Fullness Ratio

Curtain fullness refers to the relationship between the width of your curtain rod or track and the amount of fabric used in your curtains. This is an essential aspect of curtain design as it determines how the fabric will drape and gather when hung. Different heading styles require varying fullness ratios, as some styles naturally demand more fabric to achieve their intended appearance.

Fullness is typically expressed as a multiplier (e.g., 2x). For example, if your curtain rod is 50 inches long and your curtains are 100 inches wide when fully extended, the fullness is 2x—indicating that twice the amount of fabric is used compared to the rod width.

While we always ensure the correct fabric amount is used based on the chosen heading style, you might notice variations in cost between different styles. This difference often stems from the amount of fabric required for the specific fullness ratio of each heading type.

1.2X FULLNESS
1.5X FULLNESS
2.0X FULLNESS
2.5X FULLNESS
3X FULLNESS

Example Calculation: If your curtain track measures 50 inches and you choose Grommet/Eyelet Top curtains, the recommended fullness is 1.5x. To calculate the total width:

  • Track width: 50 inches
  • Fullness ratio: 1.5
  • Total fabric width: 50 inches × 1.5 = 75 inches

For a pair of curtains, divide the total width by two:
75 inches ÷ 2 = 37.5 inches per curtain panel.

This ensures your curtains achieve the ideal drape and aesthetic when hung.

The table below outlines the fabric measurements we use for each heading style to ensure the proper width and fullness for your curtains.
