The riser is the vertical component between each tread on a staircase, supporting the tread above and contributing to the stair’s overall structure.
Benefits:
- Structural Support: Provides important support for the treads, maintaining the staircase’s integrity.
- Consistency: Ensures uniform step height for a smooth and safe ascent or descent.
- Safety: Contributes to a stable and predictable walking surface, reducing the risk of tripping.

Measure from the top of one tread to the top of the next tread to ensure consistency and safety.
OSHA Compliance for Risers:
The Occupational Safety and Health Administration (OSHA) provides guidelines to ensure risers meet safety standards. Key points include:
- Height Consistency: Maintain uniform riser heights to prevent trips and ensure safe stair usage.
- Strength Requirements: Ensure risers can support the weight and stress placed on them during regular use.
- Regular Inspections: Conduct frequent checks to verify structural integrity and compliance with safety standards.
