How to accurately measure the size of curtains to customize the perfect curtains for your Windows?
Read this most detailed instruction on measuring curtains carefully. We will introduce it to you in detail.
If you haven't installed the curtain rod, please install it first according to the following suggestions.
Determine the installation height of the curtain rod. We suggest it be 5 to 10 inches higher than the upper edge of the window frame. This can give your window the illusion of being taller and make it more beautiful.
To determine the width for installing the curtain rod, we suggest reserving additional width (5 to 15 inches) on both sides of the window frame respectively. So that the curtains can be stacked.
When you have completed the installation of the curtain rod or you already have one. You can measure the height and width now to make the curtains fit your Windows better.
Regarding fullness
To prevent the curtains from looking like elongated bed sheets, you need to consider adding fullness to certain title styles to increase the coverage width.
We have already taken into account the fullness of the fabric when designing. For example, Pleated Style creates pleats with a fabric fullness of 200 to 330%. Make sure that the appearance remains full and plump even after the curtains are closed.
If you need a fuller effect, you can increase the fullness by an additional 1.3 to 2.0 times. For example: If your regular width is 50 inches, you can customize curtains that are 65 to 100 inches wide. This is a personal choice and not a mandatory requirement.
Below is a real photo of a high-fullness curtain (about 2x). Please experience the rich visual effect brought by the high fullness for yourself.
1、How to accurately measure pleated and flat hook curtains？
Width: It refers to the width from the end of the left pleat to the end of the right pleat when the curtain is fully unfolded, rather than the width when stacked.
If the curtain rod is 100 inches. You can order a 100-inch curtain or two panels, each 50 inches wide in pleated style.
Length (height):measured starting from the eye ring of the curtain hook.
2、How to accurately measure soft top & grommet curtains？
Width: The width of the single panel when fully expanded = the width of your order. You should measure the distance between the two ends of the curtain rod.
For instance, if the width of the curtain rod is 100 inches, you can order one 100-inch curtain or two 50-inch curtains
Length (height)：measured from the top of the pole to the floor or the end point you prefer.

3、How to determine the most attractive length (height) of curtains?
Different curtain length (height) will bring different visual experiences to your room.
Sill height：The hem of the curtain is near the windowsill, with a small coverage area that cannot cover the wall, but it will save some expenses.
