Calculating soffit vents

How do I calculate the amount of soffit venting I need. My new roof has ridge vents (about 60 ft), and about 2 square feet of ventilation at each of two gables. The attic floor is insulated. The floor is about 60x20, and the peak is about 7 ft over the floor.

Thanks, Josh

Depending on the type of soffit you have one vent every 6 to 8 feet should be plenty. Good luck
