Concrete Column Calculator
Calculate the volume of concrete needed for columns in your construction project, along with reinforcement requirements.
Calculate Your Concrete Column Calculator
Concrete columns are vertical structural elements that transfer loads from beams and slabs to the foundation. Accurate calculation of concrete volume and reinforcement is crucial for structural integrity and cost efficiency.
When designing concrete columns, factors such as column dimensions, concrete grade, reinforcement requirements, and loading conditions must be considered. This calculator helps you determine the concrete volume needed for your columns.
How to Use This Calculator
- Select the column shape (rectangular or circular).
- Enter the dimensions of your column.
- Select the concrete grade based on your structural requirements.
- Specify the reinforcement details (number of longitudinal bars, bar sizes, and tie specifications).
- Click "Calculate" to get the concrete volume and reinforcement requirements.

Frequently Asked Questions
For a standard 12×12 inch square column that's 10 feet tall, you would need approximately 10 cubic feet (0.37 cubic yards) of concrete. The exact amount depends on the column's cross-sectional shape and dimensions.
According to most building codes, the minimum longitudinal reinforcement in a concrete column should be about 1% of the gross cross-sectional area, and shouldn't exceed 8%. Ties or spirals are also required at specific spacings.
In residential construction, concrete columns typically range from 8×8 inches to 12×12 inches for square columns, depending on the load they need to support and local building code requirements.
