For the elaboration of two-inlet volume tables for Douglas fir (Pseudotsuga menziesii), material collected in the Podrinjsko-Kolubarski region in Serbia (Yugoslavia) was used. 450 model trees were used as a basis. Comparison of the original and the table data has shown an average difference of 1.86%, the table volume being for that percent smaller. For the comparison of the tables two-inlet volume tables for Douglas fir made by Hauser (1956) and Gurgiu et al. (1972) were used. The volumes of the tree diameter of 10 cm and the height of 10 m, then the diameter of 15 cm and the height of 15 m, 20 cm diameter and 15 m height, 24 cm diameter and 20 m height were compared.
