That's a lot of horse ****.

I've installed a few ridge vents, and you usually cut maybe a 6 to 8"
wide gap in the decking at the very peak of a roof line (3 to 4 inches
on either side).

To theoretically balance out the size of that ridge opening with a
similar soffit opening, then a 6" fully-perforated soffit would work.

Also note that sometimes even a 2-foot-wide soffit isin't what it seems,
because the bottleneck will be the gap or opening between where the deck
passes over the wall header. Usually, the wider the soffit - the
lower-slope the roof is, making for a not-so-large header gap.

A ridge vent will give you a more even airflow pattern along the
underside of the decking compared to a few box vents.
