When applying a nail tip to the natural nail, what is important for determining the correct size?

The key aspect for determining the correct size when applying a nail tip is that it must fit sidewall to sidewall. This ensures that the nail tip adheres correctly to the natural nail without any gaps that could lead to lifting or separation. A sidewall-to-sidewall fit provides a secure base for the nail enhancement, allowing for a natural appearance and proper support.

When the tip fits snugly from one sidewall of the natural nail to the other, it minimizes the risk of future problems, such as breakage or discomfort. A good fit is essential for the longevity of the nail enhancement and contributes to the overall aesthetic of the manicure.

Although having the tip align properly with the cuticle edge is important, it is not as critical as ensuring that the sides fit well. If the sides are too wide or too narrow, it can create issues, regardless of how well it aligns with the cuticle.
