Choosing the right Length of Curtains can truly change the look of the room. Among the favorite options are those that reach to the floor. Such Curtains always look fine care about them is simple, and they help block dust.
To reach a classic and full style, choose Curtains that start from the ceiling to the floor.
Choose the Right Curtain Length
To give a fancy and rich feeling, Curtains should be as long as possible. Truly, too short Curtains simply do not work. The basic rule says that Curtains should not be much shorter than the floor height.
A little bunch of material on the floor with extra fabric creates a relaxed feel. Even so, if the Curtains lack enough material, such bunching can only leave the feeling that they never were well hemmed. Curtains of full Length should sit around one centimetre above teh floor, or at least one inch away.
For lower windows, one commonly chooses Curtains that end some inches under the window edge. If one adds around 15 to 20 centimetres under the window, one gets a nice fold and the Curtains look more attractive. When a window is tied too a door, the Curtain should match the Length of the door Curtain.
In United States, commonly used Curtain Length is 84 inches. Curtains for kitchen windows usually have around 78 inches.
In cases of doubt, better choose a bit longer than too short. This counts also if the Curtains end behind furniture. Ready-made Curtains come in sizes like 160, 205, 220 or 240 centimetres.
Most homes do not match perfectly to standard Curtain lengths, so one commonly must hem. Sometimes the cheapest way is to buy standard Curtains and fix them by hemming. One method is to extend the Curtain, fold it in half, add four inches to the planned Length andthen cut the extra material with good scissors.
Now let us talk about hanging the rod. Many folks place it three or four inches above the window frame, although some go up to ten inches up. If one hangs the rod higher, around six to eight inches under the ceiling, it most commonly looks better.
The rod itself should stretch at least six to eight inches past the frame on both sides.
The width also plays a role. The whole width of the Curtains should reach one and a half to two and a half times the window width. This way the material hangs fully with natural folds, not tight and thin.
Double Length of the rod is the usual standard. The right amount of fullness depends on the kind of top finishes that one uses. Curtains usually are listed by the width of one single panel, so two panels together give the whole width.
