Key Seating Layout Standards

Every SHEF seating layout is developed in compliance with National Building Code (NBC) 2016 safety norms and international sightline geometry.

Center-to-Center Spacing (C/C)
530 mm - 580 mm

Standard auditorium comfort range ensuring natural elbow clearance and individual spatial autonomy.

Clear Egress Clearance
Min 400 mm (Tip-Up)

Gravity counterweight seat flip yields >400 mm clear passageway adhering strictly to NBC 2016 safety norms.

Stepped Riser Dimensions
Tread: 900 - 1,100 mm | Riser: 150 - 350 mm

Engineered to deliver optimal C-value sightlines (>90 mm) over preceding row headrests.

Radial Curve Radius
R 5,500 mm to R 25,000 mm

Calculated with custom wedge arm angles (2.5° to 6.0°) ensuring direct sightline focus to the proscenium focal point.
