The objective of this study was to determine Holstein Cattle body measurements using digital imaging DIPM methods. The ratios were calculated by dividing each measurement by another and the relationship between the ratios and the output characteristics were evaluated. For this reason, the body measurements of the 198 heads of Holstein cattle breed dairy cows were calculated by the Set Object Video System (SOVS) process. The ratios were calculated by dividing each body measurement to another then the relationship between these ratios and the characteristics including the daily average milk yield (DAMY), the number of inseminations per calving (NIPC), the age at insemination (AFI) and the age at first calving (AFC) were evaluated. The relationship between DAMY, NIPC, AFI, AFC and body measurements were; withers height (WH), back height (BH), rump height (RH), pin bone height (PBH) ), chest depth (CD), body length (BL), trunk length (TL), body area (BA) and body perimeter (BP) was low, negative and not statistical significantly (p>0.05). The highest R2 measured for DAMY by WH (0.389 (p
