Do I Need A Tarp Under My Tent?

You don’t really need to but it can be helpful to put a tarp under your tent. 

A tarp can provide an extra layer of protection against moisture, sharp objects, and other potential hazards that could damage your tent. 

It can also help extend the lifespan of your tent by preventing wear and tear on the bottom. You can read how long tents last here.

Benefits Of Using A Tarp Under A Tent

Protection For Your Tent

The number one reason why you should put a tarp under your tent is to protect the bottom of your tent and help it last longer. A tent is an investment, and using a tarp can help extend its lifespan. 

A tarp can reduce the friction between the tent and the ground and minimise the chances of the bottom of the tent getting ripped or torn from sticks or rocks. This can also help to prevent wear and tear on the floor of your tent, which is especially important if you are camping on rough or rocky terrain.

Improve Waterproofing

A tarp can also help to improve the waterproofing of your tent. When it rains, water can seep into the ground and through the bottom of your tent. However, a tarp can act as an additional barrier between your tent and the wet ground. 

It can also help to prevent moisture from getting inside your tent, especially if you are camping in an area with high humidity or dew. By using a tarp, you can stay dry and comfortable inside your tent even during wet weather.

Improve Insulation

Another benefit of using a tarp under your tent is that it can help to improve insulation. A tarp can provide an additional layer of insulation between your tent and the ground, helping to keep you warm and comfortable throughout the night. 

This is especially important if you are camping in colder weather, as it can help to prevent heat loss from the ground.

Create A Dry Area In The Porch Area

Another benefit of using a tarp under your tent is that it can create a dry area in the porch or vestibule of your tent. By placing a tarp slightly larger than the size of your tent footprint, you can create a covered area in front of your tent that can be used to store gear or to cook in inclement weather. 

This can be especially useful in wet conditions, as it provides a dry space for you to take off wet gear or to hang it up to dry. Additionally, having a covered area in front of your tent can help prevent dirt and debris from getting tracked into your living space, making for a more comfortable camping experience.

Cons Of Using A Tarp Underneath A Tent

Extra Weight

This may not be an issue if you are car camping but if you are backpacking or hiking to your campsite then carrying a tarp may be one of the non-essential items you may consider not taking. 

Tarps are often bigger and bulkier than a tent footprint. If you know the surface of your campsite won’t be rocky and rain isn’t forecast, you may decide you don’t need the extra weight and space that a tarp takes up.

Rain May Be Funneled Under Your Tent

If you don’t position the tarp correctly rain may run under your tent and soak into the floor of your tent. Tarps are often sold in standard sizing that may not fit your tent exactly. 

If there is any extra tarp sticking out and it rains the tarp can act as a funnel and water can accumulate under your tent. It is important it is sized appropriately as it isn’t sized perfectly for your tent like a tent footprint.

Alternatives To Using A Tarp Under A Tent

A tent footprint that is made to exactly fit underneath your tent is a great alternative to using a tarp. They are made to fit a specific brand and model. 

This is what we use for our family tent. It’s great because we don’t have to roll any extra tarp underneath and helps us position where we want our tent to go before setting it up.

A tent footprint is sometimes called a ground cloth or ground sheet. The dimensions are cut perfectly to fit the bottom of each tent so they fit really well.

Often the tent footprint will have eyelets that match up to the tent so they can be pegged down together.

They are also not as bulky as a tarp and roll up into a carry bag the size of a sleeping bag.

How To Setup Your Tarp

Step 1: Lay out the tarp on the ground.

Step 2: Position your tent on top of your tarp.

Step 3: Fold any extra tarp underneath your tent. If you fold it over instead of under it can create a water bucket. So this is very important to tuck it under and make sure none is sticking out. 

What Size Tarp For Under Your Tent?

Choosing the right size tarp for under your tent is important to ensure maximum protection and coverage. Generally, you’ll want a tarp that is slightly larger than the footprint of your tent. This will ensure that the tarp extends beyond the edges of your tent and creates a barrier between your tent and the ground. 

If the tarp is too small, it may not provide adequate protection or coverage, leaving the bottom of your tent exposed to potential damage or moisture.

On the other hand, if the tarp is too large, it can create a tripping hazard or collect rainwater, which can lead to pooling or flooding underneath your tent. 

Therefore, it’s recommended to measure the dimensions of your tent and add a few inches to each side to determine the appropriate size tarp for your needs.

Tips for Using Tarps in Camping Setups

  • Size of the tarp: Ensure that the tarp is slightly larger than the footprint of your tent.
  • Materials: Choose a tarp made of durable, waterproof materials to withstand harsh weather conditions.
  • Weight: Opt for a lightweight tarp to make it easier to carry and set up at your campsite.
  • Eyelets and attachment points: Look for tarps with reinforced eyelets and multiple attachment points for versatile setup options.
  • Extra pegs: Pack extra pegs to secure the tarp to the ground and prevent it from shifting or flapping in the wind.

Best Practices When Using Tarps With Tents

When using tarps with tents, it’s important to follow some best practices to ensure a safe and comfortable camping experience. 

First, ensure that the tarp is clean and free of debris before setting it up. This will help prevent damage to your tent and ensure that your camping area is clean and comfortable. 

When setting up the tarp, ensure that it is secured tightly to the ground with pegs or stakes. This will help prevent the tarp from flapping in the wind, which can cause damage to your tent or create noise that disturbs your sleep. 

Additionally, avoid setting up the tarp on sloped or uneven ground, as this can cause water to pool or flow underneath the tarp and into your tent. 

Finally, be mindful of the weather conditions and adjust the tarp as necessary to ensure that it provides adequate protection from wind, rain, and other elements. 

By following these best practices, you can ensure that your tarp provides the necessary protection and comfort to make your camping experience enjoyable and stress-free
