Measuring for curtains
How wide?

1. Measure the width of each window, including molding or trim if you want the curtains to cover them.

2. Determine the number of panels you need to order:

~ Multiply window width by 1.5 to 2 if you want curtains loosely gathered for a relaxed, tailored look. Divide your total by the width of a single curtain panel to get the number of panels you need.

~ Multiply window width by 2.5 to 3 if you want curtains tightly gathered for a full, luxurious look. Divide your total by the width of a single curtain panel to get the number of panels you need.
How long?

1. For a classic look, your curtain rod should be mounted 4" above the window opening, so measure from 4" above the window opening to approximately 1/2" above the floor to get curtain length.
 
2. If you want your curtains to create a grand "puddle" on the floor, add 6" to 8" to the length.
3. To create the impression of greater height in the room, position the rod 2" to 3" below the ceiling. Remember, this approach will likely expose the top edge of the window opening and some of the wall above it -- if you want them covered, position the rod at the standard height (see #1).
Rods & finials:
Rods are typically positioned 4" above the window. Rod length should be the same as the total fabric width. Add the length of two finials to rod length to get the total amount of space required.

About our curtain dimensions:

WIDTH: The width refers to a single curtain panel, even when they are sold in pairs.

LENGTH: The length of rod-pocket curtains is the distance from the top of the rod pocket to the bottom of the hem. It does not include ruffles or other decorative elements above the pocket.

The length of tie-top curtains is the distance from the top of the panel to the bottom of the hem. It does not include the ties.

The length of tab-top curtains is the distance from the top of the tab to the bottom of the hem.
