Information of Building Dimensions
Buildings serve as universal carriers of art, culture, history, economics, and equity while also providing us with basic human necessities such as shelter, security, privacy, storage, and labour.
These fundamental features and concepts make up the majority of our built environment, which includes residential, commercial, civic, educational, medical, industrial, agricultural, and infrastructural functions.
The following guides offer an overview of the many construction processes, systems, components, materials, logics, and standards that influence how buildings are built around the world.
These materials will continue to grow and improve over time in order to better demonstrate and chronicle the numerous subjects and concerns surrounding construction.
Structure bye-laws, which often dictate the bold and underline(standard dimensions of residential building) and the bold and underline(standard size of building components), are restrictions imposed by municipal, urban development, and other government departments.
Therefore it is necessary to prepare the proposed building plan according to the bye law which is verified and endorsed by the authorities mentioned above. The building standards in residential buildings are decided by this procedure.
Builder height means the average vertical maximum elevation of a building or structure measured from the finished gradations.
The building or structure does not include architectural items that do not add floor space, such as parapet walls, chimney, windshields and roof equipment
What Is the Dimension of Building?
A dimension is a derived unit used to measure a physical quantity such as length, width, height, distance, area, volume, mass and time.
A dimension is a numerical value expressed in an appropriate unit of measure. It is indicated on drawings along with lines, arrows, symbols, and notes to define the size and specification of an object. Linear Dimensions are used for displaying and measuring length along the X or Y axis.
The Graphics’ industry standard is width by height (width x height). Meaning that when you write your measurements, you write them from your point of view, beginning with the width. That’s important.

Standard Dimensions Below Are Building and Building Design,
- The minimum foundation depth, a crucial aspect when considering the bold and underline(size of building), is kept 1 metre below ground level. The foundation’s width should be so large that the soil’s stress is securely carried.
- Minimum plinth dimension: Height of a plinth can be between 300 mm to 600 mm. The minimum plinth height is 600 mm for accommodation at water-prone and important buildings. The building has a majestic appearance with a larger plinth height.
- The area of the plinth should be at least 1,2 times the building floor area. The standard brick depth of 100 mm is 100 m wider than the previous one, and the base depth is 100 mm lower.
- When a certain number of bases are to be supplied, their depths are preferably equal. The width of the base bed for cement concrete = the width of the base of the brick just above the bed of concrete + 100 mm + 100 mm. (i.e. 100 mm for the concrete bed is the minimum offset).
- Minimum base width = 2t + 2j
- Where, t = Wall thickness just above the basement (Not less than 200 mm )
- j = concrete offset (Not less than 100 mm)
- Damp-proof course 20 to 25 mm in thickness.
- The cement floor thickness is at least 100 mm plus floor finish. Typically, the floor finishes with cement morter or tiling are 10 mm to 20 mm thick.
- The height of the ceiling (i.e. headroom) should be between 3000 mm and 3600 mm for the main rooms of the residual structure. For bath and W.C. the ceiling height may be 2000 mm to 2750 mm. (The building’s maximum height depends on structure types)
- The carpet should cover 50 to 65 percent of the total floor space.
- A residential building’s main entrance door should be 1000 mm x 2100 mm in size. Other doors should be a minimum of 900 mm wide and 2000 mm tall. With the single-leaf shutter, garage doors are 2500 mm x 2300 mm, and W.C. and bathroom doors are 600 mm to 750 mm x 1800 mm.
- The size of the windows is determined by the overall area of the needed window apertures.
- It’s important to remember the following guidelines:
- Window width = 1/8 (room width Plus room height).
- For excellent illumination, the glass area in windows should be 10% to 20% of the room’s floor area.
- For every 30 cubic metres of interior room space, at least one square metre of window area should be supplied.
- The minimum window size is usually 750 mm by 1000 mm.
- To ensure enough ventilation for every livable room, a ventilator must be at least 1000 mm × 500 mm in size. A minimum of 450 mm x 300 mm should be used for the bath and the toilet. If the depth is larger than 450 mm, privacy is lost.
- In a residential construction, the rise ranges from 130 to 190 millimetres.
- In an office building, the rise is between 125 and 150 millimetres.
- For public structures, the range is 275 mm to 350 mm.
- For residential buildings, go from 250 to 300 mm.
- The following guidelines are used when choosing a building’s rise and tread:
- T x R = 39000 to 48000 T x R = 550 to 650
- The width of steps in residential structures is 900 mm, whereas in public buildings it is 1000 mm.
- (Total Floor Height / Riser Height) x (Number of Risers)
- The number of treads equals the number of risers minus one.
- R.C.C. I lintel beam thickness ranges from 100 mm to 250 mm, with 150 mm being the most common.
- The thickness of an R.C.C. roof slab ranges from 100 mm to 150 mm (100 mm is more common), while that of sunshades ranges from 25 mm to 50 mm.
- Sunshade projection length in centimetres: sunshade projection through 450 mm or 500 mm beyond the external wall facing.
- In residential houses, the width of the verandah ranges from 1.8 m to 3 m, while the width of the passage ranges from 0.8 m to 1.2 m.
- The wall should not reach less than 0,60 m above the finished floor, and should not exceed 1,2 m.
- Height of different building materials and standard building height
- The mezzanine floor area may not exceed one-third of the floor area or the mezzanine floor area.
- The headroom measured at the underside of the mezzanine floor should not exceed 2,2 m from the floor’s surface to any point.
- The room height shall not be less than 3.00 m in the apartment building provided that it is not less than 2.4 metres in the case of air-conditioned rooms.
- At least one water closet must be provided for each building.
- The bathroom area shall not be less than 1.50 m2 and the latrine carpet area shall not be less than 1.1 m2, one side not less than 1.0 m2
- In so far as there is no less than 2.2 square metres, one side no less than 1. 1 metre, in the area of combined bath and latrine: the height of the bath or latrine shall not be less than 2,20 m.
- Ramps shall be placed on the slopes not greater than one in 10 if provided as a substitute for the steps and such ramp shall satisfy all staircase requirements and shall be surfaced with the approved non-slippery materials.
- Any hallway, verandah, or walkway in a building must have a clear width of at least 1.0 metres at all times.
- Every structure intended for human habitation must have an emergency exit large enough to allow residents to safely evacuate in the event of a fire or other emergency.
- The location of emergency exits on each floor must be such that the total travel distance for each occupant does not exceed 30 metres.
- Part IV, Fire Protection in the National Building Code of India, 1983, and amendment No. 3 under Fire Protection Annexure 11 should apply to all fire protection standards.
- Exit widths shall be 50 cm, clear width 25 cm, and clear width less than 25 cm for exit widths. The output width unit used to measure the capacity of any exit shall not be counts for exit width.
- For every building with residential occupancies over three floors above the floor, other than residential occupancies over 2 floors above ground level, fire escape stair case should be provided.
