Question: what size curtains do i need for a 72 inch window?
Answer: Example: If your window measures 36" wide (window width x 2 = 72"), you need curtains that will give a minimum width of 72" or 2 panels for that window. In this case 2 panels will give about 100" to 120" of width which will look nice and full. Always round up to the next full number.
