Choosing the right door extensions for interior doors may seem like a small detail, but in reality, it is what makes the door look finished, stylish, and perfectly integrated into your wall. A beautiful door without properly matched extensions feels incomplete, as if the frame is missing its final touch. That’s why it is so important to know how to pick them wisely.

What are door extensions and why they matter
Door extensions, also known as jamb extensions, are additional panels that help adjust the frame of your door to the wall’s thickness. They not only cover construction gaps but also create a smooth transition between the wall and the door, adding a polished look. Without them, even the most expensive door may seem unfinished, as raw edges of the wall will be visible.
Think of extensions as the decorative frame of a painting. The painting itself is beautiful, but without the right frame, it loses depth and elegance. Extensions play the same role for your door—they complete the design and highlight its charm.
“Door extensions are not just accessories—they are the detail that transforms ordinary into perfect.”
They also help protect the edges of the wall from damage, scratches, or chipping, making your door last longer in both form and function.
How to measure correctly before buying extensions
The very first step in choosing extensions is correct measurement. Many mistakes happen when people rely on guesswork, and as a result, they either buy pieces that are too narrow or end up cutting materials in ways that ruin the design.
To measure properly:
- Measure the thickness of your wall from one side to the other
- Subtract the width of the door frame already installed
- The difference will show the width of the extension needed
If your walls are uneven, always measure in several places and take the largest value to avoid visible gaps. Professionals also recommend adding a few millimeters for safe fitting.
Numbered steps for accuracy:
- Take measurements on the top, middle, and bottom of the wall opening
- Record the largest number you find
- Choose the extension width that fully overlaps this size
This careful approach will ensure a seamless fit, so your door looks like it was designed with the wall from the very beginning.
Choosing the right material and finish
Extensions should match your interior doors not only in size but also in design. Luckily, manufacturers offer a wide variety of finishes that allow you to create harmony in any style.
Popular choices include:
- Veneered MDF extensions
- Solid wood for premium interiors
- Laminate options with durable surface
- Painted panels for a sleek and minimalistic look
When selecting the finish, think of the overall design of your space. A glossy surface adds a modern vibe, while natural wood tones create warmth and coziness. The right choice can make your door not just a passage but a design element that unites the entire room.
Installation tips and tricks
While extensions can often be installed as a DIY project, a professional finish requires precision. Correct alignment is key, as even the smallest misstep will create visible gaps or crooked lines. For those who value flawless aesthetics, professional installation is highly recommended.
Still, if you want to try it yourself, keep in mind:
- Dry-fit the extension before applying glue or fasteners
- Use clamps or spacers to hold them in place while securing
- Always start from the top and then move to the sides
- Check alignment with a level tool at each step
Patience here pays off, because the smoother the alignment, the more luxurious your final result will appear.
“The beauty of your door lies in details—and extensions are the detail that makes the difference.”
Additional design ideas with door extensions
Extensions are not limited to covering wall thickness. With a bit of creativity, they can serve as decorative elements that enhance the entire room. For example, you can choose contrasting colors to highlight the door frame or blend them seamlessly with the wall for a minimalist effect.
Creative options:
- White extensions for dark doors to create bold contrast
- Wooden tones to bring warmth into modern interiors
- Extensions with hidden lighting for a dramatic effect
- Wide extensions to imitate a classic portal look
By experimenting with finishes, you can turn a simple doorway into a design statement that speaks of your style.
