Most homes built in the previous several decades in the United States have ceilings at least this high, if not higher. The current norm for first-floor rooms in a typical new home is 9 feet. 8 feet is the norm for rooms on the second and upper levels. Ceiling fans are popular additions to bathrooms and bedrooms because they help reduce the amount of energy consumed by air conditioners during the summer and heating systems in winter.
The average height of male humans is 5 feet 10 inches (1.78 m), with a standard deviation of 2 inches (5 cm). The average height of female humans is 5 feet 4 inches (1.57 m), with a standard deviation of 1 inch (2.5 cm). Therefore, the average American human being is about 5 feet 7 inches (1.70 m) tall.
The average height of male mice is 16 inches (40 cm), with a standard deviation of 2 inches (5 cm). The average height of female mice is 14 inches (35 cm), with a standard deviation of 1 inch (2.5 cm). Therefore, the average American mouse is about 18 inches (45 cm) tall.
The average height of male monkeys is 28 inches (70 cm), with a standard deviation of 4 inches (10 cm). The average height of female monkeys is 24 inches (60 cm), with a standard deviation of 3 inches (7.5 cm).
In a new home, the average ceiling height is 9 feet, while the typical ceiling height varies by decade. The McMansion trend saw greater ceilings in the 1990s, and purchasers now are looking for modest yet functional places. For example, one family of four wants a house with a ceiling that's 12 feet high. They're not going for luxury or grandeur; they just want enough space to live comfortably.
The first thing you need to know about ceiling heights is that they can be as small as 3 feet or as large as 15 feet. Most homes fall in between these two numbers: 6 to 10 feet. Ceiling heights vary by room of the house. In general, rooms with smaller windows or doors tend to have lower ceilings because walls and floors provide support that ceilings don't. High-traffic areas such as living rooms and kitchens usually have higher ceilings than less used ones such as bedrooms. A family of four needs 2.5 feet of headroom on every side of the bed to sit up straight.
Ceilings also vary by style. Flat roofs are common in tropical climates because they avoid requiring construction of interior walls. However, if a household has pets or children, a peaked or domed roof may be preferred because it provides more protection against injury and damage.
On the first level of newer homes, nine-foot ceilings are common (and, sometimes, eight-foot ceilings on the second story). Many custom builders may presume that homeowners want nine-foot ceilings, but don't count on it. Most homeowners like having someplace to put their things - or not, if they're under five feet tall! The main reason for having such large rooms is so you can see everything that's going on during a home renovation or construction project.
New homes with less than 10 years old usually have 8-foot ceilings. Older homes with more than 100 years old often have 6-foot ceilings.
The height of your ceiling affects how many people your house can fit around a table for dining. If you need help fitting more guests at your table, check out our post about room sizing.
A principal bedroom is often rectangular or square in design, but can also be found in different configurations. Today's average ceiling height is 9 feet (2.7432 meters). Many of us feel claustrophobic with ceilings lower than 9 feet, thus 10 foot ceilings are preferred. But even 12 or 13 feet is acceptable if you don't feel crowded.
The average width of a room is about 15 feet, although this can vary depending on the type of room it is. A living room for example will be much wider than a closet or storage space.
The length of a room is generally determined by the size of the house itself. In an apartment building for example, the rooms are usually very short. Sometimes two separate rooms are joined together with a shared wall to create one large room. This is called "tackifying" the walls.
The size of your bedroom should give you enough room to move around in without feeling cramped. You should have space to walk around the bed and look at all sides of the room without running into anything.
If the room you're looking at doesn't meet these requirements, then perhaps another room in the house could be converted into a master bedroom. Master bedrooms are usually larger than regular bedrooms and include other amenities such as a bathroom or shower area. These rooms may also have multiple windows for natural light.
A two-story home with average high ceilings (9 feet high) stands around 20 feet tall. This includes additional footage from the depth or thickness of the floor (typically one foot) and space above the ceiling (up to 2 feet in homes with drop ceilings). When you add this surface area to the base of the house, you get an idea of how much room there is up on those walls.
There are 1-foot wide windows in most 2-story houses. Windows are usually framed with wood and covered with glass. They may have shutters for extra protection from the elements. The frame itself is about 1/4 inch thick.
Two-story houses were once all wood. But now many are made out of brick or stone. These larger-scale buildings need thicker walls to support their weight.
The roof of a 2-story house is usually flat, although some have gables or other shapes instead. They're usually made out of metal or shingles but once existed in great numbers in America's west coast cities. A wooden 2-story building will typically have cross-bracing to hold the roof together while a stone or brick one won't need such support.
The ground floor of a 2-story house is called the first level.
