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

In this review of the custom size right triangle sun shade sail, the bottom line is simple: this is for homeowners or businesses who need a tailored, heavy-duty shade solution and want serious UV protection without a solid canopy. The sail's single biggest reason to buy is its combination of a dense 200 GSM HDPE fabric and reinforced hardware that together deliver up to 95% sun protection and notable temperature reduction. Installation takes some planning, but the customized D-ring-to-D-ring sizing and commercial-grade construction make it a durable, long-term option for patios, play areas, and outdoor seating.

Key Features

• 95% UV blockage: The fabric blocks up to 95% of harmful UV rays to protect skin and furnishings beneath the sail.
• 200 GSM commercial fabric: The heavy-duty HDPE weave offers a rugged, tear-resistant surface suited to frequent outdoor use.
• Temperature reduction: The sail can lower temperatures by up to 15 degrees in shaded areas, creating a noticeably cooler zone on hot days.
• Custom fit: The sail is made to order from D-ring to D-ring so customers can get a precise triangular fit for an irregular space.
• Reinforced hardware: Stainless steel D-rings, reinforced edges, and double-layer stitching improve durability and help the sail resist fraying.
• Water and air permeable: The breathable fabric sheds some water while allowing airflow, reducing wind lift and pooling.

Who It's For

The sail is best for homeowners, cafes, daycare centers, or anyone with a bespoke outdoor area who needs a sturdy, high-coverage shade solution that is sized to fit unusual layouts. It fits locations where permanent structures aren't desired and where breathability and UV protection matter more than full waterproofing.

Customers who want an off-the-shelf, instant pop-up canopy or a fully waterproof awning should look elsewhere; this product is designed as a tailored sun shade with some water permeability and requires measured installation and attachment points with gaps as recommended for best performance.

Pros & Cons

Cons

• Some buyers report the measured size can feel smaller than expected, so careful measurement is essential.

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring on the attachment points, allow at least 0.5 ft gap at each corner from poles or fixed mounts, and reduce side lengths by 1 to 1.5 ft if needed for tensioning.

Is this sail fully waterproof?
No, the fabric is water and air permeable; it sheds some water but is designed primarily for sun protection and airflow rather than complete waterproof coverage.

How durable is the hardware?
The sail uses stainless steel D-rings and reinforced edges with double-layer stitching, which customers report hold up well under sun and wind with proper installation.
