Should I consider the angle of my tarp shelter for drainage?

April 6, 2026

Quick Answer

Yes, consider the angle of your tarp shelter for drainage to ensure it remains dry and secure.

Importance of Tarp Angle

When setting up a tarp shelter, it’s crucial to create a slope that allows water to run off. A minimum angle of 20-30 degrees is recommended to ensure effective drainage. This angle also helps to prevent water from pooling and seeping into the shelter.

Calculating the Optimal Angle

To calculate the optimal angle, consider the type of tarp you’re using and the terrain you’re on. For a standard rectangular tarp, aim for a slope of 1:4, meaning for every 1 foot of rise, there should be 4 feet of run. Adjust the angle based on the tarp’s material and your local climate.

Setting Up the Tarp

To set up a tarp shelter with optimal drainage, start by staking down the corners and then attach the tarp to a nearby tree or pole. Use rocks or weights to secure the edges and ensure the tarp is tight. As you adjust the angle, use a level to ensure the tarp is level and the slope is consistent.
