If you just need a quote, you only need to send us approximate measurements. 

However, some choose not to pay for our on-site measure + install service, so this page has instructions on how to accurately measure windows yourself.

Inside-Mount Blinds

The most common option - the blind fits inside the window frame. 

1. Measure the inner width of your window at the top of the window frame. Record this as 'Width'.

(e.g. 1452 W) 

2. Repeat for the height of the window. Record this as 'Height'. (e.g. 903 H) 


3. For Vertical, PVC Venetian, or Aluminium blinds, take height measurements from two or more spots and use the smallest.

Note: The maximum width for most blinds is around 3m. If you window is wider, you will probably need to split it into two or more blinds.

Tape Measuring

Tips for 

Important: Use a metal tape measure. When measuring, ensure it is fully straight - it helps if someone else holds the other end. Record measurements to the nearest mm, and do not make any changes or deductions.  

(E.g. Rounding 1583mm to 1580mm could cause issues.)

Minimum Window Depth

Check that your window is deep enough to fit the blind into, also bearing in mind any obstructions such as handles. If your depths are less than the following, let us know and we will inform you of your options.

  • Roller Blind (50mm)

  • Double Roller Blind (105mm)

  • PVC Venetian (70mm)

  • Aluminium Blind (30mm)

  • Vertical Blind (75mm)

Outside-Mount Roller Blinds

Used for all Roman blinds. For all other blinds, inside-fit (as above) is the standard option, but you may prefer outside-mount when:

  • Your window depth is very shallow

  • You want the blind to cover a larger area, leaving no gaps around the edges.

  • Your window is irregularly shaped, (e.g. sloped, arched)

  • There is an obstruction (e.g. handle) which the blind will hit.

1. Measure the entire area which you wish to cover. Record this down as Width x Height. (e.g. 1482 W x 933 H) 

Note:  For most outside-fit blinds, the width should not go beyond the window frame. This is because the blind is best mounted to the wooden frame rather than the wall. 

The exception is Roman blinds and curtains, which are usually fixed to the wall above the window. (Check beforehand that the part of the wall where you will fix the brackets is solid, not hollow.)

If your windows are a bit complicated, feel free to email us an image of your window, or request an on-site measure by our team instead.


1. Measure the inside width and height of your window to the nearest mm.


2. Measure the same window again in two or three different places. Then, record the smallest of the three measurements

If there are multiple panes, also measure the distance between the centre of the mullions (dividing bars) and the frame.

After you send us your measurements, we will give you two quotes:

  • One includes an in-home installation by our shutter team

  • One for pick up and self-install (lower cost, but only recommended if you have renovation/DIY experience.)

If you choose the DIY option, please follow the instructions below:
