- Straight direction: No winding or curved stairs.
- Number of steps: Minimum 3, maximum 12 per flight.
- Minimum free width: 1.20 meters (excluding handrail protrusion).
- Tread dimensions: Minimum 28 cm.
- Rise dimensions: Between 13 cm and 17.5 cm, consistent within each flight and minimal difference between flights.
- Step formula: 54 cm ≤ 2 × rise + tread ≤ 70 cm.
- Riser piece: Required, no projections.
- Angle: 75° to 90°.
- Nosing: Not allowed.
- Marking: Contrasting 5 cm strip on each tread.
- Stairs should have landings between flights, with a minimum depth of 1.20 meters. The stairs should be well-lit and have handrails on both sides.
