How Big is Your Tree? Estimating Board Feet in a Tree
Montana State University Doc, 2013. 2 pages “The forester measures the tree diameter and the tree height. From
these two measurements a forester can determine how much lumber is in a tree, and thereby predict how much wood is in a particular timber area…”

Measuring Standing Trees
Ohio State University Extension. 2016 & 2024.
“Woodland owners often need to measure the merchantable board-foot content (termed “volume”) of certain trees in their woodland. In order to sell timber, for example, an estimate is needed of the quantity to be sold. If trees are to be cut to provide lumber, an estimate of volume is needed to determine what size and how many trees to cut. Using the methods described in this article, a woodland owner can estimate the board-foot volume in one or several trees.”

Log Rule Board Feet Calculator
PK on dqydj.com “On this page is a board foot log rule calculator, which will estimate the board foot yield of a log using the Doyle or Scribner log scale rules, or the International log rule with a 1/4″ or 1/8″ kerf. It can also estimate the yield of standing trees using the Wiant and Castaneda adaptations of the Doyle, Scribner, and International 1/4″ rule.”
