You may have noticed when you walk into a kitchen, the cabinets don’t typically go all the way up to the ceiling. Your gap may be utilized for extra storage or decoration, or it just could be collecting dust. Though the decision ultimately comes down to personal preference, there are some specific reasons why designers or contractors may recommend keeping the open space. 

1. Access: Your kitchen cabinets store all your kitchen necessities like plates, cups, pots and pans. You likely need access to these items daily, but if they are stored all the way to the ceiling, you wouldn’t be able to reach! It would be incredibly inconvenient to need a stool, chair, or ladder every time you need a cup. 
2. Aesthetics: When designing a kitchen, visual aesthetics plays a significant role. A gap between the cabinetry and ceiling can create an appealing, balanced look. The space also allows for other design features like crown molding. Open shelving can also be decorated and used to enhance a space. By displaying decor, plants, and other visual components, you can add personality and customizations to a space. 
3. Ventilation: Some homes have necessary systems in their ceiling. If the cabinets were to touch the ceiling, there could be ventilation issues that would cause a hazard. Whether it is vents, ducts, or other utilities in the ceiling, the clearance allows for your family to be safe and your home to be properly ventilated. 
4. Money: Like many aspects of life, expense plays a factor in this decision. Standard sized cabinets are already a costly investment, so adding custom dimensions can cause an already high price to skyrocket. Because not all kitchens and ceilings are the same, the custom cabinets that reach the ceiling would have to be made when ordered. Allowing for the gap, lets builders prebuild the cabinets with standard dimensions. 

Kitchen cabinets should be functional, efficient, and accessible, and the space between your cabinets and ceiling can vary based on kitchen layout, individual design, and functional requirements. Next time you step into the kitchen, you can eye the gap knowing that there has been thought into its existence.
