Column size and span are closely related in structural engineering. The appropriate column size depends on the span it needs to support and the load it must carry. For a general estimate, a 20-foot span might require a 12×12 inch column, but precise sizing should always be determined by a structural engineer considering specific project requirements and codes.

FAQs
How is column size calculated? Column size is calculated based on various factors, including the structural load it needs to support, the material used (e.g., concrete or steel), local building codes, and engineering calculations. There isn't a single formula for column sizing, as it depends on the specific project's requirements and constraints.
What is the column size for a 20 feet span? The column size for a 20 feet span would depend on several factors, including the load-bearing capacity of the material and the design specifications. For an estimation, a reinforced concrete column for a 20 feet span might typically have dimensions of approximately 12 inches by 12 inches (12"x12").
What is the size of the column for an 8-meter span? For an 8-meter span, a reinforced concrete column might have dimensions of approximately 30 centimeters by 30 centimeters (30cm x 30cm). Please note that this is a rough estimation, and the actual size would depend on engineering calculations.
What is the size and span of a concrete column? The size and span of a concrete column can vary widely depending on the specific project and structural requirements. Concrete columns can have various sizes and spans, ranging from small residential columns to large industrial ones. There is no one-size-fits-all answer.
What is the rule of thumb for sizing columns? A common rule of thumb for sizing columns is to use a 1:6 to 1:10 ratio of the width of the column to the height. For example, if you have a column that is 12 inches wide, it might be suitable for a height of 6 to 10 feet. However, this is a general guideline and should be validated by an engineer for each specific project.
