4 inch deep triangle louvered gable vents are actually 3 1/2 inches deep.  This is an industry standard started years ago.  The idea was if your stud is a 2x4, actual 1 1/2" x 3 1/2", then your gable vent should be 3 1/2 inches to match.  If you are mounting your triangle gable vent diretly to the studs, the vent should not extend past the studs into the attic.  If it does, it can be a safety hazard when you are walking near the gable wall.  Also, exending beyond the studs does not help in venting the attic.
