Are you a DIY hero- well then Do it yourself and Save $$$!  Below is some important measuring guide information and you can become a blind measuring super hero!  If you have any trouble along the way, never fear, contact us and we can help guide you. 

First things first… To measure like the professionals – ALWAYS use a metal measuring tape. A dressmaker’s tape or ruler will not give you an accurate enough measurement to ensure your blinds will fit correctly.

Make sure you measure in millimetres (mm).

You will next need to decide where your blinds will sit.  You can choose between mounting your blinds on the inside or the outside of the window reveal.

       Generally, inside mount is a popular choice as it provides a neater finish with the blind tucked away into the reveal.


Outside mounting, on the other hand, is useful as it blocks more light and can hide out of square windows.

An important point to note – do not assume that windows in the same room will be the exact same measurements. Its always safer to measure each window seperately. We cannot accept returns for blinds that are incorrectly measured.



Measuring For Inside Mount

  1. If you decide to inside mount your blinds, make sure you have enough room for them to fit properly. Look out for handles, tiles and other obstructions as these may hinder the operation of your blinds.  Make sure you have enough architrave depth to comfortably house the blinds inside.
  2. When inside mounting your blinds, remember there will always be a small gap at the sides to allow for the blind to be operated without catching.Most window types have an aluminium edge on the glass so privacy may not be an issue, however some windows are designed so that the glass is flush with the reveal. In this case you may wish to outside mount your blinds if privacy or light gaps are an issue.
  1. Start by measuring the width of the opening from inside architrave to inside architrave and writing it down. For the best results, measure the width at the top, middle and bottom of the opening and write down the smallest measurement.  This will help ensure the blind will fit into openings that are slightly out of square.  This is more common than you might think!Measure in millimetres to the nearest millimetre.
  1. Now repeat the process for the drop, measuring the height at the left, middle and right of the opening. Write down the smallest measurement to the nearest millimetre.

Write your measurements down and find the blinds you are looking for online. Whether you choose ReadyMade or custom crafted blinds, make sure you don’t take off any deductions as we will take off just the right amount so your blinds fit perfectly!

Measuring For Outside Mount

Most outside mount blinds are measured from the outside of the architrave on one side to the outside of the architrave on the other.  Some windows, however, do not have an architrave fitted, in this case or if you just want extra coverage, you may choose to fit your blinds to the wall above or on either side of the window.  The choice is yours.

  1. Should you choose to outside mount your blinds, you then need to decide just how far past the window opening you want your blinds to finish. ReadyBlinds will take no deductions from the measurements you provide for outside mount blinds.
  2. Once you have decided where you’d like your blinds to sit, you can start measuring. Firstly measure the width, taking into account how far past the window opening you would like your blinds to finish.As the headrail will be mounted to the top, you really only need to measure this width when outside mounting.  Keep an eye out for any obstructions such as handles or mullions.  Write down your measurement in millimetres to the nearest millimetre.
  3. Now measure the height, ensuring you measure from the top to the bottom of exactly where you want your blind to sit. Measure in three places (left, middle and right), checking for obstructions as you go.
  1. Remember, ReadyBlinds will not take off any deductions for outside mount blinds so you need to provide measurements for the exact space you’d like your blinds to cover.
