Concrete Column Calculator

Estimate concrete for round and square columns, pillars, and piers. This concrete column calculator computes volume per column and total project volume for accurate ordering of ready mix or bagged concrete.

Column Volume Formula

Round: pi x radius² x height x count. Square: side x side x height x count

Hur man använder det här verktyget

Concrete Column Calculator FAQ

Tydliga svar på vanliga frågor om uppskattning och planering.

How do I calculate concrete for a round column?

Use the cylinder formula: pi x radius squared x height. Convert the diameter from inches to feet first, then divide radius by half.

What is a typical concrete column diameter?

Residential columns are commonly 8 to 16 inches in diameter. Commercial and structural columns can be 24 inches or larger.

Can this calculate block-filled columns?

Yes. Use the volume output to estimate the concrete needed to fill block or CMU columns with rebar-reinforced concrete.
