Staircase Geometry & Spindle Spacing Tool

Design your staircase with confidence. This toolkit calculates the essential Rise & Going dimensions for comfortable, safe steps and works out the exact Spindle Spacing required to meet UK Building Regulations (Approved Document K).

Need help with Winders, Landings, or Layouts?

Calculations are only the first step. While this tool gives you the perfect Rise for your staircase, calculating the geometry for Winder turns (triangular steps) and kite sections is a complex specialist task.
