About this breed's data: The AKC recognizes two varieties by height: the 13-inch (up to 13 in, roughly under 20 lb) and the 15-inch (over 13 up to 15 in, roughly 20-30 lb). Any hound over 15 in is disqualified. This page covers both in one range. 'Pocket Beagle' is a marketing label, not an AKC size.
