To determine exactly how much fire glass you will need for your fire feature, use our accurate fire glass calculator below. Simply add the dimensions of the area that you want fire glass in, hit calculate, and our calculator will tell you approximately how much fire glass you will need.
Example: If your fireplace had a front width (A) of 36", a back width (B) of 24", a depth (C) of 15", and you wanted a 3" height (D) of fire glass to cover the entire fireplace floor, then you would buy about 70 pounds of fire glass.
Please note that when using fire glass with propane gas, you should not cover your burner in more than 1" of glass. This ensures your flame receives enough oxygen.
We realize this might seem like a lot, but remember that glass is heavy. Once the fire glass disperses over an area, it doesn’t go as far as one might think.
