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 yardage of a rectangular 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 necessary square yardage of the material, as well as its cost.

How to Find Square Yards

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

To calculate square yardage, you must first convert your measurements to yards. You can use our length converter for a quick conversion, or, if you already know the area in sq ft, use our square feet to square yards calculator for instant results.

Diagram demonstrating that 1 square yard is equal to a 3 ft x 3 ft square, or 9 sq ft.

Use these steps to calculate the area of a rectangular space in 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 = lengthyds × widthyds

How to Find Square Yards Using Measurements in Feet

The steps above guide you to convert all measurements to yards before multiplying, but it’s possible to find square yards after multiplying 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 the area in square feet
  • Divide the area by 9 to find square yards.

sq yds = (length ft × width ft) ÷ 9

Formulas to Find Square Yards

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


sq yds = lyds × wyds

sq yds = lft × wft ÷ 9

l = length
w = width

You can also use our rectangle area calculator.

Rectangular Border

sq yds = (lyds × wyds) – (ayds × byds)

sq yds = ((lft × wft) – (aft × bft)) ÷ 9

l = outer length
w = outer width
a = inner length
b = inner 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. You can also use our circle calculator to find the radius.

Diagram of a circle showing r = radius


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

Frequently Asked Questions

How many square yards is 12 feet by 12 feet?

An area that is 12 feet by 12 feet is equivalent to 144 square feet or 16 square yards.

What’s the difference between square meters and square yards?

While square meters and square yards are both units of area, the former is part of the metric system of units, while the latter is part of the imperial system. They are similar units, but do differ by almost 20%. For example, one square meter equals roughly 1.196 square yards.

What is measured in square yards?

Any area can be measured in square yards, but typically square yardage is used in housing, landscaping, and agricultural projects. It’s also commonly used to measure flooring and textiles.
