Custom Size 17ft x 20ft Black Rectangle Sun Shade Sail - 95% UV

Our review of the custom size 17' x 20' black rectangle sun shade sail finds it best suited for homeowners and small commercial settings that need reliable sun protection without blocking airflow. The single biggest reason to buy is its combination of 95% UV protection and sturdy construction: made from 200 GSM HDPE with reinforced edges and stainless steel D-rings, this sail cuts sun exposure and lowers ambient temperature in shaded spots. Installation is flexible and the sail is designed to be customized to measured D-ring distances for a tailored fit.

Key Features

• 95% Sun Protection: Blocks up to 95% of harmful UV rays for safer outdoor time and reduced sunburn risk.
• Temperature Reduction: Lowers shaded area temperatures by as much as 15 degrees compared with direct sun, making patios and play areas more comfortable.
• Durable Material: Constructed from 200 GSM HDPE with double-layer stitching to resist fraying and prolong service life.
• Customizable Fit: Made to order using D-ring to D-ring measurements so the sail matches the exact shape and span required.
• Stainless Steel Hardware: Includes stainless steel D-rings and reinforced edges for reliable anchoring and long-term durability.
• Air and Water Permeable: Allows breezes through while shedding some rain, reducing wind load and flapping.

Who It's For

This shade sail is aimed at homeowners, rental property managers, and small business owners who want a tailored shading solution for patios, decks, playgrounds, or outdoor seating. People who value a cooler shaded area and high UV blockage will appreciate the 200 GSM HDPE construction and customizable sizing.

Those who need a rigid, fully waterproof canopy or who cannot access secure mounting points should look elsewhere; the sail is water permeable and needs proper anchor spacing and hardware to perform optimally. Also verify measurements carefully, since fit depends on D-ring to D-ring sizing.

Pros & Cons

Pros

• Excellent sun blockage and measurable temperature reduction under the sail.
• Solid build with stainless steel D-rings and reinforced, double-stitched edges for lasting use.
• Flexible installation options let you attach to trees, posts, walls, or roofs and adjust corner gaps for tension.
• Custom sizing ensures a neat fit for irregular or specific areas.

Cons

• Not fully waterproof; it is water and air permeable, so heavy rain may pass through or drip.
• One reported customer discrepancy on advertised dimensions suggests careful measurement and confirmation are needed before ordering.

Our Verdict

For anyone seeking a sturdy, customizable shade solution that blocks the majority of UV and meaningfully cools outdoor spaces, this 17' x 20' custom rectangle sail represents good value given its heavy-duty 200 GSM fabric and reinforced fittings. It is especially strong for patios, play areas, and outdoor seating where airflow and sun protection matter, but buyers should confirm exact measurements and understand it is not a fully waterproof canopy.
