Curtains, Blinds and Curtain Rods: Sizing Guide

Measuring for curtains: width, drop and rod position

Measure the window, then the rod. Curtain fabric looks full when the total panel width is about two times the rod length, so a 60-inch rod wants roughly 120 inches of fabric. Mount the rod 4 to 6 inches above the frame and extend it several inches past each side. For length, listings come in drops such as 63, 72, 84 and 120 inches: choose sill length, apron length or a floor-length panel that stops about half an inch above the floor. Check whether a listing is one panel or a pair.

Rod diameter, adjustable range and center support

Adjustable rods are sold by the span they cover, such as 28 to 48, 48 to 84 or 84 to 120 inches, so add the overhang on each side to your window width and pick the range with that total near the middle, not at an extreme where the rod is barely engaged or overstretched. Diameter is the strength clue: thin three-quarter-inch rods suit light sheers and valances, while heavier drapes want a thicker rod and sturdy brackets. Spans of about five feet or more need a center support bracket to avoid sagging.

Questions about Curtains, Blinds and Curtain Rods: Sizing Guide

What is the difference between sheer curtains and drapes?

Sheers are thin, light-filtering fabrics that soften sunlight and keep some privacy by day. Drapes are heavier and block more light and drafts. Many windows layer a sheer behind a drape on a double rod.

What size are standard shower curtains?

Most are 72 by 72 inches, with longer versions for tall ceilings and narrower ones for stall showers. A liner of the same size sits inside the curtain and keeps water in. Check both width and drop against your rod.

Can a tension rod hold heavy curtains?

Tension rods rely on friction against the window frame, so they suit light sheers and valances in small windows. Heavy drapes need a rod screwed into brackets fixed to the wall or frame. Check the weight limit.
