Custom Size 13ft x 16ft x 20.6ft Blue Right Triangle Sun Shade Sail

In this review of the custom size right triangle sun shade sail, the bottom line is simple: it is for anyone who needs a tough, tailored sun cover that blocks most UV while still allowing air and water to pass. The reviewer found the shade sail useful for patios, chicken runs, and small commercial canopies because of its 95% UV blockage and heavy 200 GSM HDPE construction. Installation is straightforward for a homeowner comfortable with simple rigging, and the option to order a made-to-measure D-ring-to-D-ring size is the single biggest reason to choose this product.

Key Features

• 95% Sun Protection: The 200 GSM HDPE material blocks up to 95% of harmful UV rays, improving safety in exposed outdoor areas.
• Temperature Reduction: The fabric reduces temperatures by up to 15 degrees beneath the sail, creating noticeably cooler shaded zones.
• Custom Fit: Customers supply D-ring-to-D-ring measurements so the sail fits tight to the intended footprint and avoids excess sagging.
• Durable Construction: Stainless steel D-rings, reinforced edges and double-layer stitching resist fraying and deliver commercial standard durability.
• Air and Water Permeable: The weave lets air and some water through, reducing wind lift and pooling while still providing shade.
• Installation Flexibility: Can be anchored to trees, roofs, walls or poles using common mounting hardware, and corner gaps can be adjusted for best tension.

Who It's For

This shade sail is best for homeowners, small business owners and hobby farmers who need a tailored cover for patios, seating areas, play spaces or animal enclosures and who value strong UV protection and commercial-grade materials. The custom sizing option makes it a good choice when standard sails are too small or oddly proportioned for an intended spot.

Those who should look elsewhere include buyers who want a fully waterproof canopy or expect a preassembled rigid frame; this sail is water and air permeable by design and requires anchoring hardware and some basic rigging to tension correctly. Also, shoppers seeking large off-the-shelf sizes without custom measurement may prefer standard fixed-size sails.

Pros & Cons

Pros

• High UV blockage and cooler shade thanks to the 95% blocking HDPE fabric.
• Sturdy components with stainless steel D-rings and reinforced double-stitched edges for durability.
• Custom sizing ensures a better fit for irregular or specific spaces.
• Permeable fabric reduces wind lift and pooling, increasing real-world usefulness.

Cons

• Size must be measured D-ring to D-ring and some customers report the finished sail can feel smaller than expected if measurements are off.
• Not fully waterproof, so it will not keep heavy rain from reaching the area beneath.
