What is the minimum or maximum riser height?

The maximum riser height for stairs, according to most building codes, is typically 7.5 to 8 inches (about 19 to 20 cm), while the minimum riser height is usually around 4 inches (about 10 cm). These measurements ensure safety and accessibility. It's important to check local building codes, as they can vary by region. Consistent riser heights within a flight of stairs are also critical to prevent tripping hazards.
