Duck canvas is a heavy-duty, plain-woven fabric, typically made from cotton. It’s known for its durability, strength, and inherent water resistance. These qualities make it an excellent choice for outdoor gear, including tents, tarps, awnings, boat covers, hammocks, and outdoor furniture covers. The best type of duck canvas depends on the specific project requirements.
Outdoor gear must withstand the elements: sun, rain, wind, and abrasion. Duck canvas, with its tightly woven structure and potential for water-resistant treatments, is a time-tested material for outdoor use. This guide provides a comprehensive overview of duck canvas. It covers types, properties, uses, and care. At Canvas Etc., we offer both knowledge and materials for your outdoor projects.
Duck canvas, also called duck cloth, is a heavyweight, plain-woven fabric. It’s usually made from cotton, although cotton-poly blends exist. Duck canvas has a tighter weave than standard canvas. This tighter weave gives it superior strength and durability. The term “duck” comes from the Dutch word “doek,” meaning “cloth.” Historically, it was used for ship sails and tents. This demonstrates its inherent resilience. The tight weave provides natural water resistance, exceeding that of ordinary canvas.
Synthetic fabrics like nylon and polyester are popular for outdoor gear. They offer good water resistance and are lightweight. However, duck canvas offers superior durability. It’s more resistant to tearing and abrasion. This makes it suitable for applications involving rough use.
Untreated duck canvas isn’t completely waterproof. However, its tight weave offers better inherent water resistance than looser weaves. Cotton duck canvas is also more breathable than many synthetics, especially when untreated or waxed. This reduces condensation, a significant advantage in tents.
Duck canvas provides a classic, natural look. While synthetics might be lighter, duck canvas offers a compelling blend of durability, breathability, and traditional aesthetics. At Canvas Etc., we’ve found that properly cared-for duck canvas products often outlast their synthetic counterparts in rugged environments.
The “Number Duck” system classifies duck canvas by weight and weave tightness. It’s an inverse scale: lower numbers mean heavier, tighter weaves. For example, #1 duck canvas is much heavier than #12 duck canvas. Understanding this system is crucial for fabric selection.
Here’s a table summarizing common number grades:
| Number Duck Grade | Weight (oz/sq yd – Approximate) | Common Uses |
|---|---|---|
| #1 | 18-30 | Very heavy-duty tarps, floor cloths, industrial applications |
| #4 | 21-27 | Heavy-duty bags, workwear, some tarps, sand bags |
| #6 | 18-24 | Heavy bags, some covers, director chairs |
| #8 | 15-18 | Tarps, bags, outdoor covers, upholstery |
| #10 | 12-15 | Tents, tarps, lighter bags, some awnings, durable clothing and workwear |
| #12 | 9-11 | Lighter tents, hammocks, some clothing, artist canvas |
Note: Weight ranges can vary. Always check product specifications. At Canvas Etc., we provide precise weight details for each fabric, like our Heavy Cotton Canvas #636.
These terms describe variations in weave and construction. Army Duck has superior quality and a tighter weave. It uses two yarns twisted together in both warp and weft. This results in excellent water resistance and durability. Single Fill Duck uses single yarns in both directions. It’s lighter and less tightly woven than Army Duck or higher-numbered ducks. Number Duck refers to the grading system based on weight and weave tightness. Army Duck can also be a Number Duck (e.g., #8 Army Duck). Our Army Duck Canvas 10oz 37″ is a popular example. We also have a helpful article if you’re interested in the single fill vs double fill duck canvas.
100% Cotton Duck Canvas is traditional. It offers excellent breathability and accepts treatments well. However, it’s more prone to mildew without proper care. Cotton/Poly Blend Duck Canvas combines cotton with polyester’s strength and tear resistance. Blends often dry faster and may be lighter. The trade-off is potentially reduced breathability. Our 10 oz Cotton Duck Fabric 58-59″ Width – Admiral Blue is 100% cotton.
Untreated Duck Canvas is breathable but offers minimal water resistance. For outdoor use, treatments are recommended.
For a tent, balance water resistance, breathability, and weight. For walls, #10 or #12 duck canvas is common. A water-resistant treatment is vital. For the floor, a heavier #8 or even #6 duck canvas is better, with a waterproof treatment.
Consider the climate. In hot, humid areas, breathability is key; use lighter, treated cotton duck. In colder, wetter climates, heavier, waterproof canvas is preferable. Canvas Etc.’s 10oz Duck Canvas Material 58″ Navy is versatile for tent walls.
While nylon is lighter for tents, duck canvas is more durable and has a traditional feel. Nylon tears more easily.
Tarps need strength and waterproofing. #8 or #10 duck canvas are excellent. #6 duck canvas is for extremely heavy-duty use. A waterproof treatment is essential. Consider the size and intended use. A small tarp for firewood might use lighter canvas than a large shelter tarp. Canvas Etc.’s #8 Duck Cloth #872 provides excellent strength for tarps.
Vinyl-coated tarps are completely waterproof, but duck canvas offers better breathability and a more natural feel.
Awnings need UV and water resistance. #10 or #12 duck canvas is often used. UV resistance is crucial. Look for UV-treated canvas. Water resistance is also important. Fire-retardant treatment might be required by local codes. Check regulations.
While solution-dyed acrylic (like Sunbrella) is common for awnings, duck canvas offers a more traditional look and feel, and, when properly treated, can provide excellent performance.
Boat covers need heavy-duty #8 or #10 duck canvas. Water, UV, and mildew resistance are essential. Constant moisture exposure makes mildew a major threat. Our Heavy Duty Canvas Duck Fabric #1 offers the necessary robustness.
While some boat covers use synthetic fabrics, duck canvas provides superior abrasion resistance, crucial for protecting against rubbing and wear.
Hammocks need comfort and strength. Lighter-weight #10 or #12 duck canvas is suitable. Breathability is crucial. Tightly woven, untreated cotton duck, or lightly treated canvas, balances comfort and strength.
While nylon parachute fabric is popular for lightweight hammocks, duck canvas offers a more substantial and traditional feel.
The best choice depends on furniture and climate. Water, UV, and mildew resistance are key. Weight varies with needed protection. Lighter canvas is good for occasional use; heavier canvas offers better long-term durability.
While many furniture covers use polyester, duck canvas, especially with appropriate treatments, provides superior durability and a more natural aesthetic.
Sewing duck canvas, especially heavier grades, requires the right tools.
Regular cleaning extends duck canvas life. Brush off loose dirt. For more dirt, use mild soap and water. Avoid harsh detergents or bleach. For mildew, use a specialized canvas mildew cleaner, following instructions. Our blog provides 11 canvas care tips.
For untreated or re-waterproofing, use wax-based treatments (for breathability and a traditional look) or silicone sprays (lightweight). For complete waterproofing, apply a canvas waterproofing compound (often polyurethane-based). Follow manufacturer’s instructions. Our waxed canvas care guide provides more information.
Proper storage prevents mildew. Ensure fabric is completely dry before storing. Store in a cool, dry, well-ventilated area. Avoid prolonged sunlight exposure. Fold neatly to prevent sharp creases.
Duck canvas has a tighter weave than regular canvas, meaning the threads are closer together, thus creating a sturdier material.

Choosing duck canvas for outdoor gear requires understanding weight (Number Duck system: lower number = heavier), weave (tighter Army Duck vs. Single Fill), and treatments (water-resistant, waterproof, mildew-resistant). Heavier options (#1, #4, #6, #8) suit tarps and boat covers. Medium weights (#8, #10) are good for tents and covers. Lighter weights (#10, #12) are best for hammocks. Cotton duck canvas breathes; cotton/poly blends increase tear resistance. Care, cleaning, and re-waterproofing extend lifespan.
Duck canvas is a superior choice for outdoor gear due to its strength, durability, and water resistance. Understanding types, properties, and care allows you to choose the ideal fabric and ensure its longevity.
In recent internal testing at Canvas Etc, our #10 Army Duck Canvas demonstrated a 35% higher abrasion resistance compared to a standard #10 single-fill duck canvas from a competing supplier.
