Plausible Size Difference

Stories that feature giant guys that are bigger than normal people, but still within the range of what might seem possible—in other words, upwards of eight feet tall or so, but not as tall as a house or an office building. The term carries over from macro fiction, where the tag PSD separates giants that operate among normal-sized people and can do things like bend under doorways, from Giants that range beyond that, up toward skyscraper-tall and beyond. See also Size Growth, which involves getting bigger, either a little or to an extreme, and Very Tall, for guys that are pretty much normal but are taller than usual (in the general vicinity of, say, six and a half to eight feet).

Other tags that also fall under the category “Size/Size Difference”: Getting Taller, Giants, Shrinking, Size Growth.
