Custom Size 19ft x 20ft Black Rectangle Sun Shade Sail - Tight Fit

Our review of the Custom Size 19' x 20' Black Rectangle Sun Shade Sail finds it best for homeowners and small businesses wanting a large, tailored shade solution with reliable UV protection. Measured corner to corner and built with curved edges to prevent sagging, this shade delivers a clean, tight appearance that stands out from off-the-shelf sails. The single biggest reason to buy is the combination of a custom fit and heavy UV-blocking fabric that reduces heat and preserves privacy across patios, pools, and carports.

Key Features

• Made for a Perfect Fit: Corner-to-corner measurements and curved edges mean the sail fits tightly without excess sag, giving a neat, professional look.
• Durable Material: Constructed from virgin polyethylene, the fabric stays lightweight yet strong for reliable long-term outdoor use.
• UV Blocking: Blocks up to 95% of UV rays and about 90% of visibility, providing significant cooling and added privacy for outdoor living areas.
• All-Season Use: Useful in summer for sun protection, at night to reduce frost, and during light rain to protect furniture and pathways.
• Custom Sizes Locally Made: Each sail is custom-made to fit your exact space and produced locally to keep lead times predictable.
• 3-Year Limited Warranty: Backed by a warranty that offers extra peace of mind against early failure or defects.

Who It's For

This shade sail is ideal for homeowners with patios, pools, balconies, carports, or driveways who need a large, tailored canopy that blends privacy with cooling performance. Installers and DIYers who can take accurate corner-to-corner measurements will appreciate the way curved edges reduce fabric sag and produce a tidy finished look.

It may be less suitable for buyers seeking full waterproof coverage in heavy storms or those wanting a rigid structure; this product is designed for sun and light weather protection rather than as a full awning replacement.
