What are the Standard Rise and Going for Stairs in the USA?
Brief Summary
In the USA, building codes typically mandate a stair rise (vertical height between steps) of between 6 to 7.75 inches, with 7 inches being the most common standard. The going (horizontal depth of each step) is typically between 10 to 11 inches. These measurements ensure stairs are safe and comfortable for most people to use.
Rise
- Definition: The rise refers to the vertical height between the treads of consecutive steps.
- Standard Range: In the USA, building codes generally specify a maximum rise of 7.75 inches and a minimum rise of 4 inches. However, most residential stairs have a rise between 6 and 7 inches.
- Ideal Rise: A rise of 7 inches is considered the most comfortable and standard for residential stairs.
- Code Compliance: Adhering to the local building codes is crucial for safety and ensuring your staircase passes inspections.
Going
- Definition: The going is the horizontal depth of a stair tread, measured from the front edge of one tread to the front edge of the next.
- Standard Range: The standard going for residential stairs typically falls between 10 and 11 inches.
- Ideal Going: A going of 10 inches is often considered ideal for comfortable and safe use.
- Relationship with Rise: The rise and going are interconnected; adjusting one will affect the other. The general rule is that the sum of one rise and one going should be approximately 17 to 18 inches.
Other Considerations
- Headroom: The vertical clearance above the stairs, typically at least 6 feet 8 inches, is essential for avoiding head bumps.
- Stair Width: The minimum width for residential stairs is usually 36 inches, but wider stairs are generally more comfortable and safer, especially in high-traffic areas.
- Handrails: Handrails are required on most staircases for safety and should be installed at a comfortable height.
Building Codes and Regulations
Building codes and regulations regarding staircases vary across different states and municipalities in the USA. Always consult your local building codes before designing or constructing a staircase. Failure to comply with these codes can lead to safety hazards and potential legal issues.
Remodeling and Staircase Design Trends
While standard rise and going measurements are crucial for safety and functionality, there’s room for creativity in staircase design. Modern trends lean towards open-riser stairs, floating stairs, and the use of mixed materials like glass and metal alongside traditional wood. However, any design choices should prioritize safety and adhere to building codes.
Remember, staircases are a significant part of any home, both functionally and aesthetically. Understanding the standard rise and going, along with relevant building codes, is essential for designing or remodeling a staircase that is safe, comfortable, and visually appealing.
