In short
Standard base cabinets are 34.5″ tall (36″ with worktop), 24″ deep; wall cabinets 12–42″ tall, 12″ deep, mounted 18″ above the counter; tall/pantry cabinets 84–96″ tall, 24″ deep. Made-to-measure units close the gaps.
Kitchen cabinet measurements decide whether a kitchen fits, works and installs cleanly — or whether it ends in costly modifications on site. Getting the dimensions right before designing is the single cheapest insurance a project buys, because a measurement fixed on a drawing costs nothing and a measurement discovered wrong after production costs a refit. For the hotel, aparthotel and project kitchens we build in our contract kitchen cabinet workshop, the standard sizes have to fit the real space to the millimetre and repeat identically across a building. This guide sets out the standard kitchen cabinet dimensions — base, wall and tall — the clearances around them, and how to measure a kitchen properly before a single unit goes into production.
Most kitchens rest on a small set of standard cabinet sizes, adjusted to the room with made-to-measure units where a fixed module leaves a gap. Knowing those standards — the heights, depths and widths, and the clearances between cabinets and appliances — is what lets a buyer brief, check and sign off a kitchen with confidence. The sections below give the dimensions, the spacing, the construction details, and the method for measuring, then close on getting the measurements right for a contract project.
Why Measurements Come First
Measurements lead every kitchen because everything else depends on them. The layout, the appliance fit, the worktop, the cost — all follow from accurate dimensions, and an error in the measurements multiplies through the whole project. Measuring before designing, rather than designing and forcing the measurements to fit, is the order that prevents the expensive mistakes.
Measure Before You Design
The phrase “measure before designing” captures a real discipline: take the room’s true dimensions first, then design the kitchen to them, never the other way round. Designing a kitchen on assumed sizes and discovering on site that a run is two inches too long, a cabinet fouls a window, or an appliance will not fit is the most common and costly kitchen mistake. Accurate measurements at the start let the design resolve every clash on paper, where a change costs a redraw rather than a rebuild. For a project repeated across many rooms, this discipline is not optional — one bad assumption repeats everywhere.
The Three Cabinet Types
Almost every kitchen uses three cabinet types, and the standard dimensions follow each. Base cabinets sit on the floor, carry the worktop and do the heavy storage; wall cabinets mount above for lighter, accessible storage; and tall cabinets run floor to near-ceiling as pantries or to house tall appliances. Each has its own standard height, depth and width range, and knowing them is the foundation of every measurement that follows. The chart and table below set all three out together.
Quick answer
What are standard kitchen cabinet sizes? Standard base cabinets are 34.5″ tall (36″ with the worktop) and 24″ deep, in widths from 9 to 48″. Standard wall cabinets are 12 to 42″ tall and 12″ deep, mounted 18″ above the worktop. Tall pantry or utility cabinets run 84 to 96″ tall and 24″ deep. These standards cover most kitchens, with made-to-measure units closing any gaps the fixed sizes leave.
Standard Cabinet Dimensions
The standard kitchen cabinet dimensions are an industry baseline that most kitchens follow, residential and contract alike. They exist because they suit the human body and common appliances, and working to them keeps a kitchen ergonomic and the components compatible. The chart below shows the three types to scale, and the sections set out each in detail.
Base Cabinet Dimensions
Base cabinets are the foundation of the kitchen, and their height follows ergonomics. A standard base cabinet carcass stands 34.5″ tall, and with a worktop on top it reaches the standard 36″ working height that suits most people at a counter. The standard depth is 24″, deep enough to carry a worktop with a small overhang and to house appliances, though custom runs sometimes reach 27″. Widths come in modules — commonly 12, 15, 18, 24, 30, 33, 36 and 48″ — so a run draws from a combination that fills the wall. The base cabinets carry the most weight and the most use, so their measurements anchor the whole kitchen.
Wall Cabinet Dimensions
Wall cabinets mount above the worktop for accessible storage, and their dimensions balance reach against capacity. Standard heights run 12, 15, 18, 24, 30, 36 and 42″, with 30″ and 36″ the common choices and 42″ reaching nearer the ceiling for extra storage. The standard depth is 12″ — shallower than the base so the units sit above the worktop without crowding the workspace — though 15″ appears for deeper storage. The critical measurement is the gap between worktop and wall cabinets: 18″ is the recommended standard, enough to use the counter freely and fit small appliances beneath. Above a hob, leave 24 to 30″ to the cabinets for safety.
Tall and Pantry Cabinet Dimensions
Tall cabinets run from the floor to near the ceiling, used as pantries, utility cabinets or housings for ovens and fridges. Standard heights are 84, 90 or 96″, chosen to suit the ceiling and to align with the top of the wall cabinets for a level run. The standard depth matches the base at 24″, though narrower 12 or 18″ versions suit tight spaces, and common widths are 18, 24 and 36″. A tall cabinet packs the most storage into the smallest footprint, which makes it valuable in compact and aparthotel kitchens. Where one sits beside a fridge, allow clearance for the doors to swing and for ventilation.
The table below collects the standard dimensions in both imperial and metric, for quick reference across a project.
| Cabinet type | Height | Depth | Width options | Key clearance |
|---|---|---|---|---|
| Base | 34.5″ / 880 mm (36″ with worktop) | 24″ / 610 mm | 12–48″ | 36″ working height |
| Wall | 12–42″ / 300–1070 mm | 12″ / 305 mm | 9–48″ | 18″ above worktop |
| Tall / pantry | 84–96″ / 2130–2440 mm | 24″ / 610 mm | 18, 24, 36″ | Door-swing + ventilation |
| Toe kick | 4.5″ / 115 mm high | 3″ / 75 mm recess | — | Comfortable standing |
Why 34.5 plus a worktop, not 36 — the number that confuses buyers
A frequent source of confusion is that a base cabinet measures 34.5″ while the kitchen works at 36″. The cabinet carcass is deliberately 34.5″ so that a standard 1.5″ worktop brings it to the 36″ working height that suits most people at a counter. Quote the carcass height and the finished height separately and the numbers stop clashing. It matters in practice because the worktop thickness is part of the calculation: a thicker stone top or a thin laminate changes the finished height, and a kitchen specified to 36″ finished, not 36″ carcass, is the one that ends up at the right level. On a project, fixing the finished working height and working back to the carcass is what keeps every run consistent.
Clearances and Spacing
Cabinet sizes are only half the measurement; the space around them decides whether a kitchen works. Clearances for worktops, appliances and walkways turn a set of cabinets into a usable kitchen, and skipping them is how a technically correct layout becomes unusable in practice.
Worktop and Landing Space
A kitchen needs clear worktop to function, and standards set the minimums. A main preparation area wants at least 36″ of uninterrupted worktop, and every appliance needs landing space beside it — 12 to 15″ next to a hob and oven for setting down hot pans, and space on each side of the sink, commonly 24″ on one side and 18″ on the other. Skimping on landing space makes a kitchen feel cramped and unsafe however good the cabinets are. Planning these clearances into the layout, alongside the cabinet sizes, is what gives a kitchen room to work.
Appliance Clearances
Appliances set hard clearance rules that the cabinet measurements have to respect. A dishwasher needs about 24″ clear beside the sink for loading; an oven wants landing space either side; a refrigerator needs roughly 36″ of aisle in front for its doors; and a microwave sits comfortably with its base around 54″ from the floor. Each appliance also has its own width, depth and ventilation needs that the surrounding cabinets must accommodate. Confirm the exact appliance dimensions before sizing the cabinets around them, because an appliance that will not fit, or whose door fouls a cabinet, is the clash that most often surfaces on site.
Walkways and the Work Triangle
The space to move and work is the last clearance, and it shapes the whole plan. Walkways need at least 42″ of width for comfortable movement, rising where two people work or traffic passes through; around a kitchen island, allow 42″ of clearance on every side. The classic work triangle — keeping sink, hob and refrigerator within an efficient reach of one another, broadly 4 to 9 feet apart — keeps a kitchen functional, and the cabinet layout has to serve it. Measure the walkways and the triangle, not just the cabinet runs, so the finished kitchen flows.
Thickness, Toe Kick and Construction Details
A few smaller measurements decide quality and comfort as much as the headline sizes. Carcass thickness, the toe kick and the way a cabinet front splits all carry standards worth knowing before designing.
Carcass Thickness: Half-Inch or Three-Quarter
A common question is whether kitchen cabinets use half-inch or three-quarter-inch board. The answer for a quality kitchen is three-quarter-inch (18 mm) for the carcass and structural panels, which holds screws, carries worktops and resists sagging far better than the half-inch (12 mm) board used in cheaper kitchens. Half-inch board appears in backs and some internals where it carries no load, but a carcass built throughout in thin board flexes and loosens under use. The board thickness is a measurement that signals build quality, and the material behind it — covered in our cabinet material guide — matters as much as the thickness. For a contract carcass, three-quarter-inch is the standard to specify.
Toe Kick and Plinth
The toe kick is the recess at the base of a cabinet that lets you stand close to the worktop without stubbing your feet, and its measurements are standard: about 4.5″ high and 3″ deep. That recess matters more than its size suggests — without it, you stand back from the counter and lose comfort and reach at every task. The plinth that forms it also levels the run on an uneven floor and seals the base against cleaning. Include the toe kick in the height calculation, because it is part of the 34.5″ base cabinet, not an addition to it.
The One-Third Rule and Drawer Splits
The one-third rule is a useful proportion for cabinet fronts: splitting a run or a tall bank so that drawers and doors fall into roughly one-third and two-third divisions reads as balanced and stores well, rather than splitting everything in half. Applied to a base run, it often means a shallower top drawer over a deeper one, or a drawer stack beside a door cabinet in pleasing proportion. It is a guideline, not a rule, but it explains why some cabinet layouts look right and store well while others feel awkward. For a project, settling these splits as a standard keeps every kitchen consistent and considered.
How to Measure a Kitchen
With the standards understood, measuring the actual room is the practical step. A careful, methodical measurement of the space is what lets a design fit it, and a few habits prevent the errors that cause refits.
Measure the Space
Start in one corner and measure along each wall in turn, recording the full length of every wall and the ceiling height, which sets the tall-cabinet options. Measure twice and record in a consistent unit, noting dimensions clearly on a sketch of the room. Take the ceiling height in several places, since floors and ceilings are rarely perfectly level, and note the lowest point that the cabinets must clear. An accurate set of wall lengths and heights is the base layer every other measurement sits on.
Mark Doorways, Windows and Services
Onto the wall measurements, mark everything that constrains the cabinets: doorways and their swing, windows and their sill heights, and the position of every electrical outlet, switch, water supply, waste and gas point. These services decide where sinks, hobs and appliances can go, and a cabinet planned over an immovable pipe or a window is the clash that wastes a run. Recording the services accurately at the measuring stage lets the design route around them, rather than discovering them when the kitchen will not fit.
Common Measurement Mistakes
A handful of mistakes cause most kitchen measurement problems. Ignoring ceiling height leaves tall cabinets that do not fit; forgetting appliance door clearances leaves a fridge or oven that cannot open; overlooking baseboard or skirting trim throws the run out at the wall; misjudging corner cabinets wastes the hardest space in the kitchen; and skipping the wall stud or fixing positions leaves wall cabinets with nothing solid to hang from. Each is avoidable with a careful measure. Double-checking every dimension before ordering, especially for custom cabinets, is the habit that prevents delays and unexpected costs.
In a project, one wrong measurement repeats across every room
For a single home, a measurement error is one annoying refit. For a hotel or aparthotel building dozens or hundreds of identical kitchens, the same error multiplies across every room — a tall cabinet an inch too high, a clearance an inch too tight, a fridge housing that fouls a door, repeated at scale. That is why a contract kitchen settles its measurements on a prototype: the maker builds one kitchen to the drawings, checks it in the actual room, and signs it off before the production run. A second discipline matters internationally — many projects mix imperial and metric, and a kitchen specified in inches but installed to a metric drawing is a recipe for drift. Fix the units, prove the dimensions on a prototype, and the whole building installs cleanly.
Measurements for a Contract Project
For a project, measurements move from a single kitchen to a repeatable standard. Working from standard modules to a made-to-measure fit, and specifying the dimensions clearly with the manufacturer, is what turns measurements into a consistent run of kitchens.
Standard Modules vs Made-to-Measure
Contract kitchens use the standard module sizes as a base but fit each run to the real space. Standard widths and heights keep components compatible and cost controlled, while made-to-measure units close the gaps a fixed range leaves — a filler here, a non-standard width there — so the kitchen fits the room exactly rather than leaving awkward gaps. The art is using standard sizes wherever possible and custom only where the space demands, which balances fit against cost. A contract maker works from the project’s drawings to combine both into a clean, gap-free run.
Specifying Dimensions with a Manufacturer
A contract manufacturer turns a measured space into a cabinet schedule: every unit sized, every clearance checked, every service accounted for, then prototyped and signed off before production. As a workshop we build contract kitchen cabinets to the project’s exact drawings — standard modules and made-to-measure units combined to fit the room — for hotels, aparthotels, villas and projects, on FOB or CIF terms with a four-to-eight-week lead time and a two-year warranty, delivered worldwide. For the full specification picture, our contract kitchen cabinet guide covers boards, doors, layouts and sourcing alongside these measurements.
Kitchen cabinet measurements come down to a clear method: know the standard dimensions for base, wall and tall cabinets, plan the clearances around appliances and walkways, respect the construction details from carcass thickness to toe kick, measure the real room carefully before designing, and combine standard modules with made-to-measure units for an exact fit. Do that and a project’s kitchens install cleanly, room after room; skip it and one wrong dimension repeats across the building. Measure before you design, prove it on a prototype, and the kitchen fits every time.
Frequently Asked Questions
What are standard kitchen cabinet sizes?
Standard base cabinets are 34.5″ tall (36″ with the worktop) and 24″ deep, in widths from 9 to 48″. Standard wall cabinets are 12 to 42″ tall and 12″ deep, mounted 18″ above the worktop. Tall pantry cabinets run 84 to 96″ tall and 24″ deep. These standards cover most kitchens, with made-to-measure units closing any gaps the fixed sizes leave.
Are all kitchen base cabinets 24 inches deep?
Most standard base cabinets are 24″ deep, which carries a worktop with a small overhang and houses standard appliances. Some custom designs reach 27″ for deeper storage, and shallower units exist for tight spaces. Wall cabinets, by contrast, are usually 12″ deep so they sit above the worktop without crowding the workspace. For a project, confirm the depth against the appliances and worktop before sizing.
How do I measure for kitchen cabinets?
Start in one corner and measure each wall in turn, recording every wall length and the ceiling height. Mark doorways, windows and the position of all services — outlets, water, waste and gas — on a sketch, and take the ceiling height in several places since rooms are rarely level. Measure twice, note the lowest clearances, and double-check every dimension before ordering, especially for custom cabinets.
Are kitchen cabinets 1/2 or 3/4 inch thick?
A quality kitchen uses three-quarter-inch (18 mm) board for the carcass and structural panels, which holds screws, carries worktops and resists sagging. Half-inch (12 mm) board appears in backs and some non-load-bearing internals, but a carcass built throughout in thin board flexes and loosens under use. For a contract carcass, three-quarter-inch is the standard to specify.
What is the 1/3 rule for cabinets?
The one-third rule is a proportion guideline: splitting a cabinet run or a drawer bank into roughly one-third and two-third divisions reads as balanced and stores better than splitting everything in half. Applied to a base run it often means a shallower top drawer over a deeper one. It is a guideline rather than a strict rule, but it explains why some cabinet layouts look right and store well.
How much space should there be between base and wall cabinets?
The recommended standard gap between the worktop and the bottom of the wall cabinets is 18″, which lets you use the counter freely and fit small appliances beneath. Above a hob or cooktop, increase the clearance to 24 to 30″ for safety. Getting this gap right keeps the kitchen both usable and safe, so it is one of the key measurements to fix early.
