Quick Answer
The recommended height for a tarp ridge line is between 5-7 feet, depending on the type of tarp and the user's preference for ventilation and wind resistance.
Setting Up a Frame Tarp
When setting up a frame tarp, it’s essential to determine the ideal ridge line height to ensure a secure and comfortable shelter. A general rule of thumb is to use a ridge line height between 5-7 feet. This allows for adequate headroom while minimizing the risk of wind damage and rain entry. For a tarp with a width of 8-10 feet, a ridge line height of 5.5 feet is a good starting point.
Calculating Ridge Line Height
To calculate the ideal ridge line height for your tarp, consider the following factors: the length of your tarp, the width of your tarp, and the height of your tarp’s pole or ridge line attachment point. As a general guideline, the ridge line should be around 1/4 to 1/3 of the tarp’s length. For example, if your tarp is 9 feet long, the ridge line should be around 2.25 to 3 feet off the ground.
Adjusting for Wind and Ventilation
In windy conditions, it’s often beneficial to lower the ridge line to reduce the tarp’s surface area exposed to the wind. A lower ridge line will also improve ventilation and help to prevent the buildup of condensation inside the shelter. Conversely, in calm conditions, a higher ridge line can provide more headroom and improve the overall comfort of the shelter.
