Tips on Measuring for Concrete
To estimate how much concrete your project requires, enter your project area measurements—rounded to the nearest foot. The chart below will help you determine which measurements to make based on the shape the area in consideration.

Shape	Formula	Calculator Inputs
	Multiply Length by Width	Length, Width
	Square the circle's radius; multiply by 3.1416.	Diameter
	Halve the base length; multiply by height. Or, multiply the base length by the height and divide by 2.	Base Length, Height
	Square the short diameter; multiply by .866.	Short Diameter
	Square the short diameter; multiply by .828.	Short Diameter
	Draw the project out on graph paper, with 1/4 inch representing 1 foot. Count up the number of squares. Partial squares count as one.	Length, Width
