Board Foot Formula:
From: | To: |
Definition: This calculator estimates the volume of lumber in board feet based on the thickness, width, and length of wood pieces.
Purpose: It helps woodworkers, carpenters, and DIYers determine how much lumber is needed for projects and estimate material costs.
The calculator uses the formula:
Where:
Explanation: One board foot equals 144 cubic inches (12" × 12" × 1"), so we divide the product of dimensions by 12 to convert to board feet.
Details: Accurate board foot calculations ensure proper material estimation, cost control, and project planning in woodworking and construction.
Tips: Enter the thickness and width in inches, length in feet. All values must be > 0. The result shows total board feet.
Q1: What exactly is a board foot?
A: A board foot is a volume measurement equal to 1 foot long × 1 foot wide × 1 inch thick (or equivalent).
Q2: How do I calculate board feet for multiple pieces?
A: Calculate board feet for one piece, then multiply by the number of identical pieces needed.
Q3: Does this work for metric measurements?
A: No, this calculator uses imperial units. Convert metric to inches/feet first.
Q4: How does thickness affect board feet?
A: Thicker boards yield more board feet per piece since volume increases with thickness.
Q5: Should I add extra for waste?
A: Yes, consider adding 10-20% to the calculated amount for cutting waste and defects.
