Finding a flattering shape is generally dictated by the length and width of your fingers and nail beds, but consider your personal style, too. If you prefer an edgier look, longer, angular nails will add to this. Those with a more understated style might choose to go for a shorter, neater nail featuring softer curves.
When looking at the shape of your hands and nails, you'll likely fit in to one of four categories. Generally, longer fingers with slim nail beds suit square or 'squoval' (square with a slightly rounded oval edge) shapes, as this adds an angular touch to streamlined hands. Long, wide fingers will find balance with elongated almond or oval shapes, while short, wide fingers will find the curves of round or oval nails the most flattering. Lastly, short, slim fingers tend to suit shorter styles, but can pull off most shapes.
