Before jumping into how scale and proportion affect drapery design, let’s start with some basic definitions. Scale is the comparative size of one object to another. Proportion refers to a general relationship in size between two objects.
We know that you as designers use the concepts of scale and proportion all the time in your work. Standard countertop heights are scaled to fit the height of the average person.
And you may recommend that the coffee table be two-thirds as long as the sofa or an area rug extends 18” beyond the dining table on all sides.

Hems and Headers:
When we are considering scale for drapery panels, we are comparing the size of the hems and headers to the finished length of the drapery panel itself. The most common scenario is 4” hems and headers for a panel that is 90” finished length.
Using the concept of scale (the comparative size of one object to another), 9 ft. panels should have 5” hems and headers, 12 ft. panels should have 6” hems and headers and two-story panels like these need 8” hems and headers.
On the flip side, cafe curtains need smaller hems and headers (usually 3”) to maintain proper scale. These short curtains installed on a bunk bed for privacy are another example of proper scale.
Widths of Material:
When considering proportion for stationary drapery panels, we are determining how wide the drapery panel should be — that is the number of widths of material we need to seam together for each panel.
Just as the size of the coffee table relates to the size of the sofa, we want our drapery panels to relate to the size of the window. We do not want our drapery panels to overpower the window or look like a strand of spaghetti hanging next to the window!
A good rule of thumb is 1 WOM (width of material) for up to a 48” wide window, 1-1/2 WOM for windows 47” to 96” wide and 2 WOM for windows over 8 feet. Of course, if the drapery panels are operable, the required widths of material is calculated so that the panels fully cover the window when closed.
