Custom Size 12ft x 19ft x 22.5ft Right Triangle Sun Shade Sail

Our review of this custom right triangle shade sail finds it best suited to homeowners or small commercial spaces needing tailored shade and solid sun protection. The single biggest reason to buy is the combination of heavy-duty 200 GSM HDPE fabric with 95% UV blockage, which delivers noticeably cooler, protected outdoor areas while resisting fray and wind. Installation requires some planning for corner gaps and attachment points, but once in place the sail consistently reduces temperature and preserves color and function in direct sun.

Key Features

• 95% UV Blockage: The fabric blocks most harmful rays so shaded areas stay safer for people and furnishings.
• 200 GSM HDPE Construction: A thicker commercial-grade weave improves tear resistance and long-term durability in sun and wind.
• Temperature Reduction: The sail can lower ambient temperature by up to 15 degrees compared to unshaded areas for more comfortable outdoor use.
• Custom Fit: Measured D-ring to D-ring sizing and available straight-edge customization ensure a tailored canopy for irregular spaces.
• Reinforced Hardware: Stainless steel D-rings and double-layer stitching at the corners limit fraying and provide secure anchor points.
• Air and Water Permeable: The weave sheds some water and allows airflow, reducing sail flapping and wind load.

Who It's For

This shade sail is ideal for patio and garden owners who need a custom-sized solution, such as odd-shaped patios, poolside areas or cafe terraces that require a specific right triangle layout. It suits people who value a heavy-duty fabric with long-term color accuracy and simple, flexible mounting options to trees, posts or building corners.

Those who should look elsewhere include buyers wanting a fully waterproof canopy or a no-tools, pop-up product; this sail is water-permeable and requires proper attachment points and basic hardware. Also, extremely large commercial installations may prefer factory-designed tension systems rather than a customer-measured sail.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring for each side and allow the recommended corner gap of at least 0.5 ft, reducing up to 1 to 1.5 ft per side only if instructed.

Is the sail waterproof?
No, it is water and air permeable; it sheds some water but is not a fully waterproof canopy.

What maintenance keeps the sail lasting?
Clean dirt with a soft brush and mild soap, keep sharp objects away from edges, and re-tension or check D-rings seasonally to prevent undue wear.
