Different Types of Door Knobs and Which One Fits Your Needs Best

When setting up or renovating a space, door knobs may not be the first item on your checklist but they’re among the most used hardware in any home or office. Whether you’re stepping into a room, closing a cabinet, or adding a finishing touch to your décor, the type of knob you choose plays a part in everyday functionality and the overall ambience of a space.

From functionality to aesthetics, door knobs come in a variety of styles, each meant for specific kinds of doors and uses. In this blog, we break down the different types of door knobs, their materials, and how to choose the right one for your space.

What is a door knob?

A door knob is a round or oval-shaped handle used to open or close a door. It typically works by turning the knob to retract or release a latch mechanism inside the door, allowing it to swing open or shut. Door knobs are usually installed on interior or exterior doors and come in various styles and finishes to match different design preferences.

If you're wondering what is door knobs used for in different rooms, the answer depends on the door type and its function. A door knob is a device used to open or close a door. It typically consists of a round or oval handle, a spindle (which connects the two knobs on either side of the door), and a latch mechanism that keeps the door closed. Depending on its design, a knob may also include a locking system or be purely decorative.

Over time, door knobs have evolved from purely functional items to decorative elements that complement the overall look and feel of the room. Today, homeowners and designers alike consider both design and practicality while choosing the right door knob for each room.

Types of door knobs

There are several kinds of door knobs designed for different use cases. Here’s a closer look at the most common types:

a. Passage door knobs

Passage knobs are non-locking knobs typically used for interior doors that don’t require privacy such as hallways, closets, or pantry doors. They allow the door to latch but do not lock.

b. Privacy door knobs

These are often used in bedrooms and bathrooms. They come with a simple locking mechanism, usually operated with a push button or twist lock on one side, and an emergency release on the other.

c. Keyed door knobs

Keyed knobs are designed for doors where access needs to be controlled, such as main entrances or exterior doors. These usually feature a keyhole on one side and a turn button or twist lock on the other.

d. Cylindrical door knobs

Cylindrical door knobs are commonly used for both residential and commercial doors. They are easier to install than mortise knobs and are available in passage, privacy, and keyed versions. Cylindrical door knobs are appreciated for their straightforward design and reliable performance.

f. Mortise door knobs

These are typically heavier and more robust. Mortise knobs are installed with a rectangular pocket cut into the edge of the door. They’re often used in older homes or where a more traditional or substantial look is desired.

Door knob materials and finishes

Door knobs come in various materials and finishes, each offering its own combination of look, durability, and maintenance.

• Stainless steel door knobs: Known for their durability and simple appearance. Often used in kitchens, bathrooms, or minimalist modern designs.

• Brass: Available in both polished and antique finishes. Works well with traditional interiors.

• Matt Black: Popular in modern homes. Matt black knobs add contrast and style to lighter doors.

• Bronze: Offers a classic look and can develop a patina over time, which suits vintage-inspired spaces.

Choosing the right finish depends on the design tone of your home and the level of maintenance you're comfortable with.

Different rooms have different requirements, and so do their doors. Choosing the right kind helps improve the overall experience of your space.

Before making a purchase, consider the room type, door material, daily usage, and design theme. And when you're ready to browse, a range of options, spanning modern to traditional, are just a click away.
