Measuring Curtains

In the catalogs when they say that the width (and other measures) and the price, and said pair they mean width of each panel or a total of two curtain panels? I called two companies and neither customer service representative know what to say ........., it is difficult to order! I need to know the width of two panels so that I can measure.

When he says this pair means the total width of the pair, the other sages of the list of panel width. So if it is appropriate width per pair, it is the width of two panels. And if it says the width per panel per panel, it is unique.
