HOW TO DETERMINE YOUR CURTAIN SIZE: Width means (Straight curtain from left to right): As a general rule, for proper fullness (pleated look, curves) panels should measure 2 times the width of your window/opening. For example; if your window measures 40" wide (window width x 2 = 80"), you need curtains that will give a minimum width of 80". It means 2 panels each has 40" or 1 panel that has 80". Length means (Straight curtain from up to down): Use a measuring tape to measure the distance from the top of your curtain rod (according to your hanging style) to the floor (or to the place where you wish to see the bottom of the curtain). If you use grommet hanging style; the distance between the top of the curtain & the top of the rod is 1,38 inches (3,5 cm). If you use universal or pinch pleat hanging style; the distance between the top of the curtain & the top of the rod is 1,1 inches (2,8 cm). While ordering curtains, please add
