Standard Kitchen Cabinet Sizes

If you want to buy your cabinet, first thing that you need to know is how to read the label. Cabinet manufacturers use these codes for standard kitchen cabinet sizes and styles. You can mark each cabinet this way in your design. The common code for a cabinet is arranged as follow: the type of the cabinet with capital letters, and then followed by Width-Height-Depth’s (W-H-D) size. A cabinet with W2436 can be described as follows: the code W means Wall, the number 24 is the width and the number 36 is the height. A wall cabinet usually has 12” as the standard depth.
