1Oval Nails
@lolo.naileditThe oval nail shape is deceivingly difficult to execute, since the slightly tapered end can easily veer into almond or round territory if you file too heavily or not enough. “It takes patience to file an oval shape—so go slow,” says Miss Pop.
Who it's best for: This shape works best with a longer nail that at least goes above your finger tip, or else you can opt for extensions or acrylics. “If you flip your hand palm side up and can see the tips of your nails, then you can definitely create this shape,” says Miss Pop.
2Square Nails
@raelondonnailsArguably the easiest shape to create, square edges are achieved by simply filing back and forth across the top of your nail. Keep in mind that the corners tend to get a little jagged though, so prepare for regular filing to keep them smooth. “When filing the sides, make sure to keep the file perpendicular to your nail, and be careful not to apply too much pressure or the edge will take on a concave U shape versus staying straight and boxy,” says Choi.
Who it's best for: Square edges work on both natural and fake nails, but “it tends to look best on those with long, narrow nail beds,” says Choi.

3Squoval Nails
@raelondonnails“This square-meets-oval hybrid is my favorite because anyone can wear it—whether you have short, medium, or long nails—plus, it’s modern and soft,” says Choi. The catch? It’s easy to mess up. “People make the mistake of filing straight across the top and or curving the corners too much,” she explains. Instead, create a subtle arc at your tips and then connect the sides so there’s a natural taper.
Who it's best for: Like Choi said, it suits any nail length, so get ready to give it a go ASAP.
4Almond Nails
@samrosenailsUnlike an oval nail, which has only slightly tapered sides, this nail shape is more extreme. “It’s very glamorous,” says Choi. “It gets its name because the entire nail looks like an almond in that it’s elongated at the tip with a round base.”
Who it's best for: The almond shape looks best on medium to long nails, since plenty of length is required for it to be noticeable, says Choi.

5Rounded Tapered Nails
@overgloweditNow, this finger-elongating shape is slightly in between a curved oval and a pointed almond. To achieve rounded tapered nails, start by filing the sides of the nail and tapering them toward the tip, then round off the edges for a smooth and softer finish.
Who it's best for: You'll need some length for rounded tapered nails, so anyone with mid-length or long nails, will be able to execute this with ease. Or with extensions or acrylics, of course.
6Round Nails
@nails.byliz“This is a very soft, natural look that’s easy to maintain—even if you break a nail, you can sacrifice a little length and still keep the shape,” says Miss Pop. Move a nail file “side to side to create the gentle arc,” she says, "almost like you’re mimicking the same curve of your cuticles."
Who it's best for: “It works best on nails that are short or that have grown slightly over your fingertips,” adds Miss Pop. Translation: This is a great go-to for people who can’t grow their nails super long.

7Coffin Nails
@jenny.jennysCelebs like Kylie Jenner and Khloé Kardashian are major fans of the coffin nail shape. “It’s the new stiletto,” says Choi. As for the silhouette, because it looks like a coffin (hence the name) , it requires strongly tapered sides with a very straight edge across the top. A shorter version of coffin nails can also be known as ballerina nails.
Who it's best for: Pros say it’s not for everyone, as it needs major upkeep and length (natural nails are typically not an option here unless you’re super blessed in the length department).
8Stiletto Nails
@chaunlegendNamed after a pair of sky-high heels, “this shape is a statement—it’s both dramatic and high maintenance,” says Miss Pop. Because stiletto nails call for super-tapered sides, pointy centers, and hella length, you’ll need to commit to extensions.
Who it's best for: “There’s no such thing as a natural stiletto nail, since they’ll break too easily in this shape,” says Miss Pop. Choi recommends getting gel overlays versus acrylics to increase the length. “Acrylics can look thick, which is why I prefer using gel instead, since the shape will always look more elegant.”

9Square Stiletto Nails
@chaunlegendA touch skinnier than coffin nails, this square stiletto shape features long, tapered sides and a sharp square edge. The longer length makes them perfect for anyone looking to make a statement with their nails, and they're versatile enough that you can combine them with any combo of nail polish or nail art (tho, like, I'm super into the pink ombré situation pictured here).
Who it's best for: Down to try acrylics or gel extensions? Good, because they're a non-negotiable for this long nail shape.
10Flare Nails
@nailzbyriri_The coolest thing about flare nails (also known as duck nails), is that you can make them as extreme or lowkey as you want. All you need is a sharp, squared edge that flares out, and the rest is totally in your hands. Prepare to get festive with your nail art—the more abstract, the better.
Who it's best for: To get the sharpest, strongest edge possible, you’ll want to try out this nail shape with acrylics or gels (unless, like, your natural nails are made of steel).

11How to pick a nail shape
A quick PSA that there's no such thing as the best nail shape—it's all about finding a style that works great for you. Try to keep your lifestyle and preferred nail length in mind when trying a new look, since some shapes (see: anything in the coffin or stiletto family) will require a set of acrylics or gel extensions.
And when in doubt, there's no harm in chatting over your options with your nail tech—they'll be able to check out your natural nails IRL and give you a pretty good idea of which shapes are worth trying.
