How to use this tool

  1. Enter thickness, width, length, number of boards.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Volume = thickness(mm) × width(mm) × length(m) × count/10⁶.

A WORKED EXAMPLE

Using thickness = 50 mm, width = 150 mm, length = 3 m, number of boards = 10, the result is 0.225 m³. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.

Common questions

Which inputs does this calculation need?
