We're currently redesigning bedrooms and looking to incorporate rooflights into vaulted ceilings. The most economical option is for large windows (1340x1140) which we are planning for, but almost everything I see on Pinterest has more smaller rooflights than fewer large ones. Is there any particular reason why that's the case? Bedrooms each have approximately 14m2 floorspace and 2.4m2 of windows (1200x2000). Thanks.

I would go with the larger ones.  Easier for fitting and operating blinds, external shutters, auto opening etc.

@eandg My guess would be that smaller windows you are more likely to fit in between 2 rafters and therefore less cutting needed. Only a guess though....or there is personal preference of course.

Smaller ones are better for differing amounts of airflow, larger ones better for uninterrupted views and more light.

That makes sense, thanks.
