Tarp prices range from about $5 for a small, lightweight cover to more than $500 for a large, heavy-duty custom tarp. Size, material, thickness, reinforcement, and whether the tarp is a standard or custom dimension have the biggest effect on the total.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small poly tarp, 6 × 8 ft | $5 | $9 | $18 | Light-duty cover |
| Medium poly tarp, 10 × 12 ft | $12 | $25 | $55 | Common household size |
| Large poly tarp, 20 × 30 ft | $55 | $110 | $220 | Thickness and grade matter |
| Heavy-duty vinyl tarp, 20 × 30 ft | $250 | $400 | $700 | Reinforced, longer-lasting option |
What common tarp sizes cost at retail
For standard polyethylene tarps, a 5 × 7-foot cover typically costs $4-$12, a 10 × 12-foot tarp $12-$55, and a 20 × 30-foot tarp $55-$220. These ranges reflect differences in thickness, weave, coatings, and retailer. A basic blue tarp is usually at the low end; UV-resistant or reinforced versions cost more.
Canvas usually costs more than basic poly, while vinyl is often the priciest material for comparable coverage. A 10 × 12-foot canvas tarp commonly runs $35-$100; a comparable vinyl tarp may cost $60-$160. Assumptions: U.S. retail pricing for standard finished tarps, before shipping and sales tax. For a typical household cover, budgeting $15-$60 for a medium poly tarp is a practical starting point.
How material, grommets, and reinforcement shape the quote
For a ready-made tarp, the material accounts for most of the price. Retail listings often identify poly weight in ounces per square yard or by a grade such as light, medium, or heavy duty. Stronger fabric, waterproof coatings, UV protection, and reinforced edges raise the price. Custom fabrication may add cutting, hemming, and hardware charges.
| Cost component | Low | Average | High | What changes the charge |
|---|---|---|---|---|
| Poly fabric, per sq ft | $0.05 | $0.12 | $0.30 | Thickness and UV treatment |
| Canvas fabric, per sq ft | $0.25 | $0.55 | $1.10 | Weight and water resistance |
| Vinyl fabric, per sq ft | $0.40 | $0.85 | $1.60 | Coating, weight, and strength |
| Custom hemming and grommets | $15 | $50 | $150 | Perimeter, spacing, and order size |
| Shipping for oversized orders | $10 | $35 | $100 | Package size and delivery distance |
Custom dimensions and edge finishing can cost as much as the fabric on small orders. Grommets are often included on retail tarps, but custom work may charge per grommet or by the finished edge.
Which tarp specifications change the price most?
Area is the clearest cost driver: doubling the tarp’s square footage usually raises material cost substantially, although larger standard sizes may offer a lower price per square foot. Compare the finished dimensions rather than assuming the listed size equals the usable covered area; hems and construction can affect measurements.
Thickness and intended service matter too. A lightweight tarp around 5-6 mil is suited to short-term, light-duty coverage; a 10-12 mil product generally costs more but handles more repeated use. For truck, equipment, or frequent outdoor use, reinforced corners, closely spaced grommets, and UV resistance may justify a higher grade. On a 20 × 30-foot tarp, upgrading from basic poly to heavy-duty poly can add roughly $50-$150.
When does a custom tarp cost more than a standard size?
Custom tarps are useful when a standard rectangle will not fit, but fabrication, finishing, and minimum order charges can push the bill above retail pricing. A simple custom poly tarp measuring about 12 × 18 feet may cost $100-$250 finished; heavy vinyl at the same size can reach $250-$500. Shape, cutouts, reinforced hems, and attachment points increase the estimate.
Ask whether the quote includes grommets, hems, taxes, and shipping, and confirm the finished dimensions in writing. For a single tarp, compare the custom quote with the next-largest standard size before ordering. Custom sizing is most economical when a close standard size would leave significant uncovered area or excess material.
Three tarp size examples for different coverage jobs
A 6 × 8-foot light-duty poly tarp covers 48 square feet and commonly costs $5-$18. It can cover a small stack of outdoor items, but offers limited overhang for tying down. A 10 × 12-foot medium-duty tarp covers 120 square feet and typically costs $18-$55, suitable for a patio set or modest load.
A 20 × 30-foot heavy-duty poly tarp covers 600 square feet and usually costs $100-$220; a comparable reinforced vinyl tarp may be $300-$700. These estimates are material-only retail prices, not installed costs. Measure the object and allow extra fabric on every side for draping and securement.
Why tarp prices differ between online and local stores
Basic poly tarps are commonly available at home-improvement stores, hardware retailers, and online, while specialty canvas and industrial vinyl may require a supplier or fabricator. Local stock can cost more than an online listing but avoids shipping fees and makes size verification easier. Oversized packages may carry delivery charges that erase an apparent online discount.
Prices also vary by region and season. In areas with frequent storms or high construction demand, popular heavy-duty sizes can cost about 5%-15% more or sell out during peak periods. Online bulk pricing may reduce the per-tarp rate by 10%-25% when buying several identical units. Compare the delivered total, not just the listed price.
How to reduce tarp spending without losing useful coverage
Start with measurements and choose the smallest size that still provides enough overlap and tie-down room. Buying much larger than necessary wastes material and can make the cover harder to secure in wind. For temporary use, a basic poly tarp may be sufficient; for repeated exposure, compare the replacement cost of thin poly with a more durable canvas or vinyl option.
Standard sizes usually cost less than custom cuts, and a multipack can lower the unit price for several small covers. Check the mil rating, actual dimensions, grommet spacing, and return policy before comparing similar-looking products. Avoid paying extra for UV protection or reinforced edges when the tarp will be used briefly indoors or in sheltered storage.
How long-lasting materials compare on replacement cost
Thin poly tarps are inexpensive but can wear, tear, or become brittle after prolonged sun and wind exposure. Medium- and heavy-duty poly cost more upfront and may be a better value for repeated seasonal use. Canvas can be repairable and breathable, but its water resistance depends on treatment and upkeep. Vinyl is often selected for demanding outdoor or commercial use because of its toughness, though its initial price is higher.
There is no dependable lifespan that applies to every tarp: exposure, tension, storage, and handling all matter. A tarp stretched tightly over a sharp edge may fail sooner regardless of material. Store a clean, dry tarp loosely folded and protect it from abrasion. For recurring use, compare the price per season rather than choosing solely by the lowest checkout price.
