I have just got a new house I want to put up an extra kitchen cabinet to create space. You can never have enough space. So I have done research on kitchen doors blindly assuming I could get a cabinet easily. I have measured the existing cabinets - height 730mm and depth 310mm. So I look on the internet and it seems that the standard height and width are 720mm and depth 300mm. I can't believe these are non standard cabinets. I have checked my measurements carefully. Am I missing something? Is there some special thing you have to take into account? I have ignored the doors which are not framed. Any advice welcome.
