The Anatomy of a Staircase: Everything You Need To Know

The Anatomy of a Staircase: Everything You Need To Know

We use staircases daily and never really question how they are put together. They are useful, taking us where we need to go and often act as a lovely statement in our homes. Let’s discuss everything you need to know about the anatomy of a staircase to help you decide if you should build or repair your own.

What Are Staircases Made Of?

Treads, Nosings, and Risers

Tread

As you walk up and down the stairs, your feet land on the treads. The tread is the horizontal piece across each step made for stepping on. Treads should be covered in non-slip paint, runners, or carpet to keep users safe.

Nosing

The nosing is the small overhang at the front of each tread. It is usually rounded and adds a nice finish to the treads, and it also offers a little bit more space for stepping.

Riser

The riser is the vertical piece directly under each nosing and tread.

Railings, Posts, Balusters, and Shoes

Balusters, posts, and the rail are all part of a staircase’s railing system. The entire railing system serves the purpose of safety and added stability, and each part plays an important role.

Rail

The rail is what we put our hand on for added balance and security as we go up and down the stairs. It is often attached to the wall at the top and bottom of the staircase.

Post

Posts (or newel) connect the stairs or the floor—depending on the placement and design—to the railing system.

Baluster

Balusters consist of wood or metal and come in a rounded or squared shape. They are placed strategically in between the posts of a staircase for added safety and support.

Shoe

The shoe is the part of the staircase that holds the balusters in place.

Stringers

The stringer provides support when a staircase is built, so it isn’t up to only the drywall to support it. The stringer is anchored to a stud, which, in turn, anchors the staircase to the stringer.

Mr. Spindle is here to share everything you need to know about the anatomy of a staircase should you have any questions. We offer many of the parts needed for interior staircase building and repair, including square wood balusters, handrails, and finials. We believe quality matters more than quantity and use only the finest woods.
