When it comes to protecting your tent and sleeping system, one often-overlooked piece of gear is the groundsheet or tent footprint. While these might seem like optional extras, they can play a crucial role in extending the lifespan of your tent, improving comfort, and protecting you from the elements.
In this article, we’ll explore the differences between a groundsheet and a tent footprint, explain when you need one, and help you decide which option is best for your Australian adventures.
What is a Groundsheet?
A groundsheet is a layer of fabric or tarp material placed under your tent to protect it from abrasion, moisture, and sharp objects on the ground. It acts as a buffer between the tent floor and the ground, preventing wear and tear and adding an extra layer of insulation.
Benefits of a Groundsheet
- Protection from damage: Sharp rocks, sticks, or uneven ground can puncture or wear down your tent floor. A groundsheet acts as a protective layer, keeping your tent floor intact for longer.
- Moisture resistance: Wet ground can seep into your tent, leading to discomfort and potential damage to your gear. A groundsheet helps keep the moisture at bay.
- Insulation: A groundsheet provides additional insulation from the cold, especially in damp or cold climates like Australia’s alpine regions or rainforests.
What is a Tent Footprint?
A tent footprint is a piece of material designed specifically to fit the exact dimensions of your tent. Most tents come with a footprint or recommend one as a compatible accessory. It’s usually made of a durable, water-resistant material and offers the same benefits as a groundsheet, with some added advantages.
Benefits of a Tent Footprint
- Custom fit: A footprint is designed to match the size and shape of your tent, offering tailored protection for your tent floor.
- Lightweight and compact: Tent footprints are usually made from lightweight materials, making them easy to pack and carry without adding significant weight.
- Durable: Footprints are made from high-quality materials, often with reinforced edges, making them more durable than standard groundsheet options.
- Easy setup: Footprints can make setting up your tent easier, as they are typically designed to be used with the tent poles and stakes, creating a seamless base layer.
Practical Materials for Groundsheets and Tent Footprints
Not all groundsheets are created equal, and material choice matters, especially if you’re trying to keep pack weight and bulk under control. While purpose-built tent footprints are convenient, many hikers use lightweight alternative materials for groundsheets or custom footprints with excellent results.
Common lightweight groundsheet materials
- Tyvek: A popular choice among hikers due to its excellent durability-to-weight ratio. It’s waterproof, abrasion resistant, and surprisingly tough for its weight. When cut slightly smaller than your tent floor, Tyvek makes an effective long-term groundsheet.
- Polycryo (window insulation film): Extremely lightweight and compact, making it appealing for ultralight hikers. However, it is far less durable than Tyvek and is best suited to short trips or careful campsite selection.
- Lightweight tarp material: Some hikers repurpose thin silnylon or PU-coated tarp material. This can work well if cut to size, but weight varies significantly depending on fabric choice.
Materials to avoid
- Building insulation products: Materials like Sisalation or foil-backed building wraps are not designed for repeated folding, abrasion, or outdoor ground contact. They tend to tear easily, degrade quickly, and offer poor durability for hiking use.
- Heavy plastic sheeting: While cheap and waterproof, it is bulky, noisy, and often heavier than purpose-built alternatives.
Choosing the right material comes down to balancing durability, weight, and how often you camp. For frequent hikers, Tyvek offers one of the best long-term compromises. For occasional or ultralight trips, thinner materials may be acceptable if used carefully.
Groundsheet vs Tent Footprint: Which is Right for You?
When deciding whether to use a groundsheet or a tent footprint, there are several factors to consider, especially in the context of Australian hiking.
1. Tent Type
- Freestanding Tents: If you’re using a freestanding tent, a footprint will help protect the tent floor and keep it in good condition. It also helps with quicker setup and stability.
- Non-Freestanding Tents: Non-freestanding tents are more exposed to ground damage, and a groundsheet can be used underneath for additional protection.
2. Terrain and Environment
- Rocky or rough ground: If you’re camping on rocky or uneven terrain (common in Australia’s Outback or desert regions), a footprint or groundsheet will protect your tent from damage due to sharp objects.
- Damp or wet conditions: For coastal or rainforest hikes, such as in Queensland or Tasmania, moisture protection is crucial. Both a footprint and a groundsheet will help keep the tent dry and reduce the chances of moisture seeping through.
3. Weight and Packability
- Ultralight hikers: If you’re trying to minimise pack weight, a groundsheet may be a more minimalist option, especially if you’re using a custom tarp or lightweight plastic material.
- Comfort-oriented campers: If you’re camping for a longer period in a high-use area, like a base camp or car camping location, a tent footprint will provide more tailored protection and be easier to manage with your tent setup.
4. Tent Size and Usage
- Single vs. multiple tents: If you only use your tent occasionally or for shorter hikes, a basic groundsheet may be sufficient. If you are regularly camping for extended periods, investing in a tent footprint can offer more long-term protection and convenience.
How to Use a Groundsheet or Tent Footprint
1. Placement
- Always ensure that your groundsheet or footprint is slightly smaller than the tent to prevent water from pooling underneath. If it’s too large, water may collect on top of the groundsheet and seep into your tent.
2. Stakes and Setup
- For footprints, simply lay it down before you set up your tent. Stake it down along with the tent to ensure it stays in place and provides maximum protection.
- For groundsheets, you may want to fold the edges under your tent or adjust the fit depending on the weather conditions.
3. Cleaning and Maintenance
- After each use, clean your footprint or groundsheet of any dirt, debris, or sand. Make sure it’s completely dry before storing it, especially if you’ve used it in wet conditions. This helps prevent mildew buildup.
Is a Groundsheet or Tent Footprint Necessary?
The short answer: Yes, but it depends on your hiking style and the conditions you plan to hike in. If you’re trekking through rugged terrain or moist environments in Australia, using a footprint or groundsheet will help preserve your tent and improve comfort. For ultralight hikers, carrying just a basic groundsheet made from light tarp material may be the most efficient choice. For longer trips in harsh climates, especially in places like the Snowy Mountains or Blue Mountains, a tent footprint may be the best option.

I have a footprint, but I prefer a sheet of tyvek. I find it tougher against tree roots/rocks, etc.
Ali Ayers me too. One of my tent footprints was a sheet of tyvek. I thought it was so good that I bought a roll and cut footprints for my other tents.
Ali Ayers Oh this is awesome advice!
Hi Darren
Thanks again for your thoughtful advice.
I have often wondered about the trade-off between having a heavier, durable built-in floor with good waterproofness head rating, rather than having a thin, more permeable floor which requires a footprint or groundsheet. I realise that much of this is about selling tents with low headline weights, but if the tent needs an additional layer beneath, this should really be included in the advertised weight.
For the buyer, the floor will be just one consideration and often not the primary one. With many tents, as you say, a footprint or groundsheet is probably essential.
I am guessing that tent floor durability has generally decreased as the trend has been towards lighter gear. Until 20-30 years ago, I think few of us used a second layer under the tent. I never considered it for my 1990s Macpac Olympus, which (I think) had a 20 000mm head.
I remember reading of one industrious fellow who replaced the floor on his Durston tent with what he felt was a more suitable fabric.
Cheers

Jonathan Miller that’s a really good observation, and you’re exactly right to frame it as a trade-off rather than a simple “better vs worse” decision.
Modern tents have largely shifted toward lighter floor fabrics to reduce overall pack weight, but that does push some of the durability and protection responsibility onto the user. In many cases, the footprint or groundsheet is effectively restoring what used to be built into the tent floor itself.
You’re also right about advertised weights. From a practical point of view, if a tent realistically needs a footprint in the conditions you’re using it in, then that should be considered part of the “true carry weight”, even if it’s not marketed that way.
The older tents you mentioned, like the Macpac Olympus, were built very differently. Heavier fabrics, higher hydrostatic head ratings, and more tolerance for rough ground. The trade-off was weight and bulk, but they were far more forgiving of poor site selection.
What’s changed isn’t just materials, but expectations. Lighter gear assumes a higher level of decision-making in the field: better site selection, more awareness of ground conditions, and an understanding of how small choices (like where you pitch) affect long-term wear.
That example of someone replacing the floor is interesting, and it speaks to the same point. People are trying to rebalance durability and weight based on how they actually use their gear, not just how it’s designed.
There’s no single right answer here. It really comes down to how much margin you want built into your system versus how much you’re willing to manage through your decisions on the trail.
Cheers,
Darren
I have tyvek.
if you wash it a few times in the washing machine the noise goes away and it gets nice and soft but doesn’t lose it’s strength
