ᐅ Standard window width?

Hello everyone,

I have a question regarding the standard width of windows.
In our planned floor plan, the windows are listed with a width of 1 meter (3.3 feet) and a height of 1.25 meters (4.1 feet). This refers to the size of the opening in the wall, from one side of the masonry to the other.
Is a width of 1 meter (3.3 feet) standard, or is that too small?
I think 1.10 meters (3.6 feet) or 1.15 meters (3.8 feet) would be more comfortable.

What do you think?

Thanks and best regards,
Herb

I am familiar with the standardization of always +12.5cm (5 inches)...

There is no standard width for windows; whether they are 1.01 meters (3.3 feet) or 98 centimeters (39 inches) wide is relatively unimportant. However, you should keep in mind that modern (uPVC) window frames with tilt-and-turn hardware can already be 13 to 14 centimeters (5 to 5.5 inches) wide, so if your clear opening is 100 centimeters (39 inches), you will only have about 72 centimeters (28 inches) of glass left.

What you referred to as ypg is the rough opening size, but this probably matters less nowadays due to the wide variety of wall constructions. Solid masonry with bricks and mortar joints is no longer very common.

Thank you, Sebastian,
learned something new again.
The information about the frame width is also very interesting to me.
