How to choose the right shape gable or attic vent for a house...
The best questions would be how much vent-able space is available and how much air needs vented? Going off the calculations for net free air is not always perfect.
These computer calculations are just that, text book. If the home is a square or rectangle box, venting is easy. A vent on both gables of adequate size for venting with proper cornice vents for intake.
And do not fill the attic full of extra boxes. Once the loft is blocked by too many obstacles, the air flow is greatly restricted. The attic is not a storage unit.
Too many items in the attic can be a fire hazard. Items that need stored there can be placed safer towards the center of the attic still allowing air to escape from both gable ends.
