Though it’s one of the most used items in a home, door knobs are often overlooked when it comes to interior decor. Bedrooms, bathrooms, closets, and hallways are accessed by doors with knobs. While these fixtures often have a subtle visual statement, door knobs can still accentuate home decor and add style to entryways.
Door knobs are available in numerous designs, ranging from modern to vintage, in such finishes as brushed nickel, chrome, and brass. Door knobs also vary in function; a standard passage knob provides a means for opening a door, while privacy knobs feature simple locks suitable for bedrooms and bathrooms.

What to Consider When Choosing the Best Door Knobs
When shopping for door knobs, it’s essential to know the measurements that determine which knobs are compatible with your doors. Choosing a suitable knob type and an appropriate style and finish also are crucial parts of the decision-making process.
There are three main types of interior door knobs: privacy, dummy, and passage. Each type serves a different purpose and is more suitable for particular rooms.
- Privacy door knobs feature a twist or button lock on one side of the knob. The locking feature makes this type of knob suitable for bedrooms and bathroom doors. These locks offer minimal security and typically feature a small hole on the opposite end, allowing the user to unlock the door with a universal key.
- Dummy door knobs are one-sided knobs that don’t include any internal working parts. They essentially serve as a means for pushing or pulling open the door. Some dummy knobs come in pairs for use on double doors. They work well for small pantries, bedroom closets, or one side of a french door.
- Passage door knobs operate a latch assembly, but typically include no locking mechanism. They are good options for interior closets, hallways, and other rooms that don’t require privacy locks.
There are three important measurements to establish before selecting a new door knob: cross bore, backset, and door thickness.
- Cross bore refers to the large round hole where the door knob is mounted. A standard cross bore hole is 2⅛ inches in diameter. The cross bore hole must be smaller than the diameter of the door knob’s backplate to fit.
- The backset is the distance between the center of the cross bore to the edge of the door. There are two standard backset measurements: 2⅜ inches and 2¾ inches. The backset of the door knob must match the backset of the door, or it won’t fit.
- The thickness of interior residential doors can vary, which also impacts whether a door knob will fit. Older homes tend to have thinner doors of 1⅜ inches, while newer homes have thicker 1¾-inch-thick doors. Most knobs can work with a range of door thicknesses.
Like door handles, interior door knobs come in a variety of materials. Door knobs comprise a knob and a backplate, also called a rosette, which may be constructed of the same or different materials. Modern door knobs most commonly feature metal, though glass and ceramic options are also available.
Cut class and crystal door knobs provide unique decorative accents to entryways. These knobs were popular in the mid-19th to early 20th century, and many available today have a similar antique look. Faceted, octagonal, diamond, fluted, and bubbled are among various designs that can add a charming old-world aesthetic to your space.
Ceramic door knobs are often painted for decorative purposes. Most feature patterns and colors that add eye-catching visuals to doorways. Knobs containing ceramic are most often made of porcelain, which is denser and more durable than other types of ceramic.
Most door knobs with metal exteriors are made of brass, with more high-end options featuring chrome or stainless steel. Metal knobs are the most durable options and can vary in aesthetic from modern to vintage. The internal parts of high-quality door knobs consist of steel, which can withstand heavy use, treated with a nickel plating to resist corrosion.
The variety of door knobs available are intended to accentuate different home decor styles. Door knobs featuring clean lines and sleek finishes work well with minimalist and modern decor. These knobs can also work well for industrial-style homes, whereas metal knobs with an aged or distressed look complement vintage industrial decor.
Antique-looking metal accents and finishes can also pair well with rustic, farmhouse, and traditional decor. Historical homes and traditional interiors with Victorian-era decor can benefit from glass door knobs for a period aesthetic. For interiors such as bohemian, transitional, and eclectic, glass or colored knobs can add brightness and originality to the home.
Door knobs come in numerous colors and finishes to suit these different decor styles. Metal finishes include brass, pewter, chrome, black, bronze, copper, and polished nickel. Glass door knobs feature clear or colored designs, while ceramic options tend to feature one or more colors.
Installing a door knob is an easy DIY project that can usually be completed with a Phillips-head screwdriver. Most knobs include detailed installation instructions to walk users through the process. Only some door knobs come with the required hardware, so check product details to determine whether or not these parts are included.
Since they don’t have latch assemblies that hold the door to the door frame, dummy door knobs are naturally the easiest to install. Passageway and privacy door knobs are a little more complicated but are still very manageable, even for those who lack DIY experience.

FAQs About Your New Door Knobs
If you still have questions about the door knob style to install in your home or want to know more about door knob durability, read on for answers to some of the most commonly asked questions.
Q. What is the most popular color for door knobs?
Although color preferences vary, brushed nickel (also known as satin nickel) is the most popular finish for door knobs.
Q. Should all my door knobs match?
While all the hardware in a home does not need to match, matching all of the interior door knobs will help achieve a cohesive look. On the other hand, if the home features a style such as bohemian or eclectic, mismatched door knobs could accentuate the decor.
Q. Do knobs get broken often?
Door knobs can last a surprisingly long time when made from quality components. As with many mechanical items in the home, door knobs that feature locking mechanisms tend to wear out more quickly. Passage knobs, which have fewer moving parts, or dummy knobs, which have no internal moving parts, will last longer by comparison.
Q. Is there any maintenance needed for door knobs?
Wipe down a door knob with a mild soap and water solution or metal polish to prevent corrosion. For privacy knobs, spray lubricant such as WD-40 into the hole to lubricate the knob’s internal parts.
