Is your existing benchtop height in your kitchen too low? What height should it really be? This is a summary of preferred dimensions which are standard for most kitchens built in Australia today.
The preferred kickboard height is 150 mm. The height range can be between 100 mm to 200 mm. The kickboard depth (from the front of the floor cabinet carcass excluding the door) is 50 mm. (Fig 1)
Fig.1 – Whilst the kickboard can range in height between 100 to 200 mm, the preferred height is 150 mm
Benchtop or working height
This is the distance between the floor and the top of the benchtop. The recommended standard benchtop height is 900 mm +/- 20 mm. The working height can be within the range of 850 mm to 1050 mm. (Fig. 2)
A lot of people confuse benchtop width with the depth. Benchtops can be any width (and that depends on the material used for the benchtop) however, the most common depth for benchtops in Australia today is 600 mm deep. (Older kitchens usually have a standard benchtop depth of 450 mm).

The benchtop edge overhang is 20mm from the front face (door / drawer) of the floor cabinet.
Standard benchtop thickness
The most common benchtop material is laminate and it’s standard thickness is 33 mm. It is made with a 32 mm thick particle board or MDF substrate and a 0.8 mm thick piece of laminate glued to it.
Of course the thickness of the benchtop will vary as it is dependent on the type of material used. Other benchtop materials include granite, limestone or engineered stones such as Caesarstone. They are usually 20 mm thick slabs and for thicker tops, the edge is built up by another 20 mm.
Laminate benchtop thickness = 33 mm
Granite / limestone thickness = 20 mm (or 40 mm with built up edge)
Caesarstone (engineered stone) = 20 mm (or 40 mm with built up edge)
You must be mindful when working with benchtop heights around the 1050 mm height range. Appliances such as dishwashers will end up having a large gap between itself and the benchtop. You could consider raising the height of the dishwasher by putting a drawer underneath it or by putting a drawer above it.
Fig. 2 – The standard benchtop height is 900 mm. This can vary by +/- 20 mm
The standard height for floor cabinets is 720 +1/-4 mm (not including the kickboard). Floor cabinet depth ideally should not exceed 600 mm (handles excluded). The standard floor cabinet depth is 580 mm inclusive of door thickness.
Standard dimensions for stock or DIY base (floor) cabinets are 720 mm high by 560 mm deep (without the door). Floor cabinet widths generally increase by 150 mm increments (Fig. 3). The maximum door width for a base cabinet is 600 mm. This is due to the door weight loading on the door hinges.
Standard dimensions for stock / DIY floor cabinets
Dimensions shown below do not include the door
300 mm wide x 720 mm high x 560 mm deep (1 door)
450 mm wide x 720 mm high x 560 mm deep (1 door)
600 mm wide x 720 mm high x 560 mm deep (1 door or 2 doors)
750 mm wide x 720 mm high x 560 mm deep (2 doors)
900 mm wide x 720 mm high x 560 mm deep (2 doors)
1050 mm wide x 720 mm high x 560 mm deep (2 doors)
1200 mm wide x 720 mm high x 560 mm deep (2 doors)
Fig. 3 – Standard floor cabinet widths are commonly sized in 150 mm increments
The standard height for wall cabinets is 720 +1/-4 mm. Wall cabinet depth ideally should not exceed 350 mm (handles excluded). There should be 280 mm minimum clear space from the back of the cupboard. I personally prefer a 300 mm minimum clear space so you can store large diameter plates with ease.
Standard dimensions for stock or DIY wall cabinets are 720 mm high by 300 mm deep (without the door). As for the floor cabinets, wall cabinet widths generally increase by 150 mm increments (Fig 4).

1200 mm wide x 720 mm high x 300 mm deep (2 doors)

Standard Tall Cabinet Height
The standard height for tall cabinets (pantry, wall oven etc) is 2073mm +/- 20mm. (Fig. 5) The height is determined by adding up the floor cabinet height, benchtop thickness, splashback height and wall cabinet height (720 mm + 33 mm + 600 mm + 720 mm = 2073 mm +/- 20 mm). The standard tall cabinet depth is 600 mm.
Standard Door Sizes
It is easy to work out the correct standard door width and height for any (frameless) kitchen cabinet. Simply subtract 3 mm from the cabinet height and 3 mm from the cabinet width. For 2 door cabinets subtract 6 mm from the cabinet width and divide the result by 2.
Door width = cabinet width – 3 mm
Door height = cabinet height – 3 mm
If a floor cabinet was 720 mm high x 450 mm wide (1 door) the correct door size would be 717 mm high x 447 mm wide.
If a wall cabinet was 600 mm high by 1000 mm wide (2 doors) the correct door size would be 597 mm high x 497 mm wide.
Standard Kitchen Height
The standard kitchen height is 2223mm +/- 20mm. (Fig. 5) The height is determined by adding up the kickboard height, floor unit height, benchtop thickness, splashback height and wall unit height (150 mm + 720 mm + 33 mm + 600 mm + 720 mm = 2223 mm +/- 20 mm).
Fig. 5 – The standard kitchen height can easily be worked out by adding up the kickboard, floor cabinet, benchtop, splashback and wall cabinet heights
Splashback Height (under wall unit)
The minimum splashback height is 450 mm. If you have a wall unit over a sink then there should be a minimum of 600 mm splashback height between the top of the sink and the bottom of the wall unit.
Rangehood Height Above Electric Cooktop
The minimum height of the rangehood above an electric cooktop (coil, ceramic, Ceran glass and magnetic induction) is 600 mm.
Rangehood Height Above Gas Cooktop
The minimum height of the rangehood above a gas hob is 650 mm. Most manufacturers recommend a minimum height of 700 – 750 mm.
Oven / Wall Oven Dimensions
The standard under bench oven size is 600 mm wide x 600 mm high. The under bench oven can be used as a wall oven (and vice-versa). Pizza oven types are usually 900 mm wide x 600 mm high.
Wall oven dimensions are normally 600 mm wide x 600 mm high or 600 mm wide x 900 mm high. Occasionally wall ovens can be 900 mm wide x 600 mm high (e.g pizza ovens).
Freestanding Oven Dimensions
Standard sizes of kitchen appliances such as free standing ovens or ranges (be they gas or electric) come in five standard widths.
These are nominal dimensions (i.e not exact but very close to) as different appliance manufacturers have varying standards.
Having standard dimensions certainly makes life easier for kitchen designers as it provides a solid, workable framework to develop an efficient and safe design. However, there are other standards that are vitally important to understand when designing a kitchen. These standards are very important as they are issued by a professional or governmental regulatory authority and certain rules must be adhered to.
