Aim of this study, is to determine the best form factor formula for Oriental beech (Fagus orientalis Lipsky) the important forest trees of Turkey. The data obtained from sample trees taken from generally even- aged, middle aged (40- 60 years), normal closed, pure and natural stands. Form factors of trees were calculated for 50 Oriental beech sample trees in Black Sea region of Turkey. As a consequent, each tree’s volume was precisely calculated as the real volume. Next, the breast height form coefficient was calculated and its average was statistically compared to the averages of absolute (f0), natural (f0.1), artificial (f0.5) and Hohenadl’s (fh) form coefficients using pair sample t-test. Results showed that there is significant difference between the averages of absolute, natural, artificial and Hohenadl’s form coefficient. As a result, stem form coefficients are not capable to replace the breast height form coefficient of Oriental beech trees over the study area.
