## Description

Type your total rise — get every buildable stair, drawn to scale and checked against your building code. No ads.

The stair calculator that starts from what you actually know: the total rise.

Measure floor to floor, type it in, and StairSketch instantly lists every buildable riser count — drawn to scale on a live blueprint diagram, ranked by comfort, and checked against your residential building code.

SOLVE ANY STAIR IN SECONDS
• Enter the total rise — 8' 2 1/2", 98.5, 2500 mm, 2.5 m all work
• Get every option: riser height, going, treads, total run, pitch, stringer length
• Tap any riser count to compare; the diagram redraws live
• Need to land before a wall? Limit the total run and options adapt

PASS THE BUILDING CODE CHECK
• United States — IRC residential limits
• United Kingdom — Approved Document K
• Canada — NBC  •  Australia — NCC
• Every check shown with the exact numbers, pass or fail
• Comfort ranking with the classic 2R+G stride rule

CUT STRINGERS RIGHT THE FIRST TIME
• Cut list: how many 2x12 stringers, stock length to buy, tread and riser boards
• Fractions to 1/16" or millimetres — your choice, everywhere

KEEP EVERY JOB IN YOUR POCKET
• Save projects and reopen them on site
• Export a one-page PDF plan with the diagram and cut list (Pro)

FREE, WITH AN HONEST PRO UPGRADE
The calculator is free forever, with no ads. StairSketch Pro adds unlimited saved projects and the PDF plan export — as a one-time lifetime purchase or an annual plan with a 3-day free trial. Cancel anytime in your App Store settings. Your saved projects stay viewable forever, subscribed or not.

Stair measurements are reference values — always verify against the building code in force in your jurisdiction.
