Quick Answer
The ideal length for a ridgeline when building a tarp shelter is between 8 to 12 feet, allowing enough clearance for the tarp to be pitched with a comfortable sag and sufficient space for occupants. This range is suitable for most individuals and can be adjusted according to personal preference and environmental conditions.
Determining Ridgeline Length
When building a tarp shelter, the ridgeline length is critical as it affects the overall pitch and sag of the tarp. A ridgeline that’s too short will result in a tarp that’s too tight, while one that’s too long will result in a saggy tarp that may not provide the desired protection. A good starting point is to use a ridgeline that’s between 1.5 to 2 times the length of the tarp, measured between the attachment points. For example, a 9x9 foot tarp would require a ridgeline of around 10-12 feet.
Measuring and Adjusting Ridgeline Length
To determine the ideal ridgeline length for your tarp shelter, measure the distance between the attachment points where you plan to pitch the tarp. Take into account any obstacles or irregularities in the terrain that may affect the pitch of the tarp. If you’re using a pole or stick as a ridgeline, you can use a measuring tape or a piece of string to measure the length. If you’re building a ridgeline using cordage, you can use a method called “lashing” to create a secure and adjustable attachment point.
Pitching a Tarp with a Ridgeline
When pitching a tarp with a ridgeline, it’s essential to create a slope that allows for a comfortable sag. A good starting point is to create a slope of around 1:2 to 1:3, which means for every inch of height, the tarp should sag 2-3 inches. This will provide a comfortable and dry space underneath the tarp. To achieve this pitch, you can use stakes, rocks, or other anchors to secure the tarp to the ground, and adjust the ridgeline as needed to create the desired slope.
