Fire Glass Calculator

Use our fire glass calculator to determine how much fire glass you will need to fill your fireplace or fire pit. Just measure your fire feature in inches and fill out the dimensions below and click calculate to get an accurate measurement of how much fire glass you need.

We recommend 2-4 inches of total glass depth for most fireplaces and fire pits. Allow 1-2 inches of glass to cover the burner. It is important to not overfill!
