Custom Size 11ft x 21ft Brown Rectangle Sun Shade Sail - UPF50

Our review of the Custom Size 11' x 21' Brown Rectangle Sun Shade Sail finds it ideal for homeowners and small businesses who need strong, customizable sun protection without permanent construction. The single biggest reason to buy is the reliable 95% UV blockage from its 200 GSM HDPE fabric, which makes it useful for patios, playgrounds, and outdoor dining where shade and temperature control matter. Installation is flexible enough for DIYers who can measure D-ring to D-ring and adapt corners to trees, poles or walls.

Key Features

• 95% Sun Protection: The 200 GSM HDPE material blocks up to 95% of UV rays to reduce direct sun exposure for people and furnishings.
• Temperature Reduction: The canopy lowers ambient temperature by up to 15 degrees compared to unshaded areas, creating a noticeably cooler outdoor space.
• Durable Construction: Stainless steel D-rings, reinforced edges and double-layer stitching resist fraying and prolong service life under regular use.
• Custom Fit: Made to order by measuring from D-ring to D-ring so the sail matches the intended coverage area and mounting points.
• Permeable Design: The water and air permeable weave avoids ponding and reduces wind loading while still providing strong shade.
• 3-Year Assurance: Includes a three year assurance period that reflects the manufacturer confidence in material and workmanship.

Who It's For

The shade sail is best for homeowners, cafes, and property managers who need a tailored shade solution for patios, decks, playgrounds or garden seating areas and want a heavy-duty, commercial-standard fabric. It suits DIY installers who can take precise D-ring to D-ring measurements and attach the corners to trees, poles or structural anchors.

Those who should look elsewhere include buyers who need rigid, waterproof awnings or permanent structures; this product is water permeable by design and not a substitute for a solid roof. Also, customers wanting instant off-the-shelf sizes without custom measuring may prefer pre-cut sails from other lines.

Frequently Asked Questions

Is this shade sail waterproof?
The fabric is water and air permeable, so it will not be fully waterproof or prevent all rain from passing through.

How should I measure for a custom sail?
Measure from D-ring to D-ring for each side; allow at least 0.5 ft gap between D-rings and poles or adjust 1 to 1.5 ft per side as recommended for clearance.

Will it hold up in wind?
With proper installation and secure anchor points, the heavy-duty fabric and reinforced edges provide good wind resistance for typical outdoor conditions.
