Short curtains are typically only used when long curtains are unrealistic (such as when a radiator, the bed headboard, or some other object would interfere with the curtains). In addition, long curtains provide a better aesthetic and can make the room appear bigger, especially when hung higher than the window frame.
Short Curtains
Visually speaking, high-water style is not the most appealing way to hang curtains. The shorter length can appear dated. Also, it can cut the visual height of your room in half. From a purely practical standpoint, however, short curtains are sometimes the best option.
If you are interested in stationary panels, you will want your curtains to be long enough to lightly brush the floor, but not so long that they bunch up in a pile. A good rule of thumb is for your curtains to break anywhere from a ¼” to ½” from the floor, similar to a break in pant legs on your shoe.
Making Your Room Look Larger or Smaller with Curtains
High-hanging curtains with long vertical stripes create the illusion of height, which is excellent for low ceilings. However, short curtains and horizontal stripes shorten your wall height and make the room appear smaller.
Floor-length curtains will elongate your window and make your room feel taller. Since they don't quite touch the floor, curtains hang perfectly straight. The hem also stays clean and doesn't pick up dirt, dust, and pet hair. Where to use them: Living rooms, family rooms, or any high-traffic area.
Hanging long drapes on a short window is one of the easiest ways to increase the importance of the window and bring it into proportion to the room. Short drapes on a short window call attention to the size of the window and reduce the significance of the room, window and drapery style.
A common rule for displaying curtains properly says the curtains finished width should be at least 2 times the width of your window (if not more - sheers can be 3 times the window width) to achieve a look of proper fullness.
Curtains absolutely can make a room look smaller or larger, depending on their design. Thick curtains and dark curtains are known for making a regular room look slightly smaller, while sheer curtains made of lightly-colored fabrics are ideal for helping to visually expand a room's size.
A rule of thumb (from Architectural Digest) is that curtains should be hung between four to six inches above the window frame, so install your curtain rod accordingly. When you hang the curtain rod high, it will make the window appear taller.
Floor length: Long curtains that go from above your window frame all the way to the floor to create a traditional, formal look. Typical curtain length for this style is 84 to 96 inches; these curtains will fall about 1/4-inch above the floor. They are ideal for living rooms, bedrooms and dining rooms.
Generally, you should avoid anything shorter than 96 inches, unless you have very low ceilings. When in doubt, go with longer curtains rather than a shorter, cut off length. If you can't find ready-made curtains that fit your home, you might need custom curtains.
The answer to this question is important because it can affect the way we do our decorations. Yes, curtains should be long enough to touch the floor. With a few exceptions, the longer the curtains are the more stylish and elegant it will look. This is why most standard ready-made curtains are lengthy.
No matter what the ceiling height, the minimum distance from the top of the window casing to the curtain rod is two inches. To create the illusion of height, mount the drapery rods close to the ceiling. This is particularly important to do if the room has low ceilings. Use these same rules when the windows are arched.
Your best move is to hang curtains within 8 inches of the top of the window frame. For very tall windows, which are popular in many modern homes, that means placing the rod as close to the ceiling as possible—in fact, you might want to install rods designed to actually hang from the ceiling.
Big floral patterns make a room appear larger. Install wallpaper with horizontal stripes to make a room seem wider, or commit to vertical stripes to stretch the room visually and raise the ceiling. A busy pattern featuring chevrons, simple geometric designs, or a texture that mimics marble can make a room seem bigger.
Where do curtains come in? By restricting the flow of air between the warm and cold areas of a space, curtains aid in heat retention. Also, double-glazed windows will allow heat to escape, but heavy curtains will act as a barrier, preventing air from flowing from the main room to the window.
Use contrasts and light colors that make rooms look bigger
Light and bright walls are more reflective, making a space feel open and airy, which helps maximize natural light's effect. Dark shades tend to absorb light, making rooms feel smaller. Accent walls to make a room look bigger is another way to go.
The material should barely touch the floor or hover half an inch above. Use this approach for café curtains, too, short panels covering only the lower portion of a window, hitting the sill, which works well in kitchens and bathrooms, where long drapes or curtains aren't practical.
In Closing. For a 9-foot ceiling, 96-inch curtain panels are typically a good fit. This allows you to hang curtains that reach the floor, with the rod placed one foot from the ceiling. If you prefer curtains that pool on the floor or curtains that hang higher, just pick the next size up.
When you buy them in stores or online, there are two standard lengths: 84 inches and 95 or 96 inches. The length of the curtain dictates the height of the rod. If you buy 84-inch-long curtains, the rod must be mounted roughly 84 inches from the floor if the curtains hang from the rod without rings.
Hovering an inch or less above the floor
This option is also more forgiving than those that precisely hit the floor, which means your measuring and hemming won't be derailed if it's a few millimeters off. It also means you don't have to worry if you have slightly uneven floors.
Drapes may stretch. Fabric is made of threads woven together, and there is no glue holding these threads in place. Knowing how the fabric may react after hanging will help you choose fabrics that should not stretch.
