Typical Kitchen Worktop Sizes: Standard Depth and Height in the UK

Replacing a kitchen, designing a new one, or just measuring up before buying a worktop. Either way, the standard sizes matter. Get them wrong and the cabinets don't line up, the appliances don't fit, or your back aches every time you chop an onion.
We're a Kettering-based team specialising in kitchen fitting in Northamptonshire. Here's a quick, no-fluff guide to typical UK kitchen worktop sizes, what's considered standard, and when to deviate from the default.
How deep are kitchen worktops?
Standard UK kitchen worktops are 600mm deep. This matches the depth of standard base units, with the worktop sitting flush at the back wall and slightly overhanging at the front. Slimline kitchens may use 500mm or 550mm worktops, while modern designs and islands often go to 650mm, 700mm or wider.
The 600mm standard exists because it matches the depth of UK kitchen base units (carcasses), which are themselves built to take standard 600mm-wide appliances like dishwashers and ovens. A few common worktop depth options:
500mm or 550mm. Slimline. Used in narrow galley kitchens, utility rooms, or where space is tight against a corridor or door.
600mm. The UK standard. Matches standard base units. Fits all major appliances (dishwashers, washing machines, ovens) which are designed around 600mm cabinet depths.
650mm. A modest upgrade. Gives slightly more workspace and lets you push wall sockets back behind small appliances on the counter.
700mm. Becoming popular in higher-end kitchens. Useful in large family kitchens where the worktop sees heavy use.
900mm or more. Typical for islands and breakfast bars. Wider than standard so the worktop can serve as both prep and casual dining space.
The trade-off with going deeper than 600mm: tall appliances (built-in ovens, fridges, freezers) come in 600mm depth as standard, so a deeper worktop creates a step in the cabinet line that has to be filled with packers or extended cabinet ends.
How high is a kitchen worktop?
The standard UK kitchen worktop height is 900mm from the finished floor to the top of the worktop. This is a comfortable working height for most adults of average height. Worktops can be raised to 920mm or 950mm for taller users, or lowered to 850 to 880mm for shorter users or accessible kitchens, by adjusting the plinth or cabinet height.
The 900mm standard breaks down roughly as:
150mm plinth (the kick board at the base)
720mm cabinet carcass
30mm worktop thickness
Most UK kitchen base units come in this configuration. The plinth height is the easiest dimension to adjust if you need a non-standard worktop height.
What affects the ideal height for the user:
User height. A general rule is that the worktop should sit about 100 to 150mm below the user's elbow when standing relaxed. For a 1.7m adult, that's roughly 900mm. For a 1.85m adult, closer to 950mm.
Primary cook. If one person does most of the cooking, design the height around them rather than splitting the difference between household members.
Type of cooking. Heavy chopping, kneading and rolling are easier on a slightly lower worktop. Boiling, frying and assembling are easier on a slightly higher one. Most kitchens compromise at standard height.
Accessibility. Wheelchair-accessible kitchens typically use 760 to 865mm worktops, with knee clearance underneath. This is a specific design exercise rather than a minor adjustment.
Some kitchen designs use mixed-height worktops, with a hob run set slightly lower than a prep run for ergonomic reasons. This works but adds cost and tends to look less seamless than a single consistent height.
Worktop thickness: a quick note
Worktop thickness varies by material:
Laminate: typically 28mm or 38mm
Solid wood: typically 27mm or 40mm
Granite and quartz: typically 20mm or 30mm
Composite stone: typically 12mm, 20mm or 30mm
Solid surface (Corian and similar): typically 12mm
Thickness affects the visual weight of the kitchen. Thinner worktops (12 to 20mm) look sleek and modern. Thicker ones (30 to 40mm) feel more traditional or substantial. The thickness sits on top of the cabinet, so a thicker worktop slightly raises the overall finished height.
