About Standing Tree Volume and Quarter-Saw Yield
This dual-mode tool handles two related calculations. Mode 1: estimate merchantable volume of standing trees from DBH and height using IS 4213:2013 India for plantation valuation and timber permits. Mode 2: predict quarter-sawn lumber yield percentage from round log dimensions for premium timber applications.

Formulas
IS 4213 India: V = (pi/4) x DBH^2 x H x f DBH in metres, H in metresBasal Area: BA = pi x (DBH/200)^2 m2, DBH in cmQS boards per quarter = floor(R x 10 / (thickness + kerf))
FAQ
What is Form Factor in IS 4213?
Form factor f accounts for tree taper - trees are not cylinders. IS 4213:2013 provides species values: Teak = 0.55-0.60, Sal = 0.53-0.57, Eucalyptus = 0.48-0.52. Using wrong form factor is the most common error in standing tree valuation.
Why pay premium for quarter-sawn lumber?
Quarter-sawn boards expand and shrink 50-60% less in width vs flat-sawn, show beautiful ray fleck patterns in oak, are more wear-resistant in flooring, and hold finish better. Premium is 20-50% over flat-sawn.
