Walk into a Home Depot hardware aisle and you will see roughly 200 SKUs spread across knobs, levers, and deadbolts. The different types of door handles are not interchangeable; pick wrong and a contractor charges you $80 to redrill a 1-inch latch hole into the 2-1/8 inch bore that newer hardware needs. Function (passage, privacy, dummy, entry) matters more than finish, but most homeowners shop the other way around.

Function Categories You Need to Match
- Passage: turns freely on both sides, no lock. Hallways, closets, laundry rooms.
- Privacy: push-button or thumbturn lock with emergency unlock. Bedrooms and bathrooms.
- Dummy: non-functioning, no latch. Surface-mounted on closet doors and double-door inactive sides.
- Entry/keyed: key on the exterior, thumbturn or button inside. Front, back, and garage interior doors.
- Deadbolt: separate lock above the handle for added security. Always paired with an entry handle on exterior doors.
Buy the wrong function and the door either will not lock when you need it or will lock you out. Every box at Home Depot, Lowe’s, or Build.com clearly labels the function, so check before checkout.
Knobs vs Levers: Which Belongs Where
Knobs cost less ($15 to $40 for a basic Kwikset Tylo) and resist accidental opening from cats, kids, and grocery bags. Levers ($25 to $60 for a Schlage Accent) are required by ADA and easier for arthritic hands or anyone holding a laundry basket. Most modern builds use levers throughout the interior because they read as more contemporary, but knobs still dominate in traditional homes. If you have pets that paw at doors, knobs are the smarter choice in bedrooms and bathrooms.
Backset and Bore Hole Sizing
Two measurements determine whether a handle fits your door. The bore hole (face of the door) is almost always 2-1/8 inches in modern construction. The backset (distance from edge of door to center of bore) is usually 2-3/8 inches in interior doors and 2-3/4 inches in exterior doors. Most quality handles ship with adjustable latches that handle both. Older homes built before 1960 sometimes have 1-3/4 inch bore holes, requiring vintage-style hardware from Rejuvenation or House of Antique Hardware.
Common Finish Options Ranked
- Satin nickel: the safest pick, hides fingerprints, works with almost any decor. Around $30 per knob.
- Matte black: trending hard since 2018, dramatic on white doors, scratches show easily. $35 to $80.
- Polished chrome: classic in bathrooms and kitchens, water spots constantly. $25 to $50.
- Oil-rubbed bronze: warm traditional look but the finish wears at the touch points within 5 to 10 years.
- Polished brass: back in fashion after a 30-year exile, especially the unlacquered live-finish version from Emtek and Baldwin.
- Antique brass: warm gold tone with a subtle patina, popular in transitional and traditional homes.
Smart Locks and Electronic Handles
Smart deadbolts have replaced traditional keys in millions of US homes. The August Wi-Fi Smart Lock ($230) retrofits over your existing deadbolt and keeps the original key working. Schlage Encode Plus ($300) is a full replacement with built-in Wi-Fi and Apple Home Key support. Yale Assure Lock 2 with Touchscreen ($260) integrates with Z-Wave and Matter. Battery life ranges from 6 to 12 months; pick a lock that emails or pings the app when batteries are at 20 percent so you do not get locked out at midnight.
Door Handle Sets vs Single Pieces
Front door handlesets combine a gripping handle, latch, and matching deadbolt in a single coordinated kit. Expect $200 to $500 for quality from Schlage F-Series, Baldwin Reserve, or Emtek Brass. Buying the deadbolt and handle separately can save $40 but creates a finish-matching headache because color batches drift between SKUs. For interior doors, single-pack knobs or levers are fine since they get less visual attention.
Specialty Handles for Sliding and Pocket Doors
Pocket door pulls (Emtek 2102, around $50) sit flush in the door so the door slides past the jamb cleanly. Mortise locks add a privacy lock to a pocket door and need a deeper edge mortise; the Schlage 990S costs about $100. Sliding barn door hardware uses a pull on each face of the door rather than a turning handle; expect $20 to $80 per pull. French door dummy levers come in pairs for the inactive door panel and need to match the active door’s handle exactly.
How Long Each Type Lasts
Quality solid brass handles from Baldwin or Emtek last 30 to 50 years. Mid-grade Schlage and Kwikset run 10 to 20 years before the springs lose tension. Builder-grade hardware from box-store house brands often fails inside 5 years, especially on heavy-use doors like garage entries. Smart locks have a different failure mode; the mechanical parts last but firmware support and app compatibility tends to drop after 7 to 10 years as manufacturers move on to new product lines.
Installation Tips Worth Knowing
Use a self-centering Vix bit (#7, around $12) when drilling pilot holes for new strike plates so the screws never wander. For smart deadbolts, upgrade the included 1-inch screws to 3-inch construction screws so the strike plate anchors into the wall stud, not just the jamb; this single change defeats most kick-in attempts. Shim the latch with a thin metal washer if the door rattles when closed. And always test the lock with the door open before you ever close it on the new hardware. Putting in the right type of door handle, in the right finish, with proper installation makes the difference between hardware you replace in three years and hardware you forget about for two decades.
