Technically, it is 4' from lowest side of the excavation (hole). Measure 4' from bottom of your post hole digger and mark it with tape. It is deeper than you/I think, every time. The tape will save pulling out a tape measure numerous times to see how deep you are...trust me. Locally, I hit something immovable before 4' more often than not.
