Using the Square Yardage Calculator

This calculator makes short work of figuring out the square yardage of any area for all your construction, landscaping, and craft projects, such as carpet, flooring, tiling, drywalling, gardening, and even sewing.

To quickly find the square yards contained in your area, simply enter the length and width of your rectangle into the calculator above. Use any units, imperial or metric. To estimate costs, enter the price per sq yd. The calculator will instantly give you the square yards you need and the cost of the material.

How to Find Square Yards

Square yardage is a common measurement of area, measured in yards, and is used in many fields. One square yard is equal to 9 square feet, or an area that is three square feet wide by three square feet long.

To calculate it, you must first convert your measurements to yards. You can use our conversion calculators for quick conversions. Or, if you already have your area in sq ft, use our square feet to square yards calculator for instant results.

This diagram demonstrates that 1 square yard is equal to a 3 ft x 3 ft square, or 9 sq ft

Use these steps to calculate square yards.

  • Measure the length and width of each side of the rectangle
  • Convert these measurements to yards as described above.
  • Multiply the length times the width to get the area measurement in sq yds.

sq yds = length yds × width yds

How to Find Square Yards Using Measurements in Feet

The steps above guide you to convert all measurements to yards first, but it’s possible to find square yards if all of your measurements are in feet too. Follow these steps if all of your measurements are in feet.

  • Multiply the length in feet times the width in feet to find square footage
  • Divide the square footage area by 9 to find square yards.

sq yds = (length ft × width ft) ÷ 9

Formulas for Square Yards

The following formulas show how to calculate square yards for various shapes. Formulas to find area given measurements in yards and in feet are provided to simplify conversion.


sq yds = lyds × wyds
sq yds = lft × wft ÷ 9

l = length
w = width

Rectangular Border

sq yds = (lyds – (2 × byds)) × (wyds – (2 × byds))
sq yds = (lft – (2 × bft)) × (wft – (2 × bft)) ÷ 9

l = outer length
w = outer width
b = border width

sq yds = πryds2
sq yds = πrft2 ÷ 9

r = radius
π = 3.14159265359

If you know the diameter of the circle you can find the radius by dividing the diameter in half.

s = 1/2(ayds + byds + cyds)
sq yds = s(s – a)(s – b)(s – c)

s = 1/2(aft + bft + cft)
sq yds = s(s – a)(s – b)(s – c) ÷ 9

a = edge a
b = edge b
c = edge c
