In recent years, the trend of DIY home decoration has become increasingly popular: from small things like veneer painting to large things like building houses and walls. Curtains, which are said to be the finishing touch to a space, are also being replaced by more and more people who are moving away from the idea of ​​only being able to order curtains from curtain shops and have them installed by others, and instead are doing it themselves to create their own unique living atmosphere.

When buying curtains, whether you decide to choose from a large department store or an online store, the first question you usually face is:"What size curtains do I need?" "How do I measure my window to avoid buying the wrong size?"

Accurately measuring the size of windows or other planned installation locations is essential to avoid situations such as tracks being too wide to fit in the frame, window frames being too shallow to install, or fabric being too small to cover the window glass.

Incorrectly sized curtains will not only significantly reduce their ability to block out light, but also greatly affect the overall style and visual appeal! Follow these 3 steps to measure your curtains, and buying the right size will be a breeze!

Now that we have determined the maximum flat area where we can install the curtains, the next step is to decide how large the area to be covered is within that maximum flat area; the size of the covered area is the curtain size!

Please note that the "inside/outside the frame" mentioned here does not refer to the metal frame of the aluminum doors and windows, but rather to the "...""Cement window opening"So never measure the size of your window glass!

The image below illustrates the difference in effect between installing curtains inside or outside the frame:

   Measure the left, center, and right positions respectively. Record the largest of these three measurements as the curtain height.
   
3. Measure the depth of the window frame and the thickness of the protruding window frame handle:

STEP 1～3

1. Curtain width calculation :

⚠️ Things to note when deciding on curtain size ⚠️

■ The width and height of the curtains must not exceed the installable surface area obtained in "Step 1".
■ It is important to note that the area covered by the curtains must be completely flat and free of any bumps or unevenness.
■ If installing within a frame/curtain box, it is recommended to reduce the width by 0.5-1cm to allow for flexibility. This avoids situations where slight imperfections in the wall finish prevent the curtains from being installed.
■ The curtain dimensions indicated on the shipped product are the total width and height including all system parts.
■ If space permits, it is recommended to reserve a depth of 15 cm or more. This allows greater flexibility for future curtain replacements and reduces potential restrictions.
