Square Nails
The square nail shape is pretty self-explanatory. Square nails are square—they’re flat on top with straight, sharp corners. They neither flare out nor taper in and are a popular shape for those with short nails or long, narrow nail beds.
Squoval Nails
Square oval or squoval nails are perfect if you’re into the flat edge of the square but hate sharp corners. Squoval is your best option. This universally flattering shape has softened corners for the best of both worlds.
Oval Nails
Yes, round nails are different from oval ones. Here’s how: Oval nails are filed down on the sides in addition to the tips. The curvature is more extreme, so it tends to make fingers look more slender.
Round Nails
The classic round shape is another favorite for those who prefer to keep their nails clipped short. Like square nails, round nails start with straight sides but curve at the edges to follow the natural shape of the fingertip.
Almond Nails
Like oval nails, almond nails are filed along the sides. The nail wall is tapered to end in a round peak, similar to the shape of an actual almond. Natural nails are often too weak to hold this structure on their own, so most almond manicures are reinforced with gel or acyclic.
Coffin Nails
Arrowhead nails are a less severe version of a stiletto nail. The point is shorter and softer.
Stiletto Nails
Stiletto nails are all about the drama. Shaping this spiked look starts off the same as it’s nuttier counterpart, the almond, but ends at a much sharper point with a wider base. (Stiletto nails are also perfect for ice cream cone nail art, as seen below.)’
