Custom Size 13ft x 16ft x 20.6ft Right Triangle Shade Sail - Cooler

Our review of this custom-size right triangle shade sail finds it best suited for homeowners and small businesses who need a tailored sun cover with serious UV protection. The single biggest reason to buy is its combination of heavy-duty 200 GSM HDPE fabric and 95% UV blockage, which delivers noticeably cooler, protected outdoor space. Installation requires planning and precise D-ring-to-D-ring measurements, but once mounted the sail is stable, looks clean, and cuts temperatures by a visible margin in direct sun.

Key Features

• 95% Sun Protection: The fabric blocks up to 95% of UV rays so shaded areas stay safer for people and furniture.
• 200 GSM HDPE Construction: The heavier material provides commercial-grade durability and resists fraying under prolonged sun exposure.
• Temperature Reduction: The sail can lower temperatures in the covered area by up to 15 degrees compared with unshaded spots.
• Custom Fit: Measured from D-ring to D-ring, the sail is made to order so it fits irregular spaces better than off-the-shelf options.
• Reinforced Hardware: Stainless steel D-rings and double-layer stitching add strength at anchor points for longer service life.
• Breathable and Water Permeable: The weave lets air and water pass to avoid pooling and improve wind performance compared with solid canopies.

Who It's For

This shade sail is ideal for homeowners, patio installers, and small venues that need a right triangle canopy sized for a specific area and want reliable sun protection without a permanent structure. It fits spaces where trees, walls, or poles can serve as secure anchor points and where a professional-looking custom fit matters.

Those who should look elsewhere include buyers seeking a quick, pre-sized pop-up shade or anyone unwilling to take careful measurements; the made-to-order approach means some planning and correct D-ring spacing is required for best performance.

Pros & Cons

Frequently Asked Questions

How should I measure for a custom sail?
Measure from D-ring to D-ring when the sail will be tensioned and leave at least 0.5 ft gap at corners or subtract 1 to 1.5 ft per side as recommended for proper tension.

Will the sail hold up in wind and rain?
The 200 GSM HDPE fabric is breathable and water permeable which helps with wind performance; reinforced edges and stainless steel D-rings improve durability under severe sun and wind conditions.

Can I get straight edges instead of the standard finish?
Yes, customization for straight edges is available by contacting the maker to request that option during order to make.
