A 4x4 post is usually 3.5” x 3.5” which is just under 5” corner to corner.
if you haven’t purchased the auger, 8” is probably the most useful. A 6”auger will work fine.
A deeper hole will give more rigidity and can be backfilled with fine gravel or sand.
if you are in the market, after reading a review in Farm Show, I purchased a Ryobi 40 volt machine which came with one battery , a charger, and an 8” auger. I also bought a set of extensions. it is powerful and can do many holes on a single charge. it is reversible and much safer to use than a gas unit.
