Custom Size 11ft x 19ft Black Rectangle Sun Shade Sail - UPF50

Our review of the custom size 11' x 19' black rectangle sun shade sail finds it best for homeowners and light commercial spaces that need reliable sun protection without a permanent structure. The single biggest reason to buy is the material performance: the 200 GSM HDPE fabric blocks up to 95% of UV rays while remaining water and air permeable, so it cuts heat while avoiding the "sail" effect in wind. Installation is straightforward for anyone comfortable with basic measuring and hardware, and the product ships ready to be trimmed to precise D-ring-to-D-ring sizes.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric provides substantial sun protection, reducing UV exposure for families and guests.
• Temperature reduction: The shade surface can lower ambient temperatures by up to 15 degrees compared with unshaded spots, making patios and play areas more comfortable.
• Water and air permeable: The weave allows rain and breeze to pass through, reducing wind load and pooling compared with solid canopies.
• Customizable fit: Measured from D-ring to D-ring, the sail can be ordered to match irregular spaces and straight-edge options are available on request.
• Durable construction: Stainless steel D-rings, reinforced edges, and double-layer stitching increase longevity and resist fraying.
• 3-year assurance: A included three year assurance offers added confidence for long-term outdoor use.

Who It's For

This shade sail is aimed at homeowners, rental property managers, and light commercial operators who want a semi-permanent shade solution that is breathable and effective at blocking UV. It suits patios, play areas, poolside seating, car covers, and pergola tops where a tailored rectangle fit is needed.

People who need a rigid waterproof canopy, a fully enclosed gazebo, or a quickly removable umbrella should look elsewhere; the sail is breathable and meant to reduce heat rather than shed heavy, sustained downpours like a solid tarp would.

Pros & Cons

Pros

• High UV protection from the 200 GSM HDPE material that blocks up to 95% of rays.

• Durable hardware and reinforced stitching improve long-term performance in outdoor conditions.
• Custom sizing from D-ring to D-ring allows a tailored fit for awkward areas.

Frequently Asked Questions

Is this shade sail waterproof?
Answer. The fabric is water permeable to prevent pooling and reduce wind load, so it is not fully waterproof for heavy, sustained rain.

How should I measure for a custom sail?
Answer. Measure from D-ring to D-ring at the attachment points you will use and allow the recommended corner gaps; reach out to the seller for straight-edge customization if required.

What hardware is included?
Answer. The sail includes stainless steel D-rings and reinforced edges; mounting hardware kits are recommended and can be used to attach to trees, walls, poles, or roofs.
