What is Casing in Interior Design?

Casing is a popular interior design technique used to finish off the edges around door and window openings. It is a trim that frames the edge of the opening, providing an aesthetically pleasing look and protecting the walls from damage.

What is Casing made from?

Casing can be made from various materials such as:

  • wood,
  • plastic,
  • or vinyl and come in many different styles, shapes, and sizes so you can find one that best fits your home’s style.

While it doesn’t serve any structural purpose, it does contribute to making a room feel more finished and inviting. Often times casing also serves as an architectural detail which adds character to a room. Installing casing yourself is fairly straightforward with some basic tools so anyone can do it!

Casing is a great way to update the look of any room without major renovations. With so many options from traditional to modern, you can create a unique and stylish look for your home. So if you’re looking for an easy and affordable way to give your space an instant facelift, consider adding casing.

What is the difference between a frame and a casing?

  • While both framing and casing serve the same purpose of covering the edges around a door or window opening, there are some major differences between them.
  • Frames are typically larger and thicker than casings, so they often offer more protection against wear and tear.
  • They also have an extra decorative touch to them, such as moulding, that is absent from casings. In contrast, casing is thinner and more visually appealing than frames.
  • It’s a great way to add character to your home without being too overbearing.

What is the difference between casing and trim?

Casing and trim are often used interchangeably, but there is a subtle difference between the two. Casing typically refers to the material that covers the edges around door and window openings while trim can refer to any type of decorative element added to a room. Trim can include:

  • baseboards,
  • crown moulding,
  • chair rails,
  • etc., and can be made from almost any material such as wood, metal or plastic.

So while casing and trim may look similar in style, they serve different purposes in interior design.

What are the benefits of using Casing?

Casing has several advantages when it comes to interior design. It adds an extra layer of protection against scratches and bumps on walls caused by furniture and everyday wear and tear. It also serves as a finishing touch for any room, making it feel more finished and inviting. Casing is also relatively easy to install and can be done with basic tools so you can do it yourself if you’re feeling up to the task!

What is casing vs baseboard?

Casing is typically installed around doors and window openings while baseboards are used to cover the bottom edge of walls. Baseboards also come in many different shapes, styles, and sizes so you can customize them to fit your home’s style. They serve as a transition between flooring and wall surfaces, whereas casing is purely decorative. Casing adds character to any room while baseboards help protect walls from damage caused by furniture and everyday wear and tear.

What is a door casing?

A door casing is a trim or frame that surrounds the edges of a door opening.


Casing is a great way to finish off the edges around a door or window opening without having to undertake major renovations. With its wide range of styles, shapes, and sizes, there is something for everyone. Not only does casing add an extra layer of protection against wear and tear, but it helps to tie a room together and create a finished look.
