Umpires do not decide or announce changes in the strike zone, that is determined by the MLB Rules Committee. The last such change by the committee was in 1996, when the lower limit of the strike zone was changed from the top of the knees to the bottom of the knees. Umpires simply call the strike zone on what THEY PERCEIVE as the size of the zone in the rules in effect at the time.
The strike zone varies from batter to batter. The width of the strike zone is the width of home plate. The height is from the batter's chest (usually the letters) down to the batter's knees. The strike zone doesn't necessarily go by how tall the batter is, but by how the batter's stance is in the batter's box while waiting for the pitch.
the strike zone is wherever the umpire says
