Custom Size 13ft x 20ft x 23.9ft Right Triangle Sun Shade Sail - UPF50

In this review of the custom size right triangle shade sail, the bottom line is simple: this is a practical, heavy-duty sun canopy for anyone who needs tailored UV protection over patios, play areas, or animal runs. The sail's strongest selling point is its combination of 95% sun blockage and sturdy construction, which together deliver noticeably cooler, safer shade. Installation requires planning and basic hardware, but when fitted from D-ring to D-ring to the specified dimensions it provides durable, effective coverage.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful sun rays so shaded areas are safer for people and pets.
• Temperature reduction: The sail can lower ambient temperature by as much as 15 degrees compared with unshaded spaces, improving comfort on hot days.
• Custom sizing: Measurements taken from D-ring to D-ring allow a tailored fit for odd corners or specific coverage requirements.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching reduce fraying and improve long-term performance.
• Breathable and water permeable: The woven HDPE fabric lets air and water pass through, reducing wind resistance and pooling during rain.
• Three year assurance: The product includes a three year assurance period for added confidence in commercial-standard materials and assembly.

Who It's For

This shade sail suits homeowners, small businesses and hobby farmers who need a custom-shaped canopy for patios, playgrounds, garden seating, or animal shelters and value strong UV protection and durability. It is particularly useful where fixed structures are impractical and where airflow and some water permeability are desired.

People who prefer a plug-and-play off-the-shelf size or who need a fully waterproof cover should look elsewhere; this sail is designed as a ventilated, sun-focused canopy and requires accurate D-ring to D-ring measurements and basic mounting preparation.

Pros & Cons

Pros

• High sun protection with 95% UV blockage for safer outdoor time.
• Good durability thanks to stainless steel D-rings, reinforced edges and double stitching.
• Custom sizing makes it adaptable to odd or asymmetrical spaces where standard sails fail.
• Breathable weave reduces heat buildup and performs well in wind compared with solid tarps.

Cons

• Requires careful measuring and planning; customers noted size can feel smaller than expected if measurements are off.
• Not fully waterproof, so it will not keep heavy rain off like a solid canopy.

Frequently Asked Questions

Is this sail waterproof?
The fabric is water permeable, so it sheds some water but is not a fully waterproof cover for heavy rain.

How should I measure for a custom fit?
Measure from D-ring to D-ring for each corner and allow the recommended gap from mounting posts; accurate measurement is essential for a proper fit.

How durable is the hardware?
The sail uses stainless steel D-rings and reinforced edges with double-layer stitching for improved durability and resistance to fraying.
