Quick Answer
Different tarp shapes significantly impact wind resistance, with rectangular shapes generally being more stable than triangular shapes in high winds, and a square shape often providing the most resistance.
Choosing the Right Tarp Shape
When selecting a tarp for wind resistance, consider a rectangular shape with a length at least 1.5 times its width. This configuration provides greater stability and reduces the likelihood of the tarp folding or flipping in strong winds. A square tarp can also be effective, but its sides may not be as wind-resistant as a rectangular tarp.
Understanding Tarp Geometry
The angle of the tarp’s corners can greatly affect its wind resistance. A 45-degree angle is often ideal, as it allows the wind to flow over the tarp with minimal resistance. To achieve this angle, use a cord or pole to secure the tarp’s edges and create a consistent, smooth surface. A tarp with a flat or curved profile can also be effective, but may require additional securing measures to prevent flapping.
Securing the Tarp
To maximize wind resistance, ensure the tarp is securely attached to its anchor points. Use multiple stakes or anchors to prevent the tarp from shifting or lifting in strong winds. Consider using a tarp with built-in anchor points or clips to simplify the securing process. Additionally, use cord or rope with a diameter of at least 1/4 inch (6 mm) to prevent it from cutting into the tarp or anchor points under tension.
