The Shape of a Shirt Cuff: Round, Cutaway, or Square?
Written by Kenji Tanaka
Look at the cuff of a shirt and you will notice that there are several different shapes.
Some have rounded corners. Others have their corners cut away at an angle. Some remain completely square.
When ordering custom dress shirts in Bogotá, these shapes are often treated simply as design choices.
But there is a more interesting question behind them:
Why are shirt cuffs shaped this way in the first place?
Is it simply a matter of appearance?
A Cuff Sits on a Moving Part of the Body
A cuff sits around the wrist.
That may seem obvious, but the wrist is one of the most active parts of the body when wearing a shirt.
We bend our arms.
We rotate our hands.
We place our hands on a desk.
We reach into a pocket.
We check our watch.
Every movement affects the cuff.
And the cuff does not exist on its own. A jacket sleeve may sit over it, while a watch may sit around the wrist.
In other words, a cuff cannot be designed only for how it looks when the shirt is lying flat.
What happens to its shape when the shirt is actually worn and the body moves matters as well.
The Corner of a Square Cuff
A square cuff has a very clear and precise appearance.
Its straight lines and right angles give the shirt a clean, structured look.
But when worn, that sharp corner can sometimes become a slightly awkward point.
As the wrist bends or the cuff is pressed against something, the corner can be pushed out of shape. The crisp right angle that looks so clean when the shirt is laid flat may become distorted when wrapped around a moving wrist.
This does not mean that a square cuff is inferior.
Quite the opposite.
It is precisely because the right angle is retained that this characteristic can occur.
And this is what makes such a small part of a shirt interesting.
A shirt is designed on a relatively flat surface, but it is ultimately worn on a three-dimensional, moving body.
The Idea of Removing the Corner
This is where rounded and cutaway cuffs become interesting.
A rounded cuff has no sharp corner. The result is softer and more continuous.
A cutaway cuff removes the corner with a diagonal line. The result is more geometric and sharper.
As a result, there is less of a distinct corner to be pushed or distorted when the wrist moves.
The point is not necessarily that these shapes make the cuff “easier to move.”
It is more subtle than that.
The question is:
How does the cuff maintain its shape while the wearer moves?
That is an important distinction.
Clothing is not static. It changes shape with the body.
A small curve or diagonal line can therefore have an effect that goes beyond decoration.
Then Put a Jacket Over It
The difference becomes even more noticeable when the shirt is worn under a jacket.
Only a small portion of the cuff may be visible beyond the jacket sleeve.
Yet that small visible area contributes to the appearance of the entire hand and wrist.
A rounded cuff introduces a curved line.
A cutaway cuff introduces a diagonal line.
A square cuff shows a straight edge and a defined corner.
The cuff is also seen alongside the jacket sleeve and, often, a watch.
So the shape of a cuff is not only a shirt detail.
It is part of the overall composition of the hand and wrist when the shirt is worn with a jacket.
Shape and Construction Are Two Different Things
There is another point worth clarifying because cuff terminology can easily become confusing.
The shape of the cuff and the construction of the cuff are two different things.
Rounded, cutaway and square describe primarily the shape of the outer edge.
Single and double describe the construction.
A single cuff uses a single layer of cuff fabric.
A double cuff is made longer and folded back to create a double layer, and is generally fastened with cufflinks.
And then there is the term French Cuff.
This is where the terminology can become confusing.
French Cuff is generally another name for a Double Cuff.
In other words, Double Cuff and French Cuff usually refer to the same basic construction.
The important distinction is that these are not the same classification as rounded, cutaway or square.
You can therefore have combinations such as:
- Double / French + Rounded
- Double / French + Square
- Double / French + Cutaway
The construction and the outer shape are two separate decisions.
Once you see them this way, cuff terminology becomes much easier to understand.
Why Does the Cuff Have This Shape?
Looking closely at a cuff reveals something fundamental about clothing.
There is the shape of the garment when it is laid flat.
There is the shape when it is placed on the body.
There is the shape when the arm moves.
And there is the shape when the shirt is worn underneath a jacket.
These are not necessarily the same.
That is why the shape of a cuff should not be considered merely decorative.
Clothing is designed on a flat surface, but it is completed on a moving body.
Of course, there is no universally correct cuff shape.
A rounded cuff is not inherently better than a square cuff, and a cutaway cuff is not necessarily more practical.
Each has its own character.
What matters is understanding why the shape is there and what it does to the appearance of the shirt when it is actually worn.
At Uniontailors, bespoke shirts in Bogotá are approached from this same perspective: not only how a garment looks when it is laid flat, but how it works and appears on a moving body.
A cuff is a small detail.
But it is also one of the places where construction, movement and appearance meet.
And once you start looking at cuffs this way, something that previously seemed like a minor detail can become one of the more interesting parts of a shirt.
