About Concrete Calculator Cylinder

Our concrete calculator cylinder tool is specifically designed for calculating concrete volume in cylindrical structures. This is perfect for columns, posts, sonotube footings, and other round concrete elements.

Common Cylindrical Applications

  • Deck Posts: Support columns for decks and porches
  • Fence Posts: Concrete footings for fence installations
  • Structural Columns: Load-bearing columns in buildings
  • Sonotube Footings: Round concrete forms for foundations
  • Light Poles: Street light and parking lot light foundations
  • Flag Poles: Concrete bases for flag pole installations

How to Measure Your Cylinder

  1. Diameter: Measure across the widest part of the cylinder (inside diameter for forms)
  2. Height: Measure from bottom to top of the concrete structure
  3. Quantity: Count how many identical cylinders you need

Standard Sonotube Sizes

Small Projects

  • 8" diameter - Small posts, light fixtures
  • 10" diameter - Deck posts, small fences
  • 12" diameter - Standard deck posts

Large Projects

  • 16" diameter - Large deck posts, structural columns
  • 18" diameter - Heavy structural support
  • 24" diameter - Large structural columns

Tips for Cylindrical Concrete

  • Always add 10% waste factor for spillage and uneven ground
  • For sonotube footings, measure the inside diameter of the form
  • Consider using concrete bags for small quantities (under 1 cubic yard)
  • Order ready-mix concrete for larger projects or multiple cylinders
  • Ensure proper reinforcement (rebar) for structural applications
