When it comes to bi-fold doors, door knobs may not be the first thing you think of, but they play a crucial role in both the functionality and aesthetics of your door. Installing the right bi-folding door knob ensures smooth operation, enhances the look of your space, and adds to the durability of the door mechanism.
Whether you’re installing bi-folding door knobs for a new door or replacing old ones, there are a few things you need to consider before diving into the project.Â
In this article, we’ll walk you through 5 essential things you need to know before installing bi-folding door knobs.
Understanding the Mechanism of Bi-Folding Doors
Before you pick a bi-folding door knob, it’s essential to understand how bi-fold doors work. Unlike traditional doors that swing open, bi-fold doors are made up of two or more panels that fold inward, often in a zigzag or concertina style. Because of this folding mechanism, bi-folding doors require specialized knobs and handles. If you use a regular door knob, it may obstruct the folding panels or make it difficult to operate the door smoothly. Bi-folding door knobs are designed to be compact, ergonomic, and suitable for the folding mechanism.

Choosing the Right Material for Durability and Style
When selecting bi-folding door knobs, material matters just as much as style. The material you choose should be both durable and aesthetically pleasing, matching the overall décor of your room. Some popular materials include:
Brass
Offers a classic, timeless look and is highly durable. It’s often used in traditional or vintage-style homes.
Stainless Steel
Known for its sleek, modern look, stainless steel is perfect for contemporary homes. It's also resistant to corrosion and easy to maintain.
Chrome
A shiny, reflective finish that's ideal for a more polished look, often used in high-end design.
Wood
Wooden knobs add a rustic or organic touch and are great for cottage-style or farmhouse aesthetics.
Tip: Consider the environment in which the door knob will be used. For exterior bi-fold doors, stainless steel or brass is a better choice due to their weather resistance.

The Size of the Bi-Folding Door Knob Matters
Not all bi-folding door knobs are created equal in size. Since bi-fold doors are often narrower than traditional doors, the size of the knob can impact both its usability and appearance. The ideal bi-folding door knob should be easy to grip but not too bulky, as it could interfere with the folding mechanism.
Tip: Choose a knob that complements the scale of the door. A large knob may look out of place on a small door, while a tiny knob could be harder to use.

Handle vs. Knob: What’s Best for Your Bi-Folding Door?
While door knobs are a classic choice, bi-folding doors can also be fitted with handles. Handles can provide a more ergonomic grip, especially on larger bi-fold doors or doors that are opened frequently.
Advantages of Handles
- Easier to grip for people with limited hand strength.
-
Provides better control when opening and closing large panels.
-
Can add a more modern or minimalist aesthetic.
Advantages of Knobs
-
Typically more compact, making them a better fit for small bi-fold doors.
-
Classic design that complements traditional or rustic décor.
-
Easier to install due to smaller size.
Tip: If you're unsure, consider the frequency of door use and the aesthetic you want to achieve. Handles are better for frequent use, while knobs are ideal for less frequently accessed doors.

Installing the Bi-Folding Door Knob: Step-by-Step
Installing a bi-folding door knob might seem like a simple task, but it requires precision to ensure the knob works smoothly with the folding mechanism. Here’s a step-by-step guide to help you install the knob correctly:
Step 1: Measure the Placement
Before drilling any holes, measure where you want the knob to be positioned. Typically, the knob should be placed around 36 to 38 inches from the ground, depending on the height of the door and your preferences.
Step 2: Mark the Spot
Use a pencil to mark the spot where the knob will be installed. Double-check the alignment and ensure the mark is centered.
Step 3: Drill the Hole
Using an appropriate drill bit for your knob size, carefully drill the hole where you marked the spot. Ensure the hole is the correct diameter for the knob’s spindle.
Step 4: Attach the Knob
Insert the spindle through the drilled hole and attach the knob according to the manufacturer’s instructions. For bi-folding door knobs, you may need to ensure the knob is aligned with the folding mechanism, ensuring it won’t obstruct the door's function.
Step 5: Test the Door
Once the knob is securely installed, test the door to ensure it opens and closes smoothly. Make any adjustments if necessary.
Tip: If you’re unsure about installing the knob yourself, it’s always a good idea to consult a professional installer. Incorrect installation could affect the door’s operation.
Conclusion
Choosing and installing the right bi-folding door knob can make a huge difference in both the function and style of your doors. Whether you’re upgrading your door hardware or installing a brand-new bi-fold door, understanding the mechanism, selecting the right material, and considering size and style are all essential steps to ensure a successful installation.
By keeping these 5 essential things in mind, you can ensure that your bi-folding door knobs not only look great but also perform reliably for years to come.
