Formula used
Area = length × width; order area = area × (1 + waste ÷ 100); square yards = order area ÷ 9
Worked square yards example
Square Yards Calculator example: 22.4 ft × 13.2 ft = 295.68 ft². With 10% allowance the order area is 325.25 ft², equal to 36.14 yd².
What the converted result represents
Use square yards for materials quoted by that unit, but round according to the package or roll layout rather than to a decimal area alone.
Limits of the geometric model
Roll width, seam layout, pattern matching, panel sizes, and irregular boundaries can require more product than an area conversion suggests.
