01
Every dimension is editable
Enter the height and run lengths, position the landing, and set the dimensions of stringers, treads, nosing and risers. Everything can be adjusted.
From measurements to a buildable staircase
Building a staircase?
Whether you are building it yourself or hiring professionals, good decisions are easier when you can see the options before construction begins.
Why Staircase3D exists
How much space does a staircase need?
When I was building my own house, I discovered how difficult it was to know how much space the staircase actually needed. Should it have a landing, or would a spiral staircase fit better?
The questions quickly became practical: How do you avoid hitting your head on the flight above? How far can the flights be offset without compromising headroom? And how do you know the stringer will not come down so low that it blocks a door?
I could not find a tool that let me test all of this with my own measurements. That is why I created Staircase3D — a staircase generator that calculates, lets you adjust and shows the staircase in 3D before you build.
Welcome to what may be the world's most advanced staircase generator in your pocket.
Plan before you build
Headroom, building standards and details — together in 3D.
See how the staircase fits the building, not just how it looks. Staircase3D brings calculations, drawings and 3D visualisation into one workflow.
02
Intuitive and fast
The app was designed with one goal: to make the digital interface easy for anyone to use and get started with their own staircase quickly.
03
Optimise automatically or use fixed step dimensions
Switch between automatic staircase optimisation based on total height and overall run length, or lock the tread depth and riser height to fixed dimensions.
04
Drawings
Create dimensioned production and assembly drawings based on the staircase you have generated.
05
Stringer types
Choose between different stringer types and adjust the stringers to the structure and look you want.
06
Floor thickness
Include the construction between floors when calculating the opening, connection and headroom.
07
Headroom
Check the clearance below the flight above, so steps and openings never end up at head height.
08
Building standards
The app is kept up to date with current staircase regulations and uses a clear traffic light to show whether the staircase is valid or not.
Precision without friction
From millimetres to feet and inches.
Choose the measurement system that fits the project. The same detailed 3D model stays with you throughout.
Metric and US Imperial
Work in millimetres, centimetres and metres, or use feet and inches with fractions. Measurements remain consistent throughout the project.
Powerful 3D graphics with Metal
Metal-based rendering makes it fast to rotate, zoom and evaluate complex staircase designs directly on your Apple device.
