Nail shapes: a visual comparison guide

A nail shape is named for the outline of the free edge, the part of the nail that extends past the fingertip. Two features separate one shape from another: how the sidewalls run (straight, tapering inward or flaring outward) and how the tip ends (curved, flat or pointed). The shapes covered here are rounded, oval and almond, square, squoval, coffin (also called ballerina), stiletto (also called pointed), and duck (also called flare). Nail wraps often appear in the same searches but describe a covering applied to the nail, not an outline, so they are handled separately below.

Nail shapes chart

Shape | Sidewalls | Tip | Overall silhouette

Rounded | Straight, following the nail bed | Gently curved, mirroring the fingertip | Soft and close to the natural nail

Oval | Taper gently | Evenly curved | Elongated egg outline

Almond | Taper more steeply | Narrow, softly rounded peak | Slim outline shaped like an almond

Square | Straight and parallel | Flat, with sharp corners | Crisp and boxy

Squoval | Straight and parallel | Flat, with softened corners | Square outline with rounded edges

Coffin / ballerina | Taper inward | Cut flat across the narrowed end | Tapered outline with a squared-off tip

Stiletto / pointed | Taper sharply | Comes to a point | Long, sharp, dramatic outline

Duck / flare | Widen toward the tip | Broad and flat or gently curved | Fan-like, wider at the tip than at the base

How to identify a shape in a reference photo

• Look at the sidewalls first: parallel sidewalls point to rounded, square or squoval; inward-tapering sidewalls point to oval, almond, coffin or stiletto; outward-flaring sidewalls point to duck.
• Then look at the tip: a point means stiletto; a flat end on a tapered nail means coffin; a flat end on a straight nail means square or squoval; a curve means rounded, oval or almond.
• Check the corners on flat tips: sharp corners mean square, softened corners mean squoval.
• Compare the narrowest point to the base: if the tip is noticeably narrower, the nail belongs to the tapered family; if it is wider, it is a flare.
• Note the length separately from the shape, since the same outline can be filed short or long.

Each shape up close

Rounded

Rounded nails keep straight sidewalls and finish with a curve that echoes the shape of the fingertip. Visually, it is the least dramatic outline and reads as close to a natural, unfiled nail.

Oval and almond

Oval and almond are often grouped together because both taper toward a curved tip. The difference is degree: an oval tapers gently into a wide, even curve, while an almond narrows more steeply to a slimmer, softly rounded peak. In photos, an almond looks more elongated and closer to a point without actually becoming one.

Square

Square nails have parallel sidewalls and a tip filed straight across with crisp corners. The flat edge creates a strong horizontal line at the end of the nail, which gives the shape a clean, graphic look.

Squoval

Squoval is a blend of square and oval: the outline stays straight-sided with a flat tip, but the corners are rounded off. The result looks less sharp than a square while still reading as more structured than a rounded nail.

Coffin or ballerina

Coffin nails taper inward like an almond but are cut flat at the narrowed end instead of being rounded or pointed. Both names describe the silhouette: the outline resembles a coffin, and the flat narrowed tip is compared to a ballet pointe shoe.

Stiletto or pointed

Stiletto nails taper sharply from the sidewalls to a single point. It is the most dramatic of the tapered shapes, and the point is what distinguishes it from an almond.

Duck or flare

Duck nails do the opposite of the tapered shapes: the sidewalls widen as they extend, so the tip is broader than the base. The fan-like outline is easy to spot in photos and gives the shape a bold, statement look.

Comparing shapes by design priority

The points below are aesthetic observations about how each outline looks, not rules about who a shape suits. Personal preference should decide the final choice.

• If you want the most natural look, rounded and oval stay closest to the outline of an unfiled nail.
• If you want clean, geometric lines, square gives the sharpest edge and squoval softens it slightly.
• If you want an elongated silhouette, almond, coffin and stiletto all taper, with stiletto the most extreme and almond the softest.
• If you want a flat tip with a slimmer outline, coffin combines a taper with a squared-off end.
• If you want a bold, unconventional outline, duck stands out because it widens instead of narrowing.
• If you want a broad canvas for nail art, shapes with wider tips, such as square, squoval and duck, leave more surface near the free edge; tapered shapes concentrate the design toward the center of the nail.

Shape and length together

Length and shape are separate choices, but some outlines need length to read clearly. A taper or a flare only becomes visible once there is enough free edge to shape, so coffin, stiletto and duck are usually shown at longer lengths in reference photos. Rounded, square and squoval keep their character even when filed short, which is why they appear often in short nail inspiration. Oval and almond sit in between: a short oval reads clearly, while an almond looks more defined with extra length.

Readers with wider fingers or nail beds often ask which shape to pick. The supplied sources do not support any rule on this. As a purely visual observation, tapered outlines draw the eye along the length of the nail, while flat, wide tips emphasize width, but trying references against your own hands is more reliable than any general guideline.

Where nail wraps fit

Nail wraps show up alongside shape names in searches, but a wrap is something applied to the nail rather than an outline the nail is filed into. Treat it as a separate decision from choosing rounded, square, coffin or any other shape.

What this guide does not cover

• Durability and breakage: the supplied evidence does not compare how well different shapes hold up, so no claims are made here.
• Acrylic and other enhancements: no material-specific evidence was supplied about which shapes require extensions, how they are built or what upkeep they need. Ask your nail technician about these details.
• Trends for 2026: no trend data was supplied, so this guide does not rank shapes by popularity.
• Measurements: the chart describes outlines only; no standard lengths or dimensions were supplied.
