Safety Guidance
Maintain strict non-combustible clearance around fire zone.
Fuel type and pit size both influence the minimum clearance area around active flames.
Balanced spacing helps maintain warmth while preserving safe circulation around the fire pit.
Comparing safety diameter with patio limits prevents unsafe layouts before purchase or install.

The calculator combines fire pit diameter, seating offset, and fuel-adjusted safety buffer to estimate a minimum recommended safety diameter, then compares it to available patio dimensions.
