According to the National Building Code (NBC), the standard ceiling height is ninety-six inches, or eight feet; for suspended ceilings; the minimum height is ninety inches, or seven and a half feet. But nine- and ten-foot ceilings are now common, not only in living rooms and kitchens, but also in bedrooms.

Bathrooms, toilet rooms, kitchens, storage rooms and laundry rooms shall have a ceiling height of not less than 7 feet (2134 mm) above the finished floor.
A ceiling height of 2.3 to 2.4 m from floor to ceiling is recommended for a comfortable, functional loft conversion. The absolute minimum low end is 2.1 m for basic use. Ceiling height on staircases must be at least 2 m to meet building codes.
The ceiling height standard in most regions is 9 feet, giving homes more open space and room for overhead additions, like ceiling fans. Meanwhile, the minimum height is 7 feet, though it can be as low as 6 feet, 8 inches in the bathroom and laundry rooms.
Habitable rooms provided with artificial ventilation shall have ceiling heights not less than 2.40m. For buildings of more than 1 storey, the minimum ceiling height of the first storey shall be 2.70 m, for the second storey, 2.40 m.

The average or standard ceiling height as of present is 9 feet. This wasn't the case before since, at some point, the standard ceiling height was 10 feet. Nevertheless, now, most contractors have agreed on 9 feet. Unfortunately, you may come across 8-feet ceilings since many boards come in eight-foot pieces.
The minimum ceiling height for bathrooms and toilet rooms is 6 feet, 8 inches (2032mm).
In the 1970's, the average ceiling height was 7 feet 9 inches. Today a standard ceiling height is nine feet on the first floor and eight on the second. Here are some other comparisons from House & Garden: In 1974, one in four homes had at least four bedrooms.
It might not be the first thing you notice about a room, but ceiling heights play a huge role in a home's overall look and feel. Super high, vaulted ceilings make homes feel spacious and regal, while cramped, low ceilings can make a room feel outdated or claustrophobic.
The rationale behind these minimum ceiling heights is rooted in ensuring occupant comfort and safety. Higher ceilings contribute to an inviting atmosphere, allow more natural light to enter the space, and accommodate taller furniture.
A shower or tub equipped with a showerhead shall have a ceiling height of not less than 6 feet 8 inches (2032 mm) above an area of not less than 30 inches (762 mm) by 30 inches (762 mm) at the showerhead.
The general rule is 1 foot for every 3 inches, meaning that for every foot in height your room is, the chandelier should be 3 inches. For example, in a standard 8-foot ceiling height bedroom, the light should hang no lower than 24 inches.
As per the NBC, the minimum ceiling height for habitable rooms in a residential home should be 9 feet from the finished floor level. For non-habitable rooms such as storage areas, the minimum ceiling height requirement is 7 feet 10 inches.

Building regulations and minimum ceiling heights
The national standard sets a minimum floor to ceiling height of 2.3m for at least 75% of the gross internal area.
On the minimum ceiling heights the IRC requires habitable spaces and corridors to be a minimum of 7′-6″ and bathrooms, kitchens, storage areas and laundry areas can have ceilings at 7′-0″ minimum.
Standard ceiling height inside a house is 8 feet. To feel spacious, your porch should also have at least 8 feet of ceiling height, but porches with even taller ceilings are quite traditional. However, the deeper the porch, the lower the front eave will be for a given roof slope.
A 9 ft ceiling is usually considered standard. In newly built houses, you will find that the ground floor has a 9 ft ceiling, while the first floor has an 8 ft.
A 10x10 room is considered small for a bedroom, especially by modern standards. While it can accommodate essential furniture like a bed, a small wardrobe and a desk or bedside table, the space is limited.
In general, the smallest size is 15 square feet, which can fit a sink and a toilet. For a shower, to be installed, at least 30-36 square feet is required. For a full bath consisting of both a shower and a bathtub, you will need at least 40 square feet.
Bedrooms can still be called bedrooms without the closet. Many older homes have bedrooms without the closet option. As a substitution, you could always put in an armoire or full height dresser/rack combo.
