Therefore, this study aims to provide basic data for developing a nail tip size system for Korean consumers by measuring and analyzing home nail products available in the market. To analyze the sizes of home nail tips, the authors examined the nail tip products available online. The authors measure the size directly on 11 points, including vertical length, horizontal width, side angle, thickness, and weight. The results are as follows. comparing the sizes among the home nail tips measured in this study showed that the vertical length was longest among Korean products followed by Chinese and US products, and the Korean products showed the largest deviation between the different sizes. The horizontal width was the widest in the mid-nail tips compared to the upper nail and lower nail. comparison of the size charts presented on the websites selling the products in this study showed that, among the US products, the vertical length was the longest for the stiletto type. Comparing the standard measurement size presented on the websites and the actual measurement of the home nail tips suggests that, although it is difficult to determine whether the sizes are similar simply based on vertical length and horizontal width, compared to the Korean products, the US and Chinese branded products had smaller differences and the size suitability US was highest among the Korea, China, US. This study suggests the development of a size system for self-applied nail tips products suitable for Korean nail sizes.
