Ngenai kalkulator iki

A stair calculator lays out a staircase from the total vertical rise (floor to floor) and the tread run (the horizontal depth of each step). It divides the total rise by a comfortable target riser height — about 7 inches — to find a whole number of risers, then recomputes the exact riser so every step is equal in height, which building codes require. The number of treads is one fewer than the risers (the top riser lands on the upper floor), the total horizontal run is treads × tread depth, and the stringer length is the diagonal √(rise² + run²).

Worked example: a 108-inch floor-to-floor rise divided by a 7-inch target is 15.4, rounded to 15 risers, giving an exact riser of 108 ÷ 15 = 7.2 inches. That means 14 treads; at a 10-inch run the total run is 140 inches and the stringer is √(108² + 140²) ≈ 176.7 inches. The 2R+T check is 2 × 7.2 + 10 = 24.4 inches — right in the comfortable 24–25 inch range.

It flags whether the riser stays within the common code maximum of 7¾ inches and checks the comfort rule, so carpenters and DIY builders can size a stair, cut stringers, and confirm it will pass inspection before cutting timber.
