Actual Size of Dimensional Lumber

What Actual Size of Dimensional Lumber is for
Actual Size of Dimensional Lumber is the page to open when you need actual size of dimensional lumber from measurements you already have. It belongs with the other construction calculators because that is the work this arithmetic supports. Lumber quantity in board feet is the board feet. Type the entries first. The result stays hidden until you press Calculate, so a half-finished form never flashes a number you might mistake for the answer.
How to fill in this calculator
This page is the written companion for the tool. Where the form asks for a measurement, enter it in the unit printed on that field, then press Calculate. Nothing is computed while you are still typing.
The formula in plain language
Box volume is length times width times height. Dimensional weight for many parcel carriers divides that cubic-inch volume by 139 to estimate a billable weight in pounds. Cubic meters are the same edges measured in meters and multiplied. Freight class is estimated from density in pounds per cubic foot. A denser crate falls into a lower class.
A worked example
An 18 by 18 by 16 inch carton is 5,184 cubic inches, or 3.0 cubic feet. Divided by 139, the dimensional weight is 37.3 pounds. If the real weight is 22 pounds, the carrier bills the 37.
Boards, sheets, and trim are ordered from the same takeoff. This actual size of dimensional lumber count should agree with feet and inches calculator and how much plywood weighs.
Mistakes that move the answer
- Measure the outermost carton, including bulges.
- The divisor 139 is a common domestic rule. A carrier can publish a different one.
How to check the result
After Calculate shows the actual size of dimensional lumber result, redo the last operation with a pencil using the rounded figures on the screen. Matching that check means the inputs were read correctly. If you edit a label or a sentence in this HTML file, reload the page. The form and this article both live in the file, so the edit is what visitors will read.
