There’s nothing like standard sizes but only recommended ones. You can still get some idea on how the sizes are different.

It is very important to have knowledge of standard dimensions and size required for various parts of buildings. This helps in proper planning of a building making spaces for movement, ventilation, and sunlight for the residents.

Town and Country Planning Organisation, Ministry of Urban Development, has published Model Building Bye Laws 2016 for minimum requirements for various parts of building which are as follows:

Part 4 – General Building Requirements and Services:

  • 4.3 – Habitable Rooms:
    • 4.3.1 – Height:
      • The height of all rooms for human habitation shall not be less than 2.75 m measured from the surface of the floor to the lowest point of the ceiling (bottom of slab) provided that the minimum clear headway under any beam shall not be less than 2.4 m.
      • In the case of pitched roof, the average height of rooms shall not be less than 2.75 m.
      • The minimum clear head room under a beam, folded plates or eaves shall be 2.4 m.
      • In the case of air-conditioned rooms, a height of not less than 2.4 m measured from the surface of the floor to the lowest point of air-conditioning duct or the false ceiling shall be provided.
  • 4.3.1.2 – Size:
    • The area of habitable room shall not be less than 9.5 m2, where there is only one room with a minimum width of 2.4 m.
    • Where there are two rooms, one of these shall not be less than 9.5 m2 and the other not less than 7.5 m2, with a minimum width of 2.1 m.
  • 4.4 – Kitchen:
    • 4.4.1 – Height:
      • The height of a kitchen measured from the surface of the floor to the lowest point in the ceiling (bottom of slab) shall not be less than 2.75 m, except for the portion to accommodate floor trap of the upper floor.
  • 4.4.2 – Size:
    • The area of a kitchen where separate dining area is provided, shall be not less than 5.0 m2 with a minimum width of 1.8 m.
    • Where there is a separate store, the area of the kitchen may be reduced to 4.5 m2.
    • A kitchen, which is intended for use as a dining area also, shall have a floor area of not less than 7.5 m2 with a minimum width of 2.1 m.

Different rooms serves a particular purpose and considering above guidelines, Standard size of Rooms in Residential Building can be planned as follows:

  1. Bedroom:

Minimum – 3.0m x 3.6m = 10.8 m2 or 10ft. x 12ft. = 120 sqft.

Maximum – 4.2m x 4.8m = 20.16 m2 or 14ft. x 16ft. = 224 sqft.

  1. Drawing Room:

Minimum – 4.2m x 4.8m = 20.16 m2 or 14ft. x 16ft. = 224 sqft.

Maximum – 5.4m x 7.2m = 38.88 m2 or 18ft. x 24ft. = 432 sqft.

  1. Guest Room:

Minimum – 3.0m x 3.6m = 10.8 m2 or 10ft. x 12ft. = 120 sqft.

Maximum – 4.2m x 4.8m = 20.16 m2 or 14ft. x 16ft. = 224 sqft.

  1. Dining Room:

Minimum – 3.6m x 4.2m = 15.12 m2 or 12ft. x 14ft. = 168 sqft.

Maximum – 4.2m x 4.8m = 20.16 m2 or 14ft. x 16ft. = 224 sqft.

  1. Kitchen:

Minimum – 2.5m x 3.9m = 9.75 m2 or 8ft. x 13ft. = 104 sqft.

Maximum – 3.6m x 4.2m = 15.12 m2 or 12ft. x 14ft. = 168 sqft.
