사용 방법
- 아래층 바닥에서 위층 바닥까지의 '전체 높이'를 측정합니다.
- 원하는 챌판 높이와 디딤판 깊이를 입력합니다.
- '슬래브 두께'를 설정합니다. 이는 계단 아래의 구조 콘크리트 두께입니다.
- 계산기가 정확한 계단 수와 필요한 콘크리트 양을 결정합니다.

가이드 및 정보
Use this calculator for a straight concrete stair flight. It estimates the stair shape and concrete volume, but it does not replace local code checks or structural design.
What the estimate includes
The tool estimates a straight stair as step triangles plus the sloped waist slab. Landings, beams, side walls, reinforcement, formwork, and waste are not included.
Step count
Total rise divided by target rise, rounded to a whole step count.
Exact rise
Total rise divided by the rounded step count.
Concrete volume
Triangular step area plus sloped waist slab area, multiplied by stair width.
Cost
Estimated concrete volume multiplied by your price per volume.
Practical examples
House stair check
Try a 2800 mm rise, 175 mm target rise, 250 mm tread, 1000 mm width, and 150 mm waist thickness to estimate a compact residential-style flight.
Compare a deeper tread
Increase the tread depth and save the calculation. The concrete volume and floor run will grow, but the stair may feel less steep.
Budget a wider stair
Change only the stair width to see how volume and cost scale for a wider flight.
Common mistakes
Measuring unfinished floors
Use finished floor levels when you know them. Floor finishes can change the real rise and make the first or last step uneven.
Treating the warning as approval
The warnings are quick checks only. Stair rules differ by country, building type, and local authority.
Forgetting landings and waste
The estimate is for the straight flight only. Add landings, edge beams, waste, and delivery minimums outside this tool.
Guessing waist thickness
Waist thickness affects volume and structure. Use the value from your drawing or ask an engineer for structural work.
Tips
Save each option
Save a few rise and run options so you can compare comfort, footprint, concrete volume, and cost.
Check the angle early
A steep angle can save space but may be uncomfortable or fail local rules. Adjust rise and run before pricing material.
Order with a margin
Concrete estimates are based on clean dimensions. Real pours often need extra for uneven ground, form losses, and ordering rules.
