What kind of nails do you use for sheathing?

Building codes since the late 1990s have required sheathing nails to be at least 8d box (.

Should sheathing be vertical or horizontal?

As Thor states in his book, if your designer requires staggering, then “stagger away”. In most cases by fully sheathing the wall, we already have a wall that is far stronger than it needs to be. So be careful about using the argument that because it is stronger that is the way it should be done.
Should sheathing overlap foundation?
In the same way that siding should overlap the foundation, so should sheathing.
