Spacing soffit vents?

How do I calculate spacing for soffit vents when used in conjunction with roof turbine vents? I plan to have 2 turbine vents for 2,100 sq ft of attic floor space. How many soffit vents will I need?

spacing

I've read on hear you need 1 sq ft for every 300 sq ft of attic and others have posted that you need 1 sq ft for every 150 sq ft of attic. Which is correct???

I used the 1/150 rule and guesstimated I would need 10 soffit vents, 5 on each side of the house about 10 ft apart along the eaves.
