Please provide following information: If possible use a metal measuring tape for accuracy. 

Provide all measurements in mm or cm's. 

You will need to know if you want your blinds to sit inside the window frame (inside recess) or outside the window frame (outside recess) 

We will need 3 measurements in order to manufacture your blind - Width, Height and Installation Height. 

Recess Blinds: 

Measure from the inside wall of the window to the other. (At 3 points - Top, Centre, Bottom) 

Measure from the inner top of the window to the windowsill. (At 3 points - Left, Centre, Right) 

Measure from the top of the window frame to the floor, this will determine the length of your chain as it will need to adhere to the child safety guidelines. 

Measure the full width you want the blind to cover (The exact width refers to overall bracket to bracket size,) 

Measure the length you require overall, including the top fittings and the required overlap past the windowsill (Remember to allow for any obstacles or obstructions beneath the window. It is recommended 10cm above and below your window opening) 

Measure from where you are wanting to fit the blind to the floor, this will determine the length of your chain as it will need to adhere to the child safety guidelines.
