TL;DR
A half-round gutter is a trough with a semicircular cross-section, the traditional profile on pre-1950s and high-end homes, hung from round brackets or threaded rods rather than screwed flat to the fascia. Its smooth curve sheds debris and self-cleans better than K-style, but it carries roughly 25 percent less water at the same width, so 6-inch runs are common.
