Did You Know?
1. In the early 19th century, British architect Sir John Soane used an optical illusion called “forced perspective” to create the illusion of a larger doorway. By tapering door jambs towards the top, he effectively made smaller doors appear grander and more expansive when seen from a certain angle.
2. The concept of “secret doors” or hidden passages has a long history and was popularized during the Renaissance period. These hidden entrances allowed people to move between rooms discreetly and were commonly employed by nobility for both practical and security purposes.
3. The term “bespoke” used in relation to doors comes from the practice of tailoring doors to fit specific measurements. Originating in the United Kingdom, the term itself is derived from the word “bespeak,” meaning to speak for something or place an order in advance.
4. The world’s narrowest front door can be found in the Polish city of Szczecin. Measuring a mere 56 centimeters (22 inches) in width, it was designed in the 1970s to save space in small apartments. Despite its diminutive size, the door is fully functional and still in use today.
5. Japanese architect Shigeru Ban, known for his innovative and sustainable designs, once created a door that can be adjusted to fit various frame sizes. Made from curved paper tubes, the flexible door system allows for easy adaptation to different architectural constraints and offers a visually stunning entrance solution.
Building Out The Frame For A Smaller Door
When faced with the task of fitting a smaller door into a larger frame, there are several approaches you can take. One option is to build out the frame to accommodate the smaller door. This can be done by furring out the jamb, which is typically all that’s needed to make the opening smaller.
To build out the frame, you can use different materials such as one by four, one by six, or two by eight lumber. The choice of material will depend on the size and design of the frame. The lumber can be attached to the existing frame using wood screws that penetrate at least an inch into the framing. It’s important to ensure that the furring strips are securely fastened to provide a sturdy support for the smaller door.
It’s worth noting that when trimming around the casing, extra-wide trim may be required to compensate for the size difference between the door and frame. This helps to maintain a visually appealing appearance and ensure that the door looks proportionate within the larger frame.

Framing Options For Reducing The Size Of The Door Frame
In situations where the difference between the door and frame is less than an inch, it may not be necessary to build out the frame. Instead, you can align the door and frame by matching the dimensions. However, if the difference is greater, replacing the door casing with wider material may be necessary to ensure a proper fit.
For significant differences in size, additional steps may be required. This can include adding new drywall around the door frame to bridge the gap between the smaller door and larger frame. By doing so, the frame can be made smaller without compromising the integrity of the structure.
While the process of making a door frame smaller is not difficult, it’s important to note that professional help may be recommended if the door and frame are more than an inch apart. This ensures that the job is done accurately and efficiently, minimizing any potential issues that may arise during the installation process.
- Align the door and frame by matching the dimensions when the difference is less than an inch.
- Consider replacing the door casing with wider material if the difference is greater.
- Adding new drywall around the door frame can bridge the gap between a smaller door and larger frame.
- Professional help may be recommended for gaps larger than an inch.
Trimming Considerations For A Smaller Door Installation
When fitting a smaller door into a larger frame, several trimming considerations need to be taken into account. Here are some important points to keep in mind:
- Size difference: Assess the difference between the door and frame. If the difference is minimal, trimming the casing to match the new dimensions may suffice.
- Significant difference: If the difference is significant, it may be necessary to replace the old casing with broader trim or modify the wall to achieve a seamless and visually appealing result.
During this process, prioritizing safety is crucial. Here are some safety tips:
- Wear gloves and eye protection when removing an old door frame to prevent injuries.
- Use proper tools, such as a handsaw or circular saw, to ensure clean and accurate cuts when trimming the door frame.
Remember, achieving a precise fit and maintaining safety should be the primary objectives.
Measuring And Furring Out The Door Frame
Before fitting a smaller door into a larger frame, precise measurements are crucial. Measure the difference between the door and frame to determine the amount of adjustment required.
To make the door frame smaller, furring out one or both sides may be necessary. Furring strips made of 2×4-inch lumber are commonly used for this purpose. It’s essential to allow at least a 1/2-inch gap on each side of the door to ensure smooth operation. Additionally, leave a gap between the jamb and the top of the door and ensure a distance of 1/2 to 3/4-inch between the bottom of the door and the floor.
Furring strips should be attached to the existing framing using wood screws that are at least an inch long. To ensure a secure attachment, drill pilot holes with a 1/4-inch drill bit before driving the screws into the furring strips.
Steps To Make A Door Frame Smaller
Once the measurements have been taken and the frame has been furred out if necessary, there are several steps involved in making the door frame smaller.
- Remove the existing jamb and shims carefully. This can be done using a hammer and pry bar.
- Use a circular saw to fit the jamb pieces to the new opening. If narrowing the opening, cut the top jamb and rabbet the end of the jamb. If shortening the opening, cut the bottoms of the side jambs.
- Plumb the jamb pieces using new shims and a 4-foot level. This ensures that the door will hang correctly and function properly.
- Drive two-inch finish nails into the jamb and shims to secure the shims in place. It’s important to use a nail punch to sink the nails’ heads to avoid any interference with the door operation.
- Place the casing in place, cutting off an amount from the top casing equal to the narrowing of the frame. If shortening the opening, cut off the bottoms of the side casing.
- If necessary, replace the old casing with broader trim or modify the wall to ensure a visually pleasing result.
It’s crucial to work slowly and carefully throughout the process, checking measurements regularly to avoid any mistakes. If too much wood is removed from the door or if adjustments are not made accurately, it may cause irreversible damage to the frame or door.

Note: Keep in mind that making irreversible mistakes during the process can lead to damage of the frame or door.
Adjusting Hinges For A Better Fit
To achieve a better fit for a smaller door into a larger frame, adjusting the hinges can be beneficial. This is particularly helpful when the door seems to be the correct size but is sticking or not closing properly.
To adjust the hinges, follow these steps:
- Remove the door casing, top jamb, knob-side jamb, and hinge side jamb if necessary.
- Create furring strips using 2×4 lumber with a ½ inch gap on each side of the door, as well as at the top and bottom.
- Attach the furring strips to the framing using wood screws that penetrate at least one inch into the framing.
- Cut the jamb pieces to fit the new opening and attach them with shims.
- Ensure that the jambs are plumb using a level, and secure them with finish nails.
Once the hinges have been adjusted and the door is operating smoothly, you can replace the casing with wider trim if needed. This ensures a visually appealing and seamless transition between the door and frame.
It’s important to note that adjusting hinges is suitable for minor alignment issues with small changes. If the discrepancies are significant, it’s recommended to follow the steps outlined earlier to properly fit the door into the frame.
