Common Types of Tarps
Tarps are manufactured from several different materials, each designed for specific applications and environments.
Poly Tarps
Polyethylene tarps are the most widely used type of tarp due to their affordability, waterproof protection, and lightweight design. Poly tarps are commonly used for construction projects, equipment covers, and temporary weather protection.
Vinyl Tarps
Vinyl tarps are extremely durable and designed for heavy-duty applications where long-term outdoor exposure is expected. These tarps are often used for trucking, industrial protection, and large equipment covers.
Canvas Tarps
Canvas tarps are breathable and well suited for covering materials that require airflow, such as wood, machinery, and agricultural supplies.
Understanding Tarp Thickness (Mil Ratings)
Tarp thickness is typically measured in mils, which represents one thousandth of an inch. Thicker tarps generally offer greater durability and tear resistance.
- 5–6 Mil: Light-duty tarps for temporary use
- 10–12 Mil: Medium-duty tarps for general outdoor protection
- 16–20 Mil: Heavy-duty tarps designed for construction and long-term outdoor exposure
Tarp Thickness Chart
Tarp thickness is one of the most important factors when choosing a tarp for your project. Thickness is measured in mils (one thousandth of an inch) and generally indicates the strength and durability of the tarp material. The chart below provides a simple comparison of common tarp thickness levels and their typical uses.
| Tarp Thickness | Duty Level | Typical Uses |
|---|---|---|
| 5–7 Mil | Light Duty | Temporary cover, camping, short-term protection |
| 8–10 Mil | Medium Duty | Home improvement, yard work, seasonal coverage |
| 11–12 Mil | Heavy Duty | Equipment protection, roofing projects, construction sites |
| 13–20 Mil | Extreme Duty | Industrial use, long-term outdoor protection, heavy equipment coverage |
Understanding tarp thickness can help you choose a tarp that will last longer and perform better in demanding conditions. For projects requiring maximum durability, contractors often choose heavy-duty tarps with reinforced mesh counts and thicker coatings.
Choosing the right thickness depends on how long the tarp will be used and the type of environment it will be exposed to.
What is Tarp Mesh Count?
Mesh count refers to the number of polyethylene threads per square inch used to reinforce a tarp. Higher mesh counts typically indicate stronger and more durable tarps.
For example, a 14x14 mesh tarp contains 14 threads per inch in both directions, providing increased tear resistance and strength.
How to Choose the Right Tarp Size
Tarps are usually listed by their cut size before hems and grommets are installed. After finishing, the final tarp size is typically 4–6 inches smaller in each direction.
When selecting a tarp, measure the area you want to cover and allow extra material for securing the tarp with ropes, bungee cords, or tie-downs.
Best Tarps for Common Applications
Construction Sites
Heavy-duty poly or vinyl tarps provide excellent durability for covering building materials, tools, and work areas.
Roof Protection
Waterproof heavy-duty tarps are commonly used for emergency roof protection after storms or damage.
Camping and Outdoor Use
Lightweight waterproof tarps work well for camping shelters, ground covers, and rain protection.
Equipment Protection
Industrial-grade tarps provide long-term protection for machinery, vehicles, and agricultural equipment.
How to Secure a Tarp Properly
Proper installation ensures your tarp remains secure during wind, rain, and other weather conditions.
- Use bungee cords or rope through reinforced grommets
- Anchor the tarp tightly to prevent wind lift
- Avoid excessive tension that can tear grommets
- Use additional tie-down points for large tarps

Frequently Asked Questions About Buying Tarps
What tarp thickness should I choose?
Tarp thickness is measured in mils and generally determines durability. Light-duty tarps are typically 5–8 mil thick and are best for temporary coverage or short-term use. Heavy-duty tarps are often 12 mil or thicker and are designed for demanding environments such as construction sites, equipment protection, and long-term outdoor exposure.
Are poly tarps waterproof?
Yes, most polyethylene (poly) tarps are fully waterproof and designed to repel rain and moisture. Poly tarps are one of the most common tarp materials because they provide strong weather resistance while remaining lightweight and affordable.
Why are tarps smaller than the listed size?
Tarps are typically listed by their cut size before hems and grommets are installed. After finishing, the final tarp size is usually about 4–6 inches smaller in each direction. This difference is considered standard across the tarp industry.
What is mesh count in tarps?
Mesh count refers to the number of polyethylene strands woven per square inch of fabric. A higher mesh count generally means a stronger and more durable tarp. For example, a 14x14 mesh tarp contains 14 fibers in each direction per inch, providing greater tear resistance than lower mesh counts.
How do I secure a tarp properly?
Tarps should be secured using the reinforced grommets along the edges with rope, bungee cords, or ball ties. To prevent tearing, avoid pulling the tarp too tightly and allow some flexibility for wind movement. For step-by-step instructions, see our complete guide on how to secure a tarp.
Choosing the Right Tarp for Your Needs
Selecting the right tarp depends on the environment, durability requirements, and length of use. Contractors often choose heavy-duty poly or vinyl tarps for jobsite protection, while homeowners may prefer lighter-duty tarps for seasonal projects or outdoor storage. Understanding tarp thickness, mesh count, and materials can help ensure you choose a tarp that will perform reliably for your application.
