In recent years, the global economy has been shifting from manufacturing to service, and especially in the beauty industry, interest is increasing in the nail industry as well as in the theoretical field. With the introduction of nail art in Korea, it entered the mid-2000s, and even the self-nail group appeared. In addition, as the demand for online shopping malls and offline shopping malls surges, more and more consumers enjoy self-nailing. In addition, as it was revitalized around women in their 20s and 30s, looking at the tendency of domestic women in their 30s, the highest proportion of consumers who thought they were the consumer was the highest. In the meantime, the previous study suggests measurements of fingernail size and tip size, but the results of the previous study have only performed direct measurement. Therefore, in this study, direct measurement and 3D scanner measurement were measured for women in their 30s among domestic women. The purpose of this study is to compare and analyze the nail size of 30 nails, and then to suggest the size of the nail tip. In addition, it is of great significance that the measurement was attempted using a 3D scanner measurement method.
