The other specifications are almost the same. You would get rainwater safety up to 1000mm. 210D Oxford polyester fabric is another similarity the tarps share among themselves.

The final item we have to throw into the mix is the BUFF SPORT Camping Tarp.

We are impressed with its sturdiness and performance.

The toughness of the BUFF SPORT Camping Tarp makes it eligible for a variety of uses.

How To Buy The Best Tarp For Under Tent?

Even though we are talking about the best tarp for under tent in this article, you should consider other possible applications while buying a tarp. Prioritize the under tent mat attributes and look at other features that make the tarp a genuine multifaceted one.

So, here are the factors you need to be mindful of-


You would be using the tarp to keep your tent floor safe or protecting yourself from weather adversities. That’s why you need a heavy-duty tarp. The ideal pick would be a tent that is not overly heavy to maneuver but has what it takes to successfully tackle weather extremities, rocky terrains, and wet campsites.

We have found that the denier count of 210 finds the right balance between low-weight and ruggedness. So, we would encourage you to go for a 210D fabric. A 210D fabric tarp paired with polyurethane or polyethylene coating should give you ample protection from all the previously mentioned problems.


 How much should you spend on the best tarp for under tent? You can find a lot of options below the $20 mark, but are they worth buying? We have reviewed a handful of tarps priced within that margin, and we can assure you that they can outperform some of their more expensive counterparts.

Within the said price bracket, you can expect a substantial degree of water resistance, something along the lines of 2000mm-3000mm. If you are paying over $20, you should demand an even higher water resistance rating. Aluminum grommets are fine, but you must look at stainless steel or brass if you are paying premium prices.


Size is an important consideration too. If you are buying a tarp as the ground cover for your tent, you would need to buy a tarp that covers your entire tent base. Don’t buy a tarp that is significantly larger than your tent floor. When you use a larger tarp, the rainwater will pool on the uncovered area, and eventually, the water might make its way into the tent.

So, pay close attention to the dimensions of both your tent and the tarp before buying an under tent tarp. Apart from the original size, also check how compact the tarp becomes when you fold it and pack it up for a trip. A tarp that occupies minimal space on the go is always a desirable purchase to make.

Reinforced Seam & Edges

Quality material will not suffice if the seam of the tarp does not come with extra protection. You would want your tarp to have subsidiary security measures for the sake of a prolonged lifespan and damage impunity. The corners of the tarp are particularly vulnerable to abrasion, so these areas should have multi-layer sewing.

Without reinforcement, the tarp will degrade at an accelerated rate. The water resistance tends to wear off with use. So, thin tarps are prone to becoming increasingly leaky as they pick up more mileage. Moreover, tarps with non-reinforced seam and corners don’t fare very well as windbreakers.

Tent Footprint Vs. Tarp: Is There A Difference?

Newbie campers might mistakenly think that tent footprint and tent tarps are interchangeable terms. While both of them could be used as tent floor guards, they are far from the same thing. We will draw an obvious line between the two, but first, let us tell you in brief why it’s necessary to use a tent floor guard.

Why Do You Need Tent Floor Protection?

Manufacturers are well aware of the fact that the tent floor goes through a lot of abuse outdoors. For that reason, they always try to make the base as robust as possible. But, price constraints and the urge to make tents lighter often make that a challenging endeavor. The result is an attempt to find the perfect mix of cost-effectiveness, sturdiness, and portability.

So, it’s not possible to make an indestructible tent floor. No matter how deliberately the tentmakers try to make the tent floor long-lasting, the roughness of camping sites and inhabitant weight take a toll on the floor. Gradually, the floor deteriorates and starts showing evident signs of ravages of time.

Here’s where tent footprints and tarps come in. Deploying a footprint or a tarp underneath the tent would ease off the pressure on its floor. Since the floor will no longer be in direct contact with the ground, it will not get rip and tears quickly. Floor protection would save the floor from moisture and levels the sleeping area in uneven terrains.

What Is A Tent Footprint?

It is a piece of clothing that campers use under tents. You can buy footprints for specific tent models or can make them yourself. All you need to do is to cut the cloth per the dimensions of the tent floor. It acts as a barrier between the floor and the campsite ground.

In doing so, the footprint keeps the tent floor safe from the earth’s harshness and humidity. Both factors accelerate the manifestation of wear and tear in tent floors. You can choose any waterproof fabric to make a tent footprint. A tent footprint serves no other purpose than protecting tent floors.

What Is A Tarp?

A tarp, on the other hand, is a piece of multifunctional camping equipment. Tarps are sheets of fabric as well. But, they have several applications besides tent floor protection. You can use a tarp as a picnic mat, a hammock, a canopy, or a weather shelter. It will keep you dry from the rain and also provide shade from the sun.

Tarps will not fit your tent floor as accurately as footprints unless you cut them to shape as well. Similar to footprints, tarps are also made of waterproof material. What makes tarps a better choice in our books is the fact that you can use them in a variety of ways. But, you should pick one that fits your comfort demands and other needs the best.

Frequently Asked Questions

Q. Should You Put A Tarp Under Your Tent?

It is important to place an intermediary layer of clothing to protect your tent floor from the earth’s roughness and moisture. Tarps can repel water and are thick enough to even out bumpy surfaces.

So, you should put a tarp under your tent for comfortable sleeping space and extend the lifetime of your tent floor.

Q. What Is The Ideal Tarp Size To Put Under My Tent?

You might think that the tarp size that has the same size as your tent floor would be the best. But, it would be even better if you choose a tarp that falls two to three inches shorter than your overall floor measurements. If the tarp completely stays inside the tent, there will be no chance of water pooling outside the tent.

Final Say

The best tarp for under tent can do more than providing safety for your tent floor. A tarp is a resourceful tool that any camper would find useful. We have analyzed the best tarps in the market and highlighted the ones we felt ticked all the right boxes. Hopefully, you will find the perfect tarp for you from the tarps we have reviewed above.
