Nail Shapes Explained: Square, Round, Oval, Almond, Stiletto, Coffin, and Squoval

Nail shape changes the whole look of a manicure independent of color or nail art. Here's how the most common shapes are filed and what makes each one distinct.

Square

Filed straight across the top with sharp, defined corners. A classic, low-maintenance shape that works well with shorter to medium lengths and tends to be more resistant to chipping at the edges than rounder shapes.

Round

Follows the natural curve of the fingertip, with softly rounded corners and little length beyond the fingertip. Low-maintenance and generally considered the most practical everyday shape, especially for shorter nails.

Oval

An elongated, rounded shape with no flat top, tapering gently like an egg. Often chosen to visually lengthen the fingers, and generally requires slightly longer nail length than round to achieve properly.

Almond

Tapers inward toward a rounded (not pointed) tip, resembling an almond's shape. A popular middle ground between the softness of oval and the dramatic taper of stiletto.

Stiletto

Tapers to a sharp, narrow point, requiring significant length and, because of the thin tip, more prone to breaking than other shapes. Favored for a bold, dramatic look rather than everyday durability.

Coffin (ballerina)

Tapered sides like almond or stiletto but with a flat, squared-off tip instead of a point β€” named for its resemblance to a coffin or a ballet slipper's shape. Requires longer length and is a popular base shape for elaborate nail art.

Squoval

A hybrid of square and oval β€” squared-off but with the sharp corners softened and rounded. Combines square's flat top with a more comfortable, less catch-prone edge, and is often recommended for people whose nails tend to break at sharp corners.

Shape interacts with nail bed width and length

Narrower nail beds can look visually widened by rounder shapes like round or oval, while wider nail beds are often visually narrowed by tapering shapes like almond or coffin. Shape also has to work with your natural nail length and strength β€” very tapered shapes (stiletto, coffin) generally need more length and more reinforcement (gel or acrylic) to hold up.

Filing direction affects how a shape holds up

Filing in one consistent direction, rather than sawing back and forth, reduces splitting and helps the shape stay defined longer regardless of which shape you choose. Sharper-cornered shapes like square and stiletto are more prone to snagging and chipping at the corner or tip specifically, which is part of why rounder shapes are often recommended for very active hands.

Frequently Asked Questions

What's the difference between almond and stiletto shapes?

Both taper inward from the sides, but almond ends in a rounded tip while stiletto comes to a sharp point β€” almond is generally considered a more everyday-wearable version of the same tapered silhouette.

Which nail shape is the most durable for daily activities?

Square and round shapes are generally the most chip- and break-resistant for everyday use, since they have shorter working length and don't rely on a thin, tapered tip the way stiletto or coffin shapes do.
