In this video, Michael takes you through the super easy process of How to Measure your windows for both an Inside and Outside mounted Roller Blind and explains the importance of roll direction.  In addition, Michael shows you how to measure for a door. The measuring process is exactly the same for both chain drive and motorised blinds.

Handy Hint:

Always work from left to right across the window and move clockwise around your home when taking your measurements. 

Inside Mount

Inside Mount

Window recess depth required for a flush inside mount is 60 mm

Measure the hard width at the top of your window inside the window recess.

*It is important that you take your width measurement from the top of the window as this is where your brackets will be fitted.

Next measure the hard drop from the inside top of your window to the inside bottom of your window.

Generally, inside mounted roller blinds are Front rolled, which means that the fabric rolls of the front of the roll tube to avoid any knobs, winders or the inner window frame that may obstruct the blind.  This will also create a softer, more balanced look.

Decide on your blind control operation – Chain Drive or Motor

Choose which side you would like your controls – Left or Right

Outside Mount

Outside Mount

If your roller blind is to be Outside mounted, measure the width from the outside edge of the architrave to the outside edge of the architrave at the top of the window frame.

Next measure the hard drop from the top outside edge of the architrave to the bottom outside edge of the architrave.  This measurement may be increased if you want your blind to drop past the bottom of your window frame or to the floor.

Back rolling is generally used for outside mounting to keep the fabric tight to the architrave for maximum privacy and greater light control.

Decide on your blind control operation – Chain Drive or Motor

Choose which side you would like your controls – Left or Right

Finish off your look with a stunning Pelmet 95.  

*Please note: iseekblinds will not make any deductions for Outside Mounted Blinds

Roll Direction

Front rolled, which means that the fabric rolls of the front of the roll tube like a waterfall to avoid any knobs, winders or the inner window frame that may obstruct the blind.  This will also create a softer, more balanced look.

Back rolling, is generally used for outside mounting to keep the fabric tight to the architrave for maximum privacy and greater light control.

Michael's Tips

  • Always use a steel tape 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.
