Custom Sun Shade Sail - Triangle

Description

Not every space you want to shade is a neat rectangle. A corner of the deck. The gap between the house wall and two posts. That triangle of patio the afternoon sun cooks while everything else stays comfortable. A triangle sun shade sail is made for exactly those spots — it needs only three anchor points, so it fits geometry a four-corner sail simply can't.

It's also the shape people reach for when they want the look. Overlap two or three triangles at different heights and you get that layered, sail-over-sail effect that turns plain shade into something architectural. Each one is cut to your exact three side lengths, so a custom triangle shade sail fits precisely between your chosen points instead of leaving one corner drooping.

The fabric is solution-dyed Sunbrella — dense, cool shade that breathes, sheds light rain, and holds its color through hard sun. As a patio shade sail triangle, it's equal parts function and finish.

How to Measure Your Triangle Shade Sail

A triangle is defined by its three sides — measure each one between the anchor points:

Step 1 - Side A–B
Measure the distance between your first and second anchor points.

Step 2 - Side B–C
Measure between the second and third anchor points.

Step 3 - Side C–A
Measure between the third and first anchor points. Send all three lengths (each up to 30 feet) and we cut the sail to sit taut between them. Mount to your own hardware, ideally with the three anchors at staggered heights so water sheds off.

Why Choose Our Triangle Sun Shade Sail?

Fits three-point and corner spaces
Only three anchors needed, so it shades corners, wall-and-post setups, and odd gaps a rectangle can't reach.

Layer them for scale and style
Overlap several triangles at staggered heights to cover a bigger area and get that architectural, sail-over-sail look.

Cool, fade-resistant Sunbrella
Breathable, solution-dyed fabric that vents heat and holds its color through years of direct sun.

Fabric Information

A triangle sail only needs three anchor points, which is why it fits places a rectangle fights. The build has to handle three-point tension cleanly.

Sunbrella canopy
Solution-dyed acrylic — color locked into the fiber for real fade resistance and years of true color in direct sun.

Breathable shade
The weave lets heat rise through and lets gusts pass instead of slamming into a sealed sheet, so the shade stays cool and the three corners take less abuse.

Reinforced tri-corners
All three corners are reinforced and fitted with heavy-duty D-rings so you can tension each point evenly. With only three anchors, even tension is everything — it's what keeps the triangle flat instead of hourglassing in the middle.

Water-repellent, not waterproof
Sunbrella sheds light rain, but this is a breathable, angled shade sail — built for sun and airflow, not for sealing a space against heavy rain.
