Standard Dimensions For Australian Kitchens

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.

Kickboard Height

The preferred kickboard height is 150mm. The height range can be between 100mm to 200mm.

Benchtop or Working Height

This is the distance between the floor and the top of the benchtop. The recommended standard benchtop height is 900 +/- 20mm. The working height can be within the range of 850mm to 1050mm. N.B You must be mindful when working with benchtop heights around the 1050mm 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.

Benchtop Depth

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 600mm deep. (Older kitchens can have a standard benchtop depth of 450mm).

Standard benchtop depths for breakfast bars;

  • 300mm
  • 450mm
  • 600mm

Standard benchtop depths for kitchen islands;

  • 600mm
  • 750mm
  • 900mm
  • 1200mm

The benchtop edge overhang is usually 20mm from the front face (door / drawer) of the floor cabinet.

Floor Cabinets

The preferred height for floor units is 720 +1/-4mm (not including kickboard). Floor unit depth ideally should not exceed 600mm (handles excluded). The preferred floor unit depth is 580mm inclusive of door thickness.

Standard dimensions for stock or DIY base (floor) cabinets are generally 720mm high by 560mm deep (without the door). Floor cabinet widths generally increase by 150mm increments. The maximum door width for a base cabinet is 600mm. This is due to the door weight loading on the door hinges.

Standard dimensions for stock / DIY floor cabinets

  • 300mm wide x 720mm high x 560mm deep (1 door)
  • 450mm wide x 720mm high x 560mm deep (1 door)
  • 600mm wide x 720mm high x 560mm deep (1 door or 2 doors)
  • 750mm wide x 720mm high x 560mm deep (2 doors)
  • 900mm wide x 720mm high x 560mm deep (2 doors)
  • 1050mm wide x 720mm high x 560mm deep (2 doors)
  • 1200mm wide x 720mm high x 560mm deep (2 doors)

Wall Cabinets

The preferred height for wall units is 720 +1/-4mm. Wall unit depth ideally should not exceed 350mm (handles excluded). There should be 280mm minimum clear space from back of cupboard. I personally prefer a 300mm minimum clear space so you can store large diameter plates with ease.

Standard dimensions for stock or DIY wall cabinets are generally 720mm high by 300mm deep (without the door). As for the floor cabinets, wall cabinet widths generally increase by 150mm increments.

Standard dimensions for stock / DIY wall cabinets

  • 300mm wide x 720mm high x 300mm deep (1 door)
  • 450mm wide x 720mm high x 300mm deep (1 door)
  • 600mm wide x 720mm high x 300mm deep (1 door or 2 doors)
  • 750mm wide x 720mm high x 300mm deep (2 doors)
  • 900mm wide x 720mm high x 300mm deep (2 doors)
  • 1050mm wide x 720mm high x 300mm deep (2 doors)
  • 1200mm wide x 720mm high x 300mm deep (2 doors)

Tall Cabinets

There is no preferred height for tall units. Having said that, you can easily determine the ideal height by adding up the floor unit height, benchtop thickness, splashback and wall unit heights (720mm + 33mm + 450mm + 720mm = 1923 +1/-4mm). I personally prefer a tall unit depth of 600 to 610mm inclusive of door thickness.

Standard Door Sizes

It is easy to work out the correct standard door width and height for any (frameless) kitchen cabinet. Simply subtract 3mm from the cabinet height and 3mm from the cabinet width. For pair doors subtract 6mm from the cabinet width.

For example:

If a floor cabinet was 720mm high x 450mm wide (1 door) the correct door size would be 717mm high x 447mm wide.

If a wall cabinet was 600mm high by 1000mm wide (2 doors) the correct door size would be 597mm high x 497mm wide.

Overall Kitchen Height

Is determined by adding up the kickboard height, floor unit height, benchtop thickness, splashback height and wall unit height (150mm + 720mm + 33mm + 450mm + 720mm = 2073 +1/-4mm).

Splashback Height (under wall unit)

The minimum splashback height is 450mm. If you have a wall unit over a sink then there should be a minimum of 600mm 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 600mm.

Rangehood Height Above Gas Cooktop

The minimum height of the rangehood above a gas hob is 650mm. Most manufacturers recommend a minimum height of 700-750mm.

Oven / Wall Oven Dimensions

The standard under bench oven size is 600mm wide x 600mm high. The under bench oven can be used as a wall oven (and vice-versa). Pizza oven types are usually 900mm wide x 600mm high.

Wall oven dimensions are normally 600mm wide x 600mm high or 600mm wide x 900mm high. Occasionally wall ovens can be 900mm wide x 600mm high (pizza ovens).

Free-standing Oven Dimensions

Standard sizes of kitchen appliances such as free standing ovens or ranges (be they gas or electric) come in five standard widths.

  • 540mm
  • 600mm
  • 750mm
  • 900mm
  • 1200mm

These are nominal dimensions (i.e not exact but very close to) as different appliance manufacturers have varying standards.
