Square
Square nails have straight sidewalls and a completely flat, straight top edge. The corners are sharp and defined. This is one of the most popular shapes for gel extensions and gel polish because it's strong, modern, and suits most nail lengths.
Works best on: Most hand shapes; particularly good on longer nail beds. Length: Short to long. How to shape square nails.
Round
Round nails follow the natural curve of the fingertip — straight sides with a curved tip that matches the shape of the finger. They're the most natural-looking shape and extremely low maintenance.
Works best on: Narrow nail beds, short nails, clients who prefer a natural look. Length: Short to medium.
Oval
Oval nails taper gently at the sides and finish with a rounded tip — more elongated than round, but softer than almond. They're universally flattering and one of the most elegant shapes for natural nails.
Works best on: Most hand shapes; particularly good on wide or short nail beds (tapering makes them appear narrower). Length: Medium to long.
Squoval
Squoval is a hybrid of square and oval — a square shape with slightly softened corners. It's arguably the most versatile shape: the strength and cleanness of square with the softness of oval. It's widely considered the most universally flattering nail shape.
Works best on: Almost every hand shape — the default recommendation for clients who don't know what they want. Length: Any length.
Almond
Almond nails taper at the sides and finish in a soft, rounded point — like the shape of an almond. They're elongating, elegant, and one of the most popular shapes for nail extensions. On natural nails, they require some length to work.
Works best on: Medium to long nail beds; elegant on most hand shapes. Length: Medium to long. How to shape almond nails.
Coffin / ballerina
Coffin nails (also called ballerina nails) taper at the sides like stiletto but finish with a flat, square tip instead of a point. Named for their resemblance to a coffin shape. Bold and trendy, they require length to read correctly — best achieved with extensions.
Works best on: Longer nail beds or extensions; statement looks. Length: Medium to very long. How to shape coffin nails.
Stiletto / pointed
Stiletto nails taper all the way to a sharp point. They're the most dramatic and fashion-forward shape — and the most impractical. On natural nails, they chip and break easily; most wearers use extensions. Not suitable as a long-term everyday shape for most clients.
Works best on: Extensions; special occasions; clients who prioritise aesthetics over practicality. Length: Long to very long.
How to choose the right shape
- For durability and practicality: Square, squoval, or round
- For elongating effect: Oval, almond, or squoval with some length
- For bold and trendy: Coffin or stiletto (extensions recommended)
- For the most universally flattering: Squoval — it works on almost every nail bed shape and size
- For clients with wide nail beds: Oval or almond (the taper narrows the appearance)
- For very short nails: Round or squoval — other shapes require length to be visible

Which nail shape is the strongest?
Round and oval shapes are the strongest because there are no corners to catch and break. Square shapes have corners that can chip on the edges. Coffin and stiletto are the most fragile due to their tapered tip — they're best suited to extensions rather than natural nails.
Which nail shape makes fingers look longer?
Oval and almond shapes are the most elongating. Their tapered sides and rounded or pointed tips create the visual illusion of length. Round and square shapes tend to look wider. Very long stiletto nails are also elongating but impractical for most clients.
