Quick Answer
A minimum tarp size for a one-person shelter is approximately 7.5 to 9 square feet (0.7 to 0.8 square meters), with a tarp width of 6-8 feet (1.8-2.4 meters). This size allows for a simple lean-to or A-frame shelter. The tarp's dimensions will depend on the desired level of protection and comfort.
Choosing a Tarp Size
When selecting a tarp for a one-person shelter, consider the desired level of protection from the elements. A larger tarp provides better coverage and can be more comfortable, but it also adds weight and bulk to your pack. A smaller tarp, on the other hand, is lighter and more compact, but may not provide sufficient protection in harsh weather conditions.
Setting Up the Shelter
For a simple A-frame shelter, you’ll need a tarp with a minimum width of 6 feet (1.8 meters) and a length of 3-4 feet (0.9-1.2 meters). To set up the shelter, find two sturdy trees or poles and tie the tarp between them, using cordage or clips to secure the edges. The tarp should be pitched at an angle of about 30-40 degrees to ensure proper water runoff.
Additional Considerations
When choosing a tarp, consider the type of fabric and its waterproof rating. A tarp with a waterproof rating of 2,000 mm or higher is recommended for most outdoor applications. Additionally, look for a tarp with reinforced seams and a durable design that can withstand the elements and heavy use.
