How do you Calculate Proper Attic Ventilation? The recognized building standard for balanced attic ventilation is the 1/150 rule. For every 150 square feet (sq. ft.) of attic space, 1 square foot of ventilation is recommended. Every square foot of ventilation is divided by 2 for the Intake (soffit ventilation) and the Exhaust (roof ventilation).
