Paint the wall or ceiling in a single solid color just as you would a smaller wall. If you have one large wall in a room and three smaller walls, due to a slanted ceiling, paint the smaller walls a neutral uniform color and paint the larger wall a more vibrant color to make the wall pop.
Texturize the wall or ceiling if you want a solid-colored wall with a little more character. You can use a variety of items to texturize the paint on a wall. Dragging a comb, brush, piece of cardboard of rag over the paint on a wall as the paint dries creates its own distinctive texture to the paint, so experiment on a hidden corner of the wall until you get the look that you want.
Apply stencils to, or paint a mural onto, the large wall or ceiling. Use larger lettering stencils to write on the wall or ceiling’s paint job or use picture stencils to create a themed design, such as planets or safari animals or fruits and vegetables on a kitchen wall. Paint a jungle-theme or ocean-theme mural onto a large wall or ceiling to turn the space into a work of art if you have the skill, or hire someone to do the painting if you don’t.
Create a library or a place for mementos, photographs or collectibles by installing floor-to-ceiling bookshelves on a large wall. Since floor-to-ceiling bookshelves divide the space into levels, this technique can make an awkward large wall look smaller and more contained.
Choose multi-panel artworks that carry across a large wall. Place the panels side-by-side on the wall’s surface with spacing between them to help break up the space. Alternately, hang a number of framed posters, photographs or separate paintings over the wall’s surface to create the division.
