How Much Glass Do I Need?

Pick a calculator, fill in info, then click "Calculate."

Rectangular Area to Cover or Volume to Fill
Length of area to cover/fill:
Width of area to cover/fill:
Depth of area to cover/fill:
If you are covering an area we suggest 1 to 2 inches deep.



Vases & Other Odd Volumes to Fill
# of containers you are filling:
Fill a container with water to determine the volume you need.



You will need about 7 pounds per square foot to cover to a depth of 1 inch. If you measure the width and depth of the area you want to fill in feet, and know how many inches of fill you want, the weight of the glass needed is Width x Depth x Fill x 7. For example if you want to cover a 2.5 x 10 foot area with glass to a depth of 3 inches, you would need 2.5x10x3x7, or 525 pounds of glass. If you wanted to fill a 4x1 foot fish tank (such as a 55 gallon tank) to a depth of 2 inches, you would need 4x1x2x7, or 56 pounds of glass. Using the calculator at the top of this page will figure that - be sure to select feet or inches as appropriate.

For small areas, measuring in inches might be more practical. You need about .0486 pounds per inch per square inch of area. If you measure your area in inches, the weight of the glass needed is Width x Depth x Fill x .0486. If you want to fill a 4 x 4 inch square vase to a depth of 3 inches, you would need 4 x 4 x 3 x .0486, or 2.33 pounds of glass. (If you needed to fill 12 vases for table centerpieces, you would need 2.33 x 12 = 28 pounds of glass.)

If you are filling irregular shaped vases or other containers, try filling one with water (only up to the point where you want the glass to go)and then measure that volume by whatever method is conveniant. You can enter that volume (the calculator can measure volume in fluid ounces, cups, pints, quarts, gallons, mililiters and liters) and the total # of containers you want to fill at our "Vases and Other Odd Volumes to Fill" Project Calculator above to determine how much product you need.
