How do I calculate a square column?
Enter the same value for width and depth to model a square cross-section.
Column Concrete Calculator
Calculate concrete volume for rectangular columns by cross-section, height, and quantity.
Column Concrete Calculator Formula
- Column Cross-Section
Width × Depth - Single Column Volume
Cross-section × Height - Total Volume
Single column volume × Quantity - Wastage Allowance
Total volume × (1 + Wastage ÷ 100)
Assumptions
- Columns are modelled as rectangular prisms with uniform cross-section.
- Footing and pedestal volumes are excluded unless included in height.
- Circular columns are not supported in this version.
Frequently Asked Questions
Should height include the footing?
Include only the vertical column shaft unless you intentionally add footing depth to the height field.
Can I calculate multiple columns at once?
Yes. Enter identical dimensions and set the quantity to the number of columns.
