Deal is an obsolete unit of measurement formerly used in the UK and US to measure what is today described as "Dimension Lumber". From the late 18th to the early 20th centuries, the term "deal board" referred to rough sawn Spruce or Pine planks two to three inches thick (sometimes thicker), up to 12" wide and 12 to 14 feet long. These were often re-sawn into smaller dimensions by the end-user for use in Wood Framing, Cooperage and Furniture making. They were traded as a maritime commodity. The term "Deal" is also used to refer to wood from Fir or Pine trees
