In this metric data post we will be looking at standard kitchen layouts and sizes. To make it more useful, we have put together a reference PDF with all of the sizes that you can download for free. On top of that you can get all of the CAD drawings that are featured in this post from our shop for a small fee.

In this post we explore standard kitchen information for units, appliances, layouts and more.

The sizes below are suggestions, and of course, kitchens come in many different sizes – but this is a good starting point and guide. It is especially useful if you have the cad drawings to drag and drop directly into your floor plans.

Standard kitchen sink sizes

Small kitchen sink: 500mm depth x 600mm width

Mid kitchen sink: 500mm depth x 1000mm width

Large kitchen sink: 500mm depth x 1200mm width

Kitchen Design Rules of thumb

There are some fundamental design principles when it comes to planning your kitchen that should be considered. These rules of thumb should help you avoid potential awkward spaces, and poor functionality.

Rule 1 – Kitchen door clearance

Ensure there is at least 400mm clearance between a kitchen door and the nearest units. This essentially means allowing for 1200mm between the units and the wall with the door.

If you are planning a narrow galley style kitchen, and the room is less than 1800mm wide, you cannot comfortably use a standard 600mm deep unit. You may need to use bespoke (however this would affect appliances) – or reconsider your design.

Rule 2 – Distance between units

Allow a minimum 1200mm clearance between runs of units. Most doors open up to around 600mm, i.e. dishwasher, oven door, unit door so a minimum of 1200mm will allow people to pass when then doors are open.

A distance of 1500mm between units will allow two people to pass with ease when the doors are closed.

Rule 3 – Work triangle

Rule 4 – Clearance between worktop and wall mounted cabinet

Rule 5 – Door Interference

Rule 6 – Distance behind seating

Ensure you provide enough space behind a seated diner to allow traffic to pass.

The minimum clearance from the table or counter to any wall or other obstruction behind the seating area is 800mm.

If someone is to walk past, a distance of 1100mm should be provided. For a wheelchair to comfortably move past the seated diner a distance of 1500mm should be provided.

Rule 7 – Food preparation and work area

Rule 8 – Cooking surface

Rule 9 – Traffic

Rule 10 – Don’t break up the workspace

Rule 11 – Place the sink in the centre

Rule 12 – Dishwashers

Rule 13 – Oven set down space

Rule 14 – Fridge set down space

Rule 15 – Fire

Rule 16 – Regulations
