# 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
