Hello everyone,
I am curious if there is a guiding principle for arranging windows. For example, in a rectangular room of 25 m² (270 ft²), having one window of 1.875 m (6.15 ft) or two windows each 0.9375 m (3.08 ft) wide. Does the room’s orientation affect the window arrangement? For instance, the room has exterior walls facing north and west.

I know this question might seem a bit basic. My main concern is to avoid making the rooms feel like dark, enclosed spaces.

There are no silly questions, only unhelpful answers :-)

As a rule of thumb: the window area should be about 1/8 of the floor area of the room to provide adequate natural light, regardless of the room’s orientation or function.
