Stadium seating must be designed for structural safety, comfortable viewing, safe circulation, accessibility, and proper crowd movement. The dimensions shown are typical educational values and must be verified against the applicable local building, fire, accessibility, and stadium standards before construction.
Key details:
Typical riser height: 400 mm
Typical row spacing / tread depth: 800 mm
Minimum aisle width: 1200 mm
Seat pan height: approximately 430 mm
Seat depth: approximately 430 mm
Backrest height: approximately 350 mm
Handrail height: approximately 1100 mm
Maximum handrail post spacing: 1200 mm
Handrail: Ø50 mm stainless steel or approved equivalent
Intermediate rail: Ø25 mm
Seat: UV-resistant blow-molded plastic
Support: MS/approved metal bracket, securely bolted to the concrete step
Concrete: C25/30 minimum, subject to structural design
Handrail base plate: 200 × 200 × 10 mm
Anchorage: chemical anchors sized and designed for the required loads
Provide accessible seating and compliant routes where required.
⚠️ Important: These are illustrative design dimensions, not a construction specification. Final riser/tread geometry, structural reinforcement, handrail loads, anchorage, egress, sightlines, and accessibility must be checked by a qualified engineer against the applicable code.
