Get the PDF GuideWhen I first tried to learn how to build cabinets I had a hard time finding all the information I needed. There was a little bit here, a little bit there, but nowhere did I find it all in one place. This post is my attempt to fix that. It’s a long read but if you’re serious about building your own cabinets it’s well worth the time. To build matching wall cabinets, see my post on How To Build Frameless Wall Cabinets.
Frameless cabinets are easy and affordable to build. They also provide more usable storage space than face frame cabinets. The design I find easiest to build and install is made of 3/4" plywood throughout — including a full back — with two four-inch stretchers at the top. Up to a 30" wide standard base cabinet carcass can be built out of a single sheet of 4’ x 8’ plywood.
The cabinet carcass is the main structural box — sides, bottom, back, stretchers. No doors, drawer fronts, or drawer boxes yet. The carcass can be configured for doors, drawers, open shelving, or any combination. We’re focusing on the standard configuration shown above. One book worth mentioning: Build Your Own Kitchen Cabinets by Danny Proulx. I haven’t read it myself but it comes up often in cabinet-building circles.
Standard Cabinet Dimensions
Before you start cutting anything, know what size you;re building. These are the standard dimensions for common applications.
| Application | Cabinet Height | Cabinet Depth | Counter Overhang |
|---|---|---|---|
| Kitchen Base | 34-1/2" (for 36" countertop) | 24" | 1" to 1-1/2" |
| Bathroom Vanity | 33" to 36" | 21" | 1" |
| Desk / Office | 28-1/2" (for 30" surface) | 20"–24" | 1"–2" |
| Toe Kick (standard) | 3-1/2" tall | 3" deep | N/A |

Cabinet Base Options
There are four ways to handle the base of a frameless cabinet. Your choice affects how you build the carcass, how you level during installation, and how you apply the finished toe kick.
Standard Base
The standard toe kick is 3-1/2 inches tall and 3 inches deep. This gives enough clearance to stand comfortably at the counter and matches the notch cut into a standard base cabinet carcass.
The sides and back extend to the floor. The front is notched 3" deep and 3-1/2" tall for the toe kick. A sub toe kick runs between the sides inside the notch for support and to give you a nailing surface for the finished kick board. Each cabinet needs to be shimmed individually during installation. This is what most semi-custom cabinets look like.
Standard Base - No Toe Kick
Same as above but without the notch. Use this for built-in desks, library cabinets, or anywhere a toe kick doesn’t make sense. A decorative board the same thickness as your doors covers the base of all cabinets after installation for a clean continuous look.
Adjustable Cabinet Legs
Blum leg levelers and Blum kick plate clips make installation easy on uneven floors. Height adjustments are simple during and after installation. The kick board clips onto the legs after everything is leveled. Good for damp environments (basement slab, garage) since the wood stays off the floor. Adds a small per-cabinet cost but the Blum hardware is worth it.
Separate Base Platform
A 2x4 frame with a 3/4" plywood top gives you a 4-1/4" platform (3-1/2" + 3/4"). Level the platform once, then set all your cabinets on it. No individual shimming per cabinet. The carcasses themselves are simpler to build — no toe kick notch to cut. This is my recommendation for most kitchen and bathroom builds.
Cabinet Back Options
Full 3/4" Back
The strongest option and the one used in this guide. Full 3/4" plywood throughout means one material, consistent joinery, and a cabinet that can handle heavy stone countertops and the appliances that go on top of them. Plan your cut sheet well and the cost difference over a nailer back is minimal.
Nailer Back
Two 3/4" nailer strips at the top and bottom of the back instead of a full panel. Saves material, works fine for shop or garage cabinets where you don’t need an enclosed back. You still have something solid to screw into the wall.
1/4" Back with Nailers
Nailer strips plus a 1/4" plywood panel stapled over them. Lighter and cheaper than a full back, gives you the enclosed look. Common in manufactured cabinets. The 1/4" panel can bow over time — not a structural issue but worth knowing.
Step 1: Calculate Your Dimensions
This is the part most people want to skip. Don’t. Getting the math right before you touch a saw means every cabinet in a run fits together without shimming and gap-filling. The formulas below work for any size cabinet, not just the 30" example we’re using here.
A note on edge banding: most iron-on edge banding is under 1/32" thick. I don’t factor it into my dimensions as long as it’s applied consistently before assembly. Wood moves. No cut is perfect. Consistency matters more than chasing fractions of a millimeter.
Cabinet Height
Determined by your application. Standard kitchen work surface height is 36". With a 1-1/2" thick countertop, your cabinet needs to be 34-1/2" tall.
Cabinet Depth
Standard kitchen depth is 24" including the door (23-1/4" carcass + 3/4" door). Bathroom vanity standard is 21". Check your appliance specs before committing — slide-in ranges and dishwashers sometimes have depth requirements that affect your design.
Cabinet Width
This is your call based on your layout. Our example uses 30" — the widest you can get from a single 4’ x 8’ sheet.
Component Dimensions
Our example: 30" W × 34-1/2" H × 24" D, 3/4" plywood throughout, standard base, full back. Grain direction follows the height on all pieces.
Cut List — 30" Standard Base Cabinet
This cut list is for the 30" W × 34-1/2" H × 24" D example. All pieces are 3/4" plywood. Use the formulas above to adjust for your dimensions.
| Part | Qty | Height | Width | Notes |
|---|---|---|---|---|
| Side | 2 | 34-1/2" | 23-1/4" | Edge band front edge before assembly |
| Bottom | 1 | 28-1/2" | 22-1/2" | Edge band front edge before assembly |
| Back | 1 | 28-1/2" | 33-3/4" | No edge banding needed |
| Shelf | 1 | 28-1/2" | 22" | Edge band front edge; pins installed after assembly |
| Stretcher | 3 | 4" | 28-1/2" | Edge band front edge on the 2 front stretchers |
| Sub Toe Kick | 1 | 3-1/2" | 28-1/2" | No edge banding needed |
| Total Parts | 9 | All from one 4’ × 8’ sheet of 3/4" plywood | ||
Step 2: Attach Side to Back
Apply edge banding to the front edge of both cabinet sides. Then drill pocket holes around the top and sides of the Cabinet Back and attach it to one side as shown. The bottom of the Back is flush with the bottom of the Side. Leave a 3/4" gap at the top — that’s where the rear stretcher will sit.
Step 3: Attach the Bottom
Apply edge banding to the front edge of the Bottom, then drill pocket screw holes and attach it to the Side and Back assembly. The bottom of the Bottom piece sits flush with the toe kick notch. Use your square at every corner — a box that’s out of square at this stage stays out of square.
Step 4: Attach the Other Side
Attach the second Side using the pocket holes already drilled in the Back and Bottom. No new drilling needed — that’s the beauty of drilling the pocket holes in the Back and Bottom pieces rather than the Sides.
Step 5: Attach the Stretchers
Apply edge banding to the front edge of the two front stretchers. Drill pocket holes and attach all three stretchers with the pocket holes facing up to minimize their visibility. The rear stretcher sits flush at the back, the two front stretchers go at the top front of the cabinet.
In this example the cabinet will have one full-width drawer across the top and two doors below. Spacing the second front stretcher depends on your desired drawer height. Standard top drawer height is 6". With overlay hardware, leave a 1/4" gap at the top to clear the countertop — so the second stretcher sits 6-1/4" down from the top of the cabinet.
Step 6: Install the Sub Toe Kick
The Sub Toe Kick supports the cabinet bottom, stiffens the whole carcass, and gives you a nailing surface for the finished kick board after installation. Drill pocket holes and attach it between the Sides at the front of the toe kick notch.
Step 7: Drill Shelf Pin Holes and Install Shelf
Use the Kreg Shelf Pin Jig to drill holes in the front and back of each Side. Position them 37mm from the front edge — use the short side of the jig without the fence. For the rear holes, flip the jig around. Leave at least 3"–4" clearance at top and bottom for door hinge hardware.
Edge band the front of the Shelf, insert shelf pins at the height you want, and drop the shelf in. The cabinet is done.
Frequently Asked Questions
What thickness plywood should I use for frameless base cabinets?
3/4" hardwood veneered plywood throughout. Some manufacturers build with 5/8" to cut costs, but if you’re building your own cabinets you might as well do it right. You’re already saving a lot over semi-custom, so the 3/4" is worth it. It also makes pocket hole joinery stronger and more predictable.
What is the standard height for a base cabinet?
The standard base cabinet height is 34-1/2" — that gives you a 36" finished work surface with a standard 1-1/2" thick countertop. Bathroom vanities run 33" to 36" depending on preference.
What is the standard depth for a base cabinet?
The standard depth for a kitchen base cabinet is 24" (23-1/4" carcass plus a 3/4" door). Bathroom vanities are typically 21". Check appliance specs before you commit — slide-in ranges and dishwashers sometimes have specific depth requirements.
Frameless vs face frame cabinets: which should I build?
Frameless for most DIY builds. More usable interior space, simpler construction (no face frame to build and attach), and a cleaner contemporary look. Face frame cabinets have a more traditional appearance if that’s what you’re going for, but frameless is faster and easier to build in my experience.
What base option do you recommend?
For most builds, the separate base platform. You level one simple 2x4 frame with a plywood top, then all your cabinets sit on it square and level without individual shimming. The platform costs a few 2x4s and a piece of plywood. On a large kitchen build the time savings over shimming six or eight individual cabinets is significant. It also simplifies the carcass — no toe kick notch to cut into the sides.
If the floor is concrete or damp, adjustable Blum leg levelers are worth the per-cabinet cost. The hardware is solid and keeps the wood off the floor.
Do frameless cabinets need a back?
For kitchen and bathroom cabinets I always use a full 3/4" back. The strength is worth it, especially under heavy stone countertops. For garage or shop cabinets that will be screwed to the wall anyway, nailer strips are fine. The 1/4" back with nailers is a reasonable middle ground when you want the enclosed look without the material cost.
How do I keep the cabinet square during assembly?
Clamp before you drive any screws. Use bar clamps or pipe clamps to hold pieces together, and corner clamps if you’re working alone. Once clamped, check each corner with a combination square, then measure diagonally corner to corner in both directions. Equal diagonals = square box. If they’re off, rack the assembly gently before the glue sets. Check at each step as you go rather than waiting until the end.
Can I build a base cabinet without a table saw?
Yes. A circular saw with a straight-edge guide gives you accurate rip cuts in plywood. It takes a bit more setup time per cut than a table saw, but the results are just as good if you’re careful with your layout.
How many cabinets can I get out of one sheet of plywood?
A 30" wide cabinet fits from a single 4’ x 8’ sheet — that’s what the cut plan diagram above shows. Narrower cabinets give you more flexibility. Always lay out your cut plan on paper before you touch the saw. Saving one sheet on a kitchen build is typically $60–$80, so the 20 minutes of planning pays off.
