There is no specific rule to determine the desired distance between reinforced concrete columns. Factors like architectural considerations, the function of the building, and the structure's load play a significant role in determining an optimum span between two reinforced concrete columns.

Architectural engineers often fancy the largest possible distance, whereas structural engineers are concerned about the building's safety and economy. Sometimes, structural and architectural engineers compromise based on their needs, but it is important to ensure that the building's function does not change. There are cases when there is no scope for any changes in the architectural plans; hence structural engineers cannot provide any suggestions regarding the plan of the building.

Generally, the increase in the distance between reinforced concrete columns would require an increase in beam depth and sometimes the dimensions of the columns. So, the designer should select a spacing that results in optimum sizes for beams and columns. Improper column spacing causes poor utilization of spacing inside the building.
