Corner Kitchen Cabinet Dimensions: Standard Size Chart (Inches + cm)
Exact standard sizes for every corner cabinet — base, wall, blind, Lazy Susan, sink and pantry — with a full chart in inches, centimeters and millimeters, plus how to measure your corner correctly.
Order cabinets before you know your real corner dimensions and you’ll end up with a unit that won’t fit — or a dead zone of wasted space. This guide gives you the standard specs for every corner cabinet type in inches and metric, plus how to measure your own corner so it fits the first time.

Sizes are consistent across major lines (IKEA, Home Depot, Lowe’s, KraftMaid); semi-custom and custom units vary. Upper corners also come in 18″ and 24″ widths. Conversions rounded (1″ = 2.54 cm = 25.4 mm; 36″ = 914 mm).
The Corner Cabinet Types, Explained
Which unit suits your layout — and the standard size to look for.
Lazy Susan Corner
Bi-fold doors and rotating shelves make the full corner reachable. The most accessible option for a base corner.
Blind Corner
One door face with deep hidden storage behind the adjacent run. Best for larger kitchens; pair with a pull-out to reach the back.
Diagonal Corner
Sits symmetrically in the corner with an angled front. A tidy look for kitchens where the corner is on show.
Corner Sink Base
Fits the sink and plumbing into the corner and opens up counter space on both sides. Allow 2–3″ extra for fixtures.
Upper / Wall Corner
Uses tricky wall corners for everyday storage. Leave 1–1.5″ of dead-corner clearance for the doors to swing.
Corner Pantry
Full-height corner storage, walk-in or angled. The biggest-capacity way to use a corner.
Standard sizes vs. custom units
Stock (standard)
Budget-friendly and easy to find — Home Depot, Lowe’s, IKEA, Amazon. Fits most L-shaped and U-shaped kitchens. Trade-off: the occasional gap or awkward angle.
Custom / semi-custom
Built to your exact corner — no dead space, with options like angled pull-outs. Trade-off: higher cost in materials and labor.
Bottom line: standard layout on a budget → go stock. Unusual angles or maximum storage → custom is worth it.
How to Measure for a Corner Cabinet
Five steps to get a fit that works the first time.
- Measure each wall length. Run a tape from the inside corner along each wall to where the cabinet will end. Note both measurements — corner runs are rarely equal.
- Check the face-frame distance. Measure from the corner to the cabinet’s face frame to see how much of each wall the unit will occupy.
- Account for countertop overhang and appliances. Allow the standard 1–1.5″ (2.5–4 cm) counter overhang, and confirm clearance for a nearby dishwasher, oven or fridge door.
- Include the corner angle. For a diagonal or angled unit, measure the front width and depth — typically 36″ across the face — and confirm against the manufacturer’s spec.
- Check squareness and plan the layout. Corners are often out of square, so measure the diagonals. Always place the corner unit first, then build the run outward from it.
A laser distance measure nails wall lengths and diagonals in seconds — far more reliable than a tape in a tight corner.
RockSeed Laser Measure on AmazonSpace & Clearance You Need
A standard 36″ blind corner base takes about 42–45″ (107–114 cm) of wall space once you allow for the door and pull-out. A 42″ blind corner needs roughly 45″ (114 cm).
Leave at least 2–3″ (5–7.5 cm) beside a corner cabinet door so it can swing without hitting adjacent cabinets or appliances. Lazy Susan and pull-out units need a little more.
On upper corner cabinets, leave 1–1.5″ (2.5–4 cm) in the inside dead corner so doors clear the neighboring cabinet.
A 36″ corner base needs at least a 36″ doorway to bring in — allow a 38″ (96 cm) opening if the cabinet has legs or trim.
A base corner unit projects the full 24″ (61 cm) depth along each wall; a corner sink base projects 36″ (91 cm). Upper corners stick out about 12″ (30.5 cm).
A corner pantry needs about 33–36″ (84–91 cm) on each wall and full 84–96″ (213–244 cm) height. Plan the door swing so it clears the adjacent runs.
Get the Most From the Corner
Once the cabinet fits, the right organizer turns that deep corner into usable storage: a Lazy Susan turntable for base corners, a blind-corner pull-out to reach hidden space, tiered shelf organizers for vertical room, and stackable under-sink drawers for corner sink bases.

Corner Cabinet Dimensions FAQs
How do you measure for a corner cabinet?
Measure from the inside corner of the wall along each wall to where the cabinet will end, and record both walls since corner runs are rarely equal. Include depth (24 inches standard for a base) and height (34.5 inches before the countertop), allow for a 1 to 1.5 inch counter overhang, and check the corner for squareness before ordering.
What are the standard blind corner cabinet dimensions?
The most common blind corner base cabinet is 36 inches wide by 24 inches deep by 34.5 inches high (about 91 by 61 by 87.6 cm). Wider models run 42 to 45 inches. It needs roughly 42 to 45 inches of wall space once you allow for door and pull-out clearance.
What are standard upper (wall) corner cabinet sizes?
Upper corner wall cabinets are usually 24 to 36 inches wide on each side with a standard depth of 12 inches and a height of 30 to 42 inches. A diagonal wall corner cabinet is typically 24 inches across the angled face. Leave 1 to 1.5 inches of inside dead-corner clearance for the doors.
How much wall space does a corner cabinet take?
A standard 36 inch blind corner cabinet takes at least 42 to 45 inches (107 to 114 cm) of wall space once you factor in clearance for the doors and pull-outs. A 42 inch unit needs about 45 inches.
How much clearance does a corner cabinet door need?
Allow at least 2 to 3 inches (5 to 7.5 cm) of clearance beside a corner cabinet door so it can swing open without hitting adjacent cabinets or appliances. Lazy Susan and pull-out units need a little more room for smooth operation.
What is the minimum size for a corner sink base cabinet?
A corner sink base cabinet generally needs a minimum of 36 by 36 inches to fit the sink and plumbing with enough working space. Allow an extra 2 to 3 inches around the cabinet for fixtures and countertop overhang.
What angle are corner cabinets?
Most diagonal corner wall and base cabinets are built at a 45 degree angle to sit neatly across the corner. Blind corner cabinets are built at a standard 90 degrees and extend along the adjacent wall instead.
What are corner pantry cabinet dimensions?
Corner pantry cabinets are commonly 33 to 36 inches wide on each wall side and 84 to 96 inches tall (about 213 to 244 cm). They create a walk-in or angled full-height pantry for maximum corner storage.
What is the standard corner cabinet drawer size?
Corner cabinet drawers typically range from 15 to 24 inches wide, depending on the cabinet style and whether it is an L-shaped or diagonal unit. Pull-out corner shelves usually need a minimum door width of 15 inches, with 18 inches preferred for easier access.
What are corner cabinet dimensions in cm and feet?
A standard 36 by 36 inch corner base cabinet is about 91 by 91 cm, or roughly 3 by 3 feet. Depth is 24 inches (61 cm) and height is 34.5 inches (87.6 cm) before the countertop. In millimeters, 36 inches is 914 mm.
How big a doorway do you need for a 36-inch corner base cabinet?
A 36 inch corner base cabinet needs at least a 36 inch wide doorway to bring it in. If the cabinet has legs or additional trim, a 38 inch (96 cm) doorway is recommended.
What’s the difference between a blind and a diagonal corner cabinet?
A diagonal corner cabinet has a 45 degree angled front and sits symmetrically across the corner, so its storage is easy to see and reach. A blind corner cabinet has a flat 90 degree front and extends deep along the adjacent wall, hiding storage behind the neighboring run — which is why a pull-out organizer helps.
