How to Install Vertital Blinds Properly

For decades the vertical blind was almost exclusively used in office buildings, but as our tastes in home décor steadily became more diverse, various styles of vertical blinds were released to the market.

Whether you are remodeling a new home or just sprucing up a particular room, your choice of window coverings ranges from simple curtains to futuristic, programmable glass, and everything in between.

A lot of us shy away from choosing vertical blinds due to being worried that the installation process will be overly complicated and time-consuming. Installing vertical blinds properly is not as difficult as you may think, and with this guide, we aim to make the process even simpler.

Tools you need

  • Pencil;
  • Tape measure;
  • Electric drill + bits;
  • Screwdriver;
  • Screws;
  • Blinds;
  • A helper;
  • Ladders / stepladders.


  • Inside mount – Blinds which are mounted inside the window frame.
  • Outside mount – Blinds which are mounted outside the window frame.
  • Valance – An L-shaped component which covers the headrail.

Pre-installation preparation

Regardless of which type of vertical blinds you would like, inside or outside mount, the first thing you should do is measure the window so that you know the size of blinds you need to buy.

To ensure that the blinds fit correctly, you must first measure from below the window at the point where you would like the blinds to hang. From that point, measure the height to the place where the headrail will be installed.
