Hi Margaret, Kitchens have a lot of options so it's good to speak to your kitchen specialist about how you use your kitchen as drawer sizes tend to be influenced by type of item you are storing and which zone. DYNAMIC SPACE are Blum's ideas for practical kitchens, you can check out the zone planner, cabinet solutions and tips in our kitchen ideas section of our website. Think about the items you desire to store in your new kitchen in the following 5 zones and this will help you create a brief for your designer: Consumables, non-consumables, cleaning, preparation and cooking. Examples: 450 mm wide is a common width for a bench height rubbish bin solution with SERVO-DRIVE uno 600 mm is great width for a SPACE TOWER pantry 900 mm is a dream cutlery, utensil, plate or pot drawer Click for our NZ Kitchen Designer and Manufacturer Directory. All the best for your new kitchen. Regards, Sophie Blum NZ

Here is a layout indicating some minimum dimensions for usability. I would recommend you go larger especially if two people are often going to be using the space at one time. This also does not account for window space or furniture or storage.
