What Are the Standard Kitchen Worktop Dimensions in the UK?
Quick Answer
600mm deep, 900mm high, stocked in 3.0m, 3.6m and 4.1m lengths
Laminate is usually 28–40mm thick, solid wood 27–40mm, and stone or quartz 20–30mm. A 20–30mm front overhang is standard; breakfast bars step up to 900mm depth with more overhang for knee room.
Worked Example: Slabs and Joints
UK laminate worktops are stocked at 3.0m, 3.6m and 4.1m lengths (Worktop Express, Howdens and Wickes all list these three). A run only needs one slab if it fits within the 3.6m stock length; anything longer needs a joint.
- A 3.2m straight run at the standard 600mmdepth covers 3.2 × 0.6 = 1.92m² of worktop and needs just one 3.6m slab, no joint, because 3.2m is under the 3.6m stock length.
- A 4.2m run exceeds the 3.6m stock length, so it needs two slabsjoined with a worktop bolt and colour-matched sealant, typically at a mason’s mitre if the run turns a corner.
Standard Dimensions at a Glance
| Dimension | Standard figure | Notes |
|---|---|---|
| Depth (base units) | 600mm | Sits on a 570mm base unit with a 20–30mm front overhang |
| Height (floor to top surface) | 900mm | The most common ergonomic working height; can vary 850–950mm by user height |
| Standard slab lengths | 3.0m, 3.6m, 4.1m | Laminate stock lengths; stone and quartz are templated and cut to size |
Thickness by Material
- Laminate: 28–40mm, with 38–40mm the most common and 28mm a slimmer, more affordable option
- Solid wood: 27–40mm, with 40mm the classic “butcher’s block” style
- Quartz and granite: 20–30mm, with 30mm the traditional granite thickness and 20mm popular for a slimmer, modern look
- Solid surface: around 12mm, usually bonded over a substrate for stiffness
Overhang and Upstands
- Base unit overhang: 20–30mm at the front, directing spills clear of cabinet doors
- Breakfast bar or island overhang: roughly 200–300mm for comfortable knee room under stools; some guides recommend a minimum of 300mm
- Upstand height: 100mm is standard where an upstand runs along the wall instead of a full splashback
How to Measure for a New Worktop
Measure each run separately along the wall at worktop height, from wall to wall or corner to corner, and note where the sink, hob and any appliances sit. For an L-shape or U-shape kitchen, measure both walls into the corner rather than across it. Add the 20–30mm front overhang if you are checking clearance against door and drawer fronts, and leave scribing allowance where a run meets an uneven wall. Stone and quartz worktops are templated on site after the units are fitted, so exact final dimensions are taken by the fabricator rather than measured by hand.
Important Notes
- These are the common, widely stocked figures from UK worktop suppliers, not a single universal spec: always check the exact range of your chosen supplier before ordering
- Stone, quartz and solid surface worktops are usually made to measure, so the stock-length figures above apply to laminate and solid wood
- Deeper 650mm and 900mm worktops are available for breakfast bars and island units
