.
Where are you allowed to set up a tarp?
A tarp doesn’t change the law: where camping isn’t allowed, it isn’t allowed under a tarp either. The rules vary from place to place, and our European guides cover them country by country:
- backcountry camping in France, from beaches to national parks, with a note on Belgium;
- wild camping in Switzerland, canton by canton;
- wild camping in Germany, state by state;
- wild camping in the UK, from Scotland to Dartmoor.
One question comes up a lot: does a tarp count as a tent? The rules we’ve gathered talk about tents, camping, or bivouacking, almost never about tarps. The safest bet is to treat it as a tent, and to ask the landowner or land manager (town, park, public forest) before you unpack it. As for fire, it has no business under a tarp or next to one: the rules in France, which are strict, are in our guide to campfires in France, along with the Leave No Trace basics.

FAQ
What size tarp is best for solo backpacking?
A 10 × 10 ft (3 × 3 m) square is the most versatile: it handles the A-frame, lean-to, diamond, and closed setups, and covers one person and their gear. A rectangle from 10 × 6.6 ft to 10 × 8 ft (3 × 2 m to 3 × 2.4 m) weighs less, but is mostly for A-frames and lean-tos, and covers just one person. A 13 × 13 ft (4 × 4 m) tarp is mostly a group shelter.
How do you set up a tarp without trees?
With two trekking poles or two tarp poles: a pole goes tip up through the grommet, or handle first into the loop, and is held by two guylines pulled outward. The lean-to, diamond, and closed setups need only one or two high points. With no trekking poles, a stick of dead wood picked up off the ground, padded on top, will do the job.
What’s the best tarp setup for rain?
The closed setup protects best: a 10 × 10 ft (3 × 3 m) square on a pole about 3 ft (90 cm) tall, corners folded in, with a door you can close down to a slit. If wind drives rain in at the ends, the diamond covers them. Whatever the setup, keep the tarp taut and sloping, with no pockets where water can pool, and re-tension at night if it’s nylon.
Can you tie a tarp to a tree without damaging it?
Yes, with a flat webbing strap at least 1 inch (2.5 cm) wide, wrapped once around the trunk of a living tree at least 6 inches (15 cm) in diameter, with hard bark. Never a nail, a screw, or a notch, and never a dead tree. Look up for dead branches, and check with the land manager that it’s allowed.
Is it legal to sleep under a tarp in the woods?
Camping rules apply, and they change from one country, state, or even forest to the next. They talk about tents, camping, or bivouacking, almost never about tarps, so the safest bet is to treat it as a tent and ask the landowner or land manager. On BLM land, dispersed camping is allowed in most areas unless posted otherwise; our guides cover France, Switzerland, Germany, and the UK.
Tarp or tent: which is better for backpacking?
A tarp is lighter, more open, and can be set up in lots of ways, with or without trees; a tent is enclosed and takes less know-how. UK maker Terra Nova says that, with practice, a tarp will protect you in most spring and summer conditions in the UK. For winter and storms, a tent is still the simpler shelter.
