In the local "learning to pitch" 7-9 year old league, the strike zone is ankles to shoulders and 6 inches on either side of the plate. The width of this zone means that a baseball called for an inside strike could be almost three feet from a ball called for an outside strike. And since men are going to tend to overestimate 6 inches
the actual called strike zone is likely to be even wider than that.
Since most pitches at this age have an exaggerated arc, having the ankles be the bottom of the zone means that pitches that land near the front edge of the plate are often technically strikes.
