Wood & lumber / 01

Board Foot Calculator

Calculate materials, optimize cutting layouts and estimate costs. Make every measurement count.

Planning estimates; verify measurements and product data before purchasing.

Your measurements

Nominal and actual dimensions

Enter measured actual dimensions above. Nominal lumber names are trade labels and vary by region, processing and supplier. There is no universal nominal-to-actual conversion. Record the nominal label below, but always calculate with verified actual sizes.

DIY MATERIAL LAB

Your material plan

Enter your measurements to build a material plan.

Use actual thickness, width and length in metres. One board foot equals 0.002359737216 cubic metres. Multiply the volume of one board by the number of boards before converting. A nominal trade label describes a product family and may differ from its measured dimensions; verify the supplier's actual size. Price here is per board foot.

Calculation method

BF = t × w × L × n / 0.002359737216; V = t × w × L × n

Measure. Calculate. Build.

  1. Use actual dimensions and split complex rooms into rectangles.
  2. Allow for cuts, joints and package sizes. Compare stock formats.
  3. Combine your results in a shopping list you can save and print.
