BalustradeCalc checks baluster gap spacing only. It does not constitute a compliance assessment. Balustrade installations must comply with all relevant requirements of the NCC, applicable Australian Standards, and local regulations, including but not limited to height, climbability, structural loading, and bottom rail clearance. Always verify with your building certifier. This tool assumes vertical (plumb) balusters.
