How to measure floor-to-floor height
Measure from finished lower floor to finished upper floor. If finishes are missing, add their designed build-ups separately and record the assumptions.
ReadGuides to stair dimensions and geometry
Detailed explanations of measurements, 2h+s, pitch, headroom, layouts and floor build-up.
How to use the 2h+s formula
The 60–65 cm range relates rise and going. It does not replace flight-width, headroom or local-code checks.
ReadRiser count versus floor height
Riser count must be an integer. Adding or removing one riser can materially change run and pitch.
ReadHow to choose stair going
Assess going together with rise. A large tread alone does not guarantee comfort when walking rhythm is poor.
ReadStair pitch angle
Pitch follows from rise and going. Steeper stairs are shorter but harder to descend and use while carrying items.
ReadStair headroom
Minimum headroom often occurs at the edge of the floor opening. Check it along the walking line including slab and finishes.
ReadL-shaped or U-shaped stairs
An L layout extends in two directions, while a U layout organises parallel flights. Compare footprint, landing and circulation.
ReadLanding or winders
A landing provides a predictable rest area. Winders save space but require walking-line checks and precise execution.
ReadHow to measure the floor opening
Record length, width, edge position, slab thickness and any beams. Do not confuse finished clear dimensions with structural dimensions.
ReadFloor build-up and stair rises
Flooring, adhesive, finish and levelling alter the first and last rise. Include them before construction.
