Stair Calculator: Stringer Cut
Rise, Run & Dimensioned Plan
Only for iPhone
$1.99 · Designed for iPhone. Not verified for macOS.
iPhone
Type one measured height and your staircase designs itself — risers, treads, stringer cuts and a dimensioned drawing.
Every set of DIY stairs starts with the same puzzle: one total height,
and the question of how many steps should divide it.
StairStepScan answers it on the spot. Measure the rise with a tape,
type it in, and the app splits it into even risers, pairs them with
a comfortable tread, and draws the whole staircase as a dimensioned
side profile you can build from.
PLAN
- Riser and tread worked out from one measured height
- Compare step counts side by side, with the classic 2R+T comfort
rule showing which option walks best
- Slope angle and stringer length, drawn right on the diagram
BUILD
- A cut list in plain carpentry terms: stringer notches, tread
boards, riser boards
- Millimeters or feet-and-inches with proper fractions
- Save every staircase — the deck steps, the shed, the basement
HONEST TOOL
- Comfort ranges are editable defaults, not building law. Stair codes
differ by region, and the app tells you to check yours before you cut.
No account, no subscription. One purchase, on your device, forever.
