An Overview of Interior Trim Elements

Trimmings might look like minor design elements, but they play a vital role in defining the appeal of your home’s interiors. Repainting or refinishing baseboard and casing combinations can improve the appearance of a space or room. On the other hand, replacing them can change the home’s overall look and feel. Here is a quick guide to interior trim elements:


The base is where the floor and wall meet. It also protects the wall finish from damage due to everyday foot traffic, furniture, and more. Bases usually have three parts: the shoe, baseboard, and cap.


Casings are the trims surrounding windows and doors. They are traditionally installed as separate pieces. The only difference between door and window casings is that the former has no bottom part. Baseboard and casing combinations can be found in matching styles because these elements need to complement each other.

Chair Rail

Chair rails are placed on the wall to protect it from furniture pieces. When they are one-third of the way up from the floor, the room will look taller. A more intimate feel is achieved when the rail is installed two-thirds of the way up from the floor. While it can be placed at any height, how it divides the wall is a significant design consideration.


Wainscots are panels positioned between the baseboard and the chair rail. Wainscoting lends the space or the room with an instant rustic look and feel.

Crown Molding

Crown moldings are placed at the top of the wall, concealing the part where the wall meets the ceiling. They soften the transition between the wall and ceiling. Crown moldings add an air of elegance to the area.

These trim elements play a significant role in the appearance of your home. Replacing them is an excellent way to breathe new life to an area or the entire house.
