Hospital Sizes: Understanding The Standard Square Footage

The size of a hospital varies depending on its location and the number of beds it staffs. For example, hospitals in the Northeast region of the US tend to have the largest average square footage at 602,691.24 sq. ft., while hospitals in the Southeast and Midwest follow closely with average square footages of 339,627.53 sq. ft. and 333,349.21 sq. ft., respectively. In terms of the number of beds, hospitals with 100 or fewer beds average under 200,000 square feet, while hospitals with more than 250 beds can average 1.2 million square feet. Additionally, the height of each floor in a hospital typically ranges from 3 to 4 meters, depending on the hospital's design and modernity.

Hospitals with 100 beds or fewer: 200,000 sq. ft

Hospitals have become larger over the years, and the average hospital size varies across different regions. For instance, hospitals in the Northeast region of the US tend to be larger, with an average size of 602,691.24 sq. ft. This is due to the presence of major teaching hospitals, specialized medical centres, and advanced healthcare infrastructure in cities like New York, Boston, and Philadelphia.

In contrast, hospitals with 100 beds or fewer typically have a smaller footprint. According to one source, a 100-bed hospital with 4-5 specialties and 1-2 super specialties should have around 600 sq. ft. per bed, which equates to a total of 60,000 sq. ft. of buildup area. This type of hospital would require approximately 30,000 sq. ft. of land, assuming a Floor Area Ratio (FAR) of 2. The FAR is a multiplier that defines how much can be built on a given plot of land and typically ranges from 1.5 to 3.

Another source suggests that hospitals built over 30 years ago had, on average, 1,300 to 1,600 Building Gross Square Feet (BGSF) per bed. However, today's hospitals often range from 2,200 to 2,800 BGSF per bed. This increase in space per bed can be attributed to various factors, including the transition from multi-bed inpatient rooms to private rooms, which offer benefits such as improved patient privacy, infection control, and patient preference.

The size of private inpatient rooms typically falls between 260 and 320 net square feet (NSF). These rooms include private toilet and shower facilities, distinct zones for patients, caregivers, and family members, and ample space for mobile technology. Additionally, the size of exam rooms has increased to 120 NSF to accommodate accessibility needs and the requirements of caregivers and patients.

While the square footage per bed has increased in modern hospitals, the overall size of a 100-bed hospital would still be significantly smaller than the average hospital sizes reported for various regions in the US. Therefore, hospitals with 100 beds or fewer can be expected to utilise space more efficiently while providing essential healthcare services to their communities.

Hospitals with 100-250 beds: 446,000 sq. ft

The size of a hospital is determined by several factors, such as the number of beds, annual patient discharges, operating rooms, and average daily census. Hospitals with 100-250 beds typically have an average size of 446,000 square feet, which is slightly above the national average. This equates to roughly 60,269.12 square feet or 5,598.34 square meters per bed.

To put this into context, the average Walmart store in the United States is around 104,000 square feet, so a hospital in this size range would be equivalent to approximately four Walmart stores. Another way to visualize it is that an NFL football field, excluding the end zones, is 57,600 square feet, so this hospital size would be roughly equivalent to eight football fields.

The size of hospitals can vary significantly depending on their location and the demographics of the region they serve. For example, hospitals in the Northeast region of the United States tend to be larger, with an average square footage of 602,691.24 sq. ft. This is due to the presence of major teaching hospitals, specialized medical centers, and advanced healthcare infrastructure in cities such as New York, Boston, and Philadelphia.

In contrast, hospitals in the Midwest and Southeast regions have a more moderate average square footage of around 330,000 to 340,000 sq. ft. These regions have a mix of large hospitals in urban areas and smaller regional centers serving rural populations. The Southeast's population growth has also led to the development of larger medical facilities to meet the region's healthcare needs. Therefore, while the average hospital with 100-250 beds may be around 446,000 sq. ft., the specific size can vary based on regional factors and the healthcare infrastructure's unique requirements.

Hospitals with 250+ beds: 1.2 million sq. ft

The size of a hospital is determined by several factors, including the number of beds, annual patient discharges, the number of operating rooms, and the average daily census. Hospitals with 250 or more beds have an average size of 1.2 million square feet. This figure is sourced from the Definitive Healthcare HospitalView product, which provides data on hospital facility square footage by aggregating information from over 5,800 hospitals.

The size of hospitals can vary significantly depending on their location and the specific healthcare needs of the region they serve. For example, hospitals in the Northeast region of the United States tend to have the largest average square footage, with specialized medical centers and advanced healthcare infrastructure in cities like New York, Boston, and Philadelphia. On the other hand, hospitals in the Southwest may have smaller average square footage due to the mix of urban and rural areas.

Children's hospitals, due to the specialized nature of pediatric care, have the largest average square footage of any hospital type, with 861,268.51 square feet on average. This allows for both medical facilities and child-friendly environments. In contrast, religious non-medical health care institutions are the smallest, with an average of 32,126.64 square feet, reflecting their more limited range of services.

The largest hospital in the United States in terms of facility size is Creedmoor Psychiatric Hospital, with nearly 9.5 million square feet. However, it has only 349 staffed beds, indicating that psychiatric hospitals tend to have larger room sizes to accommodate the unique needs of long-term mental health patients. By comparison, the largest hospital by the number of beds is AdventHealth Orlando, with 2,247 staffed beds, but it has a lower square footage.

In summary, hospitals with 250 or more beds average around 1.2 million square feet in size. However, this can vary based on regional demographics, healthcare infrastructure, and access to specialized care. Hospital size is an important consideration for real estate and construction companies when planning new facilities to ensure they meet the diverse needs of their patient populations.

Average floor height: 3-4 meters

The height of each floor in a hospital depends on various factors, including the hospital's location, design, modernity, and available construction space. On average, each floor in a hospital is around 3 to 4 meters high.

In the United States, the average height of each floor in a hospital is 12 feet, which is approximately 3.66 meters. This height includes the vertical personal space, which is often around 3 meters, and additional space for ductwork, electrical wiring, and similar interstitial space. This extra space allows for future functionality changes, making it easier to adapt than if the space were tightly packed.

The height of each floor can vary depending on the hospital's design and modernity. For example, hospitals built in the last 20 years are likely to have taller floors, providing more space for infrastructure, than those constructed 40 to 60 years ago. Additionally, the upfront construction cost can be a factor, as newer hospitals with more modern amenities may have floors that are 4 meters high, while older or less financially endowed hospitals may have floors that are 3 meters high.

The average height of hospital floors can also vary by region. For instance, hospitals in the Northeast region of the United States tend to have larger square footage and may have taller floors due to the presence of major teaching hospitals, specialized medical centers, and advanced healthcare infrastructure in cities such as New York, Boston, and Philadelphia. In contrast, hospitals in other regions, such as the Midwest, may have more moderate square footage and floor heights, serving a balance between large urban hospitals and smaller regional centers catering to rural areas.

Northeast region hospitals: 602,691 sq. ft

Hospitals in the Northeast region of the United States are, on average, the country's largest. With a footprint of 602,691 square feet, these hospitals are nearly double the national average of 354,000 square feet. The Northeast region's hospitals are generally larger due to a higher concentration of major teaching hospitals, specialized medical centres, and advanced healthcare infrastructure in cities such as New York, Boston, and Philadelphia.

The size of a hospital can vary depending on several factors, including the number of beds, the range of specialities offered, and the patient-paying capacity. Hospitals with 100 or fewer beds average under 200,000 square feet, while those with 101 to 250 beds average 446,000 square feet. Hospitals with more than 250 beds have an average size of 1.2 million square feet. The number of beds is not the only factor influencing the size of a hospital, as the range of specialities offered can also impact the required space. For example, a dialysis ward requires a dedicated space for dialysis treatment, as well as a reprocessing area and other specialised equipment.

The patient-paying capacity is another factor that affects hospital size. Hospitals catering to very high-paying patients, such as those charging 1 Lakh per day for an ICU patient, can have up to 1200 square feet of build-up space per bed. In contrast, a low-cost hospital with 6-12 bed wards will have more beds in a given space. Private rooms also influence the overall size of a hospital, as they require more space than multi-bed inpatient rooms. The current norm is for private rooms with private toilet and shower facilities, distinct zones for patients, caregivers, and family, and space for mobile technology. The transition to private rooms is driven by factors such as patient privacy, infection control, and patient preference.

The Northeast region's hospitals stand out not only for their size but also for their advanced healthcare infrastructure. The average square footage of hospitals in this region reflects the presence of major teaching hospitals and specialised medical centres. The Northeast's healthcare infrastructure, including the size of its hospitals, is shaped by factors such as population density and access to specialised care. The vast geographic area and distribution of hospitals in other regions, such as the West and Southwest, contribute to variations in hospital sizes within those regions.
