Triangular shade sails are sized by measuring each side of the triangle from corner to corner. For example, a 10’ × 10’ × 10’ sail is an equilateral triangle with all three sides measuring 10 feet, while a 10’ × 14’ × 14’ sail is an isosceles triangle with one shorter side and two longer sides.
All dimensions shown are nominal corner-to-corner measurements before installation tensioning and do not account for mounting hardware, attachment clearances, or required installation gaps. Shade sails are designed to be installed under tension and require adequate space between each sail corner and the mounting point for proper hardware, adjustment, and long-term performance.
As a general guideline, we recommend allowing approximately 5%–10% of the sail dimension for tensioning clearance at each corner. For example, a 10’ sail side should typically have 6”–12” of additional space per corner, while larger sails may require 12”–24”+ depending on hardware configuration, mounting conditions, and desired tension. Insufficient spacing can make installation difficult and may prevent the sail from being properly tensioned, which can lead to sagging, fabric flutter, or excessive stress on mounting points.
Mounting hardware is sold separately and is not included with the shade sail unless otherwise noted. Hardware requirements vary based on installation type, mounting structure, and span distances. If you are unsure about sizing, mounting clearances, or hardware requirements, we recommend contacting us before ordering to confirm fitment for your application.
