How to Choose The Right Tarp Size For A-Frame?

April 5, 2026

Quick Answer

When choosing a tarp size for a shelter, you'll want to consider the number of people the tarp will need to accommodate, along with the desired floor space. A general rule of thumb is to choose a tarp that provides at least 7-10 square feet per person. This will give you enough space to move around comfortably.

Calculating Tarp Size for A-Frame Shelter

When it comes to creating an A-frame shelter, the tarp size will play a crucial role in determining the overall structure’s stability and functionality. To start, you’ll need to calculate the length and width of the tarp required. A good starting point is to use a tarp that is 12-15 feet in length and 7-9 feet in width. This will provide ample space for a small to medium-sized shelter.

Measuring and Cutting the Tarp

To create your A-frame shelter, you’ll need to carefully measure and cut the tarp to ensure a snug fit around your poles. When cutting the tarp, it’s essential to leave a 1-2 inch margin around the edges to allow for secure attachment to the poles. A tarp with a grommet pattern will make this process much easier, as you can simply pass the poles through the grommets for secure attachment.

Tips for Choosing the Right Tarp

When selecting a tarp for your A-frame shelter, consider the following factors: waterproof rating, durability, and material. Look for a tarp with a waterproof rating of at least 10,000 mm, as this will provide adequate protection from the elements. Additionally, choose a tarp made from a durable, water-resistant material such as nylon or polyester.
