Before a house becomes habitable, it undergoes a lot of documentation and construction work.

This work starts with land acquisition, proper documentation, and finding the right architect and engineers to make it your desired home.

Indeed, all of these activities lead to the comfortability of a home.

While knowing the above is good, you need to know the right sizes of rooms to enjoy the maximum benefit of owning a home. This knowledge is useful to those building a new home from scratch, buying an already built house, and old homeowners planning an extension.  

Maximum space utilization comes with adequate knowledge of what is to be done, how it is to be done, and where it is needed. When done right, space utilization proves to enhance the quality of your home, and invariably your life.

It provides adequate sunlight into the house, enough space for proper movement and daily activities, and proper ventilation.

Living room

Every part of a home is important, but some play a key role than others. The living room is one of the most important and frequently used rooms. As a result, it has the highest traffic in a home.

The living room, also known as the drawing-room, must be comfortable for family members to sit, chat, and receive guests. It should be connected with the dining room and the front verandah, explaining why it is advised to be in the middle of the house.

It also serves as a reception room, and with more guests on special occasions, it serves as a dining room. For all of these reasons, the living room is the biggest in the house and must be well ventilated, arranged, and lighted.


Standard sizes of a living room in meters and feet
  • Very small 3.05 × 3.66 and 10' × 12'
  • Small 3.66 × 5.49 and 12' x 18'
  • Medium 4.88 x 6.01 and 16' x 20'
  • Large 6.71 x 8.53 and 22' x 28'

Sometimes, the size of the sofa (three sofas) and sitting position play a role in determining what size a living room should be. In cases like that, the standard size is 7.6m x 6.1m (46.36m²) using the master sofa and two secondary sofas as the benchmark.


Dining room

There's generally less traffic around the dining hall compared with the living room. The dining room comes next to the living room, intercepting the kitchen and living room.

Recently, both are combined in the same space to ensure maximum space utilization and accommodate a large number of guests during special occasions. Several factors will determine the space size of a dining room; these are:

  • Dimension of the table, if bought or selected before you built the house
  • Availability of the recommended circulation space of 1m to 2m around the table, on at least two sides of the table
  • Personal choice of dining. Whether a separate room, combined with the living room or with the kitchen

Two important considerations for situating a bedroom are ventilation and privacy. While for size are functionality and bed size. These considerations explain why bedrooms are made on the sides of the house to ensure ventilation, privacy, good lighting, and adequate sunlight during the early hours of the day.

Master Bedroom

To determine the size of a master bedroom, you must consider all the essentials of a standard bedroom: ventilation, privacy, exposure to sunlight, and the prevailing wind.

You need not worry; we've got you. But first things first.

A kitchen should be well ventilated and positioned for adequate sunlight. It should have a chimney for smoke and be fitted with shelves and a sink.

Bathroom and Toilet

In modern-day homes, it's a common practice to have a bathroom and water closet in individual bedrooms. These bathrooms are mostly attached to the bedroom. In cases of large spaces, they are built at the rear corner of the house with each separated to serve two people at once. Regardless, it should be well ventilated.

What size should a utility room be?

Wide enough to take all the messy items. It can be as small as 1.8 x 2.4m (4.32m²) or as big as 2.4 x 3m (7.2m²).

This space is enough for free movement and to accommodate your washing machine, work tools, tumbler dryer, and storage cabinets. If you envision all these plus a dog shower or pet bed, the ideal size is 2.4 x 3m (7.2m²).



A foyer is a lobby after the front door but between the entrance of the living room. It isn't available in all homes as some homeowners prefer the living room serves this purpose.

A house isn't yet a home if it's not functional, convenient, and comfortable for the owner.
