Quarter sawn lumber refers to the angle at which the tree's growth rings intersect the face of the sawn board. Although there are differing opinions on the term, fully quarter sawn lumber is generally defined as growth rings that are 80 to 90 degrees to the face of the board.

Rift sawn lumber is usually used with oak to avoid the flecks that are common in the species. The annular rings or a rift sawn board are about 30-60 degrees to the face of the board, but 45 degrees is the most optimum
