Custom Size 5 ft x 7 ft x 8.6 ft Blue Right Triangle Sun Shade Sail

Our review of this custom size right triangle sun shade sail finds it best suited for homeowners or small businesses needing a tailored, durable cover for patios, play areas or animal enclosures. The biggest reason to buy is straightforward: it blocks up to 95% of UV while cutting ambient temperature by up to 15 degrees, so it delivers meaningful sun protection and cooler shade in a compact, customizable package. Assembly is simple for anyone comfortable with basic mounting points, and the material and reinforced stitching feel built to last.

Key Features

• 95% UV protection: Made from 200 GSM HDPE fabric that reliably blocks the majority of harmful sun rays for safer outdoor use.
• Temperature reduction: The shade sail can lower air temperature beneath it by up to about 15 degrees compared with unshaded areas, improving comfort on hot days.
• Custom fit: Measured D-ring to D-ring, the sail is made to order so it fits specific spaces and can be requested with straight edges if preferred.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching reduce fraying and support longer service life under sun and wind.
• Easy installation: Can be mounted to trees, roofs, walls or poles using common hardware kits and simple spacing guidance for secure attachment.
• Water and air permeable: The HDPE weave allows airflow and some water passage, reducing wind load and preventing pooling in light rain.

Who It's For

The shade sail is ideal for people who need a specific triangular coverage and want a product that is customizable to their measured space, such as small patios, outdoor chicken runs, pergolas or commercial seating areas where a tailored fit matters. It appeals to buyers who value a balance of sun protection and airflow rather than a fully waterproof canopy.

Those who need very large, fully waterproof canopies or fixed-frame umbrellas might look elsewhere, and shoppers expecting oversized dimensions beyond the ordered size should note customers occasionally report the sail feels smaller than anticipated, so double-check D-ring to D-ring measurements before ordering.

Pros & Cons

Pros

• High sun protection from 200 GSM HDPE fabric blocks up to 95% of UV for safer shade.
• Reduces temperature beneath the sail, making outdoor spaces noticeably cooler.
• Robust hardware and reinforced edges add durability and resistance to fraying.
• Made-to-measure option ensures a tailored fit for irregular spaces.

Cons

• Not fully waterproof since the material is water and air permeable, so it will not keep heavy rain fully out.
• Some customers found ordered size felt smaller than expected, so careful measuring is essential.

Frequently Asked Questions

Is this sail fully waterproof?
The fabric is water and air permeable, so it sheds light rain but is not designed to be fully waterproof in heavy downpours.

How should I measure for a custom fit?
Measure from D-ring to D-ring along the edges you intend to use and provide those exact dimensions when ordering for the best fit.

What hardware is required to install it?
Standard mounting hardware kits, poles, trees or wall anchors can be used; keep at least a 0.5 ft gap from D-rings to poles or reduce spacing as recommended for tension.
