Cabinet dimensions come up the moment you start planning a kitchen remodel, a bathroom refresh, or even a simple pantry upgrade — and the numbers scattered across manufacturer catalogs rarely line up in one place. This guide pulls standard kitchen, bathroom, and storage cabinet sizes into a single reference chart, walks through exactly how to measure your own space, and flags the mistakes that trip up first-time remodelers most often. Whether you’re replacing one cabinet or planning an entire kitchen, you’ll leave with the numbers you actually need.
Standard Cabinet Dimensions Chart
These are the sizes used across most stock and semi-custom cabinet lines. Treat them as a reliable starting point — always confirm against your chosen manufacturer’s spec sheet before ordering.
| Cabinet Type | Height | Depth | Width Range | Notes |
|---|---|---|---|---|
| Kitchen Base Cabinet | 34.5″ (36″ with countertop) | 24″ | 12–48″ (3″ increments) | Height excludes countertop unless noted; toe kick adds ~4.5″ at the base |
| Kitchen Wall Cabinet | 12, 15, 18, 24, 30, 36 or 42″ | 12″ (up to 24″ for full-depth) | 12–36″ | Mount 15–20″ above the countertop for comfortable clearance |
| Kitchen Tall / Pantry Cabinet | 84–96″ (3″ increments) | 12″ or 24″ | 12–36″ | Match depth to the adjacent base or wall cabinet run |
| Bathroom Vanity (Single Sink) | 32–36″ (comfort height) | 18–21″ | 24–48″ | Leave 30″+ of width for comfortable drawer and door swing |
| Bathroom Vanity (Double Sink) | 32–36″ | 21–24″ | 60–72″ | Aim for 30″+ centerline spacing between the two sinks |
| Linen / Storage Cabinet | Commonly 68–84″ tall (freestanding units) | 14–24″ | 15–30″ | Depth often matches the adjacent vanity, or as little as 12″ for slim hallway units |
Reading the Chart: Where Each Measurement Is Taken
The numbers above only help if you’re measuring the same way the chart does. Here’s what each dimension actually refers to on a real cabinet:
- Height is measured from the floor to the top of the cabinet box — not the countertop. On a base cabinet, that includes the toe kick at the bottom (about 4.5″) plus the box itself.
- Depth runs from the wall to the front edge of the cabinet box, excluding door thickness and any countertop overhang. Add roughly 1 to 1.5 inches once the countertop is installed.
- Width is measured across the front of the cabinet, face frame included. Stock cabinets are sized in 3-inch increments so they can be mixed and matched along a wall without odd gaps.
How to Measure Your Own Space
Whether you’re replacing a single cabinet or planning a full run, the process is the same. Work through it in order and you’ll avoid the most common ordering mistakes.
- Gather your tools. You’ll need a steel tape measure, a notepad or phone, and a level. Skip a fabric or cloth tape — it stretches and throws off precision measurements.
- Measure the width. Measure wall-to-wall at three points — top, middle, and bottom of the opening — and use the smallest number. Walls are rarely perfectly straight.
- Measure the height. For base cabinets, measure from the finished floor to where the countertop will sit. For wall cabinets, measure from that same countertop line up to the ceiling or soffit.
- Measure the depth. Measure from the back wall to where you want the front of the cabinet to land, accounting for any baseboard or trim that sticks out.
- Note obstacles. Mark the location of outlets, switches, plumbing lines, and windows relative to your measurements so the new cabinet doesn’t collide with any of them.
Real Room Examples
Standard sizes are a starting point — here’s how they typically play out in actual rooms.
- Small galley kitchen: 12–24″ wide base cabinets on each wall, 12″-deep wall cabinets to protect the narrow walkway, and a slim 12″-deep pantry column if space allows.
- Medium kitchen: A mix of 24–36″ base cabinets, standard 24″-deep wall cabinets, and one 24–30″-wide pantry cabinet for everyday storage.
- Large kitchen: 36–48″ base cabinets around an island, full-height 36″-wide pantry cabinetry, and wall cabinets extended to 42″ for ceiling-height runs.
- Powder room / guest bath: A single 24–30″ vanity at 18–20″ depth keeps the room open in a tight footprint.
- Master bath: A 60–72″ double vanity at 21–24″ depth, often paired with a matching linen cabinet for towel and toiletry storage.
- Apartment or hallway: A slim 15–18″-wide, 12″-deep linen cabinet fits where a full closet won’t.
Professional Tips
- Designer clearance rule: Keep at least 18–21″ of open floor space in front of any cabinet, vanity, or drawer so it opens without hitting a wall, appliance, or fixture.
- Space-saving pick: In tight kitchens, choose 12″-deep wall cabinets over 24″ and a 18–20″-deep vanity in small bathrooms — the difference is noticeable in a narrow room.
- Luxury upgrade: Floor-to-ceiling pantry cabinetry (90–96″) and a furniture-style vanity with a 24″+ depth read as custom-built even when built from stock sizes.
- Budget-friendly approach: Sticking to standard 3″-increment stock widths, rather than custom sizing, keeps costs down and shortens lead times significantly.
- Mistake to avoid: Ordering wall cabinets at a uniform height without checking the soffit or ceiling line first — an unplanned gap above the cabinets is one of the most common kitchen remodel regrets.

What is the standard height of a kitchen base cabinet?
Standard kitchen base cabinets are 34.5 inches tall, measured from the floor to the top of the cabinet box, not including the countertop. Once a typical 1.5-inch countertop is added, the finished height comes to 36 inches, which is the industry-standard counter height.
How deep are kitchen base cabinets?
Standard base cabinet depth is 24 inches, measured from the wall to the front of the cabinet box. With a countertop overhang, the finished depth typically reaches 25 to 26 inches.
What width sizes do kitchen base cabinets come in?
Stock base cabinets are generally available from 9 to 48 inches wide, in 3-inch increments. The most common widths are 12, 18, 24, 30, 36, and 48 inches.
How high should wall cabinets be above the countertop?
Most kitchens leave 15 to 20 inches of clearance between the countertop and the bottom of the wall cabinets, giving enough room to work while keeping upper storage within easy reach.
What are standard kitchen wall cabinet heights?
Wall cabinets commonly come in 12, 15, 18, 30, 36, and 42-inch heights, with 30 and 36 inches being the most typical for kitchens with 8-foot ceilings.
How deep are wall cabinets compared to base cabinets?
Wall cabinets are shallower than base cabinets, typically 12 inches deep versus 24 inches for base cabinets. This keeps them from crowding the workspace below and blocking sightlines across the kitchen.
What is the standard depth of a pantry or tall kitchen cabinet?
Tall pantry cabinets are usually built to a depth of 12 or 24 inches so they line up flush with adjacent wall or base cabinets. Heights typically range from 84 to 96 inches, in 3-inch increments.
What is the toe kick height on a base cabinet?
The toe kick, the recessed space at the base of a cabinet, is standard at about 4.5 inches tall and 3 inches deep, allowing feet to tuck underneath while standing at the counter.
What is the standard depth of a bathroom vanity?
Standard bathroom vanity depth is 21 inches. Compact vanities for tight bathrooms run 18 to 20 inches deep, while some larger vanities extend to 22 to 24 inches.
How tall should a bathroom vanity be?
Older builder-grade vanities sit at 30 to 32 inches tall. Current “comfort height” vanities, which align with kitchen counter height, run 34 to 36 inches and have become the more common choice.
What is the maximum height allowed for an ADA-compliant vanity?
For ADA compliance, the counter or rim of an accessible lavatory can be no higher than 34 inches from the floor, which is lower than the 34- to 36-inch comfort-height range used in most standard vanities.
What size vanity do I need for a double sink?
Double-sink vanities generally start around 60 inches wide and commonly range up to 72 inches, which gives roughly 30 inches or more of centerline spacing between each sink.
What is the smallest standard bathroom vanity size?
A 24-inch-wide vanity is the smallest common full-size option and is typically used in powder rooms and small guest bathrooms where floor space is limited.
How much clearance should I leave in front of a vanity?
Plan for at least 18 to 21 inches of clear floor space in front of a vanity so doors and drawers open comfortably without hitting a wall, tub, or toilet.
How wide is a standard linen cabinet?
Freestanding linen cabinets are typically 24 to 30 inches wide, though narrow models can run as slim as 15 inches and larger units can exceed 36 inches for bigger bathrooms or hallways.
Are cabinet dimensions always exactly standard?
No. The figures in this guide reflect common stock sizes used across the cabinet industry, but exact dimensions vary by manufacturer, and semi-custom or custom cabinetry can be built to nearly any size.
How do I measure an existing cabinet for a replacement?
Measure the width, height, and depth of the existing cabinet box itself, not including doors, handles, or trim, and note the location of any plumbing, outlets, or appliances that the new cabinet needs to clear.
Do cabinet height measurements include the countertop?
Usually not. Cabinet height figures typically refer to the cabinet box only. Add the countertop thickness, commonly 1.5 inches, to get the finished counter height most manufacturers quote.
What depth should a corner or blind base cabinet be?
A blind corner cabinet keeps the standard 24-inch depth along the wall it runs against, while its face width facing the room is typically 36 inches, with 42 to 48 inches from the back corner to the outer edge of that face.
Can I customize standard cabinet sizes?
Yes. Beyond stock sizes, most cabinet lines offer semi-custom options in smaller increments, and fully custom cabinetry can be built to match nearly any width, height, or depth a space requires.
Bottom Line
Standard cabinet sizes give you a reliable starting point — 34.5″ base cabinets, 24″ base depth, 21″ vanity depth — but the only measurements that matter for your project are the ones you take yourself. Measure your space, check it against this chart, and confirm final numbers against your chosen manufacturer before you order.
