Kitchen Base Cabinet Sizes Chart for Choosing Floor Units

Key takeaways

• Most kitchen base cabinets follow standard height and depth, so focus on getting the widths right around sinks, hobs and appliances.
• Always add fillers and end panels into your measurements; a run of cabinets rarely equals the wall-to-wall width exactly.
• Check appliance sizes first, then build your cabinet width chart around them, leaving 5–10 mm clearance where possible.
• In small kitchens, slim freestanding floor cupboards such as a compact floor cabinet with drawer and shelves can add storage without altering built-in units.
• Use simple width formulas and a written size chart for each wall, rather than guessing as you go along.

Why this category matters

Base cabinets do most of the hard work in any kitchen. They support the worktops, house sinks and hobs, hide plumbing and electrics, and provide the bulk of your storage. If the cabinet sizes are off by even a few millimetres in the wrong place, you can end up with doors that clash with appliances, drawers that do not open properly, or a sink that sits oddly off-centre. Getting sizes right is less about perfectionism and more about everyday usability.

Most manufacturers keep to broadly similar height and depth standards, which makes worktop and appliance pairing easier. Where things vary is width and how those widths are combined along each wall. A simple base cabinet size chart for your own kitchen – listing each unit in order with its width – turns a confusing jigsaw into a clear plan. You can see at a glance where a 300 mm pull-out, a 600 mm sink unit, or an 800 mm pan drawer stack will fit.

Even if you are not planning a full fitted kitchen, understanding common base cabinet dimensions helps when choosing freestanding storage units. A tall, slim cupboard that roughly matches built-in depths will sit more neatly in a run than a random piece that sticks out or sits back too far. A well-chosen freestanding cupboard can act almost like another fitted base unit, adding valuable storage in a tight space.

Finally, correct sizing matters for long-term flexibility. If you stick close to standard widths – especially 300, 400, 450, 500, 600, 800 and 1000 mm – it is much easier to replace a unit, change a door style, or add internal organisers later. Odd sizes and improvised fillers may look fine on installation day but can limit your future options.

How to choose

The best way to choose kitchen base cabinet sizes is to work from fixed points outwards. Start with items that cannot easily move: doors, windows, services (water, waste, gas, electrics), and any large appliances you already own. Mark these on a simple plan, then build your cabinet size chart around them. Think of each wall as a total width that you are dividing up into units, fillers and end panels.

Next, sketch a basic workflow: fridge to sink to hob to prep space. The run between sink and hob is especially important, as this is where you will spend most of your time. Aim for a comfortable mix of widths here – for example, a 600 mm sink unit, a 400 mm drawer unit for utensils, and an 800 mm pan drawer or cupboard for pots. Once you know the function of each stretch of worktop, it becomes easier to assign the right cabinet sizes beneath.

For sink runs, measure your chosen sink or the cut-out size if you have it. Many sinks suit a 600 mm base unit, but wider bowls and drainers may call for 800 or 900 mm. Add in a little side space for tap holes and for the worktop to overhang neatly. For cooking zones, note whether your hob will sit above a standard cabinet or a built-in oven. In both cases, allow for the manufacturer’s ventilation clearances when deciding cabinet size.

Depth is usually more straightforward. Standard base cabinet depth tends to sit just under the worktop depth, with a small service void at the back. Freestanding cabinets like a slim pantry-style cupboard with adjustable shelves are often designed to echo this depth so they tuck neatly alongside existing runs. Check depth carefully if you plan to place a freestanding unit against the same wall as fitted cabinets so you avoid awkward overhangs or gaps.

A simple but powerful rule: list every wall run as a sum. For example, 2300 mm wall = 50 mm filler + 600 mm dishwasher + 600 mm sink unit + 600 mm cupboard + 50 mm filler + 400 mm panels and scribes. If the total does not match the wall, adjust on paper before you order anything.

Common mistakes

One of the biggest mistakes is forgetting to allow for fillers and scribes. Walls are rarely perfectly straight, and you do not want your cabinets hard against a side wall where doors and drawers could scrape. A narrow filler – sometimes 20–50 mm – gives you flexibility to cope with wonky plaster and out-of-square corners. Leave space for end panels too, especially if you want a neat finished edge to a run or island.

Another common issue is centring. People naturally want the sink centred under a window, or the hob centred on a feature wall, but then choose cabinet widths that make this impossible without uneven slivers of worktop on either side. It is worth playing with combinations of 400, 500, 600 and 800 mm units on paper until you get both a practical layout and balanced centring of key features.

Height mistakes also creep in, usually where flooring is changed after cabinets are measured. If you are planning new flooring, make sure your base cabinet height plus plinth plus worktop will still give you a comfortable final worktop height once the finished floor is in. This matters especially around tall freestanding cabinets, where the top edge alignment with neighbouring units affects the overall look.

Finally, many people either over- or under-estimate their need for full-height storage. A huge larder can be wonderful, but if it steals too much under-counter space you may lack drawers for everyday utensils and pans. Sometimes the answer is a modest freestanding cabinet, like a floor-standing cupboard with louvred doors and open compartments, placed where it will not disturb your main workflow.

Top kitchen base cabinet options

Alongside built-in units, many people rely on freestanding floor cabinets to plug awkward gaps, add pantry-style storage, or create a mini prep zone in a dining area or utility room. The following options give you a sense of how different sizes and configurations work in practice, and how to read their measurements so they fit smoothly into your overall plan.

All three examples are freestanding floor cupboards designed to sit at roughly worktop-adjacent height and depth, making them useful either as standalone storage or as extensions of a fitted run. The dimensions matter: a few centimetres narrower or shallower can determine whether a piece feels integrated or looks like an afterthought.

Compact Floor Cabinet with Drawer and Shelves

This freestanding cupboard offers a familiar base-cabinet format: a pair of doors concealing storage below, an upper drawer for smaller items, and open shelves to one side. Its footprint is compact enough to slip into tighter spaces such as beside a fridge, near a back door, or in a small breakfast nook. The combination of closed and open storage means you can hide clutter while keeping everyday pieces within easy reach.

From a sizing perspective, this unit works well where you would otherwise consider a 400–600 mm built-in base cabinet. It can create a small extra run of worktop if you add a matching surface, or stand alone in a hallway or utility as a multi-purpose storage piece. The open shelving also makes it easier to cope with slightly awkward wall widths, because a few millimetres of mismatch between shelves and skirting is less noticeable than with a fully enclosed carcass.

Pros include the flexible storage mix and a modest footprint that suits smaller floor areas. On the downside, the open side does not suit those who prefer everything hidden, and it will not carry the same load as a fully built-in base unit. If you are looking at compact freestanding base cabinets, the Multigot freestanding cupboard with drawer and shelves is a useful example of how a narrower floor cabinet can still add meaningful storage. You can also browse a broader range of similar kitchen floor cabinets in popular widths to compare dimensions.

Slim Pantry-Style Floor Cupboard

A taller, slim floor cupboard effectively acts like a mini pantry. With doors concealing several shelves and the option to adjust shelf heights, it is well suited to storing dry goods, small appliances or tableware. The key dimension to consider here is depth: many of these cupboards are designed close to standard base cabinet depth so they line up reasonably well with existing worktops or can sit flush against a free wall.

Because this style of cabinet tends to be taller than standard base units, it can add vertical presence where you have dead wall space. In layout terms, think of it as an end stop to a run, or as a standalone storage zone opposite your main worktops. Check the width carefully; if it approximates one of the standard cabinet widths (for example, around 600 mm), it is easier to slot into your mental size chart when planning the overall room.

The strengths of a slim pantry-style cupboard are clear: generous storage, adjustable shelves, and a small footprint relative to capacity. The trade-off is that deep shelves can become hard to reach at the back if they are too tall above the floor. When considering units of this type, the Jehiatek freestanding kitchen pantry cupboard is an example where the width and depth are carefully balanced for typical kitchen spaces. You can also compare it with other tall floor cabinets in similar height ranges to see how dimensions affect capacity.

Floor-Standing Cupboard with Louvered Doors

This style of cabinet combines enclosed cupboard space with a couple of open compartments, usually at the top or side. The louvered doors add ventilation, which can be handy if you plan to store items that benefit from airflow, such as vegetables in baskets, cleaning supplies, or small appliances that are used frequently and may still retain a bit of warmth after use.

Dimensionally, these cabinets often align with a typical base unit width, making them easy to visualise as part of your size chart. They are especially useful against shorter walls where a full run of cabinets is not practical, or in dining areas where you want something that feels lighter than a solid block of doors. The open sections help visually break up the mass, which can be important in smaller or lower-ceilinged rooms.

On the plus side, you get a mix of display and hidden storage, with a footprint that still respects standard base cabinet depths. The compromise is that louvered doors have a more distinctive style, which may not suit every kitchen. A good example is the VASAGLE floor-standing cabinet with louvered doors, which shows how a single floor unit of intermediate width can provide versatile storage while still fitting comfortably into a standard room layout.

Planning your base cabinet size chart

Putting everything together, it helps to think in terms of repeatable steps. First, measure each wall from finished surface to finished surface. Note any radiators, boxing, pipework or nibs that steal usable space. Next, write each wall as a total width at the top of a page, then beneath it list your proposed cabinets in order with their widths. Be sure to insert nominal fillers and end panels where runs meet walls or other furniture.

For example, a simple straight run might look like this in your notes: 3000 mm wall = 50 mm filler + 600 mm integrated dishwasher + 600 mm sink base + 800 mm pan drawer unit + 400 mm pull-out + 50 mm filler + 100 mm panels and scribes. Adjust the numbers until the sum equals your wall width. If you end up with an awkward leftover measurement, try swapping a 400 mm unit for a 500, or changing the size of your fillers slightly.

Once you are happy with each wall, transfer the information into a clean chart. A simple table with columns for position number, unit type, width and notes is enough. Include appliances and freestanding pieces as well as fixed cabinets, so you have a full picture of what occupies each stretch of wall. This chart becomes your reference when ordering, checking deliveries and guiding installers.

If you would like deeper guidance on standard dimensions, you can pair this approach with a dedicated standard kitchen base cabinet sizes guide, which digs further into typical heights and depths and how they align with worktops and appliances.

Sizing around sinks, cookers and appliances

Appliances are usually the least flexible parts of a layout, so they deserve their own place on your size chart. For dishwashers, washing machines and freestanding cookers, note the manufacturer’s width and add a few millimetres each side if possible. Standard units often assume a 600 mm nominal width, but modern appliances can vary slightly. For built-in ovens under a hob, be sure your chosen base cabinet is designed to accept an oven box and offers the required ventilation clearances.

Sink cabinets warrant special attention. Measure the sink body and any drainers, then ensure the base cabinet is wide enough to house the bowl while leaving side support for the worktop. A common quick-fit formula is: sink base width ≥ sink bowl width + 100–150 mm. If you want a double bowl or wider drainer, consider 800 or 900 mm base units rather than forcing a large sink into a tight 600 mm carcass.

For hobs, check whether they will sit over drawers, an oven or a blank cabinet. Many modern hobs can sit above drawer units if they are designed for it, but you still need depth clearance and ventilation. Check the hob cut-out size against the cabinet and worktop depths to ensure you will not clash with back rails or drawer boxes.

Fridge-freezers, tall larders and freestanding pantry cabinets like the Jehiatek tall cupboard are best treated as their own modules on your chart. Give them a full line with width and height, and note any doorswing clearance required so cabinet doors and appliance doors do not collide.

Coping with wall irregularities and corners

Very few kitchens have perfectly straight, square walls. This is where your fillers, corner solutions and end panels earn their keep. In internal corners, use corner base units or a blind corner arrangement that builds in a bit of adjustment to absorb wall irregularities. Never run two full-depth cabinets directly into each other; you will end up with clashing doors and unusable dead space.

Along wavy or out-of-plumb walls, it is often better to keep the cabinet run straight and let the filler or scribe panel vary in width to meet the wall neatly. This keeps your worktop straight and level, which matters more visually than matching every bump in the plaster. Your size chart can include a note column where you mark walls that are particularly uneven so you and your installer expect some on-site adjustment.

External corners, such as a peninsula or island, usually look better with end panels that wrap around the cabinet sides. Remember to include the thickness of these panels in your size sums; a pair of 20 mm panels can easily add 40 mm to the overall run, which could be the difference between a comfortable fit and a tight squeeze.

In narrow galley spaces, you may decide to keep one side to full-depth cabinets and use shallower floor-standing units on the opposite wall. Freestanding cupboards like the VASAGLE louvered-door cabinet can sometimes work in this role, offering storage without encroaching as far into the walkway as a full-depth base run.
