But they’re not only a visual choice. On a window, vertical blinds have several other benefits. First, many styles are very easy to adjust. While other window coverings have to battle gravity, these simply move side to side, often on a fixed track at the top of a window. A second benefit is their fixed length. While other styles take time to move up and down, vertical blinds always extend to the same length, making them a uniform presence and a pleasing sight at all times.
