Fixing the size of a Window

Tall Windows: To visually lower the window place a piece of furniture under the window to bring the eye down. If you opt to place a piece of furniture under the window, use a fitted window treatment such as shutters, shades, or blinds to avoid entanglements with curtains and drapes.

Short Windows: To make windows appear larger or elongated, install a row of fixed shutters beneath or above the window and operable shutters on the actual window panes.
