📐 Key elements of staircase measurement

• Staircase height – measure the height from the 1st‑floor finished floor to the 2nd‑floor finished floor. This is the most important measurement, as it determines the number of steps and the step rise.
• Stair opening length – shows how much horizontal space is available for the staircase. This is essential when choosing the staircase shape (straight, U‑shaped, L‑shaped).
• Stair opening width – determines the maximum width of the staircase and the placement of the handrail.
• Floor slab thickness – affects how the top step connects to the upper floor.

🧭 Step‑by‑Step: how to measure a staircase

• Use a tape measure or a laser measurer
• Record all measurements with millimetre accuracy
• Take photos of the stair opening if needed
• Check for obstacles in the opening (beams, posts, sloped ceilings)
