Inside someone tree, the variation in wood density is frequently as excellent as or even larger than that involving various trees (Timell 1986).[23] Variation of specific gravity inside the bole of the tree can occur in possibly the horizontal or vertical direction.

The density of the sample of wood can be appraised visually by observing the width (thickness) of expansion rings and also the here proportion of latewood. Usually, latewood, on account of its thicker mobile partitions and smaller sized cell cavities, is denser than earlywood, and with raising ring width its proportion decreases in softwoods and will increase in ring-porous hardwoods.
