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
