Final answer:
The handrail height is typically between 34 and 38 inches, measured vertically from the stair tread nosing to the top of the handrail for safety and usability in building design.
Step-by-step explanation:
The question is asking about the standard height for a handrail on a staircase.
While the exact height can vary by jurisdiction, a typical range is between 34 and 38 inches measured vertically from the leading edge of the stair tread nosing to the top of the handrail. It's important for the height to be consistent to prevent accidents and ensure stability for users.
This measurement is important in construction and building design for ensuring the safety and usability of staircases.
