In professional salons, clients constantly debate between almond and oval manicures. While both shapes belong to the curved, non-square family, their underlying geometric architecture is fundamentally distinct:
| Architectural Trait | Classic Oval Shape | Tapered Almond Shape |
|---|---|---|
| Sidewall Trajectory | Remains straight and parallel for 3mm before curving | Angles inward immediately from the stress groove |
| Apex / Tip Geometry | Smooth, continuous semi-circular dome | Softly pointed apex with rounded peak |
| Minimum Free-Edge Length | 2mm – 3mm (Can be worn short) | 5mm – 8mm (Requires medium length) |
| Keratin Lateral Strength | Maximum natural strength (95%) | Moderate strength (Requires overlay) |
The oval shape preserves the lateral keratin walls, curving only at the distal free edge. Almond, by contrast, requires filing away the outer corners and tapering the sidewalls inward, concentrating pressure into a narrower tip.
