How to calculate curtain width and fullness
A curtain with fullness is a curtain that is pleated or gathered.
First of all: you don't have to worry about measuring curtain widths or curtain fullness yourself. We will always calculate the curtain width for you and use the correct amount of fabric, based on the heading style you choose. However, you might wonder why some heading styles are less expensive than others — and the answer lies in curtain fullness.
Curtain fullness is the relationship between the length of your curtain track or pole and the total curtain width, meaning the amount of fabric used across the curtains. Each heading type has its own fullness ratio, because some styles need more fabric to look their best when hung. For example, if your curtain pole is 1 m long and the combined curtain width is 2 m, the fullness is 2 times, written as 2x — in other words, there is twice as much fabric in the curtain widths as the length of the pole. The higher the fullness ratio, the fuller and more luxurious the curtains look, and the more fabric is needed.
120 cm (pole width) × 1.25 (fullness for Tab Top curtains) = 150 cm
The total width of your 2 curtains would be 150 cm when stretched out.
Curtain width per curtain: 150 cm ÷ 2 = 75 cm
