What Are Standard Drapery Lengths?
Choose drapery in a standard length to avoid costly custom curtain orders or spending extra time hemming your drapes yourself. Keep your drapery length proportional to the rest of your room. Plan to hang your drapes 4 to 8 inches above your window and measure accordingly to choose the correct length.
Choose puddle-length draperies for a formal or historical look for your room. Standard puddle draperies extend anywhere from 4 to 8 inches beyond the floor for a "puddle" of fabric on the floor. Choose puddle-length draperies for curtains that remain fixed and are not in high-traffic areas.
Trouser-length draperies blend the drama of puddle-length draperies with the more practical floor length by extending curtain fabric just 1 to 2 inches past the floor.
Standard floor-length draperies, also called full-length draperies, should just touch the floor or hang only 1/4 to 1/2 inch above the floor. Floor-length draperies are a popular choice for many decor styles.
Sill-length draperies at the standard length end right at the window sill for a less formal look or to accommodate items below the window, such as radiators or furniture. Sill-length draperies are also a common choice for children's rooms for safety reasons.
