Custom Size 19ft x 20ft Blue Rectangle Sun Shade Sail - UPF50

Our review finds the custom size 19' x 20' blue rectangle sun shade sail is a practical choice for homeowners and light-commercial spaces that need reliable sun protection. In this review the biggest reason to buy is the combination of heavy-duty 200 GSM HDPE fabric and reinforced construction that blocks up to 95% of UV, delivering noticeable cooling and long-term durability without looking obtrusive. It works well where a tailored fit matters and where a breathable, water- and air-permeable canopy is preferred over solid rigid shading.

Key Features

• 95% Sun Protection: The 200 GSM HDPE material blocks up to 95% of harmful UV rays for safer outdoor use.
• Temperature Reduction: Installed shading reduces ambient temperatures by up to 15 degrees compared to unshaded areas, making patios and play areas more comfortable.
• Customizable Fit: The sail is made to precise D-ring to D-ring measurements so it can be tailored to the mounting points for a neater, more effective installation.
• Heavy Duty Construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve longevity and resist fraying in regular use.
• Breathable & Water Permeable: The HDPE weave lets air and water pass through, reducing wind stress and preventing puddling on the canopy surface.
• 3-Year Assurance: A three-year assurance gives added confidence in material and workmanship for normal outdoor conditions.

Who It's For

This shade sail is ideal for homeowners, small business owners and property managers who need a tailored shading solution for patios, playgrounds, pool areas or outdoor dining spaces. It suits buyers who prefer a breathable, fabric canopy that reduces heat while remaining water and air permeable.

Those who need a rigid, fully waterproof roof or who require very frequent temporary relocation may want to consider alternate awning types; this product is best when installed semi-permanently with fixed anchor points and occasional seasonal removal.

Pros & Cons

Pros

• High UV blockage and material quality provide effective long-term sun protection.
• Custom sizing from D-ring to D-ring allows a tailored, neat installation for awkward spaces.
• Breathable design reduces wind loading and prevents water pooling compared with solid covers.
• Stainless steel D-rings and reinforced stitching contribute to a durable commercial standard build.

Cons

• The sail is water permeable, so it will not provide a fully waterproof canopy in heavy rain.
• Precise measurement and semi-permanent mounting hardware are required for best performance, which may be challenging for casual DIYers.

Our Verdict

The 19' x 20' custom rectangle shade sail is a strong value for anyone needing reliable UV protection, temperature reduction and a tailored fit for outdoor spaces. Its heavy-duty fabric, reinforced hardware and breathable design make it a sensible choice for semi-permanent installation where cooling and durability matter more than full waterproofing.
