This calculator requires the use of Javascript enabled and capable browsers. This calculator is designed to provide approximate weights for many different wood varieties, but seasoned with the expected and logical caveats. Wood varies considerably in weight based on numerous factors, including area, climatic conditions, cutting time, age and many more condition. Our objective is to give a reasonably good approximation. Enter the number of boardfeet of lumber, then select the variety. Click on Calculate for the resulting approximate green weight. To calculate and total quantities of specific sizes of boards, use our Boardfeet Accumulator. To calculate random boards of various sizes (by definition only) defining width, depth, quantity as well as length, use our Boardfeet Calculator.
