10 Essential Kitchen Dimensions You Need to Know
Bookmark this super-helpful beginner’s guide to the basics of planning a kitchen
A basic understanding of the key dimensions, such as the worktop height and appliance width, is a great foundation for your kitchen project. Coupled with the dimensions of the space available for your units, you can begin to make sense of your options and start pinning down the layout that works best for you.
You’ll then be in a position to decide on whether to go for a custom-built or ready-made kitchen. That choice alone merits discussion separately, but suffice it to say that your kitchen research should include exploring the many fittings and gizmos that underpin the design of all kitchens. This will allow you to analyse the range of functional solutions available before you consider finishes and decorative touches.
You can rough out a plan for your new kitchen using a module of 60 x 60cm. This is the size of standard kitchen appliances, such as sinks, fridges, ovens and dishwashers.
In a big kitchen, you’ll be able to allow for larger appliances, such as American fridges and range cookers (both typically 90cm+ wide). A small kitchen may require you to scale back to options such as a 45cm-wide dishwasher, a 50cm sink or an under-counter (as opposed to tall) fridge. There’s also a wide range of drawer widths available. However, the 60cm module is a good place to start testing your options.
A standard worktop averages 90cm in height. This compares to a standard table height of 75cm. But 90cm is just an average. If you’re very tall and you opt for a custom-made kitchen (not necessarily a prohibitively expensive option), you can specify a worktop height more comfortable for your stature. In a small kitchen, a taller worktop could also afford the opportunity to add additional – and very useful – shallow drawers above the usual run of units.
Height-adjustable worktops are a great option for a multi-ability household, or where you wish to future-proof your home against any potential limited mobility.
The working side of an island unit (ie, the 60cm depth facing the kitchen) should match the height of the kitchen worktop, but the height of any extra depth can be varied to suit your needs. Here, for example, an additional slab of wood set higher than the main unit forms a breakfast bar. A height of 110cm works well for a breakfast bar, and can help to screen the kitchen from the rest of the room.
In other cases, it will be more restful and visually harmonious to have the base units and whole island at the same height.

A standard worktop is 60cm deep, following the dimensions of standard appliances. A working island will have a minimum depth of 60cm. Add an extra 30cm to accommodate either stools or shallow storage, or 60cm if you wish to accommodate both or if you prefer deep storage on either side.
The overall dimensions of your room will determine whether a 60cm, 90cm or 120cm island is best. The thickness of the worktop will generally be 4cm.
A minimum of 40cm is advisable between the top of the worktop and the lowest part of your overhead cupboards or shelving. Consider also the distance that will be required between your hob or cooker and an overhead extractor. In the case of gas, this will need to be 65cm, with 55cm advisable above electric or induction hobs.
Bear in mind that if you wish to create a straight line between your overhead cupboards and your extractor fan, you will need to adjust the height of your cupboards accordingly.
These will typically be 30cm deep, both to maximise access (deep cupboards would be difficult to access fully) and to prevent the cook from banging his or her head.
The height of the cupboards is down to personal taste. Full-height cupboards will avoid the dust-gathering ledge created by lower units, as well as creating storage for lesser-used objects at the top. In all cases, the shelving in your wall cupboards should be adjustable to maximise every centimetre of space.
This dimension is critical if your island will be plumbed for a sink or wired for a cooker, hob or other electrics.
A distance of 120cm was traditionally the norm here, based on the dimension required for two 60cm doors to open fully at the same time. However, given that drawers, not doors, are now most common in base units, I recommend an optimum distance of 100cm minimum here. This distance will allow you to take a heavy pot from worktop to island without taking a step. It also allows the island to remain visually connected to the main run of units.
Where space is at a premium, the distance can reduce to 90cm. Just be mindful of where you place the dishwasher, as the fully-lowered, traditional dishwasher door can create a trip hazard. This challenge can be overcome with a drawer dishwasher.
A minimum distance of 100cm will work here, meaning that a kitchen design comprising a straight run of units and a table will need to be 350cm wide. This allows for 100cm each side of a 90cm table and a worktop depth of 60cm.
A wider table would upset this balance, but could be accommodated by substituting one row of chairs for a bench placed along the wall.
Drawers are generally agreed to be the optimum way of accessing storage below the worktop. Shallow drawers, with a minimum height of 6cm clear internally, are useful for cutlery, rolls of clingfilm and tin foil, spices and other shallow objects.
Deeper drawers are good for pots and pans, and may also be used, with inserts, for crockery and a variety of other, large items. However, avoid drawers that are too deep, as they can become overly heavy when fully loaded, as well as being difficult to fill efficiently.
A good solution is to provide a shallow top drawer above two equally sized deeper drawers. Where the appearance of deeper drawers is required for aesthetic reasons, inner drawers can enhance the functionality without compromising on appearance.
A kitchen needs to provide storage for numerous objects of all shapes and sizes, so think creatively about how every centimetre can be used.
