Proportions play a very significant role in architecture because they have different feelings associated with them and depend on how a human perceives objects with the surrounding spaces. Proportions affect working efficiency by creating positive or negative stimulus in the human brain. The beauty of nature is because every object is provided with an attractive proportion vis-à-vis its surroundings. Beautiful architecture should also evoke such chemical changes in our brain which stimulates a feeling of pleasure or happiness. This paper deals with different types of proportions and the feelings generated by them in two and three dimensional spaces. On varying the size, mass or volume of various building elements, we generate bulky, young or light proportions. These proportions can promote the feeling of strength or weakness, stability or instability, openness or closeness, fear or security, depending upon its surroundings.

Vitruvius (1960), in his book, The Ten Books of Architecture, said, “Proportion is a correspondence among the measures of the members of an entire work, and of the whole to a certain part selected as standard”.

Proportions play a very significant role in architecture because they affect how humans perceive objects and spaces. Proportions have different types of feelings associated with them. They may lead to the feeling of pleasure or sadness, congestion or openness, integrity or incompleteness, etc. For example, when we proceed from outside to the inside of Taj Mahal through a narrow staircase, with each step our feelings begin to vary from openness to mystery through congestion.

Proportions have an effect on human mind and working efficiency, not only in two dimensions but also in three dimensions. We are attracted to those proportions which cause positive stimulus in the human brain. Imperfect proportion creates the feeling of incompleteness and distraction. This paper discusses how proportions help in the stimulation of different thoughts.
