What is needed to measure the areas you would like to replace with new sod?
1. A piece of paper and pencil (highly recommend a pencil instead of pen).
2. Measuring wheel or tape measurer. Home Depot Measuring Wheel >
4. The formulas listed at the bottom of this page.
Once you have everything needed to measure the areas for new sod, go out and sketch the areas on a piece a paper. After you are finished sketching the areas, measure those areas (rectangle, square, triangle or circle). Use the formulas below to help determine what type of measurement is needed. Lastly, always add on an extra 10% of sod for cutting and edging. It's better to have extra than having to go out and buy expensive pieces of sod.
Square or Rectangle:
To figure the area of a square or rectangle, measure the Length & Width and multiply them together.
Length x Width = Area
Example: 12 x 24 = 288 sq.ft.
A Right Triangle has one 90º corner. To figure the area of a right triangle, multiply the two sides that contact the right angle and divide by 2
Length x Width / 2 = Area
12 x 24 = 288 ÷ 2 = 144 sq.ft.
Circle, 1/2 Circle, 1/4 Circle:
To figure the area of a circle, take the radius times the radius, then multiply by 3.14. Radius is a straight line from the center of a circle to the outside of the circle.
(Radius x Radius) x 3.14 = Area
6 x 6 = 36 x 3.14 = 113 sq.ft.
Half Circle divide by 2
6 x 6 = 36 x 3.14 = 113 / 2 = 56.5 sq.ft.
Quarter Circle divide by 4
6 x 6 = 36 x 3.14 = 113 / 4 = 28.25 sq.ft.
