Learn how to select a tent footprint that fits your tent and protects your floor. This guide covers sizing, compatibility, and the trade-offs between custom vs. universal groundsheets.
Quick answer
A tent footprint should match your tent's exact floor dimensions and pole attachment points. A custom-fit footprint from the tent manufacturer costs more than a universal tarp, but it protects better and enables a fast-fly pitch.
Why a custom footprint outperforms a universal groundsheet
A custom tent footprint is precut to match your tent's floor shape and includes grommets or loops that align with your tent's pole clips or stake loops. This means the footprint stays tucked under the tent even in wind or on sloped ground. A universal tarp, by contrast, often extends past the tent walls or bunches up, letting water pool between the layers.
Another advantage of a manufacturer-made footprint is the ability to pitch a fast-fly shelter. For example, Big Agnes footprints let you set up the tent fly, poles, and footprint without the tent body, creating an ultralight tarp-like shelter. This is a useful option for fast-and-light trips when you want to save weight.
The trade-off: cost vs. versatility
Custom footprints typically cost USD 35–70, whereas a universal groundsheet or polycro tarp can be had for under USD 20. If you own multiple tents or plan to use the groundsheet for picnics or gear storage, a universal tarp is more flexible. But for regular camping with a single tent, a custom footprint is a better long-term investment because it extends the tent floor's life without adding excess material.
Size and compatibility: what to check before buying
The most common mistake is buying a footprint that is too large. A footprint that extends beyond the tent floor catches rain and channels it under the tent, defeating its purpose. Always check the footprint's listed dimensions against your tent's floor dimensions. For Big Agnes tents, the footprint model name usually matches the tent model (e.g., Blacktail 4 Footprint for the Blacktail 4 tent).
If you cannot find a custom footprint, look for a universal groundsheet that can be trimmed to size. However, trimmed edges may fray and no longer have reinforced grommets, so this works best for flat ground and calm conditions.
Decision rules for choosing a tent footprint
- Match the tent model exactly: Search for a footprint that shares the same model name as your tent (e.g., Fly Creek UL1 Footprint for a Fly Creek UL1 tent). This ensures the grommets and shape align with the tent's pole clips.
Fly Creek UL1 Footprint - Verify floor dimensions: Compare the footprint's listed dimensions to your tent's floor dimensions. The footprint should be slightly smaller than the tent floor to avoid catching water.
- Check for fast-fly compatibility: If the footprint is from a manufacturer that supports a fast-fly pitch (like Big Agnes), you can leave the tent body at home and use the footprint, fly, poles, and stakes for an ultralight shelter. This is a weight-saving trick for backpackers who want to shave ounces without sacrificing protection.
- Consider a universal tarp for multiple tents: If you own several tents or want a multi-use groundsheet, buy a large universal tarp and trim it to fit your biggest tent. Accept that it won't have grommets and may need staking separately. Universal tarps are cheaper but less secure in wind and on uneven ground.
Footprint models at a glance
- Blacktail 4 Footprint: The Blacktail 4 Footprint is designed to extend the life of your tent floor and enables a Fast Fly pitch using the footprint, tent fly, poles, and stakes. If you own a Blacktail 4 tent, this footprint gives you a second shelter option for weight-conscious trips.
Blacktail 4 Footprint - Sarvis VST 2 Footprint: The Sarvis VST 2 Footprint provides a protective ground cloth layer that shields the floor from abrasion, moisture, and wear during camping trips. This footprint is a straightforward way to protect your Sarvis VST 2's floor from sharp rocks and damp soil, keeping your tent in good shape longer.
Which footprint is right for you?
Best for
- Campers who own a single tent and want maximum floor protection and the option of a fast-fly setup
- Backpackers who prioritize weight savings and are willing to pay a premium for a custom fit
Not for
- Budget-conscious campers who need one groundsheet for multiple tents or occasional use
