Standard Ceiling Heights Australia

In Australia, this term is described as the height from the finished floor to the lowest point on any ceiling above it. This may be a beam, duct or other obstruction.

In Australia, it is an allowable obstacle that can restrict headroom at least 2,400 mm from sloped ceilings and 2400 mm from flat ceilings in all rooms except bathrooms and toilets, utility rooms, hallways and large passageways. Note that it is recommended to have at least a total clearance of 2400 mm above the floor in all rooms, including bathrooms and toilets.

Even though it’s called typical or average, there is no actual statistic collected anywhere that would describe how many homes do actually follow the standard. Therefore “typical” is a subjective term.

The terms “low ceiling” and “high ceiling” usually refer to the actual height, which can make it easier to understand. A low ceiling might be anything below 2000 mm (approx 6 ft 6 inches) whereas a high ceiling would most likely be above 2600 mm ( approx 9 ft).

Standard Ceiling Height Australia

The standard ceiling height in Australia is typically around 2.4 m (8 ft).

Even though it’s called typical or average, there is no actual statistic collected anywhere that would describe how many homes do actually follow the standard. Therefore “typical” is a subjective term.

Average Ceiling Height Australia

For example, in a typical Australian home the ceiling would be around 2.4 m (8 ft). It depends on its function and use. Homes used for entertainment purposes such as lounges and living areas may have higher ceilings, whereas bedrooms usually have lower ceilings.

So there is no set standard and actual heights may vary between homes.

Standard Ceiling Height

The low ceiling is around 2.1 m (7 ft). They are mostly used in limited space areas such as garages, basements, corridors and some living spaces like family rooms etc. It’s usually non-habitable rooms.

Standard Roof Height Australia

The standard roof height is 4.6 m (15 ft). This is the maximum height from the finished floor to any eaves above it, assuming there are no additional obstacles such as a wall, window or door below the ceiling. Rooms with a low ceiling may have less headroom than rooms with high ceilings.

Ceiling Height

Homes with a high ceiling often have more value than those with lower ones because of their increased usability. The average ceiling height in Australia is up to around 2.9 m (9 ft 6 in).

Even though a high ceiling is often recommended especially if you have tall people living with you or for entertaining purposes, there are some disadvantages to them as well. For example, tall people usually feel uncomfortable under a low ceiling while the reverse is true for short people.

Standard Room Height

The average room height is around 2.4 m (7 ft 10 in). Although the maximum headroom depends on the person’s height, this is an average reference point to judge if a ceiling is low or high. This is also helpful for people who are not very tall or moderately sized. For example, you can use it to calculate how many rugs you need to cover the floor.

Ceiling Heights in Old houses

The ceilings in old houses are likely to be lower than those in modern ones. In some cases, main rooms may have a similar height to current habitable rooms, but smaller non-habitable rooms like studies and box bedrooms often had lesser ceiling heights.

The term is also used with reference to the unobstructed vertical distance between an object or surface and the ceiling. For example, a picture hanging on your wall may leave you with 2 inches of ceiling height.

Although there are many advantages, high ceiling homes may require special care and structural strength as well as ventilation. This means higher maintenance costs and can sometimes be problematic as well (for example if you want to install a custom made chandelier).

The standard ceiling height does not limit how high your ceilings could be, but it’s a good rule of thumb when planning a new home in Australia.

Minimum Ceiling Height Australia

The minimum ceiling is about 2.1 m in height (6 ft 11 in). They are mostly used as bathrooms and laundries because of their practical purpose. It’s not a very common type of home design but there is no actual reason why you cannot have one either.

Ceiling Heights Building Regulations

A habitable room cannot have a ceiling lower than 2.4 meters according to the building code of Australia. A kitchen, laundry, hallway, and corridor do not constitute a viable space, and their height can be up to 2.1m.

Ceiling Heights

Some builders and architects have their own rules. For example, a rule of thumb is to have a minimum ceiling height of 2m in the main rooms of a house, and at least 1.7 m in the smaller secondary rooms.

Australian ceiling height standards are based on three different types of spaces: habitable rooms, corridors and halls.

Average House Height

This is a rough estimate of what you can expect:

  • The first storey ceiling height is 2.4 m with a tiny variance as low as around 2.1m to as high as 2.8 m.
  • The second storey ceiling height is usually within the range of around2 m to 2.4 m
  • The overall height of a two-storey house is around 3.4 m. But if we take the roof line into account, this may be as high as 6.1 m.

2.7m Ceiling Height

A 2.7 m (8 ft 10 in) ceiling height is also common with variation between around 2.5m to 3 m depending on the use of the room. A habitable room such as a dining room, living room, family room or lounge rooms with a higher ceiling may be built at least 3 m high while bedrooms are most times not that tall.

Standard Wall Height

The standard wall height is 2.4 m (7 ft 10 in). This does not vary much, but there are a few unusual cases of larger or smaller walls. For example, the hallway may have a very low ceiling at around 2m high, especially if there is a basement area beneath it.

Minimum Ceiling Height Building Code

You have to remember that even if the code allows you to have a low ceiling, you should not compromise on comfort. If you are a tall person, it would hurt your neck and head every time you enter the house or sleep on a low bed. Another thing is that colder air falls, so it’s important to have a high ceiling to keep the hotter air closer to the roof.

Standard Ceiling Height Australian houses

The standard height for normal rooms in Australia is 2.4 m (7ft 10in) which comprises the floor to ceiling height, but there are some exceptions where it can be less or more. According to the building code of Australia, living rooms cannot have a height less than 2.1m while bathrooms and laundries are allowed to have a height of fewer than 2.4m with the variation allowed.

Normal Ceiling Height Australia

The height of a normal bedroom is about 2.1m (6ft 11in), but sometimes it can be as low as 1.7m (5ft 7in) for small bedrooms, especially in the older homes with smaller rooms designed to fit only a bed and a dresser.

It’s better to have a higher ceiling because it helps to create a sense of openness and comfort and you can attach some ceiling fans. Unfortunately, this is not always possible and you’ll have to make some compromises depending on your budget and personal taste.

Standard Ceiling Heights Australia

The minimum height in the hallway is 2.4 m (7 ft 10 in) while you can have a height of around 2 m for bathrooms and laundries. The variation in the living room, kitchen, family room and dining room is between 1.85m and 2.4m.

Minimum Ceiling Height NSW

A building inspector may not let any home owners to build lower than 2.4m in height for habitable rooms. For secondary rooms, it may be up to 2m high and in any other utility room, it may be up to 2.1m in height.
