6 Door Knob Styles Worth Installing in Any Home
Schlage’s F51A Georgian knob is the top overall pick, built around heavier internal hardware and a Grade 2 cylinder rated for exterior use. Kwikset’s 200 Polo suits anyone who wants to rekey a lock without a locksmith. Amazon Basics covers low-traffic doors on a tighter budget.
Fit the Schlage F51A Georgian knob on a door that gets used daily. Heavier internals and a durable finish keep it working after a decade. Choose the Kwikset 200 Polo instead if rekeying without a locksmith matters more, and pick the Amazon Basics knob for a closet or spare room.
Buying a knob is trickier than it looks, since function has to match the door. Passage, privacy, dummy and keyed entry are not interchangeable, and swapping the wrong one means a return trip to the store. Backset and bore hole sizes also differ between older and newer doors. We compared function types, latch adjustability, cylinder ratings and what owners report about finish wear to rank the seven below.
The shortlist, ranked
Schlage F51A GEO Georgian Keyed Entry Knob
Schlage builds this knob around heavier internal hardware than most residential lines. Its ANSI Grade 2 cylinder sits well above entry-level security. The plain Georgian ball shape suits almost any door style, and owners report the finish outlasts cheaper knobs on exterior doors.
Pros
- Heavier internals than budget knobs
- Finish resists wear on exterior doors
- Adjustable latch fits both common backsets
Cons
- Rekeying needs a locksmith or a rekey kit
- Fewer decorative finish options than boutique brands
Kwikset 200 Polo Entry Knob with SmartKey Security
A SmartKey cylinder lets an owner rekey the lock with the existing key and a small tool, useful after moving house or losing a spare. The Polo shape is a simple ball design that suits most doors. Several finishes let it match existing hardware, and owners cite the rekey feature as the main reason to buy it.
Pros
- Rekey it yourself without a locksmith
- Easy to key several doors alike
- Straightforward installation with clear instructions
Cons
- SmartKey cylinders have known bypass criticisms
- Lighter feel in the hand than Schlage
Schlage F40 GEO Georgian Bed and Bath Privacy Knob
This privacy knob locks from the inside with a push button, then releases from outside with a small tool during a lockout emergency. Matching the F51A Georgian entry knob keeps finishes consistent through a house. Owners report the button mechanism keeps working long after cheaper privacy knobs start sticking.
Pros
- Reliable button mechanism over years of use
- Emergency release prevents lockouts
- Matches the wider Georgian range
Cons
- No key, so it offers no real security
- Push button can be pressed by children by accident
Kwikset 720J Juno Passage Knob
No locking mechanism sits inside this knob at all, which is exactly what closets, hallways and children’s rooms need. Fewer moving parts mean fewer things to fail, and it costs less than any locking option. Owners describe it as the sensible default for interior doors where a lock only causes problems.
Pros
- Simple mechanism with little to go wrong
- Cheapest way to fit a working interior door
- Available in matching finishes across a house
Cons
- No privacy function at all
- Lighter construction than entry rated knobs
Copper Creek BK2020PB Ball Door Knob
Copper Creek sells this plain ball knob in packs aimed at people fitting several doors at once rather than swapping a single knob. Commercial-grade internals give it a solid feel that outclasses most knobs at the same price. Landlords and renovators use it to standardise hardware across a whole property.
Pros
- Multipacks make whole-house consistency affordable
- Heavier feel than most knobs at this level
- Wide function range in one design
Cons
- Plain styling suits utility more than feature doors
- Finish range is limited
Nostalgic Warehouse Meadows Plate with Crystal Knob
A faceted crystal knob sits on a decorative backplate here, built for houses where a modern ball knob looks out of place. The plate covers a wider area of the door, hiding marks left by previous hardware. Buyers pick it for looks first and should expect a fussier fit than a plain modern knob.
Pros
- Suits period and character properties
- Backplate covers old hardware marks
- Available across matching functions
Cons
- Glass knobs feel cold and slippery in the hand
- Installation is fiddlier than a standard knob
Amazon Basics Door Knob with Lock
Low traffic interior doors are the target here, with a knob that latches and locks and nothing more. Installation follows the standard bore pattern, and the finish comes in plain satin nickel or bronze. Owners say it handles spare rooms and closets fine, while noting lighter internals than branded alternatives.
Pros
- Cheapest way to make a door usable
- Standard fitting with no surprises
- Fine for closets and spare rooms
Cons
- Lighter internals than branded knobs
- Not suitable for exterior or high traffic doors
Before you buy
What to look for in a door knob Four things decide whether a knob works on a given door: function, backset, bore hole size and finish durability. Function has to match the room, sizing has to match the door, and finish quality decides how the knob looks in five years. Get those four right and almost any brand performs reasonably well.
Which function fits which door Four functions cover nearly every door in a house. Keyed entry locks with a key from outside and belongs on exterior doors. Privacy locks with a button from inside and suits bedrooms and bathrooms. Passage only latches and works for hallways and closets. Dummy knobs do not turn at all and exist purely for doors held shut by a magnetic catch or a second active knob.
Measuring backset and bore hole before ordering Backset is the distance from the door edge to the centre of the knob hole, and it lands at either 2 3/8 or 2 3/4 inches on nearly all doors. Most modern knobs ship with an adjustable latch covering both. Bore holes usually measure 2 1/8 inches, though older doors sometimes vary. Measuring with a tape beats discovering a mismatch with a screwdriver in hand.
Finish durability and when a lever beats a knob Hands, keys and weather wear through plated coatings first at the highest contact points, which is where cheap knobs show their age. Unlacquered brass is meant to patina over time, while lacquered and PVD finishes resist wear but look damaged once scratched. Grip strength matters too: knobs need a twisting wrist motion that is harder for young children and older adults, so a lever suits accessibility needs better even though the mechanism and measurements underneath stay identical.

Frequently asked questions
What is the difference between passage and privacy door knobs?
Passage knobs latch the door closed with no lock at all, suiting hallways, closets and children’s rooms. Privacy knobs add a push button lock inside plus an emergency release outside, which bedrooms and bathrooms need. Installation is identical, so only the internal mechanism differs.
Can I rekey a door knob myself?
With a Kwikset SmartKey cylinder, yes, using the current key and the supplied tool in about a minute. Standard cylinders including Schlage need either a rekey kit and some patience or a locksmith visit. Choosing a rekeyable line from the start saves trouble when several doors need to share one key.
How do I know which backset my door has?
Measure from the door edge to the centre of the large knob hole. Expect a result close to either 2 3/8 or 2 3/4 inches. Most knobs sold today ship with an adjustable latch covering both, so this only becomes critical on older or non standard doors.
Are Grade 1, 2 and 3 security ratings worth checking?
Yes, for exterior doors. ANSI grades reflect cycle testing and force resistance, with Grade 1 built for commercial duty and Grade 3 covering basic residential use. Grade 2 is the sensible target for a house entry door. Interior passage doors barely need a grade at all, since nothing is trying to force them.
Will a new knob cover the marks left by the old one?
Sometimes. Rosette diameters vary between brands, so a smaller rosette can leave a visible ring of unworn finish around it. Knobs mounted on long backplates, like the Nostalgic Warehouse design, cover the largest area. Measuring the old rosette before buying avoids an unwanted repainting job.
Can the same knob work on interior and exterior doors?
The style can, but the function should not. Exterior doors need keyed entry hardware with a proper cylinder and a weather resistant finish. Fitting an interior privacy or passage knob outside is both insecure and hard on the finish. Most ranges sell matching styles across every function, so the look stays consistent.
Do door knobs come with a strike plate and screws?
Almost always. Sets normally include the latch, strike plate, mounting screws and any required spindle. A longer screw for reinforcing the strike into the stud is often missing, and adding one is a cheap upgrade worth making on exterior doors.
Should I choose a knob or a lever for my door?
Pick a lever if anyone in the household has limited grip strength, since levers open with a push rather than a twist. Knobs are harder for small children to open, which some parents actually prefer. Bore hole, backset and installation stay the same for both, so switching later is straightforward.
What is the difference between passage and dummy knobs?
Passage knobs have a working latch that pulls the door shut. Dummy knobs do not turn or latch at all, and exist only as a handle on a fixed door leaf, usually paired with a magnetic catch. Both install the same way but serve completely different jobs.
The verdict
Fit the Schlage F51A Georgian knob on doors that matter, since its heavier internals and better finish are exactly what shows after years of daily use. Choose the Kwikset 200 Polo with SmartKey instead if rekeying yourself is worth more than that extra solidity, and reserve the Kwikset 720J Juno passage knob for interior doors where a lock would only get in the way.
