measure for: draperies


All drapery styles come with the appropriate fullness built in. So all you need to do is tell us the area that you want your drapery to cover, and we will add the additional measurements to create the right look. (The measurement that you specify for your drapery will be the same as the rod width.)

  1. Begin by measuring the window width from opening to opening or molding to molding.
  2. Add a minimum of 8" (4" on each side) to allow the treatment to extend beyond the window frame.
  3. If you want the open panels to clear the glass, use the stackback chart below (This is highly recommended for larger windows).

Stackback is the amount of wall space needed if open panels are to clear the glass completely. This dimension, added to the window opening, gives you the proper rod width.

Begin by measuring the window opening, then consult the stackback chart below. Find your opening measurement and read across the right rod length.

  2. Double layer treatments (over a drapery or outside mounted blinds underneath) - first calculate your drapery width, then add an additional 1" per side for clearance.


All styles are recommended to be installed a minimum of 4" above the window opening or molding.

  1. Height is measured from top of valance or cornice to the bottom.
