TIPS ON MEASURING FOR CONCRETE


How you calculate the area for your estimate will depend on the shape - whether you have a rectangular, triangular, circular, or irregular area. See our pictorial guide below for guidance. (All measurements are in feet.)

Shape Formula Calculator Inputs
shape Enter the length and width of the area. (The area of a square is equal to the width times the length.) Length, Width
shape Enter the diameter of the circle. (The area of a circle is equal to Pi, or 3.1416, times the radius squared.) Diameter
shape Enter the base, length, and height. (The area of a triangle is equal to the base times the height, all multiplied by 0.5, or one-half.) Base Length,
Height
shape Enter the short diameter. (The area of a hexagon is equal to the short diameter squared, multiplied by 0.866.) Short Diameter
shape Enter the short diameter. (The area of an octagon is equal to the short diameter squared, multiplied by 0.828.) Short Diameter
shape Enter the sum of the lengths and sum of the widths, after graphing out the area. (One way to find the area of an irregular shape is to draw the shape on graph paper, allowing each square on the paper to represent 1 foot. (If you have a partial square, count it as one, rounding up.) Then, divide the drawing into rectangles. Add up the widths and lengths separately, and multiply the total sums together to find the area.) Length, Width
