My local code list 3/8 or 1/2 inch OSB on 16" OC studs for exterior walls. I am ready to hang 7/16" OSB thinking it falls in-between the sizes listed somewhat. Before I put nail to OSB, would 7/16" work? I am in Virginia, my county goes by state code. Thanks for any advice.

Likely not gong to find exact "1/2", 7/16 is close enough and used all the time when 1/2 is called for.
No way would I use 3/8!.
