Anthropometric measurements of the breast play a guiding role in surgical planning. In our study, it was aimed to determine the normal shape and size of the breast by taking measurements in young women who did not experience pregnancy or surgery and comparing them with the results of other studies. The breast parameters of 88 women aged between 18 to 30 years old, with a normal body mass index, with no history of previous pregnancy, surgery or rapid weight gain were measured. The measured parameters were age, body mass index, cup size, distance between nipple and suprasternal notch, distance between both nipples, distance between midclavicular point and nipple, distance between midclavicular point and upper border of the breast, the distance between the midaxillary line and nipple, the distance between the nipple and inframammarian fold, the projection of the breast, the projection of the nipple and the chest circumference under the breast. The mean values were determined and the correlation between the parameters was evaluated statistically. A significant correlation was found between cup size and all parameters except for the chest circumference and nipple projection. The distance between the midclavicular point and upper border of the breast was found correlated with the cup size. In addition, a significant correlation was found between body mass index and all other parameters. This study revealed the average breast size and measurements of women in Turkey. It can be useful to guide for both reconstructive and aesthetic procedures of the breast.
