How to Make a Small Window Wall Look Longer

Paint your walls neutral or cool colors, like white, beige, violet, light green or light blue, to make the entire room appear more expansive. Paint your ceiling the same color as your walls, or a slight shade lighter, to extend the wall and create the illusion of gradual height.

Paint vertical stripes on your small window wall to suggest height. If the room is narrow, paint the stripes darker than the base color to create the illusion of depth. If the room is too wide, paint the stripes lighter than the base coat, so the wall appears closer.

Install full-length vertical blinds to make it seem as if the window reaches all the way to the floor. Choose vertical blinds with wide planks to implicate width, as well as height. Avoid shades or horizontal blinds. Shades will visually break up the expanse of the window and create a choppy, stunted appearance; horizontal blinds will cause the eye to look from side to side, rather than upward.

Mount full-length curtains wider and higher than the actual parameters of your window frame. Place your curtain rod as close to the ceiling as possible, and extend the rod past your window on both sides. If there is a large gap between your curtain rod and the top of the window, install a bamboo shade to camouflage the empty space. Pick curtains the same color as the walls for a seamless transition.

Allow your window wall to be a backdrop for short furniture, so the wall looks taller in comparison. Emphasize the flow of space with furniture that has open space underneath, rather than wide, low pieces that act as a visual block.

Place vertical groupings of wall art parallel to your windows. Position pieces at eye level going upward toward the top half of the wall, to further the illusion of height.

Place short plants, or a low vase with short flowers, in your window so the wall looks long in comparison. This will also create the effect that your window frames nature, regardless of your outside view.
