Bulk Stone Calculator

How It Works

First, measure the length in feet, width in feet, and depth in inches of the space you want to fill. Then, choose a product in the calculator. It will provide you with an estimated total in tons required to fill that specific space.

To do the calculation yourself:
				
					Cubic Yards = (length (ft.) * width(ft.) * (depth(in.)/12) / 27)

Total Weight = Cubic Yards * (Tons/Cubic Yard)

				
			
				
					
Ex: You have a 10 ft. x 10 ft. x 3 in. area to fill with gravel

0.93 Cubic Yards = (10 * 10 * (3 / 12)) / 27

Total Weight = 0.93 * 1.4 = 1.30
				
			

If your area is an irregular shape, divide it into various rectangles and add the totals together to get a rough estimate of the total tons required.
