Board Foot Calculator

Calculate Board Feet









Definition

A board foot is a wood measurement for a piece of lumber 12" wide by 1' long by 1" thick for estimating purposes. Learn how to figure total board feet in your next stack of lumber below.

Formulas

To calculate the board feet:

\[ \text{Board Feet} = \frac{\text{Thickness (inches)} \times \text{Width (inches)} \times \text{Length (feet)}}{12} \]

For multiple pieces:

\[ \text{Board Feet} = \frac{\text{Number of Pieces} \times \text{Thickness (inches)} \times \text{Width (inches)} \times \text{Length (feet)}}{12} \]

Description

To calculate the board feet, you need to:

  1. Determine the thickness of the lumber in inches.
  2. Determine the width of the lumber in inches.
  3. Determine the length of the lumber in feet.
  4. Multiply the thickness, width, and length together.
  5. Divide the result by 12 to get the board feet.

Example Calculation

To calculate the board footage in an 84 piece unit of 2 x 8 - 12:

\[ 84 \times 2 \times 8 \times 12 \div 12 = 1,344 \text{ Board Feet} \]
