Learn how to select the perfect tent footprint size for your Big Agnes tent. This guide covers measuring, matching, and buying tips to protect your tent floor.
When you invest in a quality tent, protecting it from the ground is essential. A tent footprint not only extends the life of your tent floor but also adds a layer of comfort and insulation. However, choosing the right size footprint can be tricky, especially with the variety of tent models available. In this guide, we'll walk you through how to select the perfect footprint size for your Big Agnes tent, ensuring a proper fit and maximum protection.
Big Agnes is known for its innovative tent designs, and many of their tents have specific footprints designed to match the floor dimensions exactly. Using the correct footprint is crucial because an ill-fitting one can cause water pooling or leave parts of the floor unprotected. Let's dive into the steps to find the right size.
Why Tent Footprint Size Matters
A tent footprint serves as a protective barrier between your tent floor and the ground. It prevents abrasions, punctures, and moisture from seeping through. The size of the footprint must correspond to the tent's floor plan. If it's too large, it can extend beyond the tent edges, allowing water to collect on the footprint and then flow under the tent. If it's too small, it leaves areas of the floor vulnerable to damage.
Big Agnes designs footprints specifically for each tent model, ensuring a perfect fit. For example, the Battle Mountain 2 Footprint is tailored to the Battle Mountain 2 tent. Using the correct footprint not only protects your tent but also allows you to pitch the tent with just the footprint and rainfly for a lighter 'fast fly' setup.
- A properly sized footprint prevents water pooling and floor damage.
- Using the manufacturer's recommended footprint ensures a seamless fit.
- Some tents allow fast fly setups with a footprint, saving weight.
How to Measure Your Tent Floor for a Footprint
If you're unsure about your tent's footprint size, you can measure the floor yourself. Pitch your tent fully, then measure the length and width of the floor from the inside, including the bathtub floor's vertical sides. It's best to measure in multiple places to account for any taper or irregular shape. Write down the dimensions and compare them to the footprint specifications provided by Big Agnes.
For example, the Tiger Wall UL2 is a popular ultralight tent. Its footprint is designed to match its unique floor shape. If you measure your tent floor and find it matches the published dimensions, you can confidently purchase the matching footprint. Remember that footprints are often slightly smaller than the floor to avoid extending beyond the edges, so don't be alarmed if the footprint is a bit smaller.

- Measure length and width at the widest points.
- Consider the floor's shape (rectangular, tapered, etc.).
- Compare your measurements with the tent's specifications.
Matching the Footprint to Your Tent Model
The easiest way to ensure a perfect fit is to purchase a footprint specifically designed for your tent model. Big Agnes offers footprints for many of their tents, including the Big House 6, Sheep Mountain 2, and Blacktail 3. Each footprint is cut to match the tent's floor exactly, with grommets and straps that align with the tent's poles and stakes.
For instance, if you own the Blacktail 4 - Vetiver, you'll want the footprint made for that model. Similarly, the Fly Creek HV 1 Carbon Footprint is tailored to the Fly Creek HV1 Carbon. Using the correct footprint not only protects your tent but also simplifies setup, as the footprint can be used alone with the rainfly for a lightweight shelter.
- Check the tent's product page for the recommended footprint.
- Footprints often have color-coded webbing to match pole attachments.
- Some footprints are included with the tent, but many are sold separately.
Tips for Buying a Footprint for Your Big Agnes Tent
When purchasing a footprint, consider the type of camping you'll be doing. For backpacking, weight is a critical factor. Ultralight footprints, like the Fly Creek UL Quilt (which is a quilt, not a footprint, but illustrates the lightweight approach), are designed to minimize pack weight. For car camping, a heavier, more durable footprint may be acceptable.
Also, consider the terrain. If you frequently camp on rocky or rough ground, a thicker footprint offers more protection. Big Agnes footprints are made from durable materials, but you can also use a ground cloth as a temporary solution. However, a custom-fit footprint is always the best choice for long-term durability.
- Weigh the footprint to ensure it fits your pack weight budget.
- For rocky terrain, opt for a heavier-duty footprint.
- Consider a footprint with reflective webbing for easy setup at night.
Choosing the right size tent footprint for your Big Agnes tent is straightforward when you know your tent's dimensions and use the manufacturer's recommended footprint. A proper fit ensures your tent floor stays protected, extending the life of your gear. Ready to find the perfect footprint?
