# How To Measure

It is important to calculate the correct amount of square feet of sod needed for your lawn. We have provided some easy mathematics to help take some of the guess work out of measuring for your lawn.

**Measuring A Circle**

To calculate the area of a circle, first find the Radius. The Radius is a straight line from the center of a circle to the outside edge of the circle. Then multiply 3.14 times the radius times the radius again.

**Area = 3.14 x r ^{2}**

Let’s say the radius of your circle is 10 feet…

Area = 3.14 x 10^{2}

Area = 3.14 x 100

Area = 314 square feet

**Measuring A Rectangle or A Square**

To calculate the area of a rectangle or square, measure the length and width and then multiply together.

Area in square feet = Length in feet (L) x Width in feet (W)

**Area = L x W **

Let’s say your length is 20 feet and your width is 30 feet…

Area = 20 feet x 30 feet

Area = 600 square feet

**Measuring A Triangle**

To calculate the area of a triangle, measure the base and the height (both in feet). Then multiply the base and the height together. Divide the result by 2 to get the area.

Area = ( Base (B) x Height (H) ) ÷ 2

**Area = (B x H) ÷ 2**

Let’s say your base is 30 feet and your height is 20 feet…

Area = (30 x 20) ÷ 2

Area = 600 ÷ 2 A = 300 square feet

**Freeform Measuring – Putting It All Together**

Break the freeform area into regular geometric shapes and calculate the area of each shape. Add the area of each shape together to figure the total square feet. Once you’ve done that, use our Sod Calculator to estimate your investment.

**Total Area = Circle (1) + Rectangle (2) + Square (3)**

Let’s say your circle is 314 square feet, you rectangle is 100 square feet and your square is 600 square feet…

Area = 314 + 100 + 600

Area = 1014 square feet
