There are seven main nail shapes: round, oval, square, soft square, almond, ballerina (coffin) and stiletto. Round, oval and soft square suit short natural nails best, while almond, ballerina and stiletto look their best and last longer on extensions. Choose a shape based on your finger length, the width of the nail bed and how much you use your hands every day.
The main nail shapes and their names
| Shape | What it looks like | Who it suits |
|---|---|---|
| Round | The free edge follows the line of the fingertip | Very short nails, people who work a lot with their hands |
| Oval | Elongated, evenly rounded tip | Short fingers, as it makes them look longer |
| Square | Straight edge and sharp corners | Long, slim fingers, French manicures |
| Soft square | Straight edge with rounded corners | Almost everyone, a sturdy everyday shape |
| Almond | Tapers towards a rounded tip | Makes fingers look longer, also suits shorter nails |
| Ballerina (coffin) | Tapers, but the end is cut straight across | Medium-length and long extensions |
| Stiletto | Tapers to a point | Long extensions |
You will sometimes also hear of the lipstick shape (the edge cut at a diagonal), but it is more of a design choice than an everyday option.
How to choose a shape by finger length and nail bed
- Short fingers or a wide nail bed. Go for oval or almond. A tapering end makes the finger look longer. A wide square would make such a nail look even broader.
- Long, slim fingers. Almost any shape works, but square, soft square and ballerina look especially good: the straight edge balances the proportions.
- Narrow, long nail bed. A square or soft square shape visually widens the nail, while a stiletto would narrow it even more.
- Cuticle line. A simple rule: the free edge looks good when it echoes the shape of the cuticle line. A rounder cuticle line goes with oval or almond, a straighter one with square.
- Lifestyle. If you type a lot, work with children or use your hands for work, choose a shorter, rounder shape: it snags less and breaks less often.
Shapes for short nails
The shape of short nails is limited by the length of the free edge. The shorter it is, the less room there is to taper or cut corners.
- Short square nails look neat and modern, but sharp corners catch on fabric. Round the corners slightly and you get a soft square, which is far more practical.
- Short almond nails are possible if the free edge extends at least a little beyond the fingertip. Do not file the sides deep towards the nail bed, or the nail will be weakened.
- Oval and round are the safest choice for very short nails and for nails that are growing back after damage.
Which shapes are strongest and which break more often
Strength depends on how the load is distributed across the free edge. The wider and rounder the end, the fewer points where stress builds up.
- Strongest: round, oval and soft square. They have no sharp corners, and the load is spread along the whole edge.
- Medium strength: square (the corners split) and almond (if tapered too much).
- Most fragile without extensions: ballerina and stiletto. There is little material left in the tapering end, so these shapes are best done on extensions with a properly formed apex.
How to file the shape: file angle and grit
Grit is marked by numbers: the lower the number, the coarser the file. For natural nails use a finer file (180–240 grit), such as the STALEKS 180/240 file. Coarser files (100/180) are meant for shaping artificial nails. You can find all our files in the files category.
The most important rule for natural nails: file in one direction, from the side towards the centre, not back and forth. Sawing the file both ways makes the edge of the nail crumble and start to peel.
Filing an almond shape step by step:
- Set the length and file the edge straight so that all nails match.
- Mentally mark the centre of the nail.
- From each side, file diagonally towards the centre, leaving straight side walls up to the point where the nail separates from the finger.
- Round off the tip with a few light strokes.
- Check the symmetry by looking at the nail from above and from the palm side.
The most common filing mistakes that leave the shape uneven or cause the nail to break:
- Filing after soaking. A nail that has been soaked is softer and crumbles more easily, so it is best to shape it before the soak or cuticle softener.
- Filing the sides too deep. The side walls hold up the entire free edge. If you file them down towards the nail bed, the nail weakens and breaks right at the side.
- A file that is too coarse for a natural nail. A rough file leaves micro-cracks that are where peeling begins.
- Checking only from above. Asymmetry is often visible only from the palm side or from the front.
Shape a square by holding the file perpendicular to the end of the nail, and for a soft square just lightly brush off both corners afterwards. The shape of extensions is easier to adjust with an e-file; you can find out which bits suit this in our article on e-file bits.
Shapes for extensions: tips and forms
The shape of an extension is determined by the base the nail is built on. It is worth discussing the shape and length with your client before you start: they determine where the apex of the arch will sit, how much product you will need and which base to choose.
- Tips have their own starting shape. For example, curved extension tips are square-shaped, but you can shorten them and file them into an oval, almond or ballerina shape.
- Bottom forms give the most freedom: you can sculpt any shape on them, including a long stiletto. In the tools and forms category you will find both forms and tips.
- Top forms give all nails a uniform shape and arch straight away. You can learn how to work with them in the article "Nail extensions with top forms".
- Gel tips are a quick way to get length and shape without sculpting; read more in our article on Gel X.
Frequently asked questions
What are the nail shapes?
Seven are usually distinguished: round, oval, square, soft square, almond, ballerina (coffin) and stiletto. Less often you will hear of the lipstick shape, with a diagonally cut edge.
What nail shape suits short fingers?
Oval and almond, because a tapering end makes the finger look longer. It is best to avoid a wider square on short fingers.
Which nail shape is the strongest?
Soft square, oval and round. They have no sharp corners, so the load is spread evenly and the nail splits less often.
Which shape is best for extensions?
Any shape works for extensions, because the product and the arch reinforce them. Almond, ballerina and stiletto shapes last much better on extensions than on natural nails.
How do you file almond nails?
File the edge straight, then file diagonally from both sides towards the centre, keeping the side walls straight, and round off the tip. For natural nails use a 180–240 grit file and file in one direction.
