Things to Remember
- Always use a steel tape for accuracy - make sure the tape measure is straight and tight when you take your measurements
- Always measure in millimetres (mm)
- Measure all windows, even those that appear to be the same width and height
- Do not take any deductions (We will do this for you)
Inside Mount
Generally inside mounted roller blinds are front rolled which means that the fabric rolls off the front of the roller tube to avoid any knobs, handles, winders or the inner window frame that may obstruct the blind (refer to the images below).

To measure a roller blind on the inside of your window frame you need at least 60mm depth for a flush mount.

Outside Mount
Generally all outside mounted roller blinds are back rolled to ensure the fabric stays tight to the architrave for maximum privacy and light control.

To measure a roller blind on the outside of your window frame measure the width from the edge of the architrave to the edge of the architrave at the top of your window frame.
Measure the drop from the top of the architrave to the bottom 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.

Roller Blinds NZ will not make any deductions for outside mounted blinds.
Multiple Roller Blinds Together (Sliding Doors)
The same applies for multiple blinds as per the instructions above however, in this case you can mount the brackets back to back. If your window frame has three equal panels measure the overall distance and just divide by three.
If your sliding door or window panels are not equal, measure each section one at a time. The combined measurements that you give should be the same as the overall width. Once again measure the drop as per the instruction above.
