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

Our review of this custom size right-triangle shade sail finds it best for homeowners and small commercial spaces that need tailored sun protection with proven durability. The single biggest reason to buy is its combination of heavy-duty 200 GSM HDPE fabric and built-in stainless steel D-rings, which deliver reliable 95% UV blockage and a commercial-standard construction that stands up to sun and wind. Installation is straightforward for anyone comfortable with basic mounting hardware and measuring from D-ring to D-ring for a custom fit.

Key Features

• 95% UV Blockage: The fabric blocks up to 95% of harmful rays, giving real sun protection for patios, play areas, and outdoor seating.
• 200 GSM HDPE Material: A commercial-grade weave that balances strength and breathability so the sail resists tearing while remaining water and air permeable.
• Temperature Reduction: The shade can lower ambient temperatures by up to 15 degrees versus unshaded areas, improving comfort on hot days.
• Reinforced Construction: Stainless steel D-rings and double-layer stitching on the edges reduce fraying and extend service life under regular outdoor use.
• Custom Size Option: Measured D-ring to D-ring sizing allows a tailored fit for nonstandard spaces and the option to request straight edges if preferred.
• Flexible Mounting: Can be attached to trees, roofs, walls, or poles using standard mounting kits, with specific corner gap guidance for best performance.

Who It's For

This shade sail suits homeowners, backyard entertainers, and small businesses that need a large, durable triangular canopy with a custom fit. It is especially useful for patios, play areas, and outdoor dining spots where strong UV protection and lowered temperatures matter.

Those who want a simple, off-the-shelf size without measuring or who require a fully waterproof canopy should look elsewhere, since this product is engineered to be water and air permeable rather than fully rainproof. Buyers should also be prepared to measure accurately from D-ring to D-ring and follow installation clearance recommendations.

Frequently Asked Questions

Will this sail block most of the sun?
The fabric blocks up to 95% of UV rays and is rated UPF50+, so it provides significant sun protection for shaded areas.

Is it waterproof?
No, the material is water and air permeable by design; it reduces sun and heat but is not intended as a fully waterproof cover.

How should I measure for a custom fit?
Measure from D-ring to D-ring for each side and allow at least 0.5 ft gap for mounting; the manufacturer suggests reducing that gap by 1 to 1.5 ft per side if needed for specific installations.
