Finding the right tarp for your needs requires understanding the trade-off between thickness and durability. A good tarp can provide protective equipment from the elements, keep supplies secure during transport, or even be used as a temporary shelter. Not all tarps are created equal: some materials, features, and thicknesses work better for specific needs than others. This guide will walk you through the essential factors you need to pay attention to when selecting a tarp while offering tips for making the right choice. After reading this article, you will know exactly what to consider to get a tarp that will stand the test of time and supply strength for your project.
What is Tarp Thickness and Why Does it Matter?
Tarp thickness is a measurement of a tarp’s material thickness and is usually expressed in mils (1 mil equals a thousandth of an inch). As a rule of thumb, thicker tarps are stronger and more durable than thinner ones. Thicker tarps are best suited for heavy-duty applications like protecting equipment or extreme weather, and can be relied on to last longer. For temporary uses of coverage or lightweight needs, thinner tarps do the job. No matter what type of project, every task requires the right tarp thickness; in this case, heavy-duty tasks require thicker tarps.
Understanding Mil Thickness in Tarps
Mil thickness is an accepted form of measuring one thousandth of an inch (0.001 inches). It shows how thick something is and is often used when referring to the thickness of tarps, higher mil value means thicker material which is more durable. Using mil thickness can make your selection of tarps easier depending on what you specifically need them for.
Lightweight tarps (5 to 8 mils thick) are usually used for temporary cover in situations such as firewood, small furniture covers, and surface drying during light rain. Medium-duty tarps (between 9 and 12 mils) are more durable and suitable for other tasks like camping, mid-weight equipment disguise, or boat covering.
From 13 mils to 20 mils, these are durable and used for high-performance tasks such as construction projects, industrial settings, and other projects that require the tarp to endure many harsh weather conditions.
To help you visualize:
- The thickness of a six-mil tarp is the same as a standard household trash bag.
- A 12 mil tarp is roughly equivalent to a painter’s drop cloth.
- A 20 mil tarp, which is 20 mil thinner than a credit card, is thick and robust.
For heavy-duty applications, reinforced tarps with a thickness exceeding 20 mils are available. These often have additional coatings for prolonged outdoor use, such as UV resistance or waterproofing.
In addition to tarp type, consider the material (canvas, vinyl, or polyethylene), application, and environmental conditions to achieve the desired durability.

The Importance of Choosing the Right Size and Thickness for Your Application
Finding a tarp’s appropriate size and thickness is critical in ensuring that it performs as expected. Each size, shape, and form has its purpose, and failure to follow the specifications can result in underperformance or, even worse, damage.
Tarp Size Considerations
Selecting a tarp’s size is directly proportional to the area one needs to cover and the protection level. An example would be the 20x20ft tarp, which is used in camping or for general construction. A 50×100-foot tarp is best suited for large-scale industrial or agricultural undertakings. It is recorded by the industry that tarps are best oversized by 2-3 feet in all dimensions to enhance secure fastening and improved coverage. As a rule of thumb, any tarp with reinforced edges and grommets will perform better in stability and durability.
Tarp Thickness Applications
Tarp thickness determines its strength and durability for its different uses. Here’s how industry recommendations align with tarp thickness:
- 5-8 Mil Tarps: These are best in performance furniture coverings, firewood or even lightweight temporary shelters. Their price is appealing, but they have little to no longevity in extreme conditions.
- 10-15 Mil Tarps: Mid-range tarps are durable enough to protect against tearing and offer a good price. They are best suited for vehicle coverage or roof patching.
- 20+ Mil Tarps: These are typically used in more demanding settings, such as construction and heavy equipment storage. Research shows that, when properly secured, these thicker tarps can withstand wind speeds of 70 mph.
- 30+ Mil Tarps: These are used for specialized tasks such as industrial storage or pond liners. Research indicates that tarps over 30 mils can extend service life by 30% under the same conditions as thinner options.
Other Important Information Also Worth Noting
- Weather Resistance: Many tarp materials are treated for UV resistance. Higher thickness options retain their protective qualities longer when exposed to sunlight.
- Waterproofing: Around 15-20 mils, tarps are especially preferred for water damage prevention in regions prone to storms. A study notes that over 75% of tarp losses during storms are caused by using too small or too thick tarps.
- Reuse and Longevity: Though thicker tarps may cost more initially, their greater potential for reuse provides better long-term value.
Conclusion:
Evaluating your surroundings alongside your project’s needs helps you select the best tarp. Remember to consider not just the dimensions and weight but also the material and extra treatments, such as UV shielding or flame resistance.
