Getting Taller

Stories that feature guys that become noticeably taller than average, but still more or less within the normal range of human height. Often this is used for guys that remain the same “width” and end up a bit stretched-looking. By contrast, Size Growth covers getting bigger in size and height (either a little or to an extreme). Plausible Size Difference is a giant who can operate among normal-sized folks.
