Board Feet Calculator – Quick Lumber Measurement

Use this board feet calculator tool to accurately measure the volume of lumber for your woodworking project.

Board Feet Calculator

This board feet calculator helps you determine the amount of lumber you have in board feet, which is a standard unit of measurement for lumber in North America. Simply enter the dimensions of the lumber and the quantity, then click “Calculate.”

How to Use the Calculator

  • Length: Enter the length of the board in feet.
  • Width: Enter the width of the board in inches.
  • Thickness: Enter the thickness of the board in inches.
  • Quantity: Enter the number of boards.

Once you have entered all the required values, press the “Calculate” button. The result will be displayed in board feet.

How It Calculates

The calculator uses the formula for board feet calculation:

Board Feet = (Length in feet * Width in inches * Thickness in inches * Quantity) / 144

This formula converts the dimensions into a standard unit of board feet.


This calculator is designed for basic calculations and may not account for variations in wood types, moisture content, or other factors that might affect the accuracy of the measurements. Always consult with a professional for more precise calculations.

Use Cases for This Calculator

Calculating Board Feet for a Single Piece of Wood

Input the thickness, width, and length of a single piece of wood to determine the board feet. The calculator will multiply the dimensions together and divide by 144 to give you the total board feet.

Estimating Total Board Feet for Multiple Pieces of Wood

If you have several pieces of wood with different measurements, enter each piece’s dimensions separately to calculate the total board feet. The calculator will sum up the individual board feet to give you the overall total.

Calculating Board Feet for Imperfect or Oddly Shaped Pieces

Even if your wood pieces have irregular shapes or dimensions, the calculator can still determine the board feet accurately. Input the measurements of the widest points for width and length to get the correct board feet calculation.

Converting Inches to Feet Before Calculating Board Feet

If you’re used to working with measurements in inches, no worries. Input the dimensions in inches, and the calculator will automatically convert them to feet before calculating the board feet.

Adjusting Board Feet Calculation for Varying Thickness Options

For wood pieces with different thickness options, select the appropriate thickness measurement from the dropdown menu before inputting the width and length. The calculator will adjust the board feet calculation accordingly.

Calculating Board Feet for Specialized Wood Cuts

Whether you’re dealing with rough sawn, quartersawn, or live edge wood, the calculator can handle it all. Simply input the specific measurements for width, length, and thickness to get the accurate board feet calculation.

Determining Board Feet for Both Standard and Metric Measurements

Whether you prefer working with feet and inches or centimeters and millimeters, the calculator supports both types of measurements. Input the dimensions in your preferred format, and the calculator will provide the board feet accordingly.

Calculating Waste or Offcuts in Board Feet

If you have leftover pieces or offcuts from previous projects, input their dimensions to calculate the board feet for waste material. This feature helps you estimate the usable wood left for future projects accurately.

Sharing Board Feet Calculation Results with Colleagues or Clients

After obtaining the board feet calculation, easily share the results with your colleagues or clients by copying the total board feet value. This feature ensures seamless communication and collaboration in woodworking projects.

Using the Board Feet Calculator for Various Woodworking Projects

Whether you’re working on furniture, cabinets, flooring, or any woodworking project requiring accurate wood measurements, the board feet calculator is your go-to tool. It simplifies the calculation process, saving you time and effort in your woodworking endeavors.
