Planning a stunning fire pit or fireplace? Our Fire Glass Calculator helps you accurately determine how much fire glass you'll need. Avoid overspending or under-ordering for your rectangular or round fire feature. Get a precise estimate in pounds for a dazzling display.
Formula:
The calculator uses industry-standard approximations to estimate the fire glass required in pounds (lbs).
- For Rectangular/Square Fire Pits:
Weight (lbs) = (Length (in) × Width (in) × Depth (in)) / 20 - For Circular Fire Pits:
Weight (lbs) = (Diameter (in) × Diameter (in) × Depth (in)) / 40
Where:
- Length, Width, Diameter: Dimensions of your fire pit in inches.
- Depth: Desired depth of the fire glass in inches (typically 1-3 inches for optimal flame).
