Board Foot Calculator

Calculation results

A board foot calculator is an essential tool for estimating the volume of wood required for various projects. Whether you're planning a deck, cabinet, or custom furniture, accurately calculating board footage ensures that you purchase just the right amount of lumber.

What is a Board Foot?

A board foot is a unit of measurement in lumber used to estimate the volume of wood. It represents one square foot of lumber that is one inch thick. The formula for calculating board feet is straightforward:

Board Foot Formula:

Board Feet (BF) = ( Thickness(in) × Width(in) × Length (ft) ) / 12

Why Use Board Feet?

Lumberyards and suppliers sell hardwood lumber based on board feet. Knowing how to calculate this ensures accurate pricing and helps avoid waste.

How to Calculate Board Feet

To calculate board feet, follow these steps:

  1. Measure the Dimensions
    • Record the thickness, width, and length of the lumber in inches and feet.
  2. Use the Formula
    • Multiply the dimensions together and divide by 12 to get the total board feet.
  3. Account for Multiple Pieces
    • Multiply the board footage of a single piece by the number of pieces needed.

Example:

For a 2×4×8 piece of lumber:

Board Feet = (2x4x8) / 12 = 5.33 BF

Common Lumber Applications and Their Calculations

Deck Building

Deck boards are usually calculated in large quantities. Measure the total area and thickness to determine board footage for the entire project.

Cabinetry

Cabinets require precision. Ensure each piece of hardwood lumber is accurately measured for thickness, width, and length to avoid shortages.

Custom Furniture

Unique designs demand flexibility in dimensions. Use the board foot calculator to quickly estimate the lumber volume for various pieces.

FAQ

How Many Board Feet is a 2x4x8?

A 2x4x8 piece of lumber equals 5.33 board feet.

How Many Board Feet is 2x3x10?

A 2x3x10 board equals 5 board feet.

What is the Difference Between LF and BF?

  • LF (Linear Feet): Measures the length of lumber only.
  • BF (Board Feet): Includes thickness, width, and length to calculate volume.

What is the Length of 1 Board Foot?

The length varies depending on the board's width and thickness. For a 1-inch-thick, 12-inch-wide board, the length is 1 foot.

How Much Area is 200 Board Feet?

It depends on the board's dimensions. For example, a 1-inch-thick board with a width of 12 inches would cover 200 square feet.

How Many Board Feet is a 4x4?

For an 8-foot-long 4x4, the calculation is:

Board Feet = (4x4x8)/12 = 10.67 BF

How Much is One Board?

The price depends on the wood species, quality, and size. Use the board foot calculator to estimate costs based on board footage.

How to Calculate Linear Feet?

Measure the total length of all boards without considering width or thickness.
