Stair & Tread Calculator
Measure floor to floor and this works out the whole stair - risers, treads, the run it needs, and the parts for the system you choose.
Enter the total rise in inches, pick the tread width and the stair system. Add a landing if you want one - a tall rise gets one automatically.
Tread and riser counts, the total run, a by-the-part list with every quantity editable, and the matching stair kits with prices.
Based on a 7¾-inch max riser and 10-inch treads (common residential code). Materials ship as lengths — stringers and treads get their final cuts on site. The longest stringer we can supply is 16 ft; a taller rise plans as two flights with a landing — or add a landing by choice on any stair.
Build it by the part
Real part SKUs, live prices — and every quantity is editable, because hardware differs by build. Adjust to yours; we confirm the final list by phone.

Tread stock sells in 12-ft lengths and treads are cut to width on site; stringers top out at 16 ft (a taller rise plans as two flights with a landing). The square-timber systems are quoted by phone for now — their stringer and tread listings are being set up.
