Paper analyse qualitative and quantitative yield of beech wood in timber conversion and processing process. Is necessary to evaluate the beech structural timber for application in timber constructions not only according to mechanical properties, but also according to the technological processing. Grading parameters, mainly edgewise and flat wise shrinkage affect its qualitative yield. Tested material consist of 15 tree trunks (21 m-3 ), each was cut into two logs (total 30 logs) further 247 boards (7,4 m-3 ). After processing by planning was boards adjusted to dimension of 50/150 x 3100 mm. Quantitative yield of trunks/boards was 35%. In next step was boards qualitatively graded according to STN 49 1531/Z1, 2006. Of the total number of boards n = 247,118 boards were proved as structural timber (3,5 m-3 ). Qualitative yield of boards/structural timber was 48%. Total yield of trunks/structural timber was 17%.
