Quick Answer
When choosing a tarp for survival, consider the space you need to cover, wind direction, and available space to anchor the tarp. A square or rectangular tarp is often the most versatile choice, while an A-frame or ridge tarp can provide better protection from wind. The size of the tarp should be sufficient to cover you and your gear.
Choosing the Right Tarp Size
When selecting a tarp, consider the floor space you need to cover. A general rule of thumb is to use a tarp that is 1-2 square meters (10-20 square feet) per person, plus additional space for gear and mobility. For example, a 2x3 meter (6.6x9.8 foot) tarp is suitable for a single person, while a 3x4 meter (9.8x13.1 foot) tarp is better for two people.
Tarp Shape and Wind Protection
A square or rectangular tarp is often the most versatile choice for survival, as it can be easily set up in various configurations. However, an A-frame or ridge tarp can provide better protection from wind, especially in exposed areas. To set up an A-frame tarp, attach the tarp to two trees or poles, with the ridge running parallel to the wind direction.
Anchoring and Staking
When anchoring a tarp, use at least two stakes per side, spaced about 1-2 meters (3.3-6.6 feet) apart. Use a ridge line or a center pole to stabilize the tarp and prevent it from sagging or flapping in the wind. For added security, use guy lines to attach the tarp to nearby objects, such as trees or rocks.
