Yes, you can absolutely set kitchen cabinets yourself! Many homeowners successfully complete the DIY kitchen cabinet hanging process by following a clear, step-by-step plan. This guide breaks down everything you need to know to install kitchen cabinets like a pro, ensuring they are level, sturdy, and look great.
Preparing for Cabinet Installation: The Groundwork
Before you even think about mounting kitchen cabinets, proper preparation is key. Rushing this stage leads to crooked cabinets later. Think of this as laying a solid foundation for your kitchen remodel.
Measuring and Layout Planning
Accurate measurements save headaches later. Measure your space carefully.
- Wall Space: Measure the length of every wall where cabinets will go.
- Height: Measure from the floor to the ceiling. Note any obstructions like vents or windows.
- Location of Utilities: Mark where pipes, wires, or gas lines run. You must avoid drilling into these when securing kitchen cabinets.
- Cabinet Placement: Decide the exact spot for each base and wall cabinet. Plan the sequence. Usually, you start with the corner base cabinet.
Creating the Layout Guide: The Cleat System
The most crucial part of hanging kitchen cabinets is establishing a perfect reference line. Professionals often use a ledger board, or a cabinet cleat, screwed into the wall studs.
Steps to Create the Reference Line:
- Determine Base Cabinet Height: Standard countertop height is 36 inches from the finished floor. Your base cabinets sit under this. Subtract the cabinet height (usually 34.5 inches) from 36 inches. This gap (1.5 inches) is for your toe kick and floor leveling adjustments.
- Mark the Top Line: Measure up from the floor to where the top of your base cabinets will sit. Mark this line clearly on the wall using a level. This ensures all base cabinets start at the same height.
- Install the Ledger Board: Cut a straight piece of 1×4 lumber slightly shorter than the total run of base cabinets. Use a level to ensure this board is perfectly flat against the wall, lined up with your top line.
- Secure the Ledger Board: Drive long, sturdy screws (at least 3 inches) through the board and into every wall stud you locate. Use a stud finder to locate these reliably. This ledger board will temporarily support the weight of the base cabinets while you are attaching kitchen cabinets.
Installing Base Cabinets: Building the Foundation
Base cabinets go in first. They are heavy, and getting them right sets the stage for the wall units.
Assembling the Cabinets
If you bought pre-assembled cabinets, skip this. If they came flat-packed (Ready-to-Assemble or RTA), follow the manufacturer’s instructions exactly. Use wood glue on all joints for extra strength before using the supplied fasteners.
Positioning Kitchen Cabinets
Begin with the most important piece—usually the corner cabinet or the cabinet that butts up against an appliance like a stove or dishwasher.
- Lift and Rest: Lift the first cabinet onto the ledger board. Let the bottom rest on the board.
- Check Level and Plumb: This is where leveling kitchen cabinets happens. Use a long level on the top front edge (for level) and the side edges (for plumb—vertical straightness).
- Adjustments: Most base cabinets have built-in adjustable feet or you can use small wood shims between the cabinet bottom and the ledger board to achieve a perfect level. Take your time here. If the first cabinet is off, everything else will be off.
Securing Kitchen Cabinets to the Wall and Floor
Once the first cabinet is perfectly positioned, it’s time to secure the cabinets.
- Attaching to the Ledger Board: Drill pilot holes through the cabinet frame into the ledger board. Use screws appropriate for the cabinet material. Do not overtighten, or you might strip the wood.
- Leveling Cabinets to Each Other: If you have multiple base units side-by-side, you must connect them firmly before anchoring them completely to the wall. Clamp the adjoining cabinet faces together. Drill pilot holes through the adjoining cabinet faces, about 2 inches from the top and bottom. Drive cabinet screws into these holes to join them tightly. This prevents gaps between boxes.
- Final Wall Attachment: Once the run of base cabinets is connected and level, drive screws through the back mounting rails of the cabinets directly into the wall studs. Use cabinet mounting hardware designed for this purpose, especially if the cabinets are heavy or you anticipate placing very heavy items inside.

Installing Wall Cabinets: The Ascent
Mounting kitchen cabinets on the wall requires more careful planning because gravity is working against you. You cannot rely on a ledger board underneath for support during the process.
Establishing the Wall Cabinet Height Line
Wall cabinets usually sit 18 inches above the countertop. If you calculated your base cabinet top at 34.5 inches, add the 1.5-inch countertop, then add 18 inches for the wall cabinet bottom.
- Calculation Example: 34.5″ (Base Top) + 1.5″ (Countertop) + 18″ (Gap) = 54 inches.
- Mark this final hanging height line around the perimeter of the kitchen. This line dictates where the mounting kitchen cabinets will start.
Creating the Wall Support System
For hanging kitchen cabinets, you need a robust support system because you will be working overhead.
- Install a New Cleat: Install a sturdy ledger board (cleat) directly onto the wall studs, perfectly aligned with your marked hanging height line. This cleat supports the bottom of the wall cabinets during installation.
- Support Over Appliance Areas: If you have a gap above a stove or refrigerator, you cannot run the cleat continuously. You must install strong vertical supports (like vertical 2x4s cut to size) between the base cabinet top and the wall cabinet height to offer solid anchoring points between ledger sections.
The Hanging Process
It is highly recommended to have two people for hanging kitchen cabinets, especially the larger ones.
- Lift and Align: Lift the first wall cabinet. Rest the back bottom edge of the cabinet onto the ledger board cleat.
- Rough Positioning: Temporarily secure the cabinet using a couple of long, heavy-duty screws driven through the back mounting rail into the wall studs. Do not tighten fully yet.
- Leveling and Plumb Check: Check the cabinet for level (side-to-side) and plumb (front-to-back). Adjust using shims behind the cabinet back if needed.
- Securing Cabinets to the Wall: Once perfectly positioned, drive screws through the cabinet back rail into every accessible stud. For maximum stability, use screws long enough to penetrate the cabinet back, the drywall, and sink at least 1.5 inches into the stud wood. This step is crucial for securing cabinets safely.
Joining Wall Cabinets Together
Just like the base units, wall cabinets must be joined tightly to maintain consistent alignment.
- Clamp Together: Place the second cabinet next to the first. Clamp them tightly together, making sure the faces are flush.
- Drill and Fasten: Drill pilot holes through the cabinet sides (face frame or cabinet body, depending on style) near the top and bottom. Drive cabinet screws in to connect the two boxes firmly.
- Continue: Repeat this process across the entire run of wall cabinets. Once they are all joined and anchored to the wall, remove the temporary ledger board support, unless the design requires it to remain for trim installation.
Tip for Heavy Cabinets: If you have very deep or heavy upper cabinets, consider using temporary cabinet jacks or “pony braces” to hold the cabinet steady overhead while you drill and fasten.
Fine-Tuning and Finishing Touches
Once all the boxes are mounted, the real fine-tuning begins to achieve a professional look. This section focuses on achieving perfect alignment.
Adjusting Doors and Drawer Fronts
Modern cabinets, especially those with European hinges, offer significant adjustment capabilities. This is often the most frustrating part of the kitchen cabinet installation guide.
Door Adjustment Screws: Hinges typically have three main adjustment screws:
- Depth Adjustment (In/Out): Moves the door closer or further from the cabinet face.
- Side Adjustment (Left/Right): Moves the door horizontally to align the gap between doors.
- Height Adjustment (Up/Down): Often requires a specialized tool or moving the hinge base plate.
Use these adjustments systematically: first, ensure all doors are flush (depth). Second, line up the gaps between doors (side). Finally, adjust the height if necessary.
Installing Shelves and Hardware
With the boxes secure, you can install shelf pins and place the shelves. For drawer slides, ensure they are mounted exactly to the manufacturer’s specifications; slight variations can cause drawers to bind.
Attaching Toe Kicks and Light Railing
Toe kicks (the recessed area at the bottom) cover the temporary ledger board and cover uneven flooring.
- Toe kicks are usually fastened with clips or small screws driven up from the inside bottom of the cabinet.
- Light railing goes under the upper cabinets to hide under-cabinet lighting wires.
Specific Scenarios in Cabinet Mounting
Not all installations are straightforward. Here is how to handle common layout challenges when mounting kitchen cabinets.
Installing Corner Cabinets
Corner cabinets require precise angular measurements.
- L-Shape Base Corners: Install the first cabinet as normal, ensuring it is perfectly level. When positioning kitchen cabinets for the second corner unit, it must align perfectly with the first one. Use a large square to ensure the cabinet run forms a true 90-degree angle. Clamp them tightly before screwing them together through the side panels.
- Blind Corner Wall Cabinets: These cabinets have an access door on one side only. Ensure the face frames are perfectly flush with the adjacent cabinet faces before securing cabinets.
Handling Out-of-Plumb Walls
If your wall isn’t perfectly straight (common in older homes), you can’t rely on the wall to keep the cabinet plumb.
- Identify the Deepest Point: Use your level to find the point where the wall bows inward or outward the most.
- Shim Behind the Cabinet: Place shims between the back of the cabinet and the wall at the shallowest points. This pushes the cabinet away from the wall slightly so that the outer face of the cabinet appears perfectly plumb when checked with your level.
- Anchor Securely: When shimming, you must use longer screws or secure the cabinet to the ledger board very strongly, as the direct wall contact is reduced.
Cabinet Spacing Over Appliances
When attaching kitchen cabinets around an oven or refrigerator, maintain the required clearance specified by the appliance manufacturer. Sometimes, you must build custom filler strips or short vertical support boxes to bridge the gap between the ledger board sections and provide a solid anchor point for the upper cabinet.
Comprehending Cabinet Mounting Hardware
Choosing the right cabinet mounting hardware ensures longevity. Never rely solely on flimsy nails or short screws.
Key Hardware Types:
- Cabinet Screws: Heavy-duty construction screws (3-inch minimum) for anchoring into studs.
- Cabinet Joining Screws: Shorter, often specialized screws designed to pull two cabinet faces tightly together without piercing the other side.
- Hinges and Slides: These are usually supplied by the cabinet maker but confirm they are heavy-duty, especially for large pantry units or drawers intended for heavy pots.
- Cabinet Cleats/Ledger Boards: While not strictly “hardware,” the 1×4 lumber used for support is vital hardware for the installation process.
Frequently Asked Questions (FAQ)
Q: What is the standard gap between base and wall cabinets?
A: The standard gap between the top of the base cabinet (before the countertop) and the bottom of the wall cabinet is 18 inches. This allows enough space for small appliances and comfortable working room.
Q: Can I use construction adhesive instead of screws for mounting kitchen cabinets?
A: No. While adhesive can supplement screws, you must use screws to secure cabinets to the wall studs. Adhesives fail under the sustained weight and shifting pressures associated with daily kitchen use.
Q: How do I ensure my cabinet faces are perfectly aligned when installing a run of cabinets?
A: Use strong clamps to pull the faces of adjoining cabinets tightly together before driving the joining screws through the sides. Then, use a long level across the top face of the cabinets to check for any slight dips or rises between boxes.
Q: What if I cannot find a stud where I need to anchor a cabinet?
A: If you cannot hit a stud directly behind where you need to anchor, use heavy-duty toggle bolts or molly bolts rated for significantly more weight than the cabinet is expected to hold. However, it is always preferable to shift the cabinet slightly to hit a stud or install blocking (a wood brace) between existing studs for solid anchorage. This is essential for safe securing kitchen cabinets.
