Different Ways to Install Vertical Blinds

Vertical Blinds Brisbane Installation

At Flower Blinds, all our fitters follow a meticulous measuring and installation protocol designed to maintain a high standard across all installs (regardless of who installs them).

Vertical blinds are the most versatile of all window coverings, providing wonderful visual aesthetics as well as functional privacy to any room, door or window.


In this article, we show you:

  • 3 basic ways Flower Blinds Brisbane installs vertical blinds

  • the pro’s and con’s of each fitting type

  • general rules for bracket placement

  • difference between an easy and hard installation

  • explain standard deductions

  • certain measuring considerations to maximize privacy and minimize gaps



Vertical Blind installed inside architrave

Vertical blinds fitted inside the window recess are called In-Reveal or Reveal fitted. These are usually flush inside the window architrave. The usual deductions taken are 5mm off the width, and 10mm clearance at the bottom.

Generally where possible, we would try to measure and install vertical blinds inside the windows for a clean and flush look with the frame.

In extremely unusual situations, where bottom sills are crooked or heavily warped, we would make the blade height to the shortest point of 10mm. What does this mean? If the height is 1000mm on the left side and 990mm on the right side, we would take our 10mm clearance from the 990mm, resulting in a finished blind height of 980mm. This is an extreme example, resulting in a larger light gap on one side, but it ensures the fabric blades do not touch the sill.


vertical blind installed with extension brackets

Where the window sills are too narrow, or there are some kind of mullions in the way, we would either consider opting for the 89mm slimmer size vertical blinds or installing the 127mm vertical blinds using extended brackets.

Vertical blinds fitted on extended brackets often stick out a little bit on each side, resulting in larger gaps at the sides. Sometimes this can be an issue, depending on the location of the window and any privacy concerns from the outside.

The size of the light gap is determined by how far out the bracket has to be fitted. In most cases the light gap is around 20-30mm and is not intrusive and quite acceptable. Alternatively for a completely flush look, consider opting for a “reveal fitted” 89mm narrow vertical blind instead.

Vertical blinds fitted on the face of an opening are called “Face Fitted” and are installed using L-shaped brackets. The fitting situation determines where the brackets will be placed, and how long the blinds will be measured.

A typical doorway with a timber architrave will have the blinds measured to be installed on the architrave with +100mm width added to the track, for extra privacy on each side of the opening. Brackets will be installed approximately 10-15mm inwards from the corner of the architrave (and never on the corner).

We have seen too many companies install vertical blinds on the corners of the architraves, only to have the weight pull down in those areas.

Face fitted vertical blinds on doorways will usually have a 20mm clearance off the floor, which is optimal. For windows with no recess depth (such as winder windows), we would fit a vertical blind on the face, and have the fabric drop just below the window sill.

Many Brisbane blinds companies sell different profiles of blinds. It might come as a surprise to you that there are also different levels of quality in the brackets themselves. As simple in function as they are, some hold more weight, some are held in with screws, some even are made from plastic. We are constantly amazed to see some major companies selling “premium” quality blinds, only to use cheap plastic fitting brackets which will become brittle in the long term. Our brackets (the better ones) are made from metal.

Although even the metal ones have many differences. Some metal face brackets have the clip riveted on, whilst others (the ones we make in our factory) are actually put together with tiny nuts and bolts.



Usually brand new apartments or older inner-city units will pose more technical challenges for a fitter to install vertical blinds. This is primarily a result of fixing into brick, steel, hollow or weak gyprock, reinforced concrete, or anything else unusually hard or unseen.
