Why are ship portholes generally in round shape

You may not be familiar with the ship's porthole, which is simply the ship's window, another name of ship porthole can also be call side scuttle...Most of the windows that are used on ships are round shape, while other shapes are mostly invisible, So why are the portholes used on ships in round shape?

Firstly, the circle shape portholes can bear more pressure.

Geometrically, circle shapes can bear more pressure than other shapes. If it is square or a rectangle shapes, when under external pressure, the pressure will extend from the edge to four corners, and eventually the pressure will all converge to four corners. The pressure reaches a certain level, the glass will break. But round glass is not like this. When the round glass is squeezed by external pressure, the pressure will spread evenly on the round surface, and the pressure will not gather at a certain point. That way, the glass won't break because some point of pressure is too strong. Therefore, the ship which often travels in the sea is often hit by the strong wind and big waves at sea, and the round shape porthole is more suitable for this kind of environment.

Second, ship side scuttle with circular shapes have large area.

The circle area is larger than other shapes. This allows the ship to receive more light when sunlight enters into the ship cabin through glass. This is very good and advantage for a ship that has been at sea for a long time.

In addition, the round shape ship porthole window will be more beautiful in design, it is more beautiful from the overall shape of the ship.
