Decide which way you'd like to install your blinds, inside mount or outside mount. Measure by the following instructions: 

 

Inside Mount

■ Install within the window frame. 
■ Often used in Bay Windows, or windows with windowsill.

Inside Mount Measurement

STEP 1：Measure the in frame width
Please measure the width of installing headrail as the width of blind.

STEP 2：Measure the in frame height 
Please measure positions of top, middle, and bottom. Record the miminum figures of these three, and that is the blind height.

STEP 3:  Measure the depth of window frame & the thickness of handle bar exceeds window frame. 
Depth of window frame — thickness of operating bar exceeds window frame  ≧ 15cm, the blinds can fit in the frame. 

 

■ Minimum size unit: 0.5cm
■ The shape of window may not be vertical and level. It is suggested to measure three positions of height and width to avoid 
    unseccessful installation. 
■ Reducing 0.5~1cm is suggested for customized width. This is to leave some space for possible alteration in installation work.
■ The thickness after drawing blinds to left and right sides hinders some area of daylighting.
   For full daylighting, outside mount is recommended.

Outside Mount


■ Install on the surface, wall, or ceiling beyond the range of frame.
■ Can cover the window completely, hide window frame, increase covering area and reduce light leaking in 
   from surroundings. 
■ Can hide window shape and adjust visual effect of th space.
■ Common installation. The thickness of blinds after drawing to the right andleft sides doesn't hinder the area of daylighting. 

 

Outside Mount Measurement

STEP 1 Decide the length of blind:
Measure the in-frame width + extra width expected to cover = width needed

STEP 2 Decide the width of blind:
Measure the in-frame height + extra height expected to cover = height needed

■ Minimum size unit: 0.5cm
■ It is suggested to add more than 7~10cm all around the window frame. The actual extra covering area depends on the conditions
   of the space or visual effects requested. 
■ If installed in the curtain box, reduce 0.5~1 cm on customized width is suggested to keep some space for possible alteration in 
   installation work. 

■ For installation of French window or on windowsill. it is suggested to reduce 0.5~1cm on the customized height to leave some
   space for possible alteration on actual installation work.
