Cabinet Dimensions

People get confused when it comes to a cabinetry width, depth and especially height. There are two types of cabinetry: standard and custom. Custom cabinetry technically can be made any size. In this blog I want to talk about standard cabinetry dimensions.

Width: standard cabinet width starts with a 9” and can be as wide as 48” and it applies to base and wall cabinets. Size increases every 3”, i.e. 9”, 12”, 15” etc. Why can’t it be smaller or bigger? Smaller than 9” cabinets becomes unpractical and with a limited usage. It’s good as a spice cabinet with a pull out function or for sliding in cooking pans. Also there is no need to have a cabinet bigger than 48” wide. It’s a huge cabinet with a two 24” doors. Kitchen sink cabinets are 33” or 36” (sometimes 42”) width. Most common width is 36”, but it all depends on layout and the size of a sink bowl you choose. Also there are corner base cabinets called “Lazy Susan”, those are 36”x36” and upper one is 24”x24”.

Depth: standard kitchen base cabinets are 24” deep and uppers (wall cabinets) are 12”, 15”, 18” and 24”. If it’s a simple kitchen model most likely people will use 12” wall cabinets, but if it has some elevation changes there might be 15”, 18” or even 24” deep cabinets. Standard bathroom vanity is 21” deep, but depending on the size of the bathroom and design it might be 18” or 24”.

Height: kitchen base cabinets are 34 ½” height. Standard wall cabinets start from 30” and go every 3” up to 42” height. But wall cabinets also can have 15”, 18”, 21” or 24” height. Those cabinets usually are used as a hood/microwave cabinet, above the fridge or for customizing cabinet elevations. Why there are no upper standard cabinets higher than 42”? Side panels are 96” height which means 54”+42”=96”. 54” is the height where the bottom of the upper cabinets starts. 42” is the tallest upper cabinet. Vanities are 30” height. Now people like to put higher vanities and it became very popular lately. Base cabinets for a bar height are 40 ½”.
