On an “A frame” house with a 12 / 12 roof pitch would 6" gutters handle the rain from the roof or would 7" gutters be required? Also is there a requirement or somewhere where this is printed?
Thanks

I would try the manufacture site for that one.
Downspout rule is one sq inch per 100 sq feet however.

Barry you made that easy. :)I need to ween myself off the old paper books
Thanks Barry,
That’s what I needed.
From my point of view you also have to think about the run.
How long is the run. If it is more the 15 feet I would go with 7 Inches.
There is a lot to calculating gutters besides pitch and run.
Let says the shingle’s miss and over hang the shingle so there is a 1 inch exposure you lose 1 inch of gutters.
How is the fascia set , how does the decking finish off ?
So the question has to be looked at from many angles.
