To install cabinet hardware, gather a drill, tape measure, pencil, and a jig. Mark hole placements on each door and drawer, drill clean pilot holes, then fasten screws from the inside out. Tighten knobs or pulls by hand first, then snug them with a screwdriver. The whole job takes one afternoon.
Installing new cabinet hardware is one of the easiest ways to change the entire feel of a kitchen or bathroom. You don’t need to hire anyone. You don’t need a lot of tools. You just need a plan, a little patience, and this guide to walk you through it.
Whether you’re adding hardware to brand-new cabinets or swapping out old knobs for something fresh, the process is the same. Let’s get into it.
What Tools and Materials You’ll Need
Before you touch a single cabinet door, get everything together. Running back and forth to find a missing tool mid-project wastes time and breaks your focus.
You’ll need a power drill with a 3/16-inch (5mm) drill bit, a tape measure, a pencil, a level, and a screwdriver — either Phillips head or flat, depending on your hardware screws. A cabinet hardware jig is worth every dollar. It helps you get consistent placement across every door without measuring from scratch each time. You can buy one at any hardware store for under $20, or make a simple DIY version out of cardboard.
Keep a few extra screws on hand in case any get lost or stripped during the job. It’s a small thing that saves a big headache.
How To Choose the Right Hardware Size
Not all cabinet pulls are the same size, and buying the wrong ones means extra holes you’ll have to fill later. To find hardware that fits existing holes, measure the center-to-center distance — the gap between the middle of one screw hole to the middle of the other.
Standard pulls often have a 3-inch or 3-3/4-inch center-to-center spacing, but this varies. Always check the packaging before you buy. If you’re starting with cabinets that have no holes yet, you have more freedom — just pick the size that looks right for the door width and go from there.
For knobs, you only need one hole per door, so sizing is simpler. For pulls, you need two holes that line up perfectly. That’s where your measuring and jig do the heavy lifting.
How To Place Hardware on Cabinet Doors
Placement is where most people second-guess themselves. There’s no single universal rule, but there are standards that look great on most cabinets.
For wall cabinets, position hardware 2 to 3 inches from the bottom corner of the door. For base cabinets, place it 2 to 3 inches from the top corner. This creates a balanced, intentional look across the whole kitchen.
Measure up from the bottom edge of the upper cabinet door — or from the top edge of the lower cabinet door — and make a small pencil mark. Then measure in from the side of the door and mark that spot too. Where those two marks cross is exactly where your hardware goes.
Always use a level before you drill. A pull that’s even slightly crooked will catch your eye every single time you open the cabinet.
How To Mark and Drill the Holes
This is the step people fear most, but it’s actually straightforward when you go slowly and check twice before drilling.
Use a jig to make sure placement stays consistent across all doors. Drill pilot holes through the cabinet door at the marked locations. If you don’t have a jig, a sturdy piece of cardboard cut to the exact size of one door works just as well. Find the center by folding the cardboard in half both ways, mark it, then use the hardware’s spacing measurement to mark each hole.
Place a scrap piece of wood behind the cabinet door before you drill. This backing board supports the wood fibers and gives you a much cleaner exit hole on the inside of the door. Without it, the drill can tear or splinter the wood on the backside — which is a frustrating mistake to fix.
Start with a smaller drill bit first, then move up to the correct size. This prevents the wood from splintering around the edges of the hole. After drilling, run your finger around each hole. If you feel rough edges, a quick pass with fine-grit sandpaper smooths them out and lets the hardware sit flat against the surface.
Do one door first as a test. Before you commit to drilling every door, test fit one set of hardware and confirm all measurements are accurate. Make any adjustments before moving forward with the full installation.
How To Attach the Knobs and Pulls
With the holes drilled, the rest goes fast. Lay out all your knobs or pulls along with the screws before you begin attaching anything. Having everything organized in front of you keeps the process moving without stops.
Line up the pull or knob to the hole in the cabinet and insert the screw from the back — the inside of the cabinet door. Tighten with a screwdriver until the hardware is firm against the door.
For pulls, it’s easier to align the hardware from the front of the door first, then reach inside and thread the screws in from the back. A small dab of thread sealant or superglue on the screw before you tighten it keeps the knob from loosening over time or spinning when you grab it. This is especially useful on drawers that get pulled open dozens of times a day.
Don’t over-tighten. Pressing the hardware too hard against a painted surface can crack the finish or dent the wood underneath. Snug is enough.
How To Handle Drawers Differently
Drawers follow the same general process as cabinet doors, but the placement rule shifts. For drawer fronts, measure and mark the center point of the drawer — both horizontally and vertically — to find where the pull should sit.
Most pulls on drawers look best centered on the face of the drawer. Measure the total width and height of the drawer front, divide both numbers in half, and that’s your center point. From there, mark your screw holes based on the pull’s center-to-center spacing — half the spacing to the left of center, half to the right.
Use the same backing board trick here. Drawers tend to have thinner fronts than cabinet doors, so protecting the inside surface matters even more.
How To Fix Mistakes and Cover Old Holes
Mistakes happen, and they’re fixable. If you drill a hole in the wrong spot, don’t panic.
Fill the mistake with wood filler, let it dry completely, then sand gently in a circular motion until the surface is smooth and level. Wipe away dust with a damp cloth before painting or staining over the area. Match the cabinet’s finish as closely as possible — most hardware stores can color-match paint if you bring in a photo or a small chip.
If your new hardware doesn’t fully cover an old hole from previous hardware, add a backplate. Backplates sit between the hardware and the cabinet door, covering gaps and giving the whole installation a cleaner, more finished look.
How To Keep Hardware Looking Good Long-Term
Installing the hardware is step one. Keeping it in good shape is the other half of the job.
Adding a small amount of thread sealant to the screw before tightening creates a bond that holds everything firm over time — even with daily use. Check all hardware once a year and tighten any screws that have worked loose.
Clean hardware regularly with a soft cloth and mild soap. Harsh chemicals can strip finishes, especially on brass or bronze pieces. A gentle wipe-down every few weeks keeps pulls and knobs looking the way they did on installation day.
Final Checks Before You’re Done
Walk through the entire kitchen or bathroom once everything is installed. Open and close each door and drawer a few times. The hardware should feel solid, sit flush, and line up consistently across the row.
Make sure all doors hang straight and align correctly. If any door is off, adjust the hinges rather than the hardware itself. Cabinet hardware installation is one of those projects where the details are everything — and when it’s done right, the whole room looks like a different space.
You did this yourself. And it shows.
