How do I measure my window for a blind?

Measuring is easy.  Follow our simple steps in the below video:


1) You will need:

  • Metal measuring tape – this ensures you get the most accurate results
  • Pen and paper – it is best to write down your measurements as you go
  • Ideally a friend – particularly if it is a large window

 2) Measure your finished blind width

  • For exterior fit blinds:
    Simply measure the width you want the blind to cover – this should include the window frame. It is standard to make blinds 50mm wider for a good cover. Blinds look better bigger than 1mm too small and as fabric can contract when ironed or sewn, it is much safer to plan them slightly larger.  This will not be noticeably when the blind is up or down. It is also useful for them to a be a bit wider in a bedroom – to block out any light.
  • For interior fit blinds:
    This is a blind that sits inside the window cavity – measure the narrowest width of the recess, then deduct 5mm to ensure the blind will be able to be pulled up and down. Let us clearly know that you have deducted 5mm. To get the shortest width we recommend you measure various positions across but at least top, middle and bottom of the internal frame.


 3) Measure your finished height

  • For exterior fit blinds:
    Simply measure the length from where you want to install the blind to your desired length. Ideally you mount the blind 100mm above the window so that the blind doesn't block the window when it is pulled all the way up. As well we recommend you have the blinds finish 100mm past the sill to give it a good cover and look. While these are standard recommendations you may want to adjust them if your blind should match the top of an existing curtain or blind, you have a specific look or design preference or there are space restrictions to take into consideration. 
  • For interior fit blinds:
    Measure the shortest length from the top of where you will recess it to the sill. To get the shortest length we recommend you measure various positions but at least left side, middle and right side of the internal frame.

It is best to measure both sides of your window as in some houses this can be slightly different. 

Don't forget:
Measure the window width and height in three locations to determine the widest/narrowest part of the window. Decide where to put the pullside – this is the cord/chain that you use to raise/lower the blind. There is often one side that is more practical than the other – otherwise just choose whichever side feels good to you.


How much fabric do I need for blinds?


You need to ask your roman blind maker to do this for you as all makers have slightly different requirements.  You need to give them the width of the fabric you like, and the horizontal and vertical pattern repeats.


How do I know whether to do curtains or blinds?

This is just a matter of personal preference unless there is something in the room prohibiting one from being an option.  We are happy to advise on what might be the best option for your window – just email through a photo of your space to or pop into our store.

Blinds are an excellent solution for windows that have limited space either side or if you are after a clean, minimal look. They are also ideal for windows that sit quite high off the ground such as long windows above a bed or furniture.

Should I do an external or internal fit blind?

External fit means the blind covers your window frame and an internal fit sits inside the frame - you need to decide this before you measure. Have a look at your window and imagine the blind in place - some windows don't have room for the blind to sit outside. You can email us a photo of your window and we can advise you.

Outside of the frame has the advantage of blocking more light and drafts. Blinds that sit outside the frame can make your window appear larger, and if you hang the blind above the frame you can keep the fabric off the window.

We do not recommend an internal fit for bedrooms as they always allow light into the room around the blind so only choose this style if no other option is available. Be aware that internally fit Revolution headers will let some light in above the blind as well.


What is the difference between a Standard Roman Blind and Revolution Chain Driven Blind?

The key differences are the headrail, how they are mounted and the way in which the blind is raised and lowered.

A Standard Roman Blind is attached to a wooden headrail which is screwed directly onto your window frame. This blind is raised by a nylon cord which is tied off on a cleat on the side of the window to keep the blind anchored in place.  

A Revolution Chain Driven blind is attached to a metal headrail which has a more sophisticated mounting system.  Small brackets are mounted to your window, and the blind slides into these.  These blinds come with a beaded plastic cord which hangs off the side of the blind - this is pulled to raise/lower the blind.

This header is required for blinds for over 2m in width as they can hold more weight - they are also ideal for rental properties or situations where the blind will be subject to more use.  The chain will be white unless requested otherwise. 


Should I have my blinds lined?

All roman blinds are required to be lined, so you need to choose between thermal and blackout lining.

Thermal lining provides insulation, keeping your home warm in winter and cool in summer. Blackout linings have the benefits of thermal lining – but also are great to block out any light – excellent for bedrooms or if you enjoy watching TV in the dark.
