I recently bought pleated blinds and just now realized that they are not wide enough. The instruction says they have to be at least 2 centimeters wider than the window (on each side) they are covering. They are missing 3 centimeters on each side.

What is the reason for that requirement?

The mounting system can be seen here:

Mounting system part 2:


It's probably not a requirement. It's probably so that less light is shooting past the blind through the gap between it and the window frame.

If it is a requirement it probably has to do with the mounting system, which we have no information about.

  • Thanks for you reply. I edited my question to add pictures of the mounting process. If needed I can add pictures of the parts as well. – Tom K. Feb 17 '18 at 14:29
  • Then my first paragraph holds true. For outside (face) mounting you definitely want them slightly larger than the window opening. It's not a requirement, but in my experience you'll have way too much light coming past the blinds otherwise. It's your call of course. – isherwood Feb 17 '18 at 14:38
  • Alright. It will be mounted inside and its main purpose is to work as a privacy shield. So two small gaps on the outside probably won't matter. Thanks again. – Tom K. Feb 17 '18 at 15:05
