Infield gloves range in size from basically 11” to 12”.For infielders of all ages, we suggest a glove that is between 11.5 and 11.75 inches long (12u-MLB). It might seem to be a small range, but 12″ is usually too big (especially for younger children), and anything under 11.5” gets very small and doesn’t leave much wiggle room if a ball is misjudged slightly.
