A full kitchen renovation runs $25,000 or more and takes weeks. Replacing cabinet hardware costs $30–$80 and takes about 30 minutes — yet the visual impact is disproportionately large. Worn brass knobs from 2004 can make an otherwise clean kitchen look dated, and swapping them is one of those rare projects where the effort-to-payoff ratio genuinely favors the homeowner.
Measure Before You Buy — Hole Spacing Is Everything
The single most important number in this project is center-to-center spacing, sometimes called “bore” — the distance between the screw holes on a pull. Standard spacing on most American cabinets is 3 inches (76 mm) or 3.75 inches (96 mm), but older or custom cabinets can run anywhere from 2.5 to 5 inches.
Close the door or drawer and measure from the center of one existing hole to the center of the next. Write down every measurement — do not assume all your cabinets match, because builders occasionally mix sizes on uppers and lowers. If your current hardware uses a single-hole knob and you want to switch to a two-hole pull, you will need to drill new holes, which adds a step but is still manageable in one evening.
Choosing Between Knobs and Pulls
A common approach that designers tend to agree on: knobs on doors, pulls on drawers. Drawers benefit from a horizontal grip, especially heavy cutlery drawers, while knobs work naturally on swing-open doors. That said, pulls on both is perfectly clean if you prefer the look.
For finish, brushed nickel and matte black remain the two most versatile options — they pair with white, gray, and wood-tone cabinetry without clashing. Whatever you choose, buy one extra beyond what you need. Matching hardware later if one breaks can be surprisingly difficult once a style is discontinued.
The Swap: Step by Step
The actual replacement is one of the simplest home projects you will encounter:
- Remove old hardware. Back out the screws from inside the cabinet door or drawer front with a screwdriver. Set the old hardware aside in a bag in case you need it later.
- Clean the surface. There is almost always a grime ring where the old knob sat. A damp cloth with a drop of dish soap handles it in seconds.
- Test-fit the new piece. Thread the new screw through from the back, attach the knob or pull, and finger-tighten. Check alignment before committing.
- Tighten evenly. Snug the screw with a screwdriver — not a drill on high torque, which can crack a cabinet face. A quarter-turn past finger-tight is typically enough.
- Repeat. A typical kitchen with 20 cabinets and 10 drawers takes 25–35 minutes at a steady pace.
If you need to drill new holes for a different bore spacing, use a cabinet hardware jig (under $10) to keep your holes straight. If you have tackled other small projects like prepping for a weekend paint job, this will feel even more straightforward.
Common Mistakes That Slow You Down
The most frequent issue is screw length. Cabinet hardware screws are not universal — a 3/4-inch-thick door needs a different screw than a 1-inch overlay door. Most new hardware ships with standard 1-inch screws (#8-32 thread), but if yours poke through the front or fall short of the back, buy the right length separately. Hardware stores sell them individually; bring your old screw to match the thread.
Another common snag: overtightening pulls so they sit crooked. Always hold the pull straight with one hand while you tighten the first screw, then snug the second. Going screw-by-screw without holding the pull in position almost always results in a slight twist.
If you are planning a few small upgrades this season, the daily deals page is worth a quick check before you buy — hardware and tools turn up there more often than you would expect.
Making It Last
Quality hardware should last a decade or more, but kitchen cabinets open and close thousands of times a year. Once a year, spend five minutes snugging any knob or pull that wobbles. A loose knob gradually wallows out its hole — a much harder fix than a quarter-turn with a screwdriver. If one will not stay tight, a small drop of blue threadlocker on the screw threads solves it permanently.
Frequently Asked Questions
Can I replace cabinet hardware if I am renting?
Yes — this is one of the most renter-friendly upgrades. Save the original hardware and screws in a labeled bag so you can reinstall them before move-out. Most leases allow cosmetic swaps as long as you return things to their original condition.
How much does it cost to replace all the hardware in a kitchen?
A typical kitchen has 20–30 knobs and pulls. Budget options run $1.50–$3 per piece, mid-range $4–$8. For a full kitchen, expect $30 to $150 depending on style and finish.
Do I need to repaint cabinets after swapping hardware?
Not unless the new piece is smaller than the old one and exposes unfaded wood or paint. A dab of matching touch-up paint covers any shadow. In most cases, the new hardware covers the same footprint.
