Stair Math: Converting 354 Steps into Flights

A standard residential staircase averages 12–15 steps per flight (typically 13–14 for 7¾" rise / 10" run, 8–9 ft ceiling). Using a median of 14 steps:

354 ÷ 14 ≈ 25.3 flights.

Contextualizing the Climb

• Empire State Building: 1,576 steps (86 flights) to the 86th floor.
• Eiffel Tower (stairs to 2nd floor): 674 steps (~48 flights).
• Typical 10-story office building: ~20–22 flights.
• 354 steps: Roughly a 17–18 story building climb. A serious cardio workout (burns ~15–20 kcal for 70 kg person).

Variables: Commercial codes allow up to 16–18 steps/flight (lower rise). Grand staircases may have 20+. Always count the specific stair in question for precision.
