Drapery Measuring Instruction

Simplify your curtain measuring process with our Measurement Finder, designed to guide you effortlessly through each step — ensuring a perfect fit, every time.

  • Step 1: Measure the Curtain Rod Width and Placement

    If you have installed a curtain rod, measure the length of the rod.

    If a curtain rod is not installed, first check where the curtain rod will be installed above and to the sides of the window frame. Consider how high you want the rod to be to create the desired visual effect.

  • Step 2: Know BTTO Standard Fullness

    To prevent your drapes from looking flat like a stretched sheet, it’s important to consider adding fullness for extra width. We use 200-250% fabric fullness to create the pleats, ensuring the curtains have a rich and luxurious appearance.

    • 2x Fullness for pinch pleat
    • 2.3x - 2.5x Fullness for triple pleat

    You don't need to add extra width for fullness, just choose the width you want.

Pleat heading style

For example, if your rod is 100 inches long, you would order two panels, each 50 inches wide, for the Pleat heading style.

The width of the drapery panel is measuredfrom the first pleat on the left to the last pleaton the right when the curtain is fully extended,not when it's stacked.

The length is measured from the top to the bottom of the curtain.

The fabric fullness: Double 200%, Triple 230%-250%
When stacked, the curtain width will be about 15~20% of the width you ordered.

Soft Top Heading Style
