When it comes to door knobs, there are two main categories: indoor and outdoor. Indoor door knobs are designed for doors inside the house, such as bedrooms, bathrooms, utility rooms, and closets. On the other hand, outdoor door knobs are made for exterior doors and are usually more durable and robust to handle the elements.
Within these two categories, there are several subtypes of door knobs, each serving a specific purpose. For instance, privacy knobs are commonly used in bedrooms and bathrooms to prevent accidental walk-ins, while passage knobs are typically used in closets or hallways where privacy is not a concern. Dummy knobs, also known as fake knobs, are purely decorative and often found on cabinets or appliances.
When choosing a door knob, it is important to consider factors such as security, privacy, ease of use, and aesthetics. Additionally, measurements like the bore hole size, backset, and door thickness should be taken into account to ensure the knob fits the door properly.

Privacy knobs are tailor-made for bedroom doors, with a lock on the knob itself
Privacy knobs are ideal for bedroom doors, providing peace of mind and security for the user. They are specifically designed to prevent accidental walk-ins, offering a basic level of privacy for the user.
Privacy knobs differ from keyed entry door knobs, which are designed to be used on exterior doors, such as front doors, patio doors, and garage doors. These exterior knobs require a key to lock and unlock and are made from more robust and durable materials to withstand the elements.
Privacy knobs, on the other hand, typically feature a lock on the knob itself, which can be activated by a simple twist or button mechanism. This lock provides a basic level of security, but it is not suitable for exterior doors as it can be easily bypassed.
When choosing a privacy knob for a bedroom door, it is important to consider the measurements of the door to ensure the correct size knob is purchased. The diameter of the borehole, the distance from the hole to the door's edge (known as the backset), and the thickness of the door are all important factors to consider.
Privacy knobs are available in various styles, colours, and finishes to suit any bedroom décor. Some popular brands offering privacy knobs include Kwikset, Schlage, and Probrico.
In summary, privacy knobs with locks are an excellent choice for bedroom doors, offering convenience, privacy, and security for the user.

Passage knobs are for rooms that don't need to be locked, like closets or hallways
Passage door knobs are used for rooms that don't require locking, such as closets or hallways. They are also referred to as unkeyed knobs. They are similar to dummy door knobs, which are one-sided and often used on shallow closets or the interior of French doors. Passage knobs are typically used for interior hallways, closets, and other rooms that don't require privacy locks.
Passage knobs are available in a variety of styles and finishes to match your room's decor. For example, you can find them in matte black, satin nickel, antique brass, or aged bronze.
When choosing a passage knob, it's important to consider the measurements of your door to ensure the proper fit. The standard backset, which is the distance from the edge of the door to the centre of the borehole, is typically 2 3/8 or 2 3/4 inches. The borehole diameter should match the new knob, and the thickness of the door should also be considered, with interior doors typically measuring around 1 3/8 inches and exterior doors measuring 1 3/4 inches.
Passage knobs are a convenient and practical choice for rooms that don't require locking, providing easy access while maintaining the style and functionality of a door knob.

Keyed entry knobs are used for exterior doors and require a key to open
Door knobs are available in various styles, sizes, and finishes. They are also designed for different purposes. When choosing a door knob, you need to consider what you need it for.
Keyed entry knobs are a type of door knob designed for exterior doors. They are locked and unlocked with a key on one side and sometimes on both sides. On the other side, they usually feature a twist mechanism for locking and unlocking. They are considered more secure than privacy knobs, which are typically used for interior doors.
Keyed entry knobs are ideal for exterior doors as they provide a higher level of security. They are made from more robust and durable materials to withstand the elements. Additionally, they require a physical key, limiting entry only to those with a copy of the corresponding key. This adds an extra layer of protection against intruders.
The lock and key mechanism of keyed entry knobs offers a traditional and reliable way to secure your home. These door knobs have stood the test of time and are less prone to technological issues associated with keyless entry systems, such as power loss or Bluetooth connectivity problems.
When installing keyed entry knobs, it is important to ensure that you have the correct measurements. The standard thickness for exterior doors is 1¾ inches. The backset, or the distance from the edge of the door to the centre of the knob, is typically 2⅜ or 2¾ inches. By taking the necessary measurements, you can ensure that your keyed entry knobs fit properly and function as intended.
