Editor's note
The shape you file is the most permanent decision you make at the nail table. Direction matters more than speed. Filing back and forth across the free edge creates micro-tears that split within days. Filing in one direction, from the outer edge toward centre, builds a closed edge that holds through growth. Grit selection is the second variable most people ignore: 180 grit for natural nails, 100 for gel overlays.
Manicure steps
What nail shape actually means
Nail shape refers to the silhouette of the free edge — the portion of the nail that extends beyond the fingertip. It's set entirely by how and where you file. The shape you choose changes the apparent length of the finger, the perceived width of the nail plate, and how the hand reads at rest.
Myth, meet fact
- Myth: Filing back and forth is faster and just as good. Fact: Filing in both directions creates micro-fractures. Single-direction filing produces a closed, sealed edge that resists splitting.
- Myth: Any nail file works for any nail. Fact: Grit matters. 180-grit for natural nails, 100-grit for gel or acrylic. Low grit on thin natural nails removes too much material.
- Myth: The shape doesn't change once polish is on. Fact: A poorly executed shape reads through three layers of colour and a top coat. Filing is the foundation.

Shape, by hand type
Square for structure and long nail beds. Round for short nails and low-maintenance wear. Oval for most hand types — the versatile elongating shape. Almond for slender appearance on medium to long nails. Coffin for graphic silhouette with length. Stiletto for maximum drama with overlay support.
