Steps To Use The Board Foot Calculator

  • Enter the length, width, thickness, and number of pieces of the board in the designated input fields.
  • Select the appropriate unit of measurement for each field using the drop-down menu. The available options are inches, feet, and meters.
  • Click the “Calculate” button to determine the total volume of the board.
  • The result will be displayed on board feet and rounded to three decimal places.
  • Repeat the process for any additional boards you need to calculate.

Note: Ensure that you use consistent units of measurement for length, width, and thickness when calculating the board foot volume.

What is Board Foot?

A board foot is a standard unit of measurement adopted by sawmills and wholesalers when dealing with timber. It is used to determine the volume of lumber. For those in the industry, being able to figure out the volume of wood is an effective way of quickly determining the amount of wood in their possession.

One board foot is equivalent to 144 cubic inches. This unit of measurement is used widely in the lumber and wood industry as a standard unit for determining the volume of lumber, which is crucial for determining the amount of material needed for a project and for pricing purposes.

One board foot is the square foot area of lumber multiplied by the thickness of lumber(in inches).

For ease of understanding 1 ft x 1ft piece of lumber which is 1-inch thick will form 1 board foot.

Whereas 1ft x 1ft of lumber piece having a thickness of 2 inches will be called 2 board feet.

How The Board Feet are calculated?

To calculate the board feet one has to measure the length, width, and thickness of the lumber piece. The best way is to measure all dimensions in inches. To calculate board foot by measurements in inches follow the below steps.

  1. Measure the length of the lumber piece in inches, for example, we consider the length as 200 inches.
  2. Measure the Width of the lumber piece in inches as well, let us consider the width as 50 inches for now.
  3. Now measure the thickness of the lumber piece in inches, consider the thickness as 2 inches.

Board Foot: 200 inches (length) X 50 inches (Width) X 2 inches (Thickness) 

Divide Length & Width which is in inches by 12 to convert them into feet:

= (200/12) X (50/12) X (2)

=16.6666 x 4.1666 x 2

= 138.88 Board Feet 

Note: If measurements are taken in feet then there is no need to convert them into feet by dividing by 12, simply multiply Length(Feet) X Width (Feet) X Thickness(inches).

Board Foot Calculator

Calculating board feet can be a time-consuming and potentially error-prone process but with the use of a board feet calculator, this task becomes much easier and more efficient.

A board feet calculator is a digital tool that allows you to input the dimensions of your lumber and instantly receive an accurate calculation of its volume in board feet. The app does all the hard work for you, eliminating the need for manual calculations and reducing the risk of errors.

One of the biggest benefits of using a board feet calculator is its convenience. You can use it anywhere, anytime, without the need for a paper and pen.

Here are the steps you need to follow to get an accurate calculation of your lumber’s volume using the calculator: 

  • Start by launching the calculator.
  • Then, input the relevant information regarding the width, length, and thickness of the board you wish to measure. Make sure to select the appropriate unit of measurement for each measurement, whether it be inches or feet.
  • Add the number of pieces.
  • Once you have entered all the necessary information, hit the “calculate” button to receive an instant calculation of your board’s volume.
  • Repeat the same steps for additional pieces of lumber with different dimensions.
