Anatomy of Stairs

The Rise and Run Dance

Stairs perform a dance of rise and run, where the rise is the vertical height between two consecutive steps, and the run is the horizontal distance. Striking the right balance ensures a comfortable climb.

Types of Stairs

Spiral Stairs

A stylish space-saver, spirals add a touch of whimsy and are perfect for compact environments.

L-Shaped Stairs

A versatile design that fits well into both large and small spaces, offering a practical turn.

Materials Matter

Stairs come in various materials, from classic wood to sleek metal. The choice influences both aesthetics and durability.

Stair Math: Calculating the Perfect Ascent

Calculating stairs might sound daunting, but fear not! The Stair Math 101 table breaks it down:

Total RiseOverall height from start to end
