How to File a Nice Nail Shape: Choosing Square, Round or Almond to Suit Your Fingers

By Nanny Nails, nail salon in Nakhon Phanom | Updated 28 Sept 2026

You have a whole folder of saved photos of slim almond nails. Then you look down at your own hands: wide nail beds, and only a little nail past the fingertip. You are not sure it will come out like the photos, or whether another shape would suit you better. A nail shape is the frame around the colour. The right one makes the same polish look more expensive straight away. This article walks through the 6 main shapes, square, squoval, round, oval, almond and ballerina, how to file each one step by step, and how to read your own hands to choose, with real salon photos so you can see how each shape actually looks.

There is no single best shape for everyone. A good shape follows your own nails and fingers and fits comfortably into daily life. Some people wear almond and their hands look beautifully slim. Others look neater in squoval. The difference comes down to your natural nail shape, how much length you have, and what you do with your hands every day.

Before you file, get these 4 things ready

Whether the shape comes out well starts before the first stroke.

• A fine file A fine emery board or a glass file. If the board has a grit number, choose 180 or higher.
• Clip the length first Use scissors or clippers to take off the extra length, leaving a little to spare for shaping.
• Dry hands Clip after a shower if you like, but file once the nail is dry.
• File in one direction Always file in the same direction, because filing back and forth can weaken nails.

Why these matter, and which filing habits make nail tips split into layers, is covered separately in Filing your nails wrong until the tips split: 5 habits nail techs see. This article focuses on getting the shape.

One more thing nail techs always do is hold the file at the right angle. When shaping the tip, keep the file square to the edge of the nail, not tilted far toward the top of the nail or underneath it. Tilt it underneath and the edge ends up thin and sharp. Tilt it toward the top and the edge looks thick, with uneven corners.

Check 4 things on your own hands before you choose

Rest your hand on a table in good light and go through these one at a time. The answers tell you almost everything about which shape suits you.

1. The shape of your nail base

Look at the curve where the nail meets the cuticle. If the base is fairly straight and squarish, square or squoval will look natural. If the base curves like a U, round, oval or almond will blend in better. The simple rule nail techs use is to let the tip echo the base, so the whole nail reads as one shape.

2. Wide or narrow nail beds

If your nails are wider than they are long, shapes that taper, like oval or almond, make them look narrower and longer. Square makes the width stand out even more. Nails that are already long and narrow look lovely and balanced in square.

3. How far your nails extend past your fingertip

This is the room the file has to work with. If your nails barely extend past the fingertip, round or squoval is what you can do. With a medium free edge, oval or square work. Almond and ballerina need real length, because the taper has to come from the length beyond the finger, not from filing into the sides of the nail.

4. What you do with your hands every day

If you type all day, do housework, cook or look after small children, a rounded edge is easiest to live with. It does not catch on clothes or hair. Pointed or long shapes suit special occasions, or people who do not use their fingertips hard.

The chart above shows the 6 main shapes from left to right: square, squoval, round, oval, almond and ballerina. The length is the same for all of them. Only the tip changes. Below is how to file each one.

Square

The tip is straight across, both corners are right angles, and the sides run parallel. It looks sharp and modern, and it shows designs on the tip most clearly, because the tip is as wide as the nail. It suits long, narrow nails, slim fingers, and anyone who loves French tips or designs placed at the tip.

How to file a square shape

• Hold the file square to the tip and file the edge into one straight line, in one direction.
• Look down at the nail from above and check the line sits at a right angle to your finger, not tilted to one side.
• Straighten the sides so they are parallel, filing lightly along only the part of the side that extends past the finger.
• Touch each corner once with the file, lightly, to take the sharpness off while keeping the corner.

Worth knowing: the corners of a square nail take knocks and catch on fabric easily. If you use your hands a lot, squoval will be more comfortable.

Squoval

A square with the corners rounded off. The tip is still straight but there are no sharp corners. It works on almost any hand at almost any length, looks as tidy as square and lives as easily as round. If you are unsure what to choose, this is the safest answer.

How to file a squoval shape

• File the tip straight, as for square, first.
• Place the file at one corner, tilt it slightly, and draw a short curve from the side toward the tip 2 or 3 times.
• Do the other corner with the same number of strokes so both corners curve equally.
• The more you round the corners, the closer you get to round. Choose how soft you want it.

Round

The tip follows the curve of your fingertip. It is the most natural looking shape and the best one for short nails, because it needs very little length. There are no corners to catch, and the nail stays strong because knocks are spread along the whole edge. It suits people who use their hands hard, people just starting to grow their nails, and anyone who wants tidy hands with little upkeep.

How to file a round shape

• Look at the shape of your fingertip. A good round shape follows that curve.
• Start on one side and draw the file in a curve from the side edge up toward the centre of the tip, in one direction.
• Do the other side the same way, then blend the middle into one smooth curve with no flat spot or point.

Oval

Like round, but with a longer, egg-shaped curve at the tip. The sides run straight up first, then curve in toward each other at the end. Oval makes fingers look longer and slimmer without needing much length. It suits wide nail beds, shorter fingers, and anyone who wants a soft, polished look that works for the office.

How to file an oval shape

• You need a little nail extending past the fingertip.
• Leave the sides straight along the natural line of the nail until they clear the fingertip.
• From there, draw the file in a long curve toward the centre of the tip, one side at a time, in one direction.
• The tip should be rounded, not pointed. If it starts to come to a point, it is turning into almond.

Almond

The sides taper toward each other and meet in a small rounded tip, like an almond. Of the natural nail shapes, this is the one that makes hands look slimmest and longest, sweet and elegant at the same time. It goes well with glossy solid colours, nudes, cat eye and French tips. But it needs a fair amount of length, and a tapered tip handles knocks less well than a round one.

How to file an almond shape

• Let the nail grow a fair way past the fingertip first, at least as long as the length you want.
• Pick out the centre point of the tip in your mind. This is where the two sides will meet.
• Place the file at the side where the nail leaves the finger, angle it toward the centre point, and draw it in one direction. Repeat until that side tapers in a straight line.
• Do the other side at the same angle until both sides meet at the centre of the tip.
• Soften the tip slightly so it is not sharp.

The most important thing is never to start the taper on the part of the side still attached to the finger. The taper begins only where the nail clears the finger. File into the sides and the nail can easily break at the corner. Round fingernail corners only slightly to keep nails strong.

For a longer almond with a clearly slim tip like this one, most natural nails are not long or strong enough to hold that tip for weeks. Extensions give you this shape without waiting for your nails to grow.

Ballerina or coffin

The sides taper like almond, but the tip is cut straight across like square, so it looks like the toe of a ballet shoe. It looks bold and modern, and the tip leaves plenty of room for designs and colour fades. This shape needs a lot of length, which most natural nails cannot manage, so it is usually done on extensions.

How to file a ballerina shape

• Start with nails long enough, and taper both sides toward each other as for almond, but stop before they meet.
• File the tip straight across. The width of the tip is roughly a third to a half of the nail width.
• Touch the two corners of the tip to take the sharpness off.
• Look from above and check both sides taper evenly and the tip is not crooked.

At the salon, PVC extensions can be shaped in several ways, including ballerina, almond, square and stone. Send us the shape you want beforehand and we will prepare for it. How the different kinds of extensions compare is in PVC, acrylic and gel extensions compared, and how long PVC lasts is in How long do PVC nail extensions last?

Choosing a nail shape, in one table

Tips for getting all 10 nails the same

One pretty nail is not enough. What makes nails look fresh from the salon is every nail being the same shape and about the same length.

• Look from 3 angles From above the nail, from the palm side with your fingers curled in to see whether each nail extends past the finger by the same amount, and at eye level from the side to check the tip is not tilted.
• Count your strokes If the left side takes 4 strokes, the right side takes 4 too, so both sides curve the same.
• Go little by little Filing off is easy, putting back is impossible. File a little, then look, rather than filing in one go and ending up too short.
• Use the shortest nail as the guide If one nail has broken short, the whole hand looks even more easily if the others come down close to it.
• File your non-dominant hand first while your focus is fresh, then match your dominant hand to it.

Toenails do not need any of these shapes. Cut toenails straight across and use a file only to smooth sharp edges. Details are in Cutting your nails wrong until they grow in.

The right shape starts with your own hands

Look at the shape of your nail base, the width of your nail beds, how far your nails extend past your fingertips, and what you do with your hands every day. Those 4 things are enough to choose. If you are still unsure, start with squoval or oval. Both suit almost every hand. When your nails grow or a special occasion comes up, move on to almond or ballerina.
