# Measuring

As a premier sod grower at Dunteman Turf Farms we are able to provide our clients with unmatched sod, grass seed and turf services to clients located throughout Elburn, DeKalb, St. Charles, Geneva, Aurora, Naperville, Elgin, Yorkville and surrounding areas of Illinois. Dunteman Turf Farms was created with the promise to put clients first with excellent service. We have provided a few helpful tips and measurements to get you through the process. Before ordering sod for your new lawn you must figure the square footage of sod needed. To make the calculation simple, this can often be reduced to a series of squares and rectangles. Using the following formulas on this site will make the task easy and give you an accurate count of square feet needed.

### Square or Rectangle

Area = width x length
Determining the area of a square or rectangle is simple. When measuring, determine the length and width of your area. You then multiply the length by the width for the amount of sod needed.

### Circle

Area = 3.14 x radius²
To determine the area of a circle, you first need to find the center point of your circle. You then measure from the center to the edge of the circle, which is the radius of the circle. You need to multiply this number by itself (square it), and then multiply by 3.14 (Pi).

### Oval

Area = 3.14 x radius 1 x radius²
Determine the area of an oval is similar to determining the area of a circle. With an oval however, you will have to determine the radius twice – once from the center to the close end, and then again to the far end of the oval. You take each radius multiply by 3.14 (Pi).

### Square Triangle

Area = (base x height)/2
A square triangle is a triangle that has a right (90°) angle. To determine the area, measure the base of the triangle and the height of the triangle. These are the “legs” of the triangle that form the right angle. After multiplying the base by the height, you divide that total by two to determine the area of the triangle. You do not need to measure the third leg of the triangle.

### Irregular Triangle

An irregular triangle is a triangle with no right angles. You first need to divide your triangle into right triangles, and using the formula above, determine the area of each triangle. After determining the area of each triangle, you then add the two totals together for the total area of your irregular triangle.

### Trapezoid

Area = (height x (base 1 + base 2))/2
A trapezoid takes a bit of work to determine the area. You first need to measure the “top” and “bottom” (base 1 and base 2). Then, measure the distance between the two, to determine the height of the trapezoid. Add base 1 and base 2, and then multiply by the height of the trapezoid. You then divide this number by two to determine the total area of your trapezoid.

### Unusual and Irregular Shapes

These are what most yards are-unusual and irregular. It is important that you sketch out the area to be sodded, including any areas (decks, sheds, pools) where there will not be any sod.

Break your sketch into shapes-rectangles, circles and triangles. Determine the area for each of the shapes and add them together. Also determine the area not being sodded-you need to subtract this from your total area.
