The window size determines the feeling of space in your room.
SizeRoof windows can provide 2 to 3 times more daylight than facade windows. We recommend that the size of your roof window should be at least 20% of your room floor area.
Why does VELUX recommend 20% glazing to floor area?
For roof windows it can be generally said that 15% glazing to floor area usually puts you on the safe side of meeting the European Standard EN 17037 median daylight requirements.
Our rule of thumbs is therefore to have from 15% to 25% in order to reach good to very good daylight in your room. The simplified calculation of this ratio proposed on this website takes into account the full window size, including the frame, therefore our recommendation increase by 5%, to compensate for the frame area, ending up to 20%.
When should you consider more than 20%? If you know the window will be subject to shadow and obstruction, consider to stay on 25%-30% window to floor ratio.
If in doubt, ask for VELUX Advisory Service for a daylight analysis of your room.
