Selecting the right tarp thickness guide demands careful consideration. Material Strength, a critical factor, influences the tarp’s resilience. Grommet Spacing, a related element, affects its ability to be securely fastened. Industrial applications often necessitate heavier-duty tarps than residential uses. Evaluating environmental conditions is paramount; for instance, areas with intense UV radiation benefit from UV-resistant materials described in this tarp thickness guide.

Unveiling the Secrets of Tarp Thickness: Your Comprehensive Guide
This guide aims to demystify tarp thickness, providing you with the knowledge to choose the right tarp for any job, saving you money and frustration in the process. We’ll explore different thickness measurements, tarp materials, and their ideal applications.
Understanding Tarp Thickness Measurements
Knowing how tarp thickness is measured is crucial. There are two primary ways: mil and GSM.
Mil Explained
Mil is a unit of measurement equaling one-thousandth of an inch (0.001 inch). This measurement is often used to describe the thickness of plastic sheeting and tarps. A higher mil number indicates a thicker, more durable tarp.
- Advantages: Relatively easy to understand; provides a direct measurement of thickness.
- Disadvantages: Can be less precise than GSM, especially with thicker tarps.
GSM Explained
GSM stands for "Grams per Square Meter." It represents the weight of the tarp material per square meter. A higher GSM value signifies a heavier, denser, and generally more durable tarp.
- Advantages: Provides a more precise indication of material density.
- Disadvantages: Can be less intuitive than mil; doesn’t directly translate to thickness in inches.
Different Tarp Materials and Their Thickness Ranges
The material a tarp is made from greatly affects its overall durability and thickness requirements for a specific task. Common tarp materials include polyethylene (PE), canvas, and vinyl.
Polyethylene (PE) Tarps
PE tarps are widely used due to their affordability and versatility. Their thickness is typically measured in mil.
- Light-Duty PE Tarps (5-6 mil): Suitable for temporary covers, ground covers, and light-duty applications.
- Medium-Duty PE Tarps (8-12 mil): Offer increased durability for general-purpose use, such as covering equipment or firewood.
- Heavy-Duty PE Tarps (14-20 mil): Designed for demanding tasks, including construction, roofing, and long-term outdoor storage.
- Super Heavy-Duty PE Tarps (20+ mil): Provide maximum protection for extreme conditions and heavy-duty applications.
Canvas Tarps
Canvas tarps are known for their breathability and durability. Their thickness is often described by their weight in ounces per square yard.
- Advantages of Canvas: Breathable, water-resistant (when treated), and durable.
- Disadvantages of Canvas: Heavier than PE, can be more expensive, and susceptible to mildew if not properly cared for.
Vinyl Tarps
Vinyl tarps offer superior waterproof protection and resistance to abrasion. Their thickness is typically measured in mil or ounces per square yard.
- Advantages of Vinyl: Completely waterproof, resistant to abrasion and chemicals, and highly durable.
- Disadvantages of Vinyl: Can be heavier and more expensive than PE, less breathable.
Matching Tarp Thickness to Your Needs: Application-Specific Guidance
Choosing the correct tarp thickness depends entirely on the intended use. Here’s a breakdown of common applications and corresponding recommended thicknesses.
Construction Sites
- Debris Containment: Medium-duty PE tarps (8-12 mil).
- Equipment Covering: Heavy-duty PE tarps (14-20 mil) or vinyl tarps.
- Temporary Roofing: Super heavy-duty PE tarps (20+ mil) or reinforced vinyl tarps.
Camping and Outdoor Recreation
- Ground Cover: Light-duty PE tarps (5-6 mil).
- Tent Fly: Medium-duty PE tarps (8-12 mil) or canvas tarps.
- Emergency Shelter: Heavy-duty PE tarps (14-20 mil).
Agriculture and Gardening
- Mulch: Light-duty PE tarps (5-6 mil).
- Equipment Covering: Medium-duty PE tarps (8-12 mil).
- Hay Bale Protection: Heavy-duty PE tarps (14-20 mil) or canvas tarps.
Transportation and Storage
- Truck Bed Cover: Heavy-duty PE tarps (14-20 mil) or vinyl tarps.
- Boat Cover: Super heavy-duty PE tarps (20+ mil) or reinforced vinyl tarps.
- Firewood Covering: Medium-duty PE tarps (8-12 mil)
Tarp Thickness Comparison Table
| Application | Tarp Type | Thickness (Approximate) | Key Features |
|---|---|---|---|
| Ground Cover | PE | 5-6 mil | Lightweight, inexpensive |
| Equipment Cover | PE/Vinyl | 8-12 mil | Durable, general-purpose |
| Construction Debris | PE | 8-12 mil | Tear-resistant, weather-resistant |
| Hay Bale Protection | PE/Canvas | 14-20 mil | Heavy-duty, breathable (canvas), durable |
| Truck Bed Cover | PE/Vinyl | 14-20 mil | Waterproof, abrasion-resistant |
| Roofing/Boat Cover | PE/Vinyl | 20+ mil | Ultra-durable, maximum protection |
Tarp Thickness Guide: FAQs
Choosing the right tarp thickness can seem confusing. Here are some frequently asked questions to help you make the best choice and save money.
What do "mil" and "GSM" mean when describing tarp thickness?
"Mil" is a unit of measurement equal to one-thousandth of an inch, used to describe the thickness of plastic tarps. "GSM" stands for grams per square meter and measures the density of the tarp material. Higher mil and GSM numbers generally indicate a thicker, more durable tarp.
What’s the best tarp thickness for outdoor furniture covers?
For general outdoor furniture protection, a medium-duty tarp around 5-6 mil is usually sufficient. These offer a good balance of durability and affordability. Check our tarp thickness guide for specific recommendations based on your climate.
Can I use a thinner tarp if I’m on a tight budget?
Yes, but understand that thinner, less expensive tarps are more prone to tearing and won’t last as long. Consider whether the short-term savings are worth the potential for replacement costs and damage from exposure. The tarp thickness guide highlights budget options with their trade-offs.
How does UV resistance relate to tarp thickness?
While UV resistance is often added as a coating, thicker tarps inherently offer more UV protection because the material itself provides a barrier. Look for tarps specifically labeled as UV resistant, regardless of thickness, especially for prolonged outdoor use. Our tarp thickness guide lists UV-resistant options at various mil levels.
So, hopefully, this has helped you navigate the world of tarp thickness guide options! Choosing the right tarp can save you a lot of headaches (and money!), so get out there and find the perfect fit for your needs.
