How do I measure for the right size of metal stairs?

To measure for the right size of metal stairs, follow these detailed steps to ensure accuracy.

Key Measurements

Overall Height: Measure vertically from the finished floor or landing at the bottom of the metal stairs to the finished floor or landing at the top. This will give you the total rise of the staircase.

Overall Length: Measure the horizontal distance from the edge of the nosing on the first tread at the bottom to the edge of the nosing on the upper landing. This measurement is crucial for determining how much space your metal stairs will occupy horizontally.

Tread Depth (Run): Measure the depth of each tread from front to back. This is important for comfort and safety, as it determines how much space there is for foot placement.

Riser Height: Measure the vertical height from the top of one tread to the top of the next tread. This should be consistent across all risers for uniformity.

Nosing Length: If applicable, measure how far each tread extends past the riser below. The nosing contributes to safety by providing additional foot placement area.

Count Risers and Treads: Count all risers, including those between landings, and count treads excluding landings. Typically, there is one fewer tread than risers.

Stair Width: Measure from edge to edge of each side of the tread, ensuring it meets building code requirements (usually a minimum of 36 inches).

Additional Considerations

Building Codes: Be aware of local building codes regarding maximum riser height (generally no more than 7.75 inches) and minimum tread depth (usually at least 10 inches) to ensure safety and compliance.

Headroom: Ensure there is sufficient headroom above the metal stairs, typically a minimum of 6 feet 8 inches, to allow comfortable passage.

Material and Design: Consider what material (steel, aluminum) you will use for your metal stairs and whether you want a straight, spiral, or floating design, as this may affect measurements and installation methods.

By following these guidelines and taking precise measurements, you can ensure that your metal stairs will fit correctly and meet safety standards.
