How to calculate the curtain fullness ratio

What does curtain fullness mean?

A curtain with fullness is a curtain that is pleated or tied.

First of all: you don't have to worry about curtain fullness. We will always use the correct amount of fabric, based on the Heading style you choose for your curtains. However, you might wonder why some different heading styles less expensive than others. And for that reason, you might want to read about curtain fullness.

Curtain fullness is the relationship between the length of the curtain track or pole and the amount of fabric used in the curtains. There are different fullness ratios for each heading type, because some curtains need more fabric when hung up. If your curtain pole is 1m long and the curtain is 2m wide, the fullness is 2 times, or written 2x. This means that there is twice as much fabric in the width as the pole length. 

Example: 

If your curtain track is 120 cm wide and you would like to order Tab Top curtains (2 separate curtains), multiply your curtain track or pole width as follows. 

120 cm (pole width) x 1.25 (fullness for Tab Top Curtains) = 150 cm 

The total width of your 2 curtains would be in total 150 cm when stretched out. 

Curtain width per one curtain: 150 cm / 2 = 75 cm 


The table below shows how much fabric we use for each style in order to achieve the right width for your curtains
