πŸ’‘ How to Calculate Concrete Column Volume

For rectangular columns: volume = width Γ— depth Γ— height. For round columns: volume = Ο€ Γ— rΒ² Γ— height. Common residential columns are 12Γ—12 inches square or 12 inches diameter. Structural columns may be 18–36 inches.

All concrete columns require reinforcement β€” typically 4 vertical #5 or #6 bars with #3 ties every 12 inches. Forms must be plumb, braced, and oiled before pouring. Vibrate the concrete during placement to eliminate air pockets.

Four 12Γ—12 inch square columns Γ— 10 ft tall: volume each = 10 cu ft. Total = 40 cu ft = 1.48 cu yd β‰ˆ 67 bags of 80 lb mix.
