Custom Size 9 ft x 15 ft x 17.5 ft Right Triangle Sun Shade Sail

Our review of this custom right triangle sun shade sail finds it best suited for homeowners and small commercial spaces that need a tailored, heavy-duty sun solution. The single biggest reason to buy is its combination of dense 200 GSM HDPE fabric and 95% UV blockage, which delivers reliable sun protection and a measurable temperature drop in shaded areas. Installation takes some planning but the reinforced edges and stainless steel D-Rings give confidence that the sail will hold up through wind and sun once mounted correctly.

Key Features

• 95% UV blockage: The fabric blocks most harmful UV rays so shaded areas are safer for extended outdoor use.
• 200 GSM HDPE construction: The heavier textile delivers improved durability and resistance to fraying compared with lighter sails.
• Temperature reduction: The sail can lower ambient temperatures by up to 15 degrees versus unshaded spots, making patios and play areas noticeably cooler.
• Custom measurements: The product is made to order from D-ring to D-ring so it can be tailored to fit specific layouts and mounting points.
• Stainless steel hardware: Reinforced edges and stainless D-Rings with double stitching improve longevity and hold under tension.

Who It's For

This shade sail is ideal for people who have a specific triangular area to shade and want a durable, tailored solution rather than a one-size item. It works well for patios, pergolas, playground corners, or small commercial seating areas where temperature reduction and high UV protection matter.

Those who should look elsewhere include buyers who need an off-the-shelf square or rectangular sail without customization, or anyone unwilling to plan mounting distances carefully, since correct D-ring to pole gaps and professional-grade fixings affect performance.

Pros & Cons

Pros

Our Verdict

This custom right triangle shade sail is a good value for anyone who needs robust UV protection and a tailored fit; the heavy 200 GSM fabric and reinforced hardware justify the effort of measuring and planning installation.

Frequently Asked Questions

How do I measure for a custom sail?
Measure from D-ring to D-ring along each side and provide those dimensions so the sail is made to fit the exact mounting points.

Will the sail block rain?
The fabric is water permeable so it provides shade while allowing some water and air to pass through, reducing pooling and wind stress.

What gap is recommended between D-Rings and poles?
For best performance allow at least 0.5 ft gap at each corner, or reduce by 1 to 1.5 ft per side if needed when anchoring to closer points.
