Grain: A term that can mean many things. In the context of this website it refers to a) the general arrangement of wood fibers (see straight grain, spiral grain, interlocked grain) and b) the contrast between earlywood and latewood cells on the tangential and/or radial face.( see even grain, intermediate grain, coarse grain)Top
Interlocked grain: A wood grain that alternates repeatedly from the left and the right of longitudinal. Wood that has an interlocked grain are very difficult to split.
Spiral grain: Grain which deviates from longitudinal orientation. Grain arranged either to the left or right of longitudinal.

Straight grain: Wood grain whereby the cells are arranged longitudinally in the tree.
Even grained: Wood grain whereby there is little contrast on the tangential or radial face between earlywood and latewood. The wood appears to have a fairly consistent, single color to it.
Intermediate grain: Wood grain whereby the contrast between earlywood and latewood is intermediate to even grain and uneven grained wood.
Uneven-grained: Wood grain whereby there is significant contrast on the tangential or radial face between the earlywood and latewood. Wood grain showing a distinct difference in appearance between springwood and summerwood. Examples are ring-porous hardwoods such as oak, and softwoods such as yellow pine that have soft springwood and hard, dense summerwood.
