Staircase Setting Out: Why Attention to Detail Matters

As a builder, one of the components that demands precision and extra care is the staircase.

It's not just a means of moving between floors; it's a major element of safety, comfort, and design flow.

Unfortunately, in many buildings, stair halls are so narrow that even two people cannot walk side by side. This, combined with irregular risers and treads, creates discomfort and potential hazards for users.

One of the best ways to ensure a smooth and user-friendly staircase is by properly calculating the number of steps (risers) required from floor to floor before construction begins.

Professional Best Practices for Stair Riser Calculation.

Measure the Total Floor-to-Floor Height
Start by taking the full vertical measurement from the finished floor below to the finished floor above.

Divide to Determine Equal Risers.

Divide the total height by a riser height within the acceptable range (typically 145mm–175mm) to determine the number of risers. Round this to the nearest whole number, then recalculate the exact uniform riser height.

Maintain Uniformity.

All risers must be equal. Avoid situations where 19 risers are at 150mm and 1 or 2 risers end up at 175mm or 120mm. This inconsistency is a major safety concern and a sign of poor craftsmanship.

Don't start with Short First Steps.

Starting with a shorter base riser can disrupt the entire flight. It also affects your floor screeding level and may cause misalignment with landings.

Standards to remember.

Minimum Riser Height: 145mm
Maximum Riser Height: 175mm
Recommended Range for Comfort: 145mm to 155mm

Risers above 175mm or below 145mm create strain for users and increase the risk of accidents especially for children, the elderly, or in public-use buildings.

Final Thought
Whether you're working on a home, office, or public space, the staircase should be approached with the same level of attention as the foundation and other element in the building. A well-laid staircase is not just a feature — it’s a statement of safety and skill.
