Lineal Foot (“LF”)

Some types of wood are sold at a specific width and “per lineal foot” of length. This is in contrast to “per board foot,” which is a volume measure, and can be used to tally lumber of random widths. Example: If a 1 in. X 4 in. X 10 ft. board is priced by the

Board Foot (“BF” or “Bd. Ft.”)

“BF” is a volume measure of lumber. It is calculated using the dimensions of the lumber in the rough. This means that it uses the measurement of a board prior to planing or the application of a straight-line rip. How to Calculate: Thickness (in inches) X Width (in inches) X Length (in feet)Then divide the

Quarter Measure

Lumber size is often referred to as 4/4 (pronounced FOUR-QUARTER), 5/4 (FIVE-QUARTER), 6/4 (SIX-QUARTER), etc. This refers to the thickness of the lumber when it is first sawn and in its rough dimensions. 4/4 lumber is sawn in the rough to a full 1 inch. The size increases in 1/4″ increments. 5/4 lumber is sawn

Rough (“RGH”)

“RGH” indicates that the specified material is being sold as it came off the saw. It is in its “rough” state. This material is not planer-finished and will have no jointed edges.

Surfaced Three Sides (“S3S”)

The abbreviation “S3S” is a description of surface finish, usually pertaining to hardwood species. It stands for “Surfaced Three Sides”, which, as used in Goosebay’s hardwood lumber descriptions, indicates that two faces have been planed, and one edge has been processed with a “straight-line” rip saw, rendering the edge straight and smooth. The other edge

Dressed Four Sides (“D4S”)

“D4S” indicates that the materials have been surfaced on all four sides. NOTE: Dressing will change the actual size of a rough cut measurement. For example, a 4 X 4 piece of lumber dressed on four sides will have an actual measurement of approximately 3.5 X 3.5.

Quarter Sawn Lumber

Quarter sawn lumber has been cut through the heart of a log and thus the annular rings are perpendicular or 90º to the face of the board.  The result is an extremely stable board and can produce spectacular grain patterns  (i.e. Ribbon Stripe Sapele or Leopardwood).  This is usually more expensive lumber since only a

Rift Sawn Lumber

A board sawn through the heart of a log is called quarter sawn  and the annular rings are 90º-60ºto the face, As the log is further sawn, the ring- to-face  angle will  progressively flatten.  A rift sawn, or rift cut,  board has an annular ring  angle to the face of 60º-30 º.  Rift sawn boards

Flat Sawn Lumber

A board sawn through the heart of a log is called quarter sawn  and the annular rings are 90º to 60ºto the face.   As the log is further sawn, the ring- to-face  angle will  progressively flatten.   A rift sawn board has an annular ring  angle to the face of 60º to 30 º. A
