Handy Hint:  

Always work from left to right across the window when taking your measurements. 

Step 2: Linked Layouts

For larger windows or sliding doors, use in conjunction with your check measure worksheet to select the Link Layout best suited to your window.

Handy Hints: 

Using a grey lead pencil simply mark the spot inside your recess directly over the centre of a natural break in the window, the centre of doors that butt together or the centre of the overlap between two doors.

Whichever layout you have selected the measure process is the same.

Now starting from left to right, write down what each blind width is individually as this is how they are going to be ordered.

Remember the individual widths that you write down must equal the overall width of your window.

If an individual blind, or your combined overall linked width is greater than 1800 mm, iseekblinds recommends a spring assist for each blind

Michael's Tips

  • Always use a steel tape measurer or a laser measurer for accuracy - make sure the tape measure is straight and tight when you take your measurements.  Remember you can be 1 mm short, but you can't be 1 mm too long.
  • From the front door, turn left. This becomes window 1 and then work clockwise. Repeat upstairs if required. Add your room name to each of your blinds as you order them.
  • Measure at the top of the window frame where the blind is to be installed.  This is where your brackets will be placed.
  • In your open living areas, always try to fit your blinds inside the window frame.  You will require a window recess depth of at least 60 mm.
  • In bedrooms, inside mount your sunscreen blind and outside mount your block out blind.  This will provide you maximum privacy and room darkening.
  • If you’re mounting a single blind on the outside of your window frame, consider finishing off your look with a Pelmet 95.  Not only will it look great, it will hide the tube, whilst stopping dust from collecting on top of the blind. 
  • All blinds over 1800 mm wide should be ordered with a spring assist.  This will ensure your blinds glide smoothly up and down with minimal effort and will limit wear & tear on the components.
  • If you live near the coast, order your blinds with stainless steel chains.

Handy Hints

  • Always measure in millimetres (mm)
  • Measure all windows, even those that appear to be the same width and height
  • Do not take any deductions (iseekblinds will do this for you)
  • The measurements provided by you will be taken as the outside edge of the roller blind bracket to the outside edge of the roller blind bracket - not the fabric width. 
  • If, in some instances, you are measuring fabric width only, then add 30mm to the total width of the fabric as your finished blind size.  This will become your order size.  Contact iseekblinds prior to placing your order if you are not sure or require further advice.
