Kitchen countertop heights are an important consideration in ergonomic design, as this height and dimension will directly impact comfort, efficiency, and overall user experience. We don’t always think a lot about countertop and table top and bar top heights, we just live with them in most cases. When in the process of designing a kitchen or designing a kitchen retro fit, you actually have a choice, and for particularly short or particularly tall users, the decision can really impact the ergonomics and feel of comfort in using and working in a kitchen and dining area. The standard countertop height of 36 inches has become a widely accepted norm in the industry, here in the USA, as it fits well and accommodates the average height and reach of most adults.
The 36-inch countertop height is particularly well-suited for individuals within the typical height range, which encompasses a significant portion of the adult population. According to studies, approximately 68% of men fall within the range of 5 feet 6 inches to 6 feet 1 inch, while the median height for women is around 5 feet 4 inches**. By designing countertops at this standard height, kitchen spaces can cater to the ergonomic needs of the majority, minimizing strain and discomfort during food preparation and other kitchen tasks.
It’s important to note that adult human height follows a normal distribution curve, with the majority of individuals clustered around the mean or average height, and fewer outliers at the extreme ends of the curve. While the 36-inch countertop height may not be ideal for those significantly taller or shorter than the average, it provides a comfortable working surface for the vast majority of users.
In contrast, bar tops and table tops often have different height requirements, catering to specific purposes and ergonomic considerations. Bar tops, typically ranging from 42 to 48 inches in height, are designed for standing or seated use, facilitating a more casual and social atmosphere. These taller surfaces accommodate stools or bar chairs, creating a comfortable seating arrangement for dining, entertaining, or enjoying drinks and appetizers.
Table tops, on the other hand, are generally lower, ranging from 28 to 30 inches in height, to accommodate chairs or benches for seated dining or work purposes. This height allows individuals to comfortably sit with their legs beneath the table, reducing strain on the back and promoting proper posture during meals or activities such as studying or working on a laptop.
When designing kitchen spaces, it’s important to consider these ergonomic needs of the intended users, as well as the specific functions and purposes of different surfaces. By taking into account the distribution of adult heights and adhering to established industry standards, designers can create kitchen environments that prioritize comfort, efficiency, and overall user satisfaction, minimizing the risk of strain or discomfort over time. Particularly, in retrofit type scenarios, these dimensions and changing of heights might have other implications and/or impact the location or extent of work required in the construction. For example, most kitchen rough-ins are set with the drain and water supply around 12 to 18 inches above the floor but this isn’t standardized and the existing rough-in may differ slightly and or to the point that it may need to be modified when countertop heights are changed. Homeowners should also think about their plans for resale. If you plan to live in your home for the rest of your life, then it’s probably a good idea to design it to fit you best, even if it doesn’t fit the average person as well as it will fit you. Our company has built kitchens that had countertops that were 2 inches high above standard for particularly tall clients who were in their retirement years. They particularly plan to live in that Capital Hill home for the rest of their lives, to age in place. So they were planning on being there for the rest of their life and had no intentions of ever selling that house. Young homeowners might take a pragmatically different perspective in this consideration though.
We might suggest considering the height of stools first for bar tops. This may seems a little bit reverse or possibly like a chicken and egg quandary where it’s not necessarily clear which one should precede the other but it sometimes can make it easier to find the perfect bar stool first and then design the countertop height, both with considerations of the surroundings and with the height of the bar stool.
When designing a bar area with bar stools, the main dimension to consider is the space between the top of the stool seat and the underside of the bar top. Good planning can factor sufficient space for movement and comfort of your legs but too much space will put the bar in an uncomfortable comparative position. A common guideline is to allow 10 to 13 inches of clearance between the seat top and bar underside to accommodate legroom and facilitate entry and exit from the stools. This clearance dimension often pairs with a bar top height of around 42 to 44 inches from the floor level and a standard bar stool seat height ranging from 28 to 34 inches. If you (and friends and family) are generally relatively thin and on the smaller size, consider the lower range of those dimensions and if you’re tall and big then consider the upper range of those dimensions.
The bar top itself typically features an overhang of 8 to 12 inches from the edge of the bar cabinets or supports beneath. This overhang allows users to tuck their legs comfortably underneath the bar top without obstruction. A very common configuration incorporates a 12-inch overhang bar top installed at 42 inches above the floor, complemented by 30-inch bar stools, resulting in the desired 12 inches of legroom between the seat and bar underside. While these dimensions suit most average-height adults, some flexibility may be required to optimize ergonomics for taller individuals who may need extra legroom or shorter users who prefer a lower bar top height. Additionally, local building codes frequently mandate minimum clearance requirements under bar tops and counters to ensure accessibility standards are met.
