Which nail shape is considered best to prevent chipping or breaking?

The round nail shape is considered the best for preventing chipping or breaking due to its smooth, curved edges. This design minimizes stress on the tips of the nails as it evenly distributes pressure across the surface when reacting to everyday activities.

Round-shaped nails can reduce the likelihood of snagging, as their softer contours help them slide over surfaces without catching. Additionally, this shape tends to be more natural and adaptable, allowing the nails to follow the natural shape of the fingertip.

In contrast, other shapes, such as square or almond, may have sharper edges which can lead to areas that are more prone to breakage, especially if subjected to strain or impact. Therefore, the round nail shape provides a more resilient option for maintaining nail integrity.
