What’s the ideal shape for a survival tarp shelter?

Choosing the Right Tarp Shape

When selecting a tarp for emergency shelter, consider its shape. A flat sheet or rectangular shape is not suitable as it allows wind and rain to pass through easily. A diamond or triangular shape, on the other hand, provides excellent wind and rain protection. This is due to its pointed apex, which deflects wind and water, and its broad base, which distributes the force of the wind and rain.

Measuring and Cutting the Tarp

To create a triangular tarp shelter, you’ll need a tarp with a length of at least 6 feet (1.8 meters) and a width of 4-5 feet (1.2-1.5 meters). Measure and cut the tarp to the following dimensions: a 4-foot (1.2-meter) base, with a 2-foot (0.6-meter) wide angle on each side. This will give you a triangular shape with a 90-degree angle at the base and a 60-degree angle at the apex.

Setting Up the Shelter

To set up the shelter, find a suitable location with a relatively flat surface. Drive two stakes into the ground, one at the base of the triangle and one about 2 feet (0.6 meters) away from the base. Tie the tarp to the stakes using cordage, making sure the tarp is tight and even. Use additional cordage to create a ridgepole, running along the center of the tarp. This will provide additional structural support and help to shed water. Finally, add additional stakes and cordage to secure the tarp and keep it in place.
