## Quick Answer

Calculate the volume of lumber in board feet. Enter the thickness, width, length, and quantity to find the volume and total cost.

## Definition

A board foot calculator is a specialized wood volume utility used by woodworkers, contractors, and lumberyards to determine the volume of rough lumber. A board foot is a standard unit of volume equivalent to a board that is twelve inches wide, twelve inches long, and one inch thick. The calculator multiplies the lumber's thickness in inches, width in inches, and length in feet, dividing the result by twelve to find the total board feet. It can also estimate total material costs based on a specified price per board foot.

## How to Use

1. **Input board dimensions** — Enter the thickness and width of the boards in inches, and the length in feet.
2. **Set quantity and price (optional)** — Type the number of boards you need and enter the cost per board foot to calculate pricing.
3. **Read the total volume** — View the calculated board feet and the estimated cost for your lumber order.
